Acer TMP259-MB-70RA
dazaamb16e0

no power
charging
3v ok
5v ok

pl15 shorted to ground +1v_s5

wheh i press power, consumes 0.456a

processor hot, the rectangular chip not the square one,i think its the intel uhd, its it possible to cut +1v_s5 going to processor.

Re: Acer TMP259-MB-70RA processor heat

In ohms value?

PL15 will always be short to ground as low ohms
456ma is ok with press

Re: Acer TMP259-MB-70RA processor heat

0.2 ohm is very low, I hope you checked in ohm or continuity range

It proves indeed short, if you have schematic check supply is connected to which parts

It seems core voltage or vccsa supply

when i press power,processor right side will get hot, and still no gpu,cpu,ram supply only 3.3v and 5v, bcuz +1v_s5 is short. hmmm

With schematic check power sequence
