Ok, i inherited a Compaq Presario V2000 laptop from a friend at college because it wouldn't start and his parents were buying him a new one. I'd like to fix it if possible, but it will not power on. When the power button is pressed, there is NO response from the machine. No lights, no sounds, no nothing. Now i have searched around other forums and others people with (possibly) similar problems say it could be the CMOS battery. My own theories are the battery being completely dead, or the power source being dead. Does anyone know what i could check, or have any other ideas? Thanks.
