Lenovo Yoga 710-14IKB - Plugged In, No Charging

Hi everyone,

 

I have Lenovo Yoga 710-14IKB 80V4001LAX model notebook.

 

I bought it around 3 weeks ago. Everything was perfect until today. Today I noticed that the device is not charging. I made a research on the internet and saw that in many model of Lenovo there is this problem.

 

- The conservation mode was closed all the time. So it is not that. Please check the screenshot.

- I turned off the notebook, removed the cables and press the opening button for 30 seconds, and then plugged the cables in and restarted but no change.

- Updated bios and no change.

- No reached to battery as it is sealed.

 

I am really disappointed and don't know what to do. I appreciate your help.

 

Thanks in advance.

So, after waiting it to drop 93% I plugged in it and it started to charge again. Maybe it is something to protect battery but it was the first time I experienced it and worried a lot. Sorry for taking your time but maybe it will help someone else. Thanks.

Hi there, Gnrbar          -

 

Thank you for writing in to the Lenovo Forum - happy to have you here today.

 

Do this test -

 

1) Switch off the laptop.

2) Disconnect power supply. Keep the battery connected.

3) Try to Turn ON the laptop.

 

If the laptop does not turn ON, the battery is faulty.

 

Also, Try turning the laptop off, removing the battery, unplug the AC adapter, press and hold the power button for thirty seconds, install the battery back into the laptop but don't connect the power cable and try to start the laptop on battery power. 

Make sure when you are plugging the cord in for the laptop that you plug it in the normal orientation as if it still had the grounding plug so you don't reverse the polarity of the socket. I don't think it should affect anything, but it's probably better to just keep it plugged in correctly.

 

Update us how it goes.

 

 

 

 

Regards,

Re: Lenovo Yoga 710-14IKB - Plugged In, No Charging

I have had the same issue with a Lenovo Yoga 710-151KB.  

 

I returned the first one to the store. The one I have had for two weeks now only charges intermittently.  The device manager says the battery and adapter are functioning properly.

 

I think it has something to do with the way the adapter is connecting to the electrical socket.  If it moves the least bit, it stops charging and / or starts losing the charge. The laptop starts without being plugged in, but the battery cannot be removed because the machine is solid state.  (I would not be the person to open up the laptop anyhow.)

 

I am almost ready to dump the monster and go back to using a Dell. I don't want to, but this is ridiculous.

This is part of the battery's conservation circuitry.

When charging your battery from a lower percentage charge it should charge all the way (as long as conservation is off). If you plug your laptop in when the battery is still somewhere around the ~95% percentile range (different laptops do it at 93%, 95%, 98%, etc.) it will just run off AC power and NOT charge the battery. Although li-ion batteries don't suffer from the battery memory effect (like old ni-cad's), they do have a limited total number of charge cycles. This is just the internal circuitry stopping the system from wasting a 'charge cycle' just to get 5% more juice.

 

The batteries in these laptops are good quality and will (hopefully) go 200 charge cycles before they start to show limited capacity issues.

 

Edit - ...just to be clear, the battery's conservation circuitry is physically built into the battery and is separate from the conservation setting in the lenovo settings app.
