Age Of Sony Vaio Pcg-9h4l And How To Bypass Password At Start-up

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.


  1. BIOS passwords on laptops are hard to get around, you’ll need to provide some proof that you own the computer as well as pay Sony to reset the password (you can’t do it yourself with laptop BIOS passwords, not even if you remove the soldered in CMOS battery).
    If you don’t care about the computer itself but just the stuff on it then you can take the hard drive out and with an adapter (any decent computer store should at least know what you’d need to run a laptop hard disk in a desktop computer) connect it to any desktop computer (assuming he hasn’t encrypted the drive which is pretty uncommon).
    To figure out how old it is you could try googling the model number.

  2. the answer you selected is true. if you do some research you will find that the info. of the bios that you want to bypass is on a chip called eprom and it is not volital, so it does not need electricity from a battery to remember that password (it will be safe for 20 years) and it could go the same with the hard drive. i short circuted one before in order to clear that password. before you do that, do you know if its for windows dose it show something nice or is it really simple looking almost blocky.
