For ibm thinkpad t41,Error 1802 unauthorized Network card is plugged in - power off and remove the miniPCI network card


You may have installed the wrong driver.
Go to System Restore and restore the T41 to a date before you installed the Network card driver.
Then go to the Thinkpad/Lenovo WEB site to download the Network drivers for the T41.

The same model ThinkPadcan have different types of network, video and audio drivers and unless youknow exactly which one is installed in your ThinkPad, you need to download allthe drivers and install each driver until you find the right driver. When you download thedrivers, write down the device driver and it's file name so you have a recordof which driver you are installing and which directory the unzipped files arelocated on your hard drive. Go to the IBM/Lenovo WEBsite - support/download page and download the latest Windows device drivers foryour model computer, Use this link: - http://www-307.ibm.com/pc/support/site.wss/product.do?template=%2Fproductselection%2Flandingpages%2FbrowseByProductLandingPage.vm&sitestyle=lenovo&brandind=10&validate=true You can download thevarious drivers and then you click on and run the various driver files, theywill then unzip and expand into a sub folder on C:\drivers Then install thevarious drivers from this folder (run the set-up file).

How do I fix a 1802 code - unauthirized network card is plugged in - power off and remove minipci newtork card and will this affect my wireless internet connection? Thanks


Hi,

Yes it will affect your wireless connection as the computer see's the hardware as unauthorized.

To fix this problem you will need the latest bios update from IBM's support website or go into the BIOS by hitting F1 when you see the IBM logo. Once in the BIOS set it to defaults, save the changes and exit the BIOS, see if that helps.


Good luck and regards.

1802; error when i start thinpad t40


Sounds like a non-IBM network card is installed. Remove the card and reboot your laptop.

System will not boot up.


Thinkpads have readable "FRU" (Field Replaceable Unit) numbers storedon various components, and at boot up time, for those internal devices(fortunately excluding drive, memory, etc) if they do not "respondcorrectly" saying they are a valid IBM part, they will give this 1802error.

It could be that the referenced device has failed, and thus seems to be there but not responding; it could need reseating;

The Lenovo site should be able to help you with a service guide to remove the card and see if that works.

there is also a "hack" to change the bios of machine - I think "prior to T43" to delete the 1802 check:
http://www.command-tab.com/2006/02/26/thinkpad-1802-error-fix/

Be aware any "hack" can disable the machine completely!

If it does turn out to be the mini PCI network card, you can tryremoving it and going with USB (did 600s' HAVE usb? I can't remembermine any more) or try to find a "genuine" IBM replacement on eBay orITxchange.com

IBM R40 2722 1802 Error Message


This is due to the fact that IBM laptops have a list of accepted devices, and the pci card is not recognised in the list. On IBM - Amilo, Mini PCI card slot is usually at the back of computer. Locate and remove Mini PCI wireless card, you will not have integrated wireless after this.
Other solution is to find the option to disable mini PCI in bios settings.
Here is how mini pci wireless card looks like:

Error Message on boot


Hi,
IBM requires using a "branded" network adapter, meaning one that has IBM's name on it, no matter if it's broadcom,etc. There is a couple of workarounds for this problem which would enable you to use whatever wireless adapter you wish. I would google IBM R40, and error 1802 and you'll find the application you need. Unfortunately, I'm not able to offer it to you here.
Good luck
