Bluetooth daughter card on x41 Tablet

#1 Post by Sunshine701c » Sun Nov 15, 2020 2:14 am

I've got an x41 tablet that doesn't come with bluetooth by default. I took the bluetooth model out of an r50p that I had lying around (BMDC200) and it had the exact same shape and connector as the original modem card.
However, when I plug it in and turn on the machine, I get an error code about an "unauthorized daughter card" and won't let me boot without removing it. Is there any way to work around this? modded bios perhaps?

That BIOS should solve it.

IIRC the X41/t needs a BDMC3 (combo modem/BT).
Remove that BT-card, then try.
If error still there, also remove wifi-card and/or HDD/SSD, then try.

Unrelated: if you want faster wifi, get a TP-Link TL-WN861N (300 Mbps).
