Hi and welcome to Just Answer. My name is XXXXX XXXXX have been repairing Computers Professionally for over 13+ years and currently own a Shop in FL.

Are you saying that this all started after installed a 3rd Party Battery?

If so, that would not of had any effect on the Bios's Firmware. It's sounds like a internal Hardware issue. Remove the Ram Memory and reinsert it. Check that the CMOS Battery is good and reading over 3 Volts DC Power. Remove the Battery and have just the Power Adapter plugged in and power on the Sony. Replace it with the old battery and try it again as well. Let me know the results. Thanks, Carl

The Battery came with a disk that over wrote " patched" the existing BIOS

I found this warning in looking for a fix

http://www.wimsbios.com/forum/topic11992.html

There are sellers on Ebay offering aftermarket batteries for the Sony Vaio VGN-AR series.

These batteries come with a BIOS update file that is supposed to allow the system to work with thier new "aftermarket" battery.

Oh I know what your referring to. It threw me off when you said that the battery installed the software but you ran their "Update" disk and it bricked your Bios.

Usually in this case you can sometimes get a hold of a Bios Bootloader and Bios Update file and burn it to a floppy and sometimes to a CD but I am not able to locate these files for this model. It seems like Sony has created a Proprietary Bios Software and doesn't want to give it out to anyone. You may have to send this off to them and have them put the BIOS on a programmer or use their software to recover the OEM Flash. The only problem is that they may charge you the same as a new Motherboard. I would get some prices from them first. If it's under warranty, you can just tell them that it quit working and wont power on anymore and get it fixed for free.

Hi John, Thank you for your expertise and, more important, for your kindness because they make me, almost, look forward to my next computer problem. After the next problem comes, I'll be delighted to correspond again with you. I'm told that I excel at programing. But system administration has never been one of my talents. So it's great to have an expert to rely on when the computer decides to stump me. God bless, Bill
