Hello guys,
Please go easy on me, as I am new to a lot of this.
I have a Sony VGN-FS500 laptop that I am trying to repair. The original problem with this was that the DC jack was all worn out from having the AC adapter cable yanked out of the side of the laptop, thus causing intermittent charging. Over time, the connection was so bad that it wouldn't even charge the battery while powering the laptop at the same time. I took it apart and temporarily fixed the dc cable to the mother board, reassembled the whole thing and no more loose contacts! It would power up so long as the battery wasn't installed. The laptop still wouldn't charge the battery while powered on, or off.
Eventually I gave up on it . The laptop sat for 6 months or more with no battery in it. I recently went back to it and tried to fix it. Magically, without doing anything to it, it all worked fine, it charged the battery, while powering the laptop, with no problems. So i took it apart to permanently repair the dc cable by replacing it with a new cable from sony. I put it all back together again and voila! I am back to square one. I can't power the laptop up with the battery installed. I get a rapidly flashing battery light. If I plug the battery in while windows is already running, I get an error message indicating the battery is incompatible, and needs to be removed immediately. What happened in those six months to make the laptop think everything was ok enough to charge the battery and power the laptop like normal? Could the CMOS battery have died and been recharged when i powered it up for the first time again?...and forgot the error?
PS I've already updated the BIOS to the latest version...
Any ideas?
Thanks in advance!
