Yoga 720 not charging when power on

Hi there!

Today I bought my new Lenovo Yoga 720. It looks like a perfect device, but now I have a problem.

It charging only when it's power off. But when I turn on it, charging stops.

I think there might be a problem with bad battery initialization. User guide says battery is in "transport mode". But I dont know how to disable that.

Any idea?

Thank you!

Hi NewGenerat10n,

 

Welcome to the Community Forums.

 

Similar to this discussion, would there be a specific percentage when you hover it to the battery icon. Specific threshold to prevent overcharging and thus extending battery cycle are set to defaults.

 

Hardware manual (page22) describes the steps to check operational charging. I would suggest that you try using the computer until the battery indicators goes blinking amber.

 

When it turns amber, we expect that the charge is 20% and below, then connect the charger back in and see if the led turns to blinking white (may be 2-3 hours). Soon as it turn solid white is when we expect the charge to be 80% which is a good charged battery percentage to keep.

 

Update us how it goes so we can make the next action plan.

 

Regards

Thank you for your answer!
No, in not charging on any %. It can be 10% or 30% or 44% and when I plugging in power adapter, charging starting, but only for 5-10 seconds. Then it shows "plugged in, not charging"
Now I power off my notebook and plugged in power adapter. The indicator is white and it blink every 5 seconds. Should I wait or try another ways?

Re: Yoga 720 not charging when power on

Hi NewGenerat10n,

 

Greetings.

 

Go to device manager and click on the + sign before battery.

Right click to uninstall Microsoft ACPI-Compliant Control Method Battery

Shut down the machine and restart.

 

If the same issue, check for drivers and application updates using Lenovo Vantage.

You may have a different energy management tool like Lenovo setting so that may need to update first.

Check if there is any other Windows update needed.

 

If still the same, then proceed with manual calibration.

Unplug the ac charger and continue using the it without the charger until it goes amber.

Shut down and plug the charger. 

Power on then open maybe a video or stream online then unplug the charger.

Shutdown and restart then connect back the charger to check charging.

 

Machine wise, we know that it is working but the softwares within Windows falsely read it. The procedures above would help reset it.

 

Regards

Re: Yoga 720 not charging when power on

I think you can believe me, but it's true.
I went to BIOS menu and changed "Perfomance' to "Quiet"
Aaaaaaand
It started charging!
And now I'm writing you while my notebook charging.
It's crazy.
But now I have another question. Will be my notebook slowly if in BIOS menu I choose "Quiet"?

Also when it is on battery it shows voltage 7.36-7.4
When I connecting AC it shows "Charging" for 3 seconds and voltage up to 7.65
And when it is "Plugged in, not charging", voltage is 7.51
