I think I have figured out how the CapsLock gets stuck on on on the Asus EEE 701 netbook computer. (Hey, I managed a sentence with three on's in a row!). BTW, this is an electronic "stuck on on," because pressing the key does nothing; holding down Shift corrects the problem, but even I get tried of holding down Shift with my pinkie finger while touchtyping elsewhere on the keyboard.
CapsLock gets stuck when the lid of the netbook is closed while the computer is still running. This puts the netbook into sleep mode, but also forces on CapsLock.
As I noted in an earlier posting, the solution is to press Ctrl+Alt+Backspace, which reboots the X Windows managers, and resets the CapsLock to normal. So, don't close the lid; or else shut down the computer before closing the lid.
I don't know why the problem occurs happens. Now that we know the how, maybe Asus can find the why.
