The No-1802 error when booting your IBM ThinkPad T30 alerts you that the Wi-Fi card in your machine isn't recognised. If your T30 BIOS dates from 2005 or earlier, you may have this problem. The simplest solution is to flash your BIOS with the 2006 BIOS version and follow that with the Embedded Controller Service update. Once those two updates have been installed, the No-1802 error should disappear from your machine.
