Try first this bios file , rebuild from your original dump.
If it's not working then try the second file which has a clean ME region.
Please provide feedback....Last edited by Stefan Steff; 08-04-2025, 10:53 AM.Leave a comment:

That dumps worked for me on several 840 G5 laptops.
First , you must check all components near the EC and BIOS chips to ensure you have not blow out any little resistor and second sometimes it takes a long time to boot for the first time after flashing both EC and BIOS and I mean even up to 5-10 minutes with several restarts.

Your provided serial does not match any of the dumps provided...in fact the two dumps are from different laptops...anyways,
here you got two dumps (EC+BIOS) but you need to use BCU tool to enter factory data ... from your provided bios content is this:
Description: HP EliteBook 840 G5
Serial Number: 5CG8180LLR
Product Number: 2FA66AV
Board CT Number: PGWHT00WBAR2GG
BuildId(BID): 17WWCSAT601#SABH#DABH

Keep the original content safe and write this patched content.
Should boot and follow the procedure described on the first page of this topic.
If all going to be ok then write back your original bios content.
Good Luck!...Leave a comment:

OK, I have another build prepared for you and if this isn't working for you the maybe some other forum member will help you out.
If a build isn't working always write back the original to assure you didn't blow away a component or you don't pick up by mistake a component with the soldering iron...
Good Luck!...Leave a comment:

Yes, danro can upgrade to AX200NGW no mater what...there is no Lenovo/HP approved AX200NGW.
AX200NGW has an Vid/Pid ( Vendor ID/Part ID) 8086:2723 which is in the whitelist of Lenovo M920x BIOS....Last edited by Stefan Steff; 07-20-2025, 10:53 AM.Leave a comment:

Your problem is not whitelisting...when there is an incompatibility problem then the laptop starts OK but the booting process is halted with a message like 1802: Unauthorized network card is plugged in...
The Interface Type of the two cards are different:
I extracted from your bios file all types of compatible WiFi cards and adapters, so here is the list pick one :
Centrino Wireless-N 105
Centrino Advanced-N 6235
Centrino Wireless-N 2230
Centrino Advanced-N 6205 [Taylor Peak]
Wireless 7260
Wireless 3160
Dual Band Wireless-AC...Leave a comment:
