Laptop Battery Gets Hot When Charging. So theres no real danger of your battery being overcharged if you leave it plugged-in all the time. The hot spot burns a hole which frees up more material that makes more shorts that make more materialYou get the idea.

This is normal as the battery can accept the charge pretty easily at this point and the bubbling will get a bit more audible. The hot spot burns a hole which frees up more material that makes more shorts that make more materialYou get the idea. Its getting hot in here so hide your batteries.
I use the laptop on the battery every 2 week to keep the battery in shape.
The battery backup is not that good. That makes an internal short which makes a hot spot. If not press the power button and then tap the F2 key to invoke the startup menu. Hold down the power button for 1 minute.
