HP Omen 17-ck0010nl no video

[DoOm86]

Hello,
I have the following notebook:
HP Omen 17-ck0010nl
SN: 5CD2018YV7
MAINBOARD: DA0G3LMBCG0 REV G
BIOS CHIP: WINBOND 25Q80DV16 2139 6124 52200

The computer stop posting while whatching youtube. It turns on, stay on, it charghes the battery and turns off if i push the power button. I have all the necessary rails present, no shorts were found. Already disconnected everything from the mainboard and change the ram (trying even one per time in both slots).
At this point i believe is a bios problem. I try with an usb pendrive and the bios on the HP site but it doens't work (i knew it but i still tried).
I'm not expert of bios, i know since it's an intel i can't just flash the HP BIOS from the site into the bios chip. I'm about to make a reading of my current Bios and i'll save it, if needed i can upload it here.
What shoud i do?

Post the original bios of the laptop even if it is corrupted...

[DoOm86]

Ok, I couldn't read the chip with the clip that comes with the ch341. Tomorrow morning or Monday I'll desolder it and solder it on the adaptor. I hope the cheap reader won't give me hard time. Then I'll post it here.
Maybe it's the ME region 🤷

[SMDFlea]

The 25Q80DV16 is not the bios chip

[DoOm86]

SMDFlea It's a winbond, it's start with the number of 25 and has 3,2v. But maybe you are right. I just checked the datasheet and take a screenshot. I'll check the mb better asap, probably i got tricked 🤦🏻

Find which chip has the number 128 on it, for example: 25Q128DV.

[DoOm86]

OK, i found it. it's a "mxic 25u1633f".
It doesn't have "128" in it but it is the only chip that according to the datashhet is a bios chip.
This notebook has also another chip close to the SIO (IT5570e-256 CXA) which is still a ITE (8308fn CXA). Never seen something like this.
I backuped the bios (hoping is this one mxic 25u1633f😆) and posted it here

red square

[DoOm86]

volinakis The chip in the red square is the pic with the ic "mxic mx 77L12850F" . I took some other pics of ic on the board.
The ic "mxic 25u1633f" that I upload the bin file previously it was close to the cpu, under the black plastic tape.
Don't tell me I backed up the wotng bios 😅 according to the datasheet the "mxic 25u1633f" is a bios ic. The "mxic mx 77L12850F" in the red square doesn't have the "25" or "24" at the beginning like the usual bios chip has.
Obviously there are many things I don't know about ic bios 😅
Anyway if the "mxic mx 77L12850F" is the bios chip, tomorrow I can upload here the bin file.
Thanks 🙏🏻

not "if", THAT'S bios chipset.

[DoOm86]

Ok, tomorrow I'll try to back it up and post it here, hoping my cheap bios programmer will do the job (ch341).
Thanks for the help till now, I really appreciate it

use AsProgrammer as software for CH341A

[DoOm86]

I succeded to save the bios with the AsProgrammer. i lefted the setting as they were (size=16777216; Page=256; SPI=25xx).
Thanks in advance guys

try

[DoOm86]

Same thing. It turns on, stay on, it charghes the battery and turns off if i push the power button. I have all the necessary rails present, no shorts were found. The display is completly dark (no image, no backlight) and nothing with an external monitor. I cecked again the pin of the bios with the oscilloscope and i have both voltages and signal presents.
Can we try a different bin or we are sure that is not the problem at this point?
Thx

that's the only one extracted from bios update.

[DoOm86]

OK then. I'll try to check the entire board again and see what i can do more to try to understand what the problem could be. i'll write here when i have updates

[DoOm86]

Update: after making many many attempts and checked everything, I belive the GPU has failed (but not shorted). I sent the laptop to HP which replace the mainboard. Now it's working perfectly. I checked the values of the new mainboard and confronted them with the old one. On the GPU coil the ohms value was higher on the new motherboard, that's all.
Hope this can help someone else in the future.
Thanks everyone for the help.
