SOURCE: 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:
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
