Latitude E4300: kb not working + slow

Hello,

I try to fix a latitude E4300.
It has several problems:
- int. keyboard does not work (however trackpoint and touchpad work), only an ext. USB keyboard works.
- laptop is slow: in the BIOS setup the response is already slow, mouse is very slow...
- when hitting F8 on the ext. keyboard, you get the windows startup menu.
(safe mode etc.) Response of this menu is also slow.
- windows (XP) does not start at all, you see the Windows startup screen and nothing happens (no BSOD)
- even a recovery cd like "hiren's boot CD" or "I have the password" doesn't start.
Bios: A13
All settings in the BIOS are correct. Changed to default, still the same problems.
I ran diagnostics (F12), but no errors found???
I ran chkdsk on the harddisk (removed HD and put it into an external HD case), errors were found, but corrected...

What can be the reason?

Thanks,

Arjan

 

What happens if you remove / replace the internal keyboard (instructions here) in case there is a connection problem?

After that try with the internal keyboard removed completely.

Genuine Dell keyboards are available on ebay for a reasonable price.

I have disconnected the int. keyboard, and guess what: now the laptop starts without a problem...
I will call Dell to have the keyboard replaced...
Thanks.
