In almost all cases the user guide contains instructions for restoring to factory settings. Go to Sony's web site and download it if it's not on the hard drive (as it usually is).
I recently found a discarded Sony Vaio laptop that uses a German keyboard configuration and belonged to a company of some sort and so obviously I can't log on and I'm trying to restore it to it's factory settings so I can make a new user profile. I've tried hitting Alt+F10 during boot up which was suggested to me but it didn't work and I can't access the boot menu.
I'd appreciate any help as the laptop is in good condition and I'd like to have a backup laptop with XP. Thanks
