Battery was not charging (YOGA-C740-14IML)

2021-07-21, 21:50 PM

I have been using YOGA C740 since February 2020. The other day while using the laptop, I saw the message that battery is low, so I plugged in, however I keep receiving the same message, and eventually it shut down. How come was the battery not charging even when plugged in? It just never happened like this before, so I was wondering if I am missing something. If someone can please advise, I would really appreciate it. Thank you.

Hi YukaYoga,

 

Welcome to the Community Forums.

 

 

This could be a dead battery or just static buildup preventing the device from charging. Below you'll find some troubleshooting steps you can perform in an attempt to remedy the issue:

 

Step 1. Static Discharge on Laptop and AC adapter.
- Remove all cables attached to the laptop (hdmi, external mouse/keyboard, etc)
- Ensure device is switched OFF
- Keep the AC adapter connected to the laptop, but disconnected from the wall socket *Important*
- Hold down power button for 60 seconds
- Re-attach all cables
- Connect the AC Adapter, then let the device charge for about 2 minutes (if it does) then start up as usual.
- Try it a couple of times (2-3)

 

- Try the above with the battery disconnected as well, but without the AC adapter plugged in, if possible.

 

- In the event this doesn't help solve the issue, start the device up and disconnect it from the AC adapter and all other peripherals.
- Let the device naturally drain of battery until it turns off completely. 
- Wait a couple of minutes, then plug in the AC adapter, let it charge a couple of minutes, then power it up again.

 

 

If you are able to run the device on AC power only and boot into Windows, then continue below:

 

 

Step 2. Checking The Advanced Power Options. 
- In the Search function type : 'Edit Power Plan'
- Select "Change advanced power settings"
- Find and expand "USB Settings"
- Make sure the "USB selective suspend setting" is set to "disabled"

 

Step 3. Disable Automatic Hardware drivers update
- Click the Start Menu and select the cogwheel and then "Settings.
- Select "System" and then the "About" settings at the bottom.
- From here, select "Advanced System Settings" on the right side.
- In the new Windows, select "Hardware"
- Click "Device Installation Settings" and Select "No"
**This will prevent Windows from interfering with your hardware drivers in future updates, but keep crucial security updates rolling.

 

Step 4. Reinstall Battery drivers + Check USB Root Hubs and Generic USB hubs.
- Press Windows Key + X, select Device Manager
- Now click Batteries in the Device Manager window.
- Next, you should right-click Microsoft ACPI-Compliant Control Method Battery and select Uninstall from the context menu.
- Click Uninstall to confirm.
- While still in Device Manager, expand Universal Serial Bus Controllers.
- Right click and click properties on all USB Root Hubs and Generic USB hubs.
- Check Power Management, and make sure the computer is not allowed to turn these devices off to save power.
- Hit "Apply" and exit and then "OK".
- Restart the device and have Windows install the generic driver type for the battery to be installed.

 

Step 5. Updating the System Board drivers.
Make sure you have the newest BIOS, Chipset and Power Management drivers for your device:  
You can find and install the newest drivers from the Lenovo Support Page
Just plot in the serial number for your device and hit enter, might have to hit it twice. Then head to Drivers & Software then the BIOS, Chipset and Power Management section.
**Note: Make sure the AC adapter is connected and that you have at least 30% battery charge when performing the BIOS update.

 

In the event it still doesn't charge or boot, then it's most likely a dead battery or Power Board (DC in board) in need of replacement, depending on the Warranty of the device, I'd suggest contacting Lenovo support for your country directly (mail, e-ticket, phone) or a certified technician center to see what can be done. Most likely it will have to be sent in to be assessed by an authorized technician.

 

 

Hope this helps

 

Regards

 

Voithos
