I installed SP3 for XP (again!) recently and this time my Belkin wireless link still worked afterwards. Now the HibernateStandby mode is a problem. I think the hibernate info file is made on hibernation, but I have to select the message 'delete restoration data and proceed with restart?' on startup to get any further. This results in a reboot, which is fine, but I am struggling to find the fix to restore the correct function. It may be the BIOS needs upgrading, but DELL doesn't make that easy for a non-expert. I suspect the hibernate file is either corrupted every time (?) or is not recognised at power on. Any ideas, apart from going back and removing the Service Pack 3 upgrade?
