Hi
i have dell latitude E7270 with following symptoms:
- takes long time to restart.
- sometimes powers on and then off
- sometimes while working it just dies,
From googling online bios clean could possible resolve this?
i was able to save bios and was going to try bios clean myself but get an below error when i drop it in ME analyzer.(unsure whether this sometimes occurs or could be due to bad/corrupt bios)
As ME analyzer gave me an error i just decided to write bios with a cleaned bios from E7270 bios post.
I reinstall... -
Laptop model: Thomson THN14B

PS: problem was partial short on PS7516 5V boost converter (near the 2R2 inductor) which causes symptoms that look like no POST problem....11-11-2024, 11:49 AM -
Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows

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...
