My father passed away recently, leaving behind a refurbished Sony Vaio PCG-9H4L with Windows XP Athlon 4. He was quite the computer geek, running fairly complex Linux stuff on other computes and (I’m assuming) on this one, too. I can’t log into the system because it requires a password just to start up. Any ideas on how I can (a) bypass the start-up password and/or (b) figure how old this computer is to determine if the files in it are even still relevant to what I’m looking for? Unfortunately, the computer wiz gene has skipped a generation and any advice would be much appreciated! Thanks.
