Re: hp 15-bs031ne BIOS
Yes you can program it with the RT809F. Search google for "RT809F kb9012" ,you`ll find plenty of videos showing how to solder the wires to the adapter,and keyboard connector pins.There`s no schematic available for this motherboard.

Just had a customer bring in a HP 14s-fq1010nm to do some maintenance.
After updating the BIOS to the latest (F.35) I get black screen (no backlight turning on). However the backlight turns on if I connect an external display to HDMI, but when booting to Windows, both displays remain black.
After disconnecting internal LCD, and plugging in external display via HDMI, it works on external.
I tried downgrading it using official method - using an USB drive with older BIOS version, but it fails, saying that the BIOS files are corrupted. I used about 5 different older BIOS versions... -
So I couldn't remember my bios password and since it was broken screen, I used to connected to the TV via Type C to HDMI. So I decided to remove the Bios chip and reprogram the Bios chip with ch314a.. when I try to solder Bios on the laptop, one of the Bios leg broke off.. I bought a new blank Bios chip so I can programmed by flashing on the bios. -

Power button works okay....power light goes on
Red "bottom" leds go on
Charging led works
Fans do not spin, capslock key does nothing, screen stays black
I would like to program the bios again, to rule out a corrupted bios.
However I run into a size error

Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble... -
Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...
