Keyboard Will Not Respond ¶ 

The Entire Keyboard Is Not Working ¶ 

The first step is to reboot the laptop. If keys cannot be used to reboot, hold the power button for 15 seconds to turn the laptop off. After the laptop has turned back on, see if the keyboard is working by checking if the LED light turns on when you press Numlock, Caps lock and scroll lock. If that does not work, press the Esc key repeatedly to see if a startup menu opens. If the keyboard is still not working after it is turned back on, then the keyboard is defective and needs to be replaced. See replacement guide

Stuck Keys ¶ 

One method to fix this is to take out the key and see if there is anything under the key that is holding it in place. Another approach to solving this problem is using compressed air and spraying to see if there is any dirt in between or under the keys. A third approach would be to use a screwdriver to take the key out and clean the key, then put the key back on the keyboard.

Hardware Malfunction ¶ 

A laptop can experience hardware malfunctions which would cause it to shut on and off multiple times. One approach to fixing this problem is to remove the hardware that can be removed (such as the USB drive and cameras) and then put each component back one at a time to see which one is faulty. Once the faulty device is figured out try to uninstall and then reinstall it, which should solve the problem.
