Hi, I have been struggling to follow instructions to fix my BIOS through the guides here and hoped someone can help. I have made a backup of my BIOS but cannot merge with a newly downloaded BIOS update from Dell. I have tried to follow the steps but I keep failing. Any help would be a greatly appreciated. Thanks

Re: Vostro 5620 BIOS
Ok. I have tried again and realised that when I try to detect chip it says no chip found. The backup I thought I had made is useless.... The chip is XMC 25QH256CXIQ and the programmer is CH341A Pro with WSON8 adaptor. Thanks again for your help and patience.
For some background... The laptop is believed to have been powered off during BIOS update and now wont power up.Last edited by bcrsr; 06-16-2023, 09:03 AM.Comment

Hello,
Computer Model: Dell Vostro 5620
Service Tag: 4HPNGS3
Reg Model: P117F
Problem: Computer appears to try to power on, but doesn't complete POST and doesn't charge normally. This machine might have several problems, but I wanted to start with a new BIOS.
I created a dump of the original BIOS which is on a GigaDevice 25B256EYIG WSON8 IC and then I downloaded the latest update from Dell and used Dell PFS python script to extract out all of the images but this is where I am not sure what to do. I know I need to merge in the BIOS update image into my dumped file and maybe even clean the ME but I am still not used to doing this yet so I was hoping someone could help.
Thank you. Attached original dump.Comment

Dell Vostro 5620
Service Tag D47CKL3
System powering on but not posting image, PCH side of CPU is working and cycling thru some amperage around 0.15-0.30 but CPU side is not working and no voltage at coils at all.
I suspect this is a BIOS related issue
Any help will be appreciated

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.... -
Hi everyone,
I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.
I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.
After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.
I have desoldered the bios chip (GigaDevice...
