Re: "Genuine Battery not attached" on yoga 13

hi Takah,


Since you're still under warranty, did you sent the unit for service to replace the battery?


Have you tried to:

1. Uninstall the Lenovo Energy Management in Control Panel (large icon view) > Programs and Features and reboot

2. Re-install the Lenovo Energy Management software below and reboot


Lenovo Energy Management for 64-bit Windows



Let me know your findings,

I have had that problem a couple of times.

I ran the computer until the battery completely died and the problem went away when I plugged it back in.

Re: "Genuine Battery not attached" on yoga 13

I had a client bring in a Yoga 13 with the same problem: Plugged in, but not charging and "Unauthorized battery" message, even though it was the original battery that shipped in the computer.


Tried uninstall/reinstall Energy Management to no avail.


What worked was to follow the Service Manual to the point of disconnecting the battery pack, let it sit for a few minutes, reconnected, reassembled and it is now charging again and shows genuine battery.

And we're back...

Move delayed but still coming
