That's really funny. Sometimes due to a small error devastating problems arise. Thanks god you found the solution though troubled for some days. I will never neglet now onward on batteries. Better change them earlier than to face such trouble.
Thanks for posting your experience.
System battery voltage is low
My main computer at home (a Dell with Windows) was complaining at startup about System battery voltage is low and then I had to press F1 to continue. After pressing F1, it always worked fine. Lazy as I am, I let this go on for months without buying a new battery (which doesn't cost much).
Then one day I think the voltage became too low and I guess the bios settings got errased. The problem was that after running the setup and starting Windows, I now got a blue screen of death with the UNMOUNTABLE_BOOT_VOLUME error.
The problem was that my internet connection went through a modem connected to that computer and didn't work on Linux (at least not out of the box), so I couldn't even solve it with a Google search.
First of all, I went to the repair shop for watches, which is pretty close (my watch needed a new bracelet too) and got a new battery. The battery was easily replaced on the motherboard. It looks like a coin and is easily removed in a few seconds. The same for putting it back.
Of course the battery only solved the low voltage problem and I still got the UNMOUNTABLE_BOOT_VOLUME error.
I tried it with a few Linux cd's (Mandriva and Ubuntu) and those could see the files and partition just fine. I backed up some files I would like to keep and already planned to install Windows again.
Then I tried with the Windows cd to reinstall Windows. During the install I noticed that it detected the current partition as broken/damaged. I figured out that I could maybe repair the partition to make it work again.
So I plugged in my Gparted Live CD and booted from it. I tried to resize the partition by removing a few Megabytes from it. Unfortunately it somehow figured out it should move the whole partition a few MB further (which takes very long) instead of removing some from the end. I aborted the thing and it luckily hadn't touched anything yet. I tried again and this time it actually did what I wanted it to do, I mean removing a few MB from the end.
Anyway, after resizing it, I rebooted again into Windows. It started without the blue screen and fixed some files with the disk recovery util (or whatever it's called) and then it ran completely fine. The issue was fixed thanks to Linux.
Now that I have access to the internet, I found out the correct command to do it with Windows from the Windows CD. At the command prompt from the recovery console you need to type chkdsk /r.

Well, I think your lucky about that.
'Cause the last time the battery of one of my computers went low it didn't warn me. So, one day I've tried to get the PC On and got a bluescreen of death. As I didn't know what to do I bought a new motherboard (as I didn't made the link between the blue screen and the battery). Few weeks later my friend said to me you only had to change the little battery inside... And we've tried another battery on the old motherboard and it did work fine.
Lol it was too late to return the new Mobo so... I kept it.

I once had a similarly frustrating problem with a computer. I was able to boot up my PC but after about 30 sec to a min it would shut down. I'd reboot and same thing would happen. Pulled my hair out trying to figure out what was going on. I thought it was a bios problem. Well after about two hours on the phone with customer service, The CS rep asked me to open up the box and take a look at the motherboard. Turns out one of the capacitors on the board had popped (capacitor is basically a battery). Bad news was I had to wait 3-5 days for the new board to arrive but all turned out well in the end.

Good to know that a capacitor is a battery!! It's a condensator that stores electric energy in a pasive way. Now going back to the battery change, I have lot's of computers that I never ever changed the battery and still work perfect! Just use them with a UPS and they will work much better and protected!
