Re: Hp 15 day11amb6e0
Es posible que estes usando un fuente para alimentar los +VA_AC, de ser así deberias usar un cargador original, que alimente AD_ID. En PL21 debes tener 3.3v y PL20 5V..Comment

Good Day,
Model : HP 15-p004nx
Boardcode : day11amb6e0
Issue :
When plug in, fan spins for a seconds then off,
When power on current responds up to 0.12A then back to 0A but no fan spin.
Checking the voltages, VCORE is missing checking enable signal, VRON also missing and already tried to flash bios and replace the SIO but same issue.
Another signal is also missing HWPG, i tried to look for the cause, I already tried cutting the lines coming from powergood signals of 1.05V , 1.35v ram supply and 5v supply ic but nothing change -
I found that 19v pins of flat cable was broken, so i connected with wire, but still nothing. cn2 pins1,2. Display now have 19v.
U2, L8 no stuff, so pin1 float. pin3=3.3v, pin4,5=3.3v
resistance on cn2, pin4=100k, pin5=82k, pin40=9k
Voltage not coming on cn2 pin40,4, before bios change.
My bios backup is attached...
