Re: Yoga 520 - battery drain while laptop is off!

Plugged the USB stick in the non-battery USB slot and an hour later the batter level was as it was left, so my tiny USB drive can stay in place without draining the battery.  I am sure you will have the same experiece with your mouse.  Thanks for the tip Smiley Happy ...the battery drain issue was very frustrating as I would use my Yoga for maybe an hour or two, then next day after being off for around 20hrs it would often need to be plugged into the mains just to power up.

Re: Yoga 520 - battery drain while laptop is off!

I'm also happy to report that after moving the dongle to the USB port on the other side of the laptop, problem is solved and there was no drain after almost a whole day of being shut down. Just in case, i also disabled the USB Always On option in the BIOS.
