Re: bios for hp PROBOOK 455 G8
Dear friends, i'm novice to forum, i can not exactly ask a question) ... I have an HP ProBook 455 G8 bricked after a failed BIOS flashing (under BIOS shell from wired connection). Do i understand correctly that DMI utility is no longer used in new models, and filling missing data in DMI is done in BIOS shell itself in MPM section? Is everything same as here? _https://www.youtube.com/watch?v=GuENOtU_B_w&t=264s
I still have a laptop warranty and i would like to know whether it is worth doing it myself (i have some experience).. ), or give it to service. Thanks for the answer.Comment

Hello,
I have a Asus ROG Strix Scar 15 (G533QM) that had a dead motherboard (Graphics card dead) and after trying to fix the motherboard with no success, I bit the bullet on a sale for a new motherboard. I ordered a motherboard for the 15 inch model which is the one that I have, and when the motherboard arrived it wasn't for a little while that I saw it was from the 17 inch model.
My question is, can I update the Bios on this G733 motherboard to a G533 Bios.
The reason for wanting to do this is that the keyboard isn't working as it should, and I think this... -
Need Clean BIOS/EC Bin File for Lenovo ThinkPad Yoga 11e - Stuck with 0275 Error CMS
Hello everyone,
I am attempting a repair on a Lenovo ThinkPad Yoga 11e that is currently stuck at boot with the error: "0275 error CMS" even after setup new bios battery and will not allow me to enter the BIOS/Setup.
This is a critical issue that I believe requires flashing the BIOS chip directly using a programmer (e.g., CH341A/RT809H), as standard software updates or resets are not possible.
I have opened the laptop and identified the main BIOS chip... -
hey all, i did a silly thing and flashed bios to perfectly working board. None of the asus official download bios would work with ez flash. They all gave error saying not supported bios file. I tried using uefi tool to extract it to a bin file but then ez flash wouldnt even recognise it.
So, i used freedos and afudos with the aforementioned bin file i extracted and forced the issue. After bios reprogram, reboot and it was dead. Fans spinning but no post.
i have a bios writer and none of the .cap files from the official site work either. I just get one spin, then off, then all fans...10-17-2024, 02:53 AM -
Hi there,
I have a 14" Lenovo Laptop (Flex 5 14ALC05) which has a boot issue.
The little LED on the power button is flashing slowly and nothing happen.
This unit do not have any BIOS button cell battery so I tried many times draining the power but it is still not powering on.
So I decided to flash the BIOS using a cheap programmer.
And I was successfully able to read the content (exactly 16MB file) which BTW is a WINBOND 74m12jwsiq (according to the package inscription - but detected as W25Q128FW in the software - IMSProg on Linux)
I also... -
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...
