I am using a Toshiba Satellite L305-S5875.
On windows my battery runs for around 2 hours under normal working conditions. While only for 1.5 hrs with Ubuntu under same working conditions. Is it possible that Ubuntu reads the amount of battery life remaining wrong and gives me a false alarm? Is there a way fifure that out?
Also when I hook up to power supply, Ubuntu takes about a minute to realize that the power cable has been plugged in.
