Bluetooth OFF after restart / resume from sleep

Hi, i have problem with integrated Bluetooth in my T400s. If i start Windows from off state, BT is on and my BT mouse is connected correclty. But if i restart or go to sleep mode and back resume from sleep, BT stays OFF and i have to switch it on via Fn+F5. I tried to reinstall clean Windows 7 with all drivers through Lenovo System Update, but no solution. Does somebody have the same problem? Any idea?

Re: Bluetooth OFF after restart / resume from sleep

it's basically the same problem/cause as in my thread:

 

http://forums.lenovo.com/t5/Windows-7-Discussion/Win-7-x64-No-WWAN-after-resume-from-standby-and-Blu...

 

BT being switched off after resume was one of the symptoms, though my main problem was with WWAN

 

Can't tell you any reliable solution... but with you having that problem it seems that the WWAN problems are the side effects, not the other way around...

Re: Bluetooth OFF after restart / resume from sleep

Unbelivable, crazy things happens. You are right, problem is solved.

 

1 - 2 weeks ago i tried Ubuntu, not installed, just run from USB flash and look how new one looks like

2  - probably from that time integrated BT did not start after restart or resume from sleep - really strange (i have WWAn as well but i do not use it)

3 - i tried to disable  I/O Access for all devices in BIOS and set back On  - that did not help

4 - i have loaded default setting in BIOS by F9 and saved and after restart BINGO BT mobule works even after restart or after resume from Sleep.

 

It is really strange for me, but yeahh, crazy things happend.

 

Thanks.

Re: Bluetooth OFF after restart / resume from sleep

Why is this issue marked as solved when it does uncover a clear bug in Lenovo firmware?

 

Resetting the BIOS is just a workaround, one that people cannot use.

 

I can confirm the same issue on Lenovo t61p models, and yes it did happened after I booted Ubuntu one time.

 

Where we can report this issue and be notified when Lenovo team solve it for good?

Re: Bluetooth OFF after restart / resume from sleep

Hey my friend, be glad we have workaround. Do not expect Lenovo will solve such a small issue, if they do not solve really major bugs and issues :-)
