Re: HP Envy-15-as010ca black screen, No gpu voltage

I finally got the programmer, and re-flashed the bios (I took it from HP site)
but that did not change anything, still the same problem, still no enable signal to that "SIC631"ic.

What else can I do or check?

I guess, I could order that IC and replace it, but this just would be a guessing/replacing game.
Is it possible that one or more balls under the CPU/GPU got lose?
I still didn't find a schematic to find out from where is that enable signal coming from.

Thanks stingerchamp,


This is a standard bios chip "Winbond 25Q64FVSIQ"3V
The programmer will have "Auto sense" feature, I will pull it out to read/reprogram.

Thank You mcplslg123 for reply,

Ram stick is removable 8G DDR4 and it's fine (no difference with known good one).
I ordered new bios programmer (tl866II+), so I have to wait until I get it, once I do, I will post a reply what happened.

Thank You again!

Hello Everyone,
I have this HP Envy-15-as010ca laptop and I really need your help.
Short story is this: Laptop was working then I closed the lid and when I opened it again there was black screen, when I pressed power button the led blinked once and that was it, then I took it apart checked everything, all the voltages are o.k. except gpu voltage.
I did put a post asking for a schematic but I think nobody has it for this type of board, it is: Vanilla 6050A2821201-MB-A01.
It has "SIC631"IC for that voltage and there is pin#2=zcd_en# which is 0V and I don't know...

Thank You SMD Flea,
Indeed, I did download this file (twice) from post #4, but it is corrupted anyway, I used 7-zip (latest ver.), and WinRAR, and windows itself.
Can not be opened.

I downloaded this schematic: hp envy VANILLA 1-6050A2857201-MB-A01.rar
but it is corrupted, will not unzip/unrar.
