Question. currently using 5100AGN on T400.

Can T400 take any mini PCI upgrade - say 6200 AGN without bios issues ?

T400 (same as T500) will take: 1000, 5100, 5150, 5300 and 5350.
All other cards (despite Lenovo FRU) and with original bios will produce error 1802.

Upgrade T400 Wifi from 5100AGN to 6200AGN
