I was searching the BIOS on this Alienware Area-51m laptop to try to find the info for a customer, but could not find it. I discovered that info is encrypted and hidden only Dell can pull it up. So then I thought, there may be someone who needs a working BIOS dump bin file for that laptop. So, I am uploading it to help others who may need this to unbrick the laptop or fix their Area-51m. The BIOS chip was a Winbond 25Q80DVSIG. If this helps someone out there, then my labor was not wasted.
I just zipped it so I could attach it....

Hello everyone,
I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.
When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.

Hello.
I'm wondering how can I check and extract de dmi area from a bios backup.
I know it depends on the brand and model of the motherboard. Is there some guide that could help me understand and extract the dmi from the original bios dump to a new bios file.
The motherboard is H510M-HDV/M.2 SE
Attached is:
h510m is the dump bios
h510mhms1 is the downloaded bios from the website...10-09-2025, 02:23 PM -
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...
