Hi all,
I have a broken Compaq Armada 1510, and of course, the internal PSU *appears* to be shot.
The laptop does nothing when I try to power it on. When I disassembled it to have a look at the PSU, I found that it was connected to the motherboard via two black and red wires.
The first thing I checked was whether the red wires were common to each other, and whether the black ones were also commoned. They were.
The PSU appeared to be just a regular DC PSU that was just inside, there were just black and red wires, which means that its output isn't controlled by an extra pin like it is on ATX PSUs.
It had a label on the side that told me the voltage (18v 2a) so I hooked it to a multimeter and checked the output. It was just 1 volt.
Should I attempt to re-cap it? Is there any resources I can look into?
But further, as a test, am I alright to hook a PSU with a similar voltage to the connector and see if the laptop turns on? The thing I'm stuck about is whether the voltage needs to be exact. Obviously, the engineers of this expect only that specific PSU to be used, so maybe the input isn't regulated.
Any thoughts?
