Dell Latitude 5520 need bios for it

[The_Memory_Guy]

Hi, if this needs to go in different category please let me know

I have Dell Latitude 5520, however it refusing a Bios Update, the current Bios version 1.30. Its 11th gen with with an 1135 G7 CPU.

I have tried everything under the sun to try and get this Laptop to update the Bios, Latest version 1.47, however It wont do the Bios Update, via Windows, Via USB, Via Network, same issue, in Windows it does the checks and says its restarting the laptop, however all I get is black screen, nothing after that, 15/20/30 minutes, even 1 hour after.

I tried using the Bios recovery RCV file, after pressing CTRL+ESC and inserting the power, keyboard lights up and nothing, no Bios recovery Page. Just a black screen.

I tried version 1.36 (next one up) same thing

Checked all setting in Bios, should work, even deleted the Stored firmware updates in Windows.

Short of pulling the Motherboard out and removing and reprogramming the Bios with Fresh Bios, I am out of ideas. Can be done but its long.

Anyone experience a similar issue with Dell Laptop like this??? Let me know, could it be partition issue or windows issue or just a corrupt bios?

Kind Regards,

Hello all,

I have also problem with my Latitude 5520. Seems to be corrupted BIOS. Laptop turns on, fan is spinning, no picture (LCD Built-in Self-Test is OK), keyboard is lit, but thats all. Could clean BIOS fix this issue?

Service Tag: 66MX2B3
Motherbord model: I can't see the motherboard type from the inside.

It works for me, but there is one problem: when exiting safe mode, the machine can no longer power on. Can you help me?
