I have a laptop that is behaving strangely. When I turn it on, it does everything what it is supposed to do, but after a minute or so I hear a Click and all goes black. It's like it turns off the power. It doesn't matter what the laptop is doing. It also happens when it's just waiting in the Bios setup menu.
Has someone experienced this before? Can it be the power supply? Can it be a cooling problem? Any ideas?
By the way, it's a Compaq Presario Laptop, maybe 3 years old already.
