Acer Aspire M5-581T-6405 Battery Not Detected!

[hellohellosharp]

Please help! I read a guide about extending battery life and it involved pressing the battery reconnect button (the battery is integrated so you stick a pin in the hole on the back of the bottom piece). My laptop was off with no AC. I discovered that after pressing it, I could not turn my laptop on anymore unless it was connected to AC. On windows, it said it could not detect a battery. Remove the AC would result in an instant power off.

It seems my motherboard has forgotten it has a battery! (Or I wrekced the battery).

I called Acer support and they told me to hold the button again fro 20 seconds. Nothing happened. Since I had dropped the laptop a long time ago and it had a small crack, they won't service it without charging me $250.

I have tried the following things (yes, I did have to open up the whole machine to do some of these).

1. Reinstalled BIOS from the acer driver website.
2. Reinstalled my OS (Windows 7 64-bit)
3. Disconnected the battery and AC, held power button for 2 minutes, re-insert battery.
4. Powered machine down, disconnected AC and battery, held power button for 2 minutes, re-insert AC, pwoered computer on, left for 5 minutes, re-insert battery.
5. Left charger in laptop for 24 hours.
6. Unistalled windows battery drivers multiple times, connected battery, restart, re-install drivers.

I have dilligently tried every suggestion I have found and nothing works. I am now under the impression that my laptop battery could be broken. Is there a way for me to test the battery to actually see if it works?

Here are some pictures:

After everything, the battery light never came on

The solution provided by Shane Andrews worked perfectly.
Shane Andrews, thank you big time man, you saved my girlfriend and me.
I'm a computer technician myself, and I just couldn't figure out why the notebook wouldn't start with just the battery after dusting the thing.
As I always test devices while they're open, I didn't think of having to reassemble it. Thank you!
