New X1 Carbon touch 20A7 bluetooth issues (Lag and disconnecting and maybe more)

Hello all,

I recently received my new X1 carbon touch and am satisfied with most of it and the capabilities it has. 

At office, I connect my laptop to a larger screen and bluetooth keyboard and mouse for better control and better work experience. I use Logitech laser MX that I have since long time ago, at home I use a smaller logitech bluetooth mouse as well.

I'm experiencing lags, after using the mouse (and keyboard) for few seconds, If I give it few seocnds I can work again for a minute or two, but for the long run it's really inconvenient. Sometimes the mouse will disconnect after couple of minutes and will not return to work until the computer will sleep and wake up again. 

I do not like to spend a free USB port for another keyboard since there are only 2 now.

Please help!

Ilan

Hi Llan,

 

Welcome to Lenovo Community Forums!

 

I’m sorry to hear that Bluetooth in your Lenovo ThinkPad X1 carbon is frequently getting disconnected.

 

Try unchecking "Allowing the computer to turn off this device to save power" in Device Manager->Bluetooth Radios->ThinkPad Bluetooth 2.1 with Enhanced Data Rate->Properties->Power Management.

 

Try checking with replacing the new battery in the keyboard and mouse.

 

Hope this helps!

 

Best regards,

Hemanth Kumar.

I've got the exact same problem with my new X1 Carbon Touch 20A7. Bluetooth lags, disconnections....

 

Changing the power management setting didn't change anything.

 

Windows and Drivers are up to date.... I'm currently using a Bluetooth USB dongle... which is amazing for a laptop of that price.

Hi Leveilleur,

 

Welcome to Lenovo Community Forums!

 

Could you try reinstalling the Bluetooth drivers?

 

If you have any difficulty in finding the drivers, please share the MTM number of your device so that I can assist you with the drivers.

 

Hope this helps!

I unsinstalled the driver, reboot, reinstall it, but the version number doesn't match with the one on the link you gave me.

 

I'm running Windows 8.1 Update 1.

 

Thx

Christopher
