I suspect your machine is freezing at some point. Pull out HDD, Keyboard, DVD and try again.Leave a comment:

Finally it worked.
Earilier I already flashed each and every dumps via SVOD3 but it didn't work. Even this dump. And today I flashed with RT809F, it worked. Don't know logic behind this, maybe SOVD3 error in my case....Leave a comment:

Re: LA-C501P No ACDRV??
Thanks for reply, both ACFET and RBFET is +0.500 on diode mode source to drain only. Didn't understand CLR but ACN and ACP continuity is ok.
VCC=19v
ACDET=2.6v
REGN=6.0v
ACOK is missing.
Plz note: I fixed hp machine where ACFET wasn't ok, fixed with replacement. Now same issue on NM-B241....Last edited by dspok; 08-04-2022, 08:57 PM.Leave a comment:
