BSOD and restart with faulty battery?

Question

Hi group.This one is making me hum the "X Files" theme...I did some routine tests on an IBM Thinkpad TP600, and on the nextreboot it failed with a blue screen. Figuring that something in Windowshad broken I restarted in Safe Mode and this worked fine.Determining that the battery light flashing continuously and themachine not running at all from battery power was probably not normal,I removed it.Interestingly, the laptop runs fine (windows came up with "recoveredfrom serious error") with the battery out. I've done some tests on thebattery and it appears to be shorted (0.0V on the terminals, probablybeen in storage too long)Has anyone else ever seen this symptom?Regards,-Aemail add an e to the instrument to email

I bought a used 600E from a local computer store. When I brought it home, it wouldn't boot up. I called the store back and as he had me go into the BIOS and check a couple of things, it eventually booted up. This was on the beginning of a holiday weekend. Well, I noticed the flashing amber light and wondered what it meant, so I went to IBM's site and downloaded the Hardware Maintenance Manual, to discover this was the battery light. I then went into the BIOS and ran system diagnostics. It was showing a problem with the system board. But if I took the battery out, system diagnostics showed no problem. I came to find out that the laptop booted fine without the battery, but would only sometimes boot with the battery installed. BTW, this laptop had W2K.

After the holiday I brought the laptop back to the store to get a replacement battery. When they installed the replacement from a second

600E, it fried that battery (at least that is what they told me). Since they had a second 600E for sale, they swapped out the laptops, and they went and gave me a battery for it a few days later. This 600E still works great now.

So my advice is not to put the defective battery in the laptop, and hope that the charging circuit on your laptop was not damaged.

Thanks :)Its been there for a while, how long are we talking? this is useful asa new battery is over =A370 and he will be upset if it does not fix theproblem..It also has the flashing amber light problem.I speculate that the battery has an "intelligent" chip which onlyallows charging when it has talked to the mainboard, so if it isdrawing excess power then it explains a lot (dragging down the 5v and12v rails and causing glitches)=20-A
