Question 1

Driver install fails?

Accepted Answer

T43 packages are often 32-bit Windows XP/2000 only. Confirm OS bitness and the 2669W5B package; run as administrator, and install the Intel chipset driver before audio, wireless, or ATI Mobility Radeon X300 drivers.

Question 2

Device not detected?

Accepted Answer

check BIOS for enabled Ethernet/wireless/Bluetooth, turn on the ThinkPad wireless switch, and install ThinkPad Hotkey/Power Management so Fn controls expose devices correctly.

Question 3

Version conflicts?

Accepted Answer

generic Intel/ATI or newer Lenovo drivers can conflict with IBM ThinkVantage packages. Remove the old driver in Device Manager with “Delete driver software,” reboot, then install the matching IBM driver; avoid mixing System Update and manual versions.
