Today I had a laptop that was brought to me that seemed to need a new power jack soldered onto the motherboard. After some investigating and diagnosing the laptop I determined that the AC Power Adapter was putting out way to much Amperage for the motherboard to handle. So with this being said I wanted to write a few tips on how to purchase the proper power adapter for your laptop.
Voltage, amperage and the jack it self needs to all match. In the case above the adapter was 7.1Amps and the laptop needed NO MORE then 6.7Amps. So it was frying the motherboard. At least in the example above, replacing the power adapter with the proper one, fixed the issue entirely.
