I was using a Compaq laptop, around 3-4 years old, when I went to have lunch(about twenty minutes or so), & when I came back it was completely shutdown, no lights or anything. It had a battery supply so even if it came unplugged the battery should have kicked, & its about a two hour long battery. when I tried to turn it back on, nothing happened. I checked all the cords, tried 2 turn in on again, still nothing, all lights off.
