Hi, I'm quite new to this, I am trying to debug a faulty motherboard (DAY31AMB6C0). There was a fault in the DC input circuit with a faulty TVS diode after the first MOSFET shorting the VAD rail to ground. I was able to clear that fault by removing the diode and now the input section seems to be working correctly and I get the V3PCU power rail.

But trying to start the board still fails, I put some RAM in it and shorted the power button to start it up but it only blinks the power LED in the DC jack assembly 3 times. Maybe the AC detect circuit is broken? Or is this more likely to be...

Hello guys,

As per title says I have a Envy 15-Fh0500na , Ryzen 7, 16 Gb version.
Motherboard number is JPB51 LA-M798P rev.1.0
SN CND3421F16

The laptop is getting power when charger is connected, it charges as the light turns orange if battery is inserted, but it is not powering on. My first thought was that the keyboard was not working and tried to move the motherboard in a tested palmrest from a functional laptop with no success of getting it started.
I would like to try and write a new bios if anyone can help with a tested and working dump.

Update I did after all decided to buy a new business grade laptop computer from Best Buy they had a sale on this one and while I was there inquiring about this particular one so was another customer and the location that I was at they were completely out of
stock but another location had 9 of them in stock but by the time I got to the other location they only had 4 of them left in stock

The selling points are size of the hard drive and the amount of RAM it has for the price one other nice feature is the touch screen is nice because you can move the pointer where it needs to...

I honestly don't know what the problem could be. I know you can't fully diagnose a computer just by looking at a photo, but I don't see anything wrong with the laptop. The white ribbon connecting the battery pins to the motherboard was installed correctly, in my opinion. I'll try taking it apart again and reconnecting it again, but I honestly doubt it....

Here is the original BIOS dump, and after that, a few more BIOS dumps in the same file. I used the first one, and the laptop works, but there is an issue with booting into live Windows (I get an ACPI BIOS error). So maybe another one from that RAR or ZIP file would be a better match?

I will also include two original BIOS dumps in case one is corrupted, i think third_read is fine becouse of 8mb size.

The laptop has a touchscreen, if that is important.

Thanks for any help.​...

Hi guys,

I do have the same board in a Hp Envy 13-ay1013na, Ryzen 7 5800u
I only get the laptop to power for about 3-4 seconds with no caps code flashing, no fan spinning it just goes off.
My first guess was that is a bios related problem, as the laptop gets power, it does charge the battery.
Motherboard : la-j482p rev.1 SPS M76379-601.
I did try to flash the dump attached previously with no success and it dues the same thing.
Could someone check my bios or have a fresh one? thanks
