I received the programmer and flashed this BIOS file as is [URL]https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-laptops-tablets-and-mobile-devices/bios-requests-only/50493-e5-571g-a5wah-la-b991p?p=1007963#post1007963[/URL], laptop didn't post and I lost 3.3V in the U8's EN pin, but it responded to power ON button.

Then I tried with this BIOS file [URL]https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-laptops-tablets-and-mobile-devices/bios-requests-only/50493-e5-571g-a5wah-la-b991p?p=1457271#post1457271[/URL]...

I had in mind purchasing the BIOS programmer and, since I thought a corrupted BIOS could be an option for this laptop, I ordered it 4 days ago.It comes from aliexpress so it will take a week or two.
The BIOS I had in mind to test is the one from this post

Sorry for the double post but I can't edit the post above anymore and I forgot to add that I can't see capslock LED turning ON and OFF when the key is pressed, but I don't know if it has one, and the fan spins faster, slower and stops spinning depending on temperature. Also there's no display output through HDMI.

This might be it
6050A2137901-MB-A03.
It was under the wifi card, written on the motherboard, no sticker.
I think I found it online, some resistor values and names match.

Thanks for guiding me into finding the actual model number of the motherboard, I wouldn't have found it if it weren't for you....

Oh, thanks for the input.
There's a sticker on the cooler that says SPS: 6043B0034801. I'll have a look online too, maybe I find something with that code

Hi everyone, I'm trying to find the schematics or boardview for this laptop but I haven't been able to find anything yet. Looking at the motherboard number in Badcaps gives no results, and looking at the laptop model gives only AMD CPU results.
Laptop is an HP compaq 6735s with Intel CPU.
Motherboard is SPS: 456609-001, and sticker says Rev 3.30, but maybe the board is mostly the same for other revisions.

Hi everyone.
