USB Mouse and Keyboard Stop Working E73 Win 7 Pro

We have about 40 E73's in our office.  At least once a week one of the PC's has an issue where both the mouse and keyboard stop working.  We are using Win7 Pro.  Both work until the boot up process gets to the first Windows screen (Contrl/Alt/Del to unlock the PC)   This stops the boot up/windows start process as there is no way to do wnything.  We have to do a hard shut down of the PC.  The only solution we have found so far is a restore of the system to factory defaults.  Not an ideal solution as it takes to much time and effort.


I have not been able to find a better solution to the issue.  Anyone?

Re: USB Mouse and Keyboard Stop Working E73 Win 7 Pro

Is that the Lenovo usb keyboard and mouse it came with?  Do you have systems with those from after-market, and do they have same problem?   Are you up to date with Chipset (USB ports) driver and BIOS?
