Yoga 13 Charging not working?

2012-12-12, 13:24 PM

I take my Yoga to work everyday and at night it is on AC power while I am asleep for at least 6 hours. Recently I have noticed when I get to work the battery indicates it is only around 58% charged.


1. When I got to bed I simply close the cover and I don't reopen it until I get to work, I am assuming it is going into sleep mode, and at the very least even if it was somehow not doing so it should charge fully while on AC power for 6 hours I would think.


2. The following are recent changes to consider; I have changed the power options over to "power saver" and I could have sworn I changed something where I chose battery health over something else, though I don't see that when I am looking at it now. I have also installed a new 1.35v 8gig ram stick. I am not certain this started before or after any of these changes, I only noticed it in the last week or so and that is after these changes, but not directly after.


Does anyone know why this might be occurring, is this related to that battery health setting I can't seem to relocate?



Solved! See the solution

You can get at the Lenovo Energy Management app, Energy Management.exe, from here:


C:\Program Files (x86)\Lenovo\Energy Management\


It shows up in the notification area with the bottom taskbar for me, but I have it enable to always show all icons.

This happens when you go to the Lenovo Energy Management Software (from bottom right, near the clock on desktop) and choose battery health instead of maximum battery life. 


In optimized battery health, it stops charging battery at around 60% of its capacity to reduce battery degradation.

This. I was freaking out thinking I had a bad battery. It's the "optimized battery health" option in Lenovo Energy Management. Sounds all well and good, but they should REALLY give you are warning about this. I imagine tech support gets a lot of calls because of this, had me stumped for half a day and I'm rather computer literate.

great! I mean to find something like this, is it just good luck or hundreds hours searching :-)
I spent maybe 4 hours to find your post and find really strange software causing things like this without any warning.
thanks a lot!
