Hello awesome people!

LA-F322P rev 2.0(A01)
Service Tag: 558XHR2

I believe my BIOS is kind of corrupt, 1 out of 20 tries it boots, after changing RAM stick, RAM slot and disconnecting the battery for a while. The other 19 times, 2 amber lights and 5 white ones. BIOS battery is 3.2V.
My BIOS does NOT have password.

Can anyone check if it is indeed corrupt?
Thank you in advance.

Uploaded it but again seems bios was not the issue... I am still working on the laptop though as it is showing some signs of life...
Hoaca - thank you for your help, I have now eliminated the bios from my list of potential issues...
Thanks

[hehehh]

Thank you Hoaca - much appreciated! I will try it tonight and report back...

[hoaca388]

Thank you Hoaca388! I will try it shortly...

Can you also look at the second Bios when you have a moment? Below is the info on the second laptop and the dump.

ok, flashed it but sadly it did not help - it looks like the MB is bad on this one... I have higher hopes for the 2nd one.

Hello everyone,
I have 2 dell 7490 laptops that are not starting - when I press the power button the keyboard lights up but no sound, no display, etc. History unknown - i am cleaning up a closet and have these two identical laptops with same MB revisions.
I have tried the obvious - used known working memory, used ext display and keyboard, unplugged battery and CMOS battery, etc. to no effect. I am now trying to rule out the bios... My dump is attached - is there a way to tell whether the file is corrupt? Or alternatively, can someone modify a known unlocked bios from this thread that i can try on my machine?

here are the details of the laptop:
Dell 7490, ST=C393JM2
MB: DAZ40 LA322P rev 1.0(A00) 2017-09-21

your help is greatly appreciated!

- Missing TPM feature in BIOS
- Service TAG and Express Code changed different from before
