I am unable to logon my packard bell laptop because the keyboard suddenly stopped functioning and prevents me from typing my password. Only a few letters can be typed . The touchpad works. The OS is windows Xp home edition. I would be grateful for any suggestions. Thank you.
Get a USB keyboard and use it to log on. Run updates and verify drivers. Restart the laptop without the external keyboard. If it still does not work then it sounds like someone 'watered' the keyboard or ate something with lots of crumbs that fell amongst they keys preventing proper operation.
If you are adventurous then do some exploratory disassembly/ cleaning / keyboard replacement. If not then off to a repair center for some TLC.
