    Hey guys,

    If I order bluetooth with my t420 will it be a constant drain on battery or is their a shut off switch?

    thanks in advance!

    Fn + F5 lets you individually turn on / off the wireless devices.

    But can I boot it up without bluetooth on? And does leaving bluetooth as long as its not connecting to other BT devices waste battery? thanks!

    Once it is turned off, you have to turn it back on. So reboots do not turn it back on for you.

    I don't notice any difference leaving it on or turning it off when I'm not using it.
