Da0g7dmb8d0 ec&bios

[Spider1211]

Hey guys, can someone please provide known good BIOS and EC for the following:

Model: HP 13-an0002nf
Board: DA0G7DMB8D0 REV

Device came is with flashing caps lock (3 long and 2 short). Upon disassembly, it is very obvious someone else previously worked on the BIOS chip.

I am not sure if the dump is any good since its showing as "configured" in ME analyzer instead of "Initialized" or maybe whoever worked on it before cleaned it. I tried cleaning ME nonetheless but no change.

All voltages present except Vcore. I already checked for shorts and everything looks OK.

Please find attached dumped BIOS.

look a slot and change Ram.

Re: Da0g7dmb8d0 ec&bios

Its onboard RAM, not slot (not even present). Tried to reflow RAM chips but no luck. As per HP, 3 long & 2 short blinks is: "The embedded controller times out waiting for BIOS to return from memory initialization.".

I'ld like to eliminate possible BIOS or EC issue before blaming the RAM chips.

if a have a black pads same error in rams or slot. now are dead, try.

Re: Da0g7dmb8d0 ec&bios

I did not understand, can you rephrase please. What do you by black pads? Do you mean the RAM chips (or some of them) are dead?

Thanks you for the file, but no change unfortunately. Still same flash sequence.

Your original backup is from a HP 13-AN0020TU (same bios as the 13-an0002nf) ,it has some corruption,and because its still configured and not initialised would mean the board never posted far enough to read the bios chip properly because of the corruption,or for some other reason. Try another chip and the attached bios.

Re: Da0g7dmb8d0 ec&bios

Thank you @SMDFlea but no change unfortunately, still same issue.

Edit:
Forgot to mention but with all BIOS I tried, screen can be seen to darken when power button is pressed.
