Battery not detected?

Hello,

So I updated today Windows 10 (KB3213986), and now my battery either displays an empty Icon saying "Unknown remaining" or "No battery is detected". BIOS is up to date as well. Anyone else has this issue? Any idea how to solve it?

The battery still works when the laptop is unplugged but it shows the "unknown remaining".

I have tried:

  • Restarting
  • Check for updates available for my drivers, including the BIOS and the Microsoft ACPI- Compliant Control Method Battery.
  • Run the command powercfg -energy, which found an error related to this: "Battery Capacity Unknown"

You may try to perform a power cycle of the laptop and check if it solves the issue.

  1. Unplug all external devices from the laptop.
  2. Take out the battery of the laptop.
  3. Press the power button of the laptop for 10-15 seconds.
  4. Insert the battery into the laptop and restart the computer.
  5. Connect the AC adapter and check.

Hope you find this helpful. If issue still persists, get back to us for further assistance.

I have similar problem after KB3213986.

- Model: Toshiba Satellite Z30-A

- Battery and charging was working fine before yesterday's update, Toshiba Health Monitor reported good battery life.

After the update:

- After a clean start Windows detects the battery state, but after a short amount of random time it either reports 0% remaining or battery unknown. However, laptop keeps working unplugged.

- The battery could not be removed from this model (without removing the back that voids warranty), but I tried a power cycle by pressing the power button for 15 sec. Problem remained.

- There is no related error message in the event log.

- powercfg /energy reports an error: "Battery:Last Full Charge (%)" is 0.

Can the update removed or any other advises?

Thanks,

Zoltan

- System restore is disabled on the machine.

- I'd rather not restore or reset the machine if there are any other solutions (it is rather time-consuming).

- I tried to manually uninstall KB3213986, but in Programs and Features it was displayed only as a Security update and not as a Cumulative Update. Nevertheless, I removed it, but it did not solve the problem. (Now Windows Update scheduled to reinstall the update.)

The first suggestion is reasonable but unfortunately it didn't work - there are more and more laptops around these days where the battery is not user accessible (I avoid those).

The second suggestion I'd classify as a very unhelpful.   Most (I hope!) people on this forum will be familiar with the Recovery Options in Windows 10.

Something in the update has obviously borked the Toshiba's battery-life driver interface to Windows.

This a fairly recent (2014) laptop and on the Toshiba site, "Toshiba recommends Windows 10 Pro".

Rather than the standard reply, which amounts to either uninstalling the update or reinstalling Windows, I'd suggest reinstalling the Toshiba drivers from the original disk or, if that is not at hand, downloading them from the Toshiba site.

I'm an old Windows hand (remember Windows 3.0 anyone?) [and CP/M and Linux and BSD] and new to these forums (take a bow Andrew!)

I'd rather hoped that MS had gotten away from the point where the standard answer to any problems was "Oh, just reinstall Windows..."

Good luck Noreen - try reinstalling the Toshs' drivers first.

Dear all,

I have had the same issue, however it has been this way before this update I believe. I am using a Razer Blade 2016. It seems that when I fully charge the machine whilst it is off, when I turn it on the following happens:

1) When it is plugged in the battery has a cross and it says the battery is not detected

2) When I unplug it shows a battery icon stating unknown battery life to remain

To work around this I find that plugging the power back into the laptop and unplugging it again helps display the battery life.

Microsoft please can you fix this in Windows 10.

Many Thanks

Hi Zukum,

Seems the problem has been fixed now. If you keep up to date with Windows insider previews the problem should go away, however they've removed time altogether from the battery read out so you'll only see how much percentage remains. 

None the less all seems ok for me, hopefully it'll help your problem too.
