So maybe this is the right place to post this? Anyways, my brother asked me to look at his laptop after it had been out of commission for a while now. Upon opening it up and realizing it got super hot in one area near the CPU, i noticed it was clearly burnt/fried from what looked to be some sort of short circuit. The label for the component is 'PQG1" and there is an identical part labeled "PQG2". I kinda just want to know what it stands for and what it actually is. Tried searching around google with no luck so thought id just try here. Thanks in advance with any help.
