Dell precision 7560 bios and ec dump needed

[electronica]

Hi friends, I have a Dell Precision 7560 that came for unlock, so when I unlocked it, I put back the bios chip, but the laptop didn't come on. I realized that the chip is dead (gd25q256), so I replaced it with Winbond 25q256. Now the laptop come on with this error 6 white 3 amber
I tested many bios in this forum, but none worked. Same error: 3*6

Try this. Me clean file from your original bios. I don't think it helps, but maybe.

Press the power button for more than 25 seconds to reset RTC.

Disconnect all power sources (AC, battery, coin cell) and discharge any remaining power by pressing and holding the power button for 3 to 5 seconds to ensure all power has been discharged.

Thank you for your help. I programmed your bios, but the same problem.

Same thing, thank you.
Please, if someone has a clear HD picture around the bios area, maybe there is a missing resistance; unfortunately, a schematic and board view are not available.

Thank you; you're the best man.
My laptop has two issues: the BIOS chip and the BIOS file.
I used winbond 25q256 instead of GD 25R256, and they are not compatible.
So I found the exact BIOS chip and your dump, and the job is done.
Laptop come alive.
Thank you all for your help.
