hi all, i got this notebook some times ago. synthom was notebook being completely dead. after some search for common problem, i see ite chip possible need programming, so i made some measurement and after see 0volt on power botton, i got a ite sio programmer, but was not able to see the chip by programmer. after that i ordered a new ite 8995 and this time when i plug power to notebook my programmer software see the ite chip and i started programming it, but after 40% all was almost dead. i try repeat the programming another time, but this time it stop at 20%. i tried another time and this time chip was not recognized annymore. so i inspected the motherboard and i see 3.3 and 5 volt chip getting hot.... i ordered a new rt8249c chip, and after solder it situation was the same ... rt8249c being hot. i inspected and found 3.3 rail shorted. after remove coil, if i inject 2 or 3 volt ... i see cpu getting hot....
cpu got broken? what's your opinion? how could that cpu go wrong without touching anything in the notebook ?
edit: after isolating the shorted pjp point on 3.3 rail, rt8249c get hot. im supposing that ite chip is the problem..... probably went wrong for no reason. ill try another chip next week.
