My eeePC was very sick.
On boot, it would spray the screen with random characters. If I did get a desktop, I found that I couldn't type several characters, like v and t.
A USB keyboard worked perfectly with it, though.
I Googled 'eeepc 701 teardown' and discovered how to remove the keyboard.
I carefully released the ZIF connector for the keyboard and cleaned the black contacts on the flat cable with a pencil eraser. After wiping off the resulting grunge with a cloth towel, I installed the keyboard and now my eeePC works once again.
