My Windows 11 laptop keeps on powering off when it reaches 30%, and when I press the power button a low battery symbol appears. Can someone please help me fix this problem?

Window 10 - No warning for low battery.

Hi William,

Your concern about the low battery notification on your device can be facilitated by the Power Options section of Windows. To check if Low battery notification is activated, we'd recommend performing the following:

• Search and launch Control Panel using Cortana.
• In the Search Control Panel box, type Power Options.
• Click on Edit power plan.
• Locate and click Change advanced power settings.
• Locate and collapse the Battery category.
• Locate and collapse Low battery notification.
• On battery must be tagged as On.
• If it's already on, locate and increase Low battery level to at least 10%.

Let us know how it goes after you've performed the steps.

 

low performance when battery is disconnected

Hello,



Thank you for writing to Microsoft Community Forums.

• Who is the manufacturer of the computer?
  
• When the battery was taken out, was the power plan setting changed?
  
• What is the current BIOS version running on your computer? If the BIOS is outdated, please get in touch with the computer manufacturer and get the BIOS updated.
  

Disclaimer:Modifying BIOS/ complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting
properly. Microsoft cannot guarantee that any problems resulting from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.




Since the battery is swollen, I suggest you to get the battery replaced.



There should not be any low performance issue, if the battery is removed from the laptop. I suggest you to the inbuilt troubleshooter for Power and have a check with the issue.

• Press Windows logo key + I to open
  Settings.
  
• Select Update & Security.
  
• Click on Troubleshoot.
  
• Select Power and run the troubleshooter.
  

Please check with the Power plan settings from control panel and restore the plan to default settings. If you still face the same issue, I suggest you to create a new power plan, then check with issue.



Follow the steps mentioned below to create a new power plan.

1. Press Windows logo key + R and type
   control panel, click on OK.
   
2. Click on Power options.
   
3. Click on Create a Power plan.
   
4. Select an option from Balanced,
   Power saver and High performance, name the plan and click
   Next to continue.
   
5. Change the sleep and display setting if needed, and hit
   Create to finish the task and have a check with the issue.
   

Hope it helps.
