DELL latitude 7390 bios dump

[hcx]

maybe clean me and bios region was not replaced

It appears that bios v1.39 does not work on this unit.

Thanks, your bin is working!
What was wrong with my fix?
I can read in the bios events that upgrade from v1.38 to v1.39 was successful. So what was wrong?

Hi, I'm trying to fix not working bios dump. What are the bits changed in Descriptor region:
0x131 6D -> 00
0x134 01 -> 00
0x202 F0 -> 40
?

How did you get MFS partition with OEM Configuration?

Hi,
Looks like theres another level of problem with this unit.
With this DUMP keyboard lights up fans are up, its restarting 5 times after 5 seconds (consuming from 0.100-0.300 A of current on lab PSU) each and then turns off and stays like that (consuming 0.032 A on lab PSU).
Probably a bigger hardware problem.

Thank you for your help anyway

Yes that will be high possibly that can cause this type of issues
