Please help me, USB Devices instantly disconnect/reconnect when using keyboard

I own a Lenovo 3000 C200. IIf I start typing while I have any USB device plugged in (USB mouse, Removable HDD, etc), the USB device instantly disconnects and reconnects again. As long as I don't touch my keyboard, the USB device will work fine. I have noticed that this does not happen when I press the the other keys like the Lenovo care button, volume increase / decrease key, etc. and doesn't happen when I use the touchpad. I have not dropped or damaged my machine in any way.

At the beginning, thinking it might be a windows problem, I had re-installed windows (XP) with no drivers installed and the problem persisted. I installed the latest update available for the BIOS still with no luck. I have checked the BIOS, however there is nothing related in anyway that can be configured.

Just now I have noticed that the problem begins, as soon as I turn on the machine. Hardware problem perhapsI

 

Please help me.

Same problem here!

 

I already tried removing the USB devices in the device manager, de- and re-attaching the keyboard from the motherboard and installing different USB drivers.

 

 The warranty just expired, what a coincidence....

This happened to me exactly the same, you must updated the latest bios version 2.06.

Now go to the Lenovo website to download the oldest version 1.02  and the 1.08, first flash the 1.02 then flash again using the 1.08 that it, don't use the 2.06 which is the porblem source file for some 3000 notebooks.
