hello
i have an asus ux303ub to repair
no sign of life : no leds, no power, no fan.
initialy, only 10V on board nothing else, nothing hot
after cleanin and discharge bios battery : i have 19v; 3,3v, 5v
but no led, no power , no sign of life at all
when i plug in at this moment, i have a smoke at uP0132p, with a burn point at the middle of the chip
with that, short to ground on VDD_IO on a chip near usb port : CX20752 (0,005 with diode mode) and 0,013 at coil near rams.
with measure voltages : only 0,236V at coil for battery and 0v at all other coils.
i removed up0132p and i have same measures.
if i inpout amps on the line that are low (of course no inpout for low resistance lines near cpu (0,015 for example at diode mode), nothing went hot
when i resolder up0132p, it becomes hot only.
if i measure resistance around this chip, nothin at low resistance but the jp8302 point wich is 0,007 with or without the chip.
can someone help me ?
thank you guys
