T410 Bluetooth radio powered off after standby must be manually activated with Fn+F5

I've just received a new TP T410 2522-AT6 with XP SP3 and I've noticed that the bluetooth radio is not automatically powered back on when resuming from standby or after a system power off/power on (as wireless radio correctly does).

With my previous thinkpads (T42 and T60) the wireless and bluetooth radios where both brought back on if they were on before standby or power off (as it should be imho).

This behavior is pretty annoying because I use the bluetooth connection to automatically keep in sync my Lotus Notes calendar with my nokia phone with an automatic refresh every hour (Nokia PC suite feature), but in this situation, if I resume the T410  from a standby (or power off)  I must remember to manually power the BT radio back on or the connection is broken.

I've checked everywhere (power settings, Access connections settings, BIOS, BT configurations) but I didn't find a place to change this behavior.

As a workaround during reboots, I've put a batch program in my XP startup folder that uses  ACFNF5.EXE (access connection program) with the /bton option, and this seems to work... but I'm still stuck when going in standby!

Any ideas on how to fix this? Anyone knows a good reason for this changed behavior?

Thanks

This happend on laptops, on which you tried some linux OS like liveCD of Ubuntu, or something like this. The solution was to reset BIOS. Then this problem disappeared. Do not know, if this is your case, but anyway you can try to reset BIOS.

Thanks, that's what I did (bios reset to default setting).

But, weird thing, the first reboot after bios reset didn't fix (went to standby with BT on and when it woke up BT was off again).

Did a desperate move and disabled the BT LAN object in the Network Configuration folder and, voilà, standby and reboot where finally leaving the BT radio on when restarting.

Weirder thing, I re-enabled the BT LAN and, unexpectedly,  the BT radio behavior was still good...

Anyway, I'm glad I finally made it, thanks again for your help!
