So, we bought a Acer Aspire 5560 laptop for my wife and one day while I was at work, she reported that she broke her battery. The battery was stuck at 5% charge and even though it was plugged in, Windows was reporting "Battery 5%, Won't charge." After a number of reboots, and removing and inserting the battery, I promised I'd take a look at it that night.

After a number of searches, we found something that worked. Shutdown the laptop, removing the battery and unplug the power brick. Press and hold the power button for two minutes. I held it for 3 minutes, just to be sure. Replace the battery, and plug in the power brick, and with luck, you should get a charging light now.

The idea is that even though the battery and power brick are removed, there's still enough residual charge left in the internal capacitors for the laptop to remember the incorrect battery state. Holding the power button drains that charge and resets the state.
