Dell Latitude E7270 - Requesting BIOS clean/corrupt? service tag CB00KC2

[TripTop]

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 Windows with this BIOS but NIC driver doesnt seem to function in Windows and wifi card also not detected unsure whether this is due to bios image or unrelated.

I was going to write original bios back to see if this resolves both issues but decided it would be better ask for assistance on getting a cleaned bios.
and proceed from there...

If you have some free time and willing to assist i would greatly appreciate this.

Please see attached original bios

Hi hoaca388

Thanks for the quick response and file/bios,
i was able to write bios , dropped your file in me analyzer just to compare from original bios.

procedure i followed was : (using ch341a and cable with clip (clips dont always seem to connect 100%, and neoprogrammer 2.2.0.3)
(disconnected battery unsure if necessary)
read bios - saved it
cleared bios
write cleaned version to bios
read again, saved it and did fc /b on your cleaned and what was read and no differences.

2x powered up laptop , powers on turns off turn on
3th time it powered through dell logo and into windows
