Some background:
I have bunch of these laptops and some of them have a following issue; BIOS (and TPM) won't update and the laptop just restarts after trying (doesn't work from USB stick either).
Tried to copy BIOS from another machine but the laptop wont even start after (no power). Can someone explain why this doesn't work? The BIOS versions are identical.
In the attachment are two BIOS files from 2 different laptops. Version 1.30 works fine and was updated from earlier version. Version 1.24 wont update, and wont work if I use BIOS from another 1.30 laptop (or 1.24 for that matter). Service tags are in the folder names.
Please assist with bios
CDP80 LA-E151P
REV 1.0 A00
LATITUDE 5580
SERVICE TAG CF94FH2
ATTACHED BIOS
NO POST , JUST SCREEN BACKLIGHT. CLEAN ME PLEASE
I found this Service Tag in your file "5094JM2". Are you sure it's your original BIOS?
Your file isn't good, which SPI programmer do you use and do you a clip/clamp or de-solder the chip outside the motherboard?
What is your actual CPU because this laptop can be with H or U CPUs.
