Laptop Shuts Down Without Warning at 50% Battery

[Yehuda_Gefen]

Hello everyone,

I seem to have a problem with the battery and its software. The symptoms...

• The device never provides a low battery warning
• Shuts down suddenly without warning if not plugged in...at reboot, battery display shows ~50%
• Currently plugged in and battery shows 91% available (plugged in, not charging)... will not charge to 100% as it did originally when new (18 months old)
• Will only charge to 100% when device is powered down

Good Day. A warm welcome to the HP community. 

I reviewed the case regarding the charging issue. I will be delighted to assist you here.  

Superb description and terrific observations made before posting. Kudos to you for that. 😉 

I have a few steps listed below that should help you resolve this concern: 

Unplug the charge and use the laptop until the battery drains to 15%. 

Turn off the laptop and turn it back on after 30mins. 

Reinstalled Microsoft ACPI-Compliant Control Method Battery under device manager, 

Restart the computer and the issue should be fixed. 
 

Also, Go through them all and let me know what you have determined is causing the issue.

Hi,

Regretfully, no progress. 

I thought about overheating and cleaned the components with compressed air - no help. BTW, CPU is running at 40 - 50 degrees.

Also, your reply "To understand more about how your battery works: Click here" leads to a 404 page.

Other ideas?
