My Compaq laptop is not booting up. I press on switch. On switch lights up. Laptop makes a little sound for 3 seconds then just goes quiet. Nothing on screen at all. Does not get as far as start of boot up. No curser. Tried plugging in a monitor to prove its not screen problem. This happened suddenly. If I try few times of on, off, then,off...then suddenly it starts to boot up. But today I have repeated this many more times but its not working. Batter stopped holding a charge ages ago. Any suggestions?
It looks like it could be a hardware problem with the power circuit on the motherboard. It could also be a problem with the memory chips. I suggest you try removing them one at a time to see if that gets the computer to boot.
It's probably cheaper to buy a new laptop than try to get the current one fixed. Since it's probably $100 to just get a diagnosis.
