Re: Hp 15 with burnt mosfet

i just did a razor laptop with a burnt bad mosfet. it burnt so bad that the char was creating a resistance to ground, which had a plane right under the + rail. i pulled up and scraped away what i could untell the resistance went away on the + rail. unfortunately it also took away the traces to the battery monitoring chip which controlled the mosfets. i had to run a wire to them. i used a lifed trace and some wire to place a new mosfet.

4 contacts was good and no problem wire to other 4 contact so ic can be o its own place. way simpler and safer.
