Lenovo 3000 C200 and USB disconnecting problem

[thoona]

Hi all, I have a Lenovo 3000 C200.

I have the problem where when there is USB device plugged in and a key on the keyboard is pressed it is disconnected/ejected.

I've tried updating BIOS just just get a BSOD!

I have searched till I'm blue in the face for a solution and just can't find one.

Any advice would be appreciated.

Cheers,
Rob

This problem is known on the Lenovo 3000... you might look on the Lenovo or Thinkpad sites for more assistance on how to resolve it. But There are some major defects that appear on some Lenovo 3000 system boards.

The only possible explanation can be hardware problem. it happens only keyboard is damaged and the key functions don't work properly.

Well I fixed the problem; I downgraded BIOS then applied latest and it worked!
