Dwindling Battery Life

[Gjay1]

The battery power of my HP Envy m6 1511 Notebook PC is showing signs of weakness. I don't know why.

Lately, the battery hardly stays on for more than 45 mins on full charge. Sometimes even at 65% battery life left my laptop will just power off instantly without warning. It used to give me warning when its 20% battery power left. Now even at 65-70%, the battery just dies and the Laptop goes off while am working.

The laptop itself functions perfectly though.

What can be happening to my battery? Can any one advice what I can do to revive the battery? Do I need to buy a new one?

How old is it? They do not last forever. If over 2 years old it is extremely likely the problem is as simple as the battery dying a natural death.

Hi @Gjay1,

Welcome to the HP Forum!  It is a terrific place to find answers and tips! For you to have the best experience in the HP forum I would like to direct your attention to the HP Forums Guide. First Time Here? Learn How to Post and More, When I searched for the Envy m6 1511, the results came up with  a desktop. Would you verify your model for me? HP Notebook PCs - How Do I Find My Model Number, Serial Number or Product Number?

I grasp that although you're showing 65% battery remaining, your notebook will power off without warning. Your battery power will only last about 45 minutes. Here is a link that should help with this issue. HP Notebook PCs - Testing and Calibrating the Battery (Windows 10). If the battery passes the hardware check there are a couple of other things to try. The Microsoft ACPI-Compliant Control Method Battery is basically the driver that communicates between the computer and the battery. There is a chance that it is corrupted and is reading the battery level wrong. Therefore the computer thinks the battery level is higher than what it actually is, so when it runs out of juice it shuts down.

Step 1. Go to Device Manager.
Step 2. Select Batteries.
Step 3. Right click the "Microsoft ACPI-Compliant Control Method Battery" that is listed there.
Step 4. Click Uninstall.
Step 5. At the prompt put a check in the box to remove the current driver.
Step 6. Shutdown the computer.

Step 7: Remove the battery for minute and then put it back in.

When the computer comes back up it should automatically find the driver.

Step 8. Go to Device Manager.
Step 9. Select Batteries.
Step 10. Right click the "Microsoft ACPI-Compliant Control Method Battery" that is listed there.
Step 11. Click "Search automatically for updated driver software".

If you see the Microsoft ACPI-Compliant Embedded Controller follow the same process for it.

Please let me know the outcome.

Hello Sparkles,

I tried your solution by following the steps you provided .The battery results showed that the battery needs calibration. I am going to move forward with the calibration. Will that revive the battery's ability to hold power longer?

By the way my HP ENVY m6 Notebook PC product number is: D1E93UAR#ABA.

I will get back to you after the calibration. I hope it helps.

@Huffer, the battery is 2 years but I doubt its dead. I was asked by a kind HP official to test the battery's power and follow up the results based on the test. After the test the results came up that my battery needs calibration.

I am going to move ahead with the calibration and I hope it helps. Thanks for your response.

[Huffer]

I did not say dead it is obviously clinging to some life. Go ahead and calibrate and let us know if it helps. Can't hurt. It might provide some improvement in runtime but will not make the battery good as new. Good luck.

@Sparkles,

By the way during calibration should the battery stay on or off charge?

[Huffer]

Calibration will take control of the charging, first run it all the way down and then charge it back up a couple times in an effort to correlate the actual remaining runtime to the meter you see in the battery gauge. Kind of like fine tuning.

@Huffer, Thanks, I will get back after I'm done.

HiGuys,

I went through the calibration process  3 times and on each ocassion I get the message ''Battery Calibration - SOFTWARE ERROR.

Why is that happening?
