Replace Keycaps or Replace Keyboard

Whenever I need to do any repairs on laptops, I start by going to the manufactures website and look for the support section. I then enter the serial number so I can confirm the model of the device. Once you have this information, you can look for a service manual for the device. A lot of manufactures have these on their website. This should help you with replacing the keyboard and will likely list the part number of the keyboard. If I need to replace keyboards on computers, I typically will get a replacement keyboard from eBay.
