Does the old battery of an old laptop use a lot of energy when the laptop is connected to AC? Does the power supply waste electricity trying to continually charge an old battery? If I remove the battery, how many Watts of electricity would I save? Would the laptop stay cooler?
The power supply is very hot in both cases. The laptop is a Toshiba Satellite from 2004/2005.
This is a slightly different question than this: Should I remove my laptop battery?, so don't repeat the same answers. I've read about he UPS/power buffer effect, about the life of the battery, etc. I don't care much about the battery and I boot the laptop from DVD. There is no hard disk. I care about keeping the laptop cooler and spending less electricity.
