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.

Re: vostro 3568 clear me
I have strange on this machine with likely BIOS problem. I reprogram above system turns on and no display with power LED blinking continiously. Consumes about 0.461amps, it looks like system is stuck on reprogramming something e.g. ME region.
Anybody encountered similiar problem, any ideas?
Thanks in advance.
