My HP Envy m7 battery won't charge above 71%

[Tom_in_ABQ]

My battery won't charge above 71%.  I have run battery check which says it's functioning normally.  I have also tried uninstalling the ACPI-Compliant Control Method Battery driver and that does nothing.  Any suggestions?

71% may be the best the battery can do.

Read the following information, including the critical information about Recalls.

Also included are documents that explain to how calibrate the battery (which may not work, but do at least read the data so you can decide whether to try this option).

If the battery is over a year old, or near that age, it may simply need to be replaced.

Read the information about how batteries age.

Important Update: Expansion of the Battery Safety Recall and Replacement Program for HP Notebook Computers and Mobile Workstations announced in January 2018 – Additional Batteries Affected

HP urges customers to recheck all potentially affected products

In cooperation with various government regulatory agencies HP has announced an expansion of its worldwide voluntary safety recall and replacement program for certain notebook computer and mobile workstation batteries announced in January 2018. The potentially affected batteries may have been shipped with certain HP notebook computers and mobile workstations sold worldwide from December 2015 through April 2018.

The batteries have the potential to overheat, posing a fire and burn hazard to customers.  It is essential that you check or recheck your battery, even if you did so previously and were informed that it was not affected.

HP’s primary concern is for the safety of our customers. Because these batteries pose a fire and burn hazard, it is essential to visit the HP Battery Recall website at www.hp.com/go/batteryprogram2018 as soon as possible and check your battery.

Battery will not charge when system is warm to hot

If the “not charging” issue is (only) apparent when the system is running hot (or near that point), the battery and charge system are likely overheated as well – the charge system will resume operation when the computer cools down.  Short Version:  An overheated battery / computer / charging-system will not charge the battery – this is normal behavior.

Battery seems “stuck” in a particular charge setting                                                                  

The battery might be OK and just need calibration (balance / set).

The steps to check / calibrate / replace the battery are included in this document:

Thanks for the info.  It was helpful.  My battery is not one that is subject to the recall.  When I run the diagnostics, it "passes" the test, as does my adapter.  But when I look at the test logs, it shows that it is not at full capacity -- it only is at about 70% capacity, which is consistent with my device.  I'm not sure if it is significant, but in the test logs, it shows that the Primary_ChargeControl : Failed.  I have looked at how to calibrate, but this seems to be mainly resetting what is 100% of the charge.  Perhaps I do need to purchase a new battery.  My battery is not one that is easily removable, so I guess I will need to open up the computer to do that.
