I have a laptop that the center pin had snapped out of the DC socket, so i replaced the DC socket and tried to power up the laptop but nothing happened. The adapter i was given was a multi voltage adapter not the original adapter that came with the laptop. The adapter is set at 19V which is what the laptop is meant to take and according to the adapter when set at 19V it will output a maximum of 8amps which is fine for the laptop i have which is a Compaq NX9105.
I have measured the voltage coming out of the adapter and it's a fixed 19V, I've also measured the voltage once connected to the motherboard at various stages of the board and there's power going through the components but it just doesn't switch on.
I was wondering if anybody has had experience with multi adapters and whether they just don't work on some laptops? as what i'm, thinking is eventhough the voltage is correct it might not be supplying the correct amps to the board and therefore the laptop is not powering up at all, i'm not even getting a light come on at the front to say that it's plugged in.
