Introduction |
If your Lenovo T420 has intermittent keys or is running loud and you think the problem could be related to dust in the heatsink, this guide will show you how to remove the keyboard from the system.
'''Guide notes'''
* If you are removing the keyboard for fan access, blowing too much air in one shot or being too close may damage the fan. If it is particularly severe the system will give you a fan error and shut off. If this happens you may need a new fan.
* If you are replacing the keyboard, make sure you buy the right one. Tbe FRU on your system should be on the back. However, you can also find the FRU in the Lenovo HMM if your keyboard is original.
* While this is not a hard repair, you may wish to sort your screws. At least when you go this far you only have to deal with two it is particularly bad if the silver screw is lost.
* Watch the ground on the chassis by the RAM door. This can get in tbe way. If this happens push it back into place and it'll be almost as good as new. |
