HP-Envy15 15-as133cl schematics and BV request

[kroman]

Hello, I am looking for schematics or board view for HP-Envy15 15-as133cl, Board: Vanilla1-6050a2857201-mb-a01

Fans spin but no POST, no image out from hdmi or known good display. cmos battery is good, tried clearing cmos, tried known good ram in both slots alternating, tried multiple key booting combinations, draining all power, booting with known good battery and known good chargers combined and independently.

Friend says she left it on her desk watching youtube shows to bed, woke up with laptop not turning on.

history: battery replaced once, one ram stick was removed before when it became bad, came in twice with no booting which at the time issue was fixed with clearing cmos.

I have used search features here and in google and I haven't found exact schematics, one example is "HP Envy 15 (Quanta SP7).pdf" can be found on google but not sure if thats the one I need.

Any help with those files would be greatly appreciated!


Should be worth noting: i have the ssd with me and I can boot it on another PC and I can get windows event log files of right before it died

Hi. Good afternoon.
I have the same laptop on my desk with the same issue reported by you.
I've tried all the options that you mentioned above.
The only difference is that when it came in CPU had no voltage and fan on high speed.
After replacing RAM the CPU started to get voltage and the fan went to low speed, but still no display.

Have you fixed the issue with your laptop?

Thanks

Hello, No I have not fixed the issue I still have the board with me. No obvious shorts heating up.

I put it aside for now but I can take voltage readings if you would like to compare with.

Hi, I know the post is old but these boards give a problem in the integrated circuits intersil 95859 you test voltage outputs in CPU coils
