I'm confused. It restarts when you 'plug the battery in'? As in you remove the battery? And then attach it again?
If this is correct: don't do that. There's no need to take the battery out.
When using the laptop while plugged into wall power like a regular desktop pc, it operates normally. When the battery is installed (while still connected to power) the laptop restarts, repeatedly, until the battery is taken out of the laptop.
Not sure what you mean by reset. I assume you are going through the start up routine when you switch to the battery and everything works fine after that.
My laptop will restart repeatedly if the battery is inserted. It will go through POST, then restart.

As Pruzhany mentioned in post #2, you need a new battery and as gguerra mentioned in his post, do not use the battery at all if you typically have the AC power connected and use it like a regular desktop. Keep the battery in a safe place inside an anti-ESD.
If you will need to use the battery. Power off the laptop, unplug the AC cord. Insert battery then plug in the AC power cord and let it charge for at least an hour or two before use.
PS. There is the remote possibility of the chip inside the laptop being bad, the battery sensor- charge controller that determines the charge status of the battery and lets the AC divert charge to it or there might be some other short but the short typically will occur within the battery due to its being defective.

This is needlessly confusing:
- Laptop without battery installed, works fine plugged into AC, correct?
- Laptop with battery installed AND plugged in AC outlet, reboots, correct?
- Laptop with just battery installed, does it work?
- You're not installing/removing the battery while the laptop is up and plugged into the AC outlet, are you?

Does it work fine with the battery alone without being plugged in?
I've seen something similar with a bad external power brick and uncharged battery. The brick didn't supply enough juicy to charge the battery and power the laptop at the same time. I don't know if it was technically the laptop, the brick or battery that was bad.
Since you already tried changing the battery, try charging the battery with the unit off, then see if it constantly reboot, when plugged in and the battery installed.

no. anytime the laptop battery is in, it reboots repeatedly.
I apologize that this posting turned out to be for more confusing than I anticipated.
thanks again for the response. Let's assume I'm slightly (only slightly) more knowledgable than an average user. What point should I be reflowing on the motherboard? Or would replacing the motherboard do it? Or is this a function of the power board?
If you really want to troubleshoot. Every CPU chip has a reset line. If you pull the chip specs it will tell you which pin on the chip is reset. That is your starting point. That said I agree with the other poster that said it is difficult to repair today's motherboards to the component level.

No problem.
OK so there are really only 2 obvious issues that could cause this. The battery is shorted out and causing it or the connector on the motherboard for the battery is going bad. You're only option is to try a new battery for anywhere from $50-$100. Replacing the motherboard to fix this isn't worth the time or cost or effort.
thanks for the response, I've already replaced the battery. I should have mentioned that.
They already tried a replacement battery.
So I'm guessing it is the motherboard.
If you leave your computer in the bios menu with the battery installed, does it reboot? I'd try burning a Linux live CD/USB and run a different OS with the battery installed if I wanted to test if it was the OS and power management/software/OS issues.
My bad. I've never hear dof software causing something like that, Lopez. Not that it couldn't, but I doubt it.
Bad mobo. Either deal with it or get a new laptop. Seriously, a bad mobo isn't something most people should try and replace.
