How to Buy New Laptop : 8 Buying Guides

Compact enough to carry with you, yet versatile enough to run demanding applications, a laptop is the best tool for doing serious work or play at home and on the road. While standalone tablets and smartphones are always popular, most people realize that everything from typing a research paper to crunching video to gaming works better on a laptop. So what type of laptop should you get?

There's a wide variety of sizes, features and prices, which makes choosing the right laptop a challenge. That's why you need to figure out what your needs are. To make the right call, just follow these steps.

1. Pick a Platform: Mac, Windows or Chrome OS?

This is not an easy question to answer, especially if you're not familiar with both Macs and PCs. But this quick overview of each platform’s strengths and weaknesses should help.
Most laptops come with one of three operating systems: Windows, Chrome OS or Mac OS X (for MacBooks only). Choosing the right one is a personal preference, but here's a quick summary of what each offers.

Windows 10

The most flexible operating system, Windows appears on many more makes and models than Chrome OS or Mac OS X. Windows notebooks range in price from under $200 to several thousand dollars and offer a wide array of features from touch screens to fingerprint readers to dual graphics chips. Windows 10, the latest version of Microsoft's flagship operating system, provides a number of improvements over Windows 7 and 8, including the ability to switch between tablet and desktop modes, a revamped Start menu with live tiles and the Cortana voice assistant. While it still needs more touch-friendly apps for tablet users, Windows has millions of desktop programs available, including the full versions of the major productivity, graphics, video and development software

Apple OS X El Capitan

All MacBooks come with Apple's own operating system, Mac OS X El Capitan. Overall, the operating system offers similar functionality to Windows 10, but with a different take on the interface that substitutes an apps dock at the bottom of the screen for Microsoft's Start menu and taskbar. iPhone or iPad users will appreciate iOS-like features such as Launch Pad for your apps, superior multitouch gestures, and the ability to take calls and text from your iPhone. However, OS X isn't made for touch, because no MacBook comes with a touch screen.

Chrome OS

Found on inexpensive "Chromebooks" such as the Lenovo 100S Chromebook, Google's OS is simple and secure, but limited. The user interface looks a lot like Windows with an application menu, a desktop and the ability to drag windows around, but the main app you use is the Chrome browser. The downside is that there are few offline apps and those that exist don't always work well. However, if you need a device to surf the Web and check email, navigate social networks and chat online, Chromebooks are inexpensive and highly portable, and they offer good battery life

2. Decide If You Want a 2-in-1

These days, many PC laptops fall into the category of "2-in-1s," devices that can switch between traditional clamshell mode, tablet mode and other positions in between such as tent or stand modes. The 2-in-1s generally come in two different styles: detachables with screens that come off the keyboard entirely and flexible laptops with hinges that bend back 360 degrees to change modes. Most of these systems are much better at serving one purpose than the other, with bend-backs being laptops first and detachables offering a superior tablet experience. However, if you don't see the need to use your notebook as a slate, you'll usually get more performance for your money and a better productivity experience with a traditional clamshell laptop.

3. Choose the Right Size

Before you look at specs or pricing, you need to figure out just how portable you need your laptop to be. Laptops are usually categorized by their display sizes:
  • 11 to 12 inches: The thinnest and lightest systems around have 11- to 12-inch screens and typically weigh 2.5 to 3.5 pounds,
  • 13 to 14 inches: Provides the best balance of portability and usability, particularly if you get a laptop that weighs under 4 pounds.
  • 15 inches: The most popular size, 15-inch laptops usually weigh 4.5 to 6.5 pounds. Consider this size if you want a larger screen and you're not planning to carry your notebook around often.
  • 17 to 18 inches: If your laptop stays on your desk all day every day, a 17- or 18-inch system could provide you with the kind of processing power you need to play high-end games or do workstation-level productivity.

4. Check That Keyboard and Touchpad

The most impressive specs in the world don't mean diddly if the laptop you're shopping for doesn't have good ergonomics. If you plan to do a lot of work on your computer, make sure the keyboard offers solid tactile feedback, plenty of vertical travel (distance the key goes down when pressed, usually 1 to 2mm) and enough space between the keys.
Look for an accurate touchpad that doesn't give you a jumpy cursor and responds consistently to multitouch gestures such as pinch-to-zoom. If you're buying a business laptop, consider getting one with a pointing stick (aka nub) between the G and H keys so you can navigate around the desktop without lifting your fingers off the keyboard's home row.

5. Pick Your Specs

Notebook components such as processor, hard drive, RAM and graphics chip can confuse even notebook aficionados, so don't feel bad if spec sheets look like alphabet soup to you.
Here are the main components to keep an eye on.
  • CPU: The "brains" of your computer, the processor has a huge influence on performance, but depending on what you want to do, even the least-expensive model may be good enough. Here's a rundown.
    • AMD A series or Intel Core i3 / i5: If you're looking for a mainstream laptop with the best combination of price and performance, get a Core i5. Core i3 is a small step down. AMD A series CPUs are less common, but promise similar performance.
    • Intel Core i7: High-end performance for gaming rigs and workstations.
    • AMD E Series or Intel Pentium/Celeron: Found on low-cost laptops. It provides just enough performance to enable basic tasks such as video viewing, document editing and Web surfing.
    • Intel Atom: Also found on low-cost laptops and 2-in-1s. It offers basic performance but more battery life than Celeron/Pentium.
    • Intel Core m3 / m5 / m7: Low-power and low heat allow systems with these processors to go fanless. Performance is better than Celeron, but a notch below Core i3 / i5.
  • RAM: Some sub-$250 laptops come with only 2GB of RAM, but ideally you want at least 4GB on even a budget system and 8GB if you can spend just a little more.
  • Storage Drive (aka Hard Drive): Even more important than the speed of your CPU is the performance of your storage drive. If you can afford it and don't need a ton of internal storage, get a laptop with a solid state drive (SSD) rather than a hard drive, because you'll see at least three times the speed and a much faster laptop overall.
  • Display: The more pixels you have, the more content you can fit on-screen, and the sharper it will look. Most budget and mainstream laptops have 1366 x 768 displays, but if you can afford it, we recommend paying extra for a panel that runs at 1920 x 1080, also known as full HD or 1080p. (The difference is typically about $TK.) Some higher-end laptops have screens that are 2560 x 1600, 3200 x 1800 or even 3840 x 2160, which all look sharp but consume more power, lowering your battery life.
  • Touch Screen: If you're buying a regular clamshell laptop, rather than a 2-in-1, you won't get much benefit from a touch screen and you will get 1 to 3 hours less battery life. On 2-in-1s, touch screens come standard.
  • Graphics Chip: If you're not playing PC games, creating 3D objects or doing high-res video editing, an integrated graphics chip (one that shares system memory) will be fine. If you have any of the above needs, though, a discrete graphics processor from AMD or Nvidia is essential. As with CPUs, there are both high- and low-end graphics chips. Nvidia maintains a list of its graphics chips from low to high end, as does AMD.
  • DVD/Blu-ray Drives. Few laptops come with optical drives, because all software and movies are downloadable. However, if you really need to read / write discs and your laptop of choice doesn't come with a built-in DVD drive, you can always buy an external one that connects via USB for under $20.

6. Don’t Skimp on Battery Life

If you're buying large, bulky notebook that you'll use only on a desk near an outlet, you don't have to worry about battery life. However, if you plan to use the laptop on your lap, even if it's at home and or work, you'll want at least 6 hours of endurance, with 8+ hours being ideal. To determine a notebook's expected battery life, don't take the manufacturer's word for it. Instead, read third-party results from objective sources, such as our reviews. 

7. Plan Based on Your Budget

These days, you can buy a usable laptop for under $200, but if you can budget more, you'll get a system with better build quality, stronger performance and a better display. Here's what you can get for each price range.
  • $150 to $250: The least-expensive noteboo
    ks are either Chromebooks, which run Google's browser-centric OS, or low-end Windows systems with minimal storage and slower processors, such as the HP Stream 11 and the Lenovo Ideapad 100S. Use these as secondary computers only or give them to the kids.
  • $350 to $600: For well under $600, you can get a notebook with an Intel Core i5 or AMD A8 CPU, 4 to 8GB of RAM, and a 500GB hard drive, all respectable specs. However, at this price, most notebooks don't have an SSD, a full-HD display or long battery life.
  • $600 to $900: As you get above $600, you'll start to see more premium designs, such as metal finishes. Manufacturers also start to add in other features as you climb the price ladder, including higher-resolution displays and entry-level SSDs.
  • Above $900: At this price range, expect notebooks that are more portable, more powerful or both. Expect higher-resolution screens, faster processors and possibly discrete graphics. The lightest, longest-lasting ultraportables, like the MacBook Air 13-inch and the Dell XPS 13, tend to cost more than $1,000 (although you can get the Dell for less if you don't opt for a touch screen). High-end gaming systems and mobile workstations usually cost upward of $1,500 or even as much as $2,500 or $3,000.

8.Mind the Brand

Your laptop is only as good as the company that stands behind it. Accurate and timely technical support is paramount, which is why Laptop Mag evaluates every major brand in our annual Tech Support Showdown. This past year Apple came in first place, followed by HP and Samsung.This past year Apple came in first place, followed by Microsoft and Samsung.
Support is only part of what makes a notebook brand worth your money. You also have to consider how the manufacturer stacks up to the competition in terms of design, value and selection, review performance and other criteria. In our 2015 Best and Worst Laptop Brands report, Apple placed first, followed by Dell and HP.

How to Fix and Diagnose Hard disk Failure

Your Hard disk is misbehaving or something going wrong ? By this method you will be able to daignose the hard disk issue and FIX IT
Hard disk failures are the most common computer hardware problems. And laptop hard disks fail more often than desktop HDs. If you knock hard or drop your laptop even a few inches while it’s working, you may damage the HD.

Symptoms:

  • The laptop starts as usual but when Windows starts to load it goes to blue screen with either “UNMOUNTABLE_BOOT_VOLUME”, “hal.dll is missing or corrupt” or “WINDOWS\SYSTEM32\CONFIG\SYSTEM” (or similar) is missing or corrupt. All these error messages indicate a filesystem problem. Sometimes it can be fixed by just scanning the HD for errors. However in over 50% of the cases these errors indicate that the HD is starting to go bad and is probably developing bad sectors.
  • The laptop starts as usual but Windows freezes on the initial “Windows XP” screen, although the blue bar continues to move, and you can hear feint but continuous clicking. Hard disk have to be replaced.
  • As soon as the laptop is started there are loud clicks or grinding sounds and Windows doesn’t load. Hard disk have to be replaced.
  • Shortly after starting the laptop a message appears (usually on a black screen) “SMART test failed. Backup your data immediately and replace the hard disk” or similar. Well, that says it all. S.M.A.R.T. is a self-test that is build into the hard disk.
In almost all cases the laptop can be started from a “live” bootable CD and everything works normal. In rare cases the HDs PCB (printed circuit board) may short or even burn. Then the laptop wouldn’t start unless the HD is removed.


Troubleshooting:

The first case from above (corrupted filesystem) is by far the most common. There are several ways of diagnosing and fixing the corrupted/missing files. If this was just a software problem, the hard disk will continue to work properly. However keep in mind that this may also be a signs of deterioration and backup daily!
Also the hard disk will need some preventive maintenance. Check it for errors every few days or at least every week. To do that you must be logged in an admin account, then right-click the “C” drive in “My Computer”, select “Properties”, then “Tools”, then click on the “Check Now” button. Select both boxes and click on “Start”. Windows will tell you that the hard disk cannot be checked now but you can schedule a check for the next restart. Click “OK” and restart the laptop. The check will take from about 30-40 min. to over 2 hours, so do it when you’re not planning to use the laptop for some time.


Note :-

By this Method You can Save the life of hard disk and it can regain its life, If your hardisk had stop working and you want data recovered. so follow this website they provide best laptop service in mumbai

How to repair laptop charger which is not connecting

How to repair laptop charger ?? Confused ?? You can read the below post to get your answer, this method has been checked and working mostly time. You can also visit our website CLICK HERE

When you plug in your laptop, you usually find yourself greeted with a cheerful chirp from your PC, a new glowing LED indicator light, and a display that perks up and beams a bit more brightly. At least that's what it's supposed to do. Sometimes, though, what happens instead is that you connect the AC adapter—usually because the battery is nearly drained—and you get nothing. No glowing lights. No brightened display. And no battery charging. What went wrong? Why won't it work, and what is to be done about it?
It may seem simple enough to recharge a laptop. You plug it in, it works; easy, right? Well, not necessarily. Between the wall outlet and your battery are several steps and parts that can all fail. Some are easy to fix yourself with a software tweak or a new battery, but some problems may require a visit to a repair shop or even a full-blown system replacement. Knowing which is which can save you hours of frustration and hundreds of dollars in repairs. By taking an inside-out approach, you can quickly narrow down where the problem originates and find the most economical solution.
Get ready, boys and girls, it's time to go troubleshooting

1. Are You Plugged In?
It sounds silly, but you need to make sure that the laptop is actually plugged in. No software tweak or hardware repair can make a disconnected laptop magically power on. Before checking anything else, then, you need to ensure that both the AC outlet and laptop plugs are firmly seated. Check the AC adapter brick and verify that any removable cords are fully inserted. Next, make sure that the battery is properly seated in its compartment, and that there is nothing wrong with either the battery or laptop contact points. Finally, find out whether the problem doesn't lie with the laptop at all: Try plugging the power cord into a different outlet to see if you've got a short or a blown fuse.
At this point, we've determined that it's not just user error causing the problem. There is a real issue with powering the laptop; now it's simply a matter of figuring out where the problem may be. That begins with eliminating where it isn't. We'll start with the most common and easy-to-address issues.
2. Lose the Battery
A simple way to check the integrity of the battery is to remove it entirely and try plugging in the laptop. If the laptop powers on properly, the problem was likely a bum battery.
3. Breaks, Burnout, and Shorts
Feel along the length of the power cord, bending and flexing as you go, to check for any kinks or breaks. Check the ends for any broken connections, such as plugs pulling loose or spots that may have gotten chewed by a pet or caught in a vacuum cleaner. Inspect the AC brick. Is it discolored? Are any parts warped or expanded? Give it a sniff—if it smells like burnt plastic, that's likely where the trouble lies.
4. Check the Connector
When you plug in the laptop's power connector, the connection should be fairly solid. If it's suddenly wobbly or loose, or if the receiving socket gives when it should stay firm, the power jack may have broken inside the chassis. Are there discolorations or any sort of burning smell? If there seems to be any damage to the power connector, repairs will be in order.
5. Beat the Heat
A non-charging battery can sometimes be caused by an overheating laptop. This problem is two-fold; with the system shutting down to prevent overheating a battery and causing a fire. Also, as the temperature rises, the battery sensor may misfire, telling the system that the battery is either fully charged or missing completely, causing the charging problems. These problems become far more likely when dealing with older laptops which don't have the quality of cooling technology used today, or when using the laptop on the couch or in bed, with a blanket or pillow covering the cooling vents. Let the system cool down and take the time to make sure that the air vents are clean and unobstructed.
6. Swap Out the Cord and the Battery
These are the cheapest and easiest-to-swap parts on the laptop. A replacement power cable can often be had for under $10 on Amazon.com, and replacement batteries can be picked up for under $100. Replacement cables are most easily found by searching under the model name of the laptop, while batteries often have their own model numbers. Look for a replacement that matches the voltage specifications of the equipment your laptop came with, and be aware that cheap replacement parts from third-party manufacturers may not have the quality of the originals.
At this point, we've eliminated the problems caused by kinked cords or environmental causes. If you still find yourself powerless, the problem lies within the computer itself, caused by either a software issue or faulty hardware. Let's start by looking at the settings and software.
7. Check Your Settings
For Windows Laptops: In the Control Panel, open up the Power Options. Open the plan settings and visually check that all are properly set. Be on the lookout for incorrect settings for the battery, display, and sleep options. For example, your battery settings may cause trouble if you have set the computer to shut down when the battery level drops too low and set the low battery level at too high a percentage. You can also assign actions like sleep and shut down when your lid is closed or the power button is pressed. If these settings have been changed, it's easy to suspect a power malfunction even though there's no physical problem with the battery or charging cable. The easiest way to make sure that your settings aren't causing problems is to restore the power profile to default settings.
For Mac Laptops: In System Preferences, select the Energy Saver pane and review your preferences. Mac settings are adjusted with a slider, letting you select the amount of time the computer can sit idle until it goes to sleep. If the interval is too short, you might suspect battery issues when settings are the true culprit. And don't forget to check these settings for both battery power and wall power.You may want to revert back to the default settings to see if a change in settings is causing the problem.
8. Update Your Drivers
For Windows Laptops: In the Control Panel, open the Device Manager. Under "Batteries" you should see three items, one for the battery, another for the charger, and a third listed as "Microsoft ACPI Compliant Control Method Battery". Open each item, which will bring up a Properties window. Under the "Driver" tab, you'll see a button labeled "Update Driver." Go through the driver update process for all three. Once the drivers are all up to date, reboot the laptop and plug it in again. If this doesn't resolve the problem, uninstall "Microsoft ACPI Compliant Control Method Battery" completely and reboot.
For Mac Laptops: On a Mac you'll need to try resetting the System Management Controller (SMC). For laptops with removable batteries this is as simple as shutting down power, removing the battery, disconnecting power, and pressing the power button for 5 seconds. Reinsert the battery, connect power, and fire up the laptop.
For newer Macs with batteries sealed into the chassis, shut down the computer, but leave the power adapter connected. With the power off, press and hold the power button while pressing the Shift-Control-Option keys on the left-hand side of the keyboard. Release the keys and power button simultaneously, then attempt to power on the laptop.
9. Call in Outside Assistance
If you haven't already, this is probably a good time to contact tech support. Your particular make and model of laptop will likely have its own unique issues, and a seasoned tech support operator will have seen all of them. He or she will likely walk you through many of the steps outlined above, but will also be aware of software and hardware issues specific to your configuration, such as what bits of hardware commonly fail.

10. Problems Inside
When all of your options are exhausted—you've tried other power cables and batteries, you've checked and rechecked your settings, you've fixed any potential software problems—the problem is likely found inside the machine. Several internal parts can cause problems when they malfunction or fail. Common culprits include a faulty motherboard, wonky logic boards, damaged charging circuits, and malfunctioning battery sensors. Like a sick person consulting a doctor, you need to see a specialist. Contact your manufacturer about what repair options are covered under your warranty,

How to Fix Dead laptop Battery by 5 methods

We are the best laptop repair in mumbai and we are giving the tips from this blog to the users and i hope it helps you
Laptop batteries are expensive pieces of equipment, so if you have an old laptop that still works fine, who wants to shell out upwards of INR- 1500-2500 (Compatible) to replace the battery right!? Luckily, there are a lot of ways, some technical, some interesting and some strange ones, that people have come up with to restore dying batteries on laptops.
In this article, I’m going to try to list out all the different ones I’ve read about and if I can remember where I read it, I’ll link back to the original source. If you have tried to restore a laptop battery yourself, let us know your method in the comments.

Method 1 – The Freezing Method

I once saw a movie where a guys’ phone was about to die, so he took out the battery and stuck in some snow, which apparently made it last longer! I still don’t know if that’s true or not, but apparently you can freeze a laptop battery and get more juice out of it. Here’s the procedure very succinctly:
Step 1: Take your battery out and place it in a sealed Ziploc or plastic bag.
Step 2: Go ahead and put the bag into your freezer and leave it there for about 12 hours. Some people suggest leaving it for longer, but I wouldn’t leave it for more than 24 hours.
Step 3: Once you take it out, remove the plastic bag and let the battery warm up until it reaches room temperature. Be sure to wrap it in a towel and wipe away any condensation as it warms up.
Step 4: Reinsert the laptop battery and charge it completely.
Step 5: Once charged, unplug the power and let the battery drain all the way down.
Now repeat steps 4 and 5 at least 4 times: charge all the way to full, then discharge completely. That should be it! Unless your battery is leaking acid, you should get some kind of bump in the battery life.
Hot to fix laptop battery in mumbai

Note that you should only perform this on NiCD or NiMH batteries. If you try this on a lithium battery, it’ll make the battery life worse. Unfortunately, there is no way to restore a lithium battery. You’ll have to find your laptop specs to see what kind of battery you have. For lithium ion batteries, you can’t restore, but you can possibly extend the life of a battery. Read method 2.

Method 2 – Cool Your Computer

If you have a lithium ion based battery, you can increase it’s life by making sure your laptop is cool. If you have a laptop that gets really hot, it can damage the battery and cause the shortness in battery life. I have an old Sony VAIO laptop and I saw a significant increase in laptop battery life when I bought a laptop cooling pad off Amazon

You may think your battery is on it’s last leg, but it could simply be that it’s getting too warm and therefore loses charge faster.

Method 3 – Recalibrate Your Battery

With most newer batteries, this is no longer necessary, but if your battery is dying, then it’s probably a pretty old battery. In that case, you may benefit from a recalibration. Recalibrating a battery is done because sometimes the operating system cannot figure out how much capacity is left in the battery. This can happen if the laptop is always plugged in or if the battery was never let to die all the way.
You can tell whether your battery needs calibration if your battery never charges to 100% (say only to 95%) or if the OS says you have 35 min of battery remaining, but the computer dies either much sooner or much later. A lot of manufacturers have released calibration tools for specific laptop models, so first perform a Google search with your computer model + battery calibration. Here’s an example tool from Sony.
If you have to manually recalibrate a battery, the procedure is pretty straight-forward:
Step 1: Charge your battery to 100% or to whatever max percentage it can reach and leave it there for about 2 hours to cool down.
Step 2: Now disconnect the power and let the battery drain. There seems to be two views about how to do this. You can either let the battery run down all the way until the laptop dies or you can set it so that it goes to sleep or hibernates around 3 to 5%. Either way, you want to make sure the display stays on until it either dies or goes to sleep.
Step 3: Let the computer remain turned off for anywhere between 3 to 5 hours.
Step 4: Turn it back on and let it charge all the way to 100%.
That’s pretty much it. Now the computer should be giving you a more accurate reading of the actual capacity of the battery.

Method 4 – Remove Battery When Plugged In

If you have a laptop with a removable battery, you can try to remove the battery during the times you have it plugged into the wall. You may have to test this because some laptops don’t work properly with the battery removed. However, if the laptop is running fine and it’s connected to a power source all the time, it may help to simply remove the battery.
The chemical reactions will continue to occur in the battery regardless of whether or not it’s in the laptop, but it could increase the life of the battery. Since the battery is cool and not hot when plugged in, you’ll get more life out of your battery.
Of course, you’ll need to make sure you’re not living in an area where the power goes out because your computer will die immediately and you’ll lose any data. This method is also time-consuming and annoying and something most people won’t do. The last method below may be the best.

Method 5 – Unplug at Full Battery

The last option you can try is to let the battery charge to 100% and then simply unplug the computer. When it gets close to dying, i.e. less than 5%, go ahead and plug it in and let it charge up. However, this could reduce battery life on newer lithium ion batteries, so for those batteries it’s suggested you only let the battery level drop to 35% to 45% and then charge it back up to 75% to 85%. Sounds crazy, but apparently that will give you the best battery life because it won’t use up as many charge and recharge cycles.
Again, this method also requires a bit of work, but it’s worth a try if you really want to increase your battery life. Have you used any other methods not mentioned here to increase your laptop battery life? If so, let us know in the comments. Enjoy!

How do I fix a broken laptop key or put it back on?

Note: This document is meant as a general reference guide and may not apply to your laptop, as your laptop may have a different keyboard key design. Every laptop comes with different keyboard

Fixing a loose key-cap

Unlike those on a desktop, each of the keys on a laptop keyboard have three components: the keycap, key pad, and the key retainer, as shown in the picture.
If the keycap is loose but still attached to the laptop, it can often be fixed by pressing down on the keycap. If the keycap re-attaches, you should hear a snap while pressing the key down. If this does not fix the issue we suggest removing the key so it can be re-attached. The re-attachment process is shown below.

Fixing a broken keycap

Note: If a key, keycap, key pad, or retainer is physically broken or missing, it must be replaced.
If you're having difficulty putting a key back onto the laptop, follow the steps below. If you're trying to fix the spacebar, skip to spacebar steps.
1. Start by first inserting the key retainer into the laptop. If you have a key pad like the one shown in picture at the top of the page, we suggest inserting it after the retainer is set in place to make things easier. Once the retainer is inserted, it should lie flat and be able to flex (shown in the image below).
Tip: If you're not sure what direction the laptop key retainer goes, check the orientation of the metal hooks on the base of the keyboard. These metal hooks helps determine the orientation of the key retainer laid into them, as the retainer should align with the hooks.
2. Insert the key pad into the retainer.
3. Once the above two steps have been completed, position the key cap over the retainer in the proper orientation and press down lightly. The key should snap onto the retainer. If the key does not look right, try pressing down on all corners of the key to make sure all clips are snapped into place. Once snapped in, test the key and see if it works again.

Spacebar key steps

Unlike the other keys on the keyboard, the spacebar requires additional steps to get it back on properly. The image below shows the spacebar removed from a laptop. Before the spacebar keycap can be placed back onto the laptop, there is a bar (shown below) that must be removed by inserting your flathead screwdriver beneath it and gently pulling upward.
Once this bar has been removed, place the new spacebar on the laptop, being mindful that it is properly oriented over the retainers, and push down to snap it back into place.
