Chosen Solution
Hi, I plugged a jack into my laptop while it was powered by phantom power. The machine just “snapped” and went black. There is no signs of power, the leds don’t light up. Is there any chance to save this laptop easily, or do i need a new logic board? Thanks
Hi @f0_cus , As a first step, open the laptop and check if you can see any obvious component damage. Given that it is difficult to obtain any schematic diagrams for the systemboard it won’t be easy to replace any obviously faulty part that you find because its’ value will be unknown, but if you can identify the part by its’ board identity someone may know what it is. Here’s a link to the service manual for your laptop. In it there are details on the pre-requisite steps and then the procedures to remove all the major components of the laptop. Assuming that you plugged the jack into an audio connector (or was it a USB connector?), if you go to the section dealing with the ODD and USB & Audio board at least you can follow the ribbon cable back to where it is connected to on the systemboard and start looking there first. It may be that replacing the systemboard is the easiest solution.
