Thinkpad T30 Sudden Getting Error 1802

2014-06-25, 0:01 AM

I have a Thinkpad T30 running XP.  Without having changed anything I have been getting Error 1802: unregistered miniPCI.

 

Can someone tell me why or what to do about it?

 

I did try to look for the "remove miniPCI movie" but the link did not show me a movie. or any other kind of picture.

Welcome to the forum!

 

There are two covers on the bottom of your laptop: one for RAM, one for the cards. Open it up, remove the wireless card and let us know what's written on it.

 

ThinkPads will throw the error in question when a "non-whitelisted" wireless card is installed.

 

There are ways of going about this. Google for "no-1802" hack.

 

Good luck.

Cheers,

George

The BIOS-battery seems to be empty. So it cannot keep the CMOS-settings anymore.

The previous owner probably has inserted a "non-FRU" wireless network adapter and set a CMOS flag, that the adapter got accepted by the BIOS.

 

See Error 1802 - "Unauthorized" MiniPCI network card

 

After replacing the CMOS-battery detach the WLAN adapter, set the CMOS flag again and insert the adapter.

Modifying the BIOS

Use no-1802 utility

OK, so I replaced the battery, and made a CD of the (unzipped) solution.

 

I then started my T30, carefully pointing it to start off the CD drive.

 

Same result - error.

 

BTW, my WAN is a whitelisted intel.

 

Any other advice?

Hi,

 

Mornsgrans hit the nail on the head with his answer above. But check the order of your steps. First, remove the WLAN card triggering the 1802-error. After replacing the CMOS battery, fix time and date settings in <F1>--->BIOS menu. Reboot and make sure time/date error does not persist. Then run the 1802-utility from CD drive to hack/fix flag in BIOS whitelist before installing WLAN card.

 

Edit: One more thing: I just read your post again and you say your WLAN card is already on the whitelist. What is the exact IBM FRU part number printed on the card? You may just have a bad wifi card. I have also seen bad/ dying CMOS battery or a temporary "CMOS glitch" cause 1802-error even with a whitelisted card. In such a case replacing the CMOS battery, and the wifi card if necessary, along with rebooting persistently should resolve the problem. One final action may be a power button reset: Unplug the AC adapter, remove main battery and hold down the power button for 30 seconds. Power up on AC power alone before installing main battery.

(Note in the original message, I did ask what could suddenly cause this error if nothing about the thinkpad had changed.)

 

The card is

INTEL WM3A2100  WM3A2100NADELL

 

Dell P/N: 09Y200

 

How would I tell if the card itself is bad?

 

For my part, I missed the part of the instructions that said I needed to remove the card before trying to restart it.
