I have a user on another forum, who thought he may have a USB problem, so called up the Dell helpdesk where he was told to re-install the drivers. Result is, he uninstalled and now cant work his mouse or keyboard. It's an E521 which doesnt appear to have any PS/2 sockets. Anyone know of a workaround?
He mentioned getting into Safe Mode, so he must have some keyboard functionality. So Ive told him to try the F11 approach or use his Recovery disk to Repair. Failing that, he may well have to create a DOS disk and download the BIOS update from Dell onto his working pc, though I think his level of know how is low.
