Re: Yoga 3 Pro Battery Charging Problems

Does the indication state if it's charging or not charging.

Re: Yoga 3 Pro Battery Charging Problems

It says it is charging.  I'm running the calibration tool now (even though it has never successfully finished even after >24 hours of running).

Re: Yoga 3 Pro Battery Charging Problems

You have to understand how the calibration tool works. It is designed to figure out what the battery capacity is when the capacity calculation fails.

 

Let's talk about the battery for a bit. Unfortunately, lithium ion batteries are not like traditional alcalines or nickel-metal hydride batteries. Once the lithium battery discharges to a lower voltage than the nominal low limit, it becomes unsafe to recharge them. As a result, the battery voltage needs to be kept above a certain threshold or it will be permanently disabled.

 

With the charging curve of batteries, over time, the maximum voltage the battery will charge to decreases as the cells degrade. As a result, the "100%" charge point will vary based on how high the charge will go. The battery calibration program drains the battery to the theoretical 0% voltage, records the voltage level, then charges until the battery's voltage remains relatively balanced. At this point, the voltage read is the "100%" charge point.

 

In order to diagnose the charging issue further, I need to see what the battery voltage is when the charging stalls.

 

It would be greatly appreciated if you all do the following:

 

1) Download the below program:

2) Post a screenshot minus the serial number of your battery details as I have:

With this, we can determine if there is an issue with the charging circuit, or if the battery health is no good.

Re: Yoga 3 Pro Battery Charging Problems

Mine took long to start charging, but eventually did and is now on 100%.  The new BIOS worked for me, so give it some time.

Re: Yoga 3 Pro Battery Charging Problems

Hi All,

I downloaded and ran the BIOS update mentioned above by xBrav. The procedure ran smoothly and it took only a few minutes.

So far, so good. Battery is charged to 100%. Can't get any better than that! SmileyThumbUp.gif

Re: Yoga 3 Pro Battery Charging Problems

Thakyou, XBrav but how do you stop a battery from completely discharging & thus being destroyed?! If I leaave my Yoga turned-on over night it will discharge to 0% battery even before the morning - especially because battery-life is pathetic anyway! Surely Lenovo can't be this stupid!

Groan....

Is there a reason why a laptop needs to be left on unattended overnight?

Re: Yoga 3 Pro Battery Charging Problems

So if my battery is at 0%, would it be safe to modify the ini file to use BatteryCheck=0  and do the update???. Or is there a possiblity it may break it. what casued this problem? Can I roll back a update ? I already have a rma to send it in but if I dont have to to fix this issue i dont want to send it in

Yes, the icon in the taskbar will show you if it is or isn't charging.
