I have a Sony VAIO laptop VPCEA4S1E running Windows 7 Home Premium (64bits).
Since a couple of days I have a strange keyboard problem: some keys (1, 3, 5, 7, 8, 9, p, Backspace, F1, F3, F5, F7, F8, F10, F12) are not working as expected.
I have installed the tool ShowOff to display every keystroke.
Pressing the following keys results in some different (series of)keystrokes:
1 -> F1 1 F1
3 -> F3 3 F3
5 -> F5 5 F5
7 -> F7 7 F7
8 -> F8 8 F8
9 -> F10 9 F10
p -> F12 p F12
Backspace -> Backspace Insert Numpadlk
F1 -> F1 1 F1
F3 -> F3 3 F3
F5 -> F5 5 F5
F7 -> F7 7 F7
F8 -> F8 8 F8
F10 -> F10 9 F10
F12 -> F12 p F12
I tried uninstalling/reinstalling the keyboard in device manager.
I tried booting in safe mode.
I reinstalled SONY drivers.
I did a system restore before the day that this problem came up.
Nothing solves my problem.
Virtual onscreen keyboard is working fine.
Hoes anybody any further suggestions? Thanks!
