标题: hp g62-a32ee dead

Today I am sharing hp g62-a32ee { foxconn pm_i_hpc_s mv_mb_v3 } no power issue…

Attached psu its take 0.002 amps when u swithed on its take0.024 amps and off no lights blinking..

Then check 3v pcu its came 3.3v and check 5v pcu its 0v butwhen u switched on its came 5v and within second its 0v

In this kind of problem I always check on i/o chip acav _in[here is acpres] its always high but here its low.

So check dcin on max8731 its came 19v

then check max8731 LDOits 0v

That’s a problem LDO not come that means its max 8731 isfaulty

Just replace max8731 and fix the problem…..thanks..

now check on ldo its 5v and acav _in [here is acpres] its also came 3,3v

and also check load on power supply unit its a 0.024 and adptor in indicator light is blinking...

这是个褒意吧

意思是从小没学好，但长大了还会修电脑，说明你天资不错。
