Z61t error:1802 Unauthorized network card...

2008-08-26, 3:23 AM

 Z61T productID:9446W26

One month back I started getting above message. System board was changed to cure.

Today again, I got same error message, AT post above message comes, and thats it.

Burned all different kinds of cd's to try and boot and flash the bios, it does not go past POST.

 

for most recent scenario,I started getting above message after I bios upgrade to 2.25


(1) Is there a way to restore the old bios? atleast computer was working though without the wifi. 

(2) Is there a way to boot to DOS, windows whatever to cure this?

I have a T60 and just got the 1802 error the other day.  After losing 1.5 days of work, here's what I learned:

 

I've pulled the internal wifi card (3945) and then it boots fine.

 

(this was after I thought the pci controller on motherboard was dead & had the "IT Guys" come to same conclusion. (Day & 1/2 distraction pulling the HD & replicating my work environmental since I would be expecting a nice wait for a new machine).

 

Then, after noodling on the error, decided to find & pull the wifi card.  Booted fine.  

 

I think I could have toasted it from some accidential overheating.

 

Anyone have any suggestions on compatibility with replacement card (since I don't want to get the 1802 error went I replace it).

 

Best o' luck.  ABB

1802 Unauthorized network card...

2009-07-08, 13:29 PM

Any update on this subject?

 

It seems widespread among ThinkPads. My folks bought a Z61m, thought it came with wireless, found that it did not, bought an Intel 3945 card -- the same one Lenovo sells -- and when I installed it for them the 1802 error prevents the machine from booting.

 

I am familiar with the "NO-1802" CMOS modifying hack. It does not appear to work for the Z61m.

 

What are my options? And why in the world is the Intel card IBM sells seen as unauthorized?

Welcome to the forum, jwoold!

 

No, the hack doesn't work on T43 and later models. You need an Intel card with a FRU number, for a list of applicable cards check this page under # 6:

Hope this helps.

the wifi card was burned up, probably from multiple overheats on the unit.  It was still (barely) under extended warranty & got replaced.  new replacement card worked fine. 

 

alternatively, could have picked up a PCI card for much less invested time.

 

overheat was issue with that machine.  no so much with T500, altho its had its share of buggies & BSODs.

 

cheers.
