X40 and 1802 error: Unauthorized network card is plugged in

2008-02-14, 3:22 AM
Hi,
I have an X40 with his original wifi card. After some bios upgrade, this error starting appearing:
1802: Unauthorized network card is plugged in - Power off and remove the miniPCI network card.

How can I solve this issue? Maybe downgrading the BIOS?

Many thanks
Oliver

The solution is fairly simple if you have a floppy or cd-burner. Read the instructions for the no-1802 hack

I checked the site but my BIOS and Type is not listed as working.
Is there an official way to solve this problem? I think it was an official BIOS that caused
the problem.

The notebook has never been opened, so it must be a BIOS error. At least the wifi miniPCI card
is malfunctioning

Thanks
Oliver

Using the Linux Life CD to apply no-1802, it should work on your X40.
It worked on this one: ThinkPad X40 2371-8EU 1.42 (2004/09/16; 1UET92WW) Windows XP Pro no-1802 Linux Live CD Yes
 
If you apply the hack, and later on you upgrade your BIOS, you have to apply the hack again.
All it does, is change 1 bit in the CMOS, which has no side effects anywhere else.

Many thanks, I think I can give it try only if that bit is always in the same memory address in all the BIOS.

I'm using the latest BIOS:
Type 2386-E9U X40

Bios version 2.08(1UETD3WW) 2006/12/25
http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-53881

Embeded controller 1UHTB2WW (1.62) 2006/06/01
http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-53882

Since the versions I have is a little more newer, that is my only concern

Like I said, apply that hack now.
If later on there is a newer BIOS and you want to (but you don't always have to) upgrade the BIOS, all you need to do is run that CD with no-1802 again.

This is ridiculous!
 
My X40 is original and I am getting this error message since today!! Unauthorized mini pci? Unauthorized by whom?!  Does this mean that they took this card of the authorized list? I think that this is an issue that IBM/Lenovo should fix and not have us go through some dangerous BIOS process that might screw up the computer.
Looking at the thread this has been going on for a while...without any solutions coming from Lenovo.  This is, for me, a BIG dent in my trust in Lenovo support.....will support continue to decrease since Lenovo took over?
