1802 Unauthorized network card after bios update

2014-03-19, 16:13 PM

I have a t430u model 3351 that is 13 months old.  I updated all the drivers through the Lenovo system update, the last thing to update was the BIOS.  The BIOS successfully updated to version 2.08 and everthing was fine.  Then I had to reboot the computer due to some windows updates, upon turning back on I get the 1802 Unauthorized network card is plugged in.

 

I never replaced the network card, it is the original card so I think the BIOS update is causing the problem.  I pulled the network card and the FRU P/N on the card is 04W3763.  With the card out it boots up again but I can't believe the card is the issue since it's the original part in a 13 month old machine.

 

Not sure what to do, I'm hoping there is a way to roll back the BIOS maybe.

 

Any suggestions appreciated.

Finally got my part today, it's a 60Y3247, which was listed on the whitelist along with my original 04W3763. Popped it in and it works. It's probably a downgrade since the 04W3763 had bluetooth. So I have been without my laptop for a week and I'm out 5 bucks.

Glad I posted, but unfortunately I don't think this will help anyone in the future.

It won't prevent someone from upgrading the BIOS since they wouldn't check the forums until after the BIOS breaks their machine, and buying a new part is really not a solution.

Good afternoon and welcome to the community.

 

A question... Did you purchase the machine new, direct from Lenovo, or used from a 3rd party?

 

Regards.

 

Edit to follow-up: Looking at the FRU BOM for the T430U:

http://download.lenovo.com/parts/ThinkPad/t430u_fru_bom_20130822.pdf

you'll see the section for wireless adapters. There are three for WLAN, one Intel, and as best I can determine, two RealTek. Your FRU, which again as best I can tell, is a Broadcom, isn't on the list. That would be a reason for your 1802 error hitting the BIOS whitelist.

 

So, if you got the machine from a 3rd party, what likely happened is that they swapped in the non-whitelisted card and applied a modified BIOS to make it all work. Once you updated with the official BIOS, you essentially reapplied the whitelist and the boot fails with 1802.

Well, that's a stumper.

I've not heard of a situation where applying a BIOS update to an "authorized" factory configuration has resulted in the original factory-supplied wireless card hitting the 1802 wall. If you're still under warranty, I'd consider contacting Service about this.

 

If you want to explore back-leveling the BIOS, you can find links to two prior versions near the bottom of the following page: http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS031725

 

Regards.

I just called and since it's 1 month out of warranty they won't help and suggested I check the forums. Thanks, I'll see if I can follow the back-leveling instructions.

I tried 2.02, 2.06 and 2.08 but it won't let you downgrade the BIOS. It reads the BIOS and says an update is not necessary and there are no other options but to reboot.

Do you see an option to allow back-leveling in your current BIOS?

Updating BIOS via Windows application always had issues. It is better to use bootable CD image edition.

 

On the other hand there is a risk with every BIOS update that it might fail and your motherboard is dead. Have you tried to load default BIOS values ?

I have flash BIOS updating by end user ENABLED
Secure rollback prevention DISABLED

I can boot to ISO disk, but when I try to run the
Update system program I get an error
Error: The system program file is not correct for this system.

I get this with both the 2.02 and 2.06 disks. Then if I try the 2.08 disk I get:
An update is not necessary at this time. The process has been cancelled.

Are there any other BIOS settings I need to modify in order to roll back?
