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:

My ibm thinkpad t43 displayed a message "hard error D0014" on a small blue screen. when i shut it down by pressing the power button for a few seconds, it restarted. but the programs won't work.


This could be a problem, not sure if its a software related or if the hard drive is bad. If you can find a windows xp cd. Try and wipe out the hard drive and install windows xp on it. If it goes thru then you'll just need the drivers. If it errors out on you then you know its a problem with the hard drive and you'll need to replace it. If you get windows xp installed on it, let me know and I'll help you with the drivers.

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

Network & Speed Problem


I suspect that the network interface card failed, & that's why you get the error message. Try disabling it from the BIOS & see if the error message disappears. If it did, then you have a failing network interface card & need to install anew one.

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
