If your máy tính keys are sticky, or some of them are missing, or the keyboard isnt working all, you can usually replace the entire keyboard yourself for between $20 and $60. The operation isnt as hard as you might think, and performing it has the advantage that you dont have to remove and replace each key individually. Though every máy tính is different, removing your laptops keyboard usually involves simply unsnapping a cover, removing a few screws, and disconnecting a cable.
If youre up to the challenge, you can tackle this project in the comfort of your own home. Take care, though: A working máy tính is a terrible thing to waste, and PCWorld accepts no responsibility for any damage to your machine that might occur if you try to take it apart. Furthermore, if duplicating our process requires actually opening your entire laptopif, say, you have to remove anything more than a handful of screwsyou should call a professional. And finally, before you do anything else, check to see whether the máy tính is still under warranty. If it is, you may be able to get it replaced for không lấy phí.

Find a Replacement Keyboard
The first step of the replacement process is to obtain the right keyboard for your máy tính. Compare prices by checking eBay, Google, and trực tuyến stores that specialize in replacement hardware, such as

Make sure that the keyboard you buy is for your laptops exact model number, which you may find printed on your screen bezel or on a label attached to the underside of the máy tính. You can simplify your search further by specifying the keyboards part number, which you may be able to find on the máy tính manufacturers website or by calling their tư vấn/service department.
Replacing the Keyboard
For more-precise instructions on how to replace your particular máy tính keyboard than the general steps provided here, check trực tuyến. Theres a small chance that your máy tính is unique and has a very different replacement process from the standard one outlined here. Check with your máy tính manufacturer and with the site where you bought the replacement keyboard to see whether they offer specific instructions for DIY repair. Some manufacturers provide service manuals with detailed instructions on a variety of servicing tasks; if not, try searching the Web for how to replace keyboard with your laptops model number.
Now lets get started! Confirm that you purchased the appropriate replacement, by placing the new one on the máy tính, and seeing if it appears to be the right shape and size. Next, gather your tools: a small Phillips screwdriver for removing the small screws, and a butter knife or other small, thin, flat tool for prying off any covers.
Make sure that the máy tính is powered completely off: Unplug the power cord and take the battery out.
Usually a removable cover or trim piece offers access to the keyboard.
Examine the cover/trim piece that sits between the keyboard and the screen; it usually affords access to the keyboard. Check for and remove any screws that appear to be helping hold the cover piece on. Some pieces also cover the screen hinges, which may have small screws on their backs.
Before removing the cover, be aware that it may have a data cable on the back thats connected to the máy tính. This cable is important and usually doesnt have much slack, so be very cautious when removing the trim piece that holds your laptops keyboard in place. You dont want to rip the cable from the máy tính and ruin the connector or the cable.
A data cable attached to the máy tính may lie under the cover or trim piece.
When the cover is loose, gently remove the cover/trim piece with your bare hands; if necessary, carefully use a butter knife or other thin flat tool to pry it up. The cover should snap off fairly easily with a small amount of forcedont use extreme force or you may break it. If it doesnt seem to be coming off, recheck for any remaining screws that may be holding it oneven underneath the laptopand remove them.
Once youve removed the cover/trim piece, set it aside. If its attached to the máy tính via a data cable, carefully try to move it out of the way without damaging the cable. Then find and remove the screws holding the keyboard in place; there are usually two to five such screws, located along the top of the keyboard.
Two screws hold this máy tính keyboard in place.
Before pulling the keyboard up, note that the back of the keyboard attaches to a data cable that in turn is connected to the máy tính. This cable usually doesnt have much slack either, so be very careful when pulling it up. It is crucial to avoid ripping the cable from the máy tính and ruining the connector.
A small flat data cable on the back of the keyboard connects to the máy tính.
Carefully pull the keyboard up (without ripping the data cable from the máy tính) and unlatch the data cable connector, usually by flipping up the small latch on the connector. Next, remove the data cable and set the old keyboard aside.
Pick up your new keyboard, align it (without setting it down), and attach the data cable to the connector on the máy tính, usually by inserting the flat cable as far as it will go and then flipping the small latch on the connector back down to grasp it. With the data cable connected, set the keyboard in place, being careful not to pull or damage the cable in any way. Reinsert the screws to hold the keyboard down and reattach the cover/trim piece, which usually requires a little force to snap back into place. If you removed any screws from the cover earlier, reinsert those as well.
Once youre done with these steps, you can reinstall your battery and boot up the máy tính. If everything went smoothly, you should have a perfectly working keyboard a fraction of the cost of having a professional repair service do the work!
