Hi, I have a hp probook 450 g5 i5 8th.
Initially when I plugged in the power the notebook turns on by itself and after a few seconds the fan, I noticed that the kbc nuvoton was overheating and I ordered a new one from china.
now after changing the new kbc, when I plug it in the screen flashes and when I flash various bios it almost always changes behavior.
Important thing, when I plug in the power, the blue light appears for a second and then goes off, the battery is charged.
I attach my original dump to cleanComment

it's all soldered well, go over them one by one.
I bought the chip on aliexpress asking to program it for the card in question.
Has the chip been reprogrammed? or if it reprograms itself with the 16mb bios file
There is a difference between one chip and another, with the old one I tried to reprogram some bios but it didn't do anything, only the fan at maximum, this one instead tries to start.Comment

So, I tried to put a VGA cable but nothing, then out of curiosity I put a USB stick and the result is excellent, it started with errors though, is it possible to clean the bios file? so that I load my original?Comment

I'm requesting a bios .bin for 2 of my hp Probook 450 G3's. Both of which I had forgotten the bios passwords. I stupidly flashed both of them with firmware "made" by the RCUnlocker software and I guess I shouldn't have. The last thing I did was flash both of them with RCUnlocker-fw thinking it would 100% work and left my programmer etc behind and won't have access to them for another 2 days so I figured I'd create a thread to see if I'd be so lucky that someone might have a working file laying around 😝

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,... -
Hello,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....
