Broken laptop keyboards are not fun to deal with.
First, you need to figure out what’s wrong. Is your keyboard is still powered on? How many of the keys are still functioning? If some keys work and others don’t, the issue can be mechanical.
Are none of the keys responding? Press Caps Lock to see if that key’s indicator light goes on or off. If the lights associated with each key don’t turn on and off when you press them, the first thing you should do is restart your computer. If rebooting your machine still doesn’t seem to solve the issue, then bring your device over to PC Mobile Fix and we’ll repair it for you.
