Keypad Doesn’t Work
If none of the keys work on your laptop, there’s a good chance you’ve unseated the keypad connector. These connectors are quite fragile and are prone to unseating from any physical stress on the laptop. Check the manufacturer’s disassembly procedures to locate and reseat the keypad.
If you’re getting numbers when you’re expecting to get letters, the number lock (NUMLOCK) function key is turned on. Turn it off.
Touchpad Doesn’t Work
A shot of compressed air does wonders for cleaning pet hair out of the touch-pad sensors. You’ll get a cleaner shot if you remove the keyboard before using the compressed air. Remember to be gentle when lifting off the keyboard and make sure to follow the manufacturer’s instructions.
The touchpad driver might need to be reconfigured. Try the various options in the Control Panel | Mouse applet.
