I have a ThinkPad R40-2723-58U. BIOS 1.33, Internal Embedded Controller 1.14, Windows XP Pro SPx.
Any external PCMCIA wireless cards work, but when I add the Intel® PRO/Wireless 2915ABG Network Internal Mini PCI Card, i get the error message, "Unauthorized Network Card detected..." and the computer does not boot. I have the latest versions of the BIOS, Embedded Controller etc for this model. What are my options to make this card work?
I looked at the specs for your unit and your systemboard will not handle that card. Even with the BIOS and EC updated, you will need to use a different card. If you have the FRU for that wireless card, I can look it up for you. Refer to the Lenovo support page below to look up all the FRU numbers for the wi-fi cards that are compatible with your unit.
