If you have a Yoga 3 pro and your battery is not charging here’s a silly easy fix that you may try! without opening up your computer!
1 – Turn your computer completely off and flip it upside down
2 – Use the image bellow and pinpoint the location of the Battery connection cable (the cable in the top center of the battery)
you can do so by coordinating with the edge screws and the center of the computer.
3 – Place the computer on a flat surface, and gently but firmly press on top of that cable (through the plastic cover) several times, (as if you’re doing a point massage).
4 – Turn on the computer and enjoy your battery again!
Conclusion: this issue happens more often than you can think, usually because Lenovo’s Battery clip is a bit loose and comes off either by itself (because the factory didn’t tape it)
or due to a light nudge or a drop.
This case is isolated to Yoga 3 pro computers only
All other versions of Yoga do not seem to be sharing the same silly cause!
