Inconsistent and unreliable battery life

[Duner25]

QUESTION: What is causing my battery to charge slow and drain fast? Why is the battery indicator giving such varied readings? How can this be fixed?

Recently, I have been experiencing consistency issues with my Envy Notebook17t. The battery seems to charge, all be it slowly, to full. However, when I unplug it, the battery drains by large amounts in a matter of minutes. I charged it last light to a full battery. I then shut it down. I woke up to a batter at 75%. Then about 5 minutes later, I got a low battery warning and it shut down. After plugging it in and turning it on again. the battery indicator indicated that it was charging and currently at 48%. I have gone through the exercise of changing battery optimization settings, reducing background running apps, limiting the number of open programs etc, This is obviously not a brand new computer but I was always pleased with by battery life on this particular computer.

It is likely one of a couple of things:

• Battery needs to be replaced (product introduced in 2016)

Part Numbers and procedure:

HP ENVY m7 Notebook PC (model numbers used 17-u000 through 17-u099) - Maintenance and Service Guide

Chapter 5 - Removal and Replacement Procedures > Battery - Page 26

Or, perhaps...

• The ACPI driver needs to be reinstalled.

Battery does not charge, possibly after Microsoft Updates (issue has been reported at least back to 2011)

Solution (Paraphrased content)

• Unplug the charger
• Switch off the computer for 30 minutes, boot / start the computer, and log in
• Control Panel > icon view > Device Manager > Open Batteries > Right-Click “Microsoft ACPI-Compliant Control Method Battery" > Uninstall > Remove existing driver
• Shut down the computer
• If the battery is removable, remove the battery for one minute > Replace battery (Skip for non-removable battery)
• Start the computer and log in
• Control Panel > icon view > Device Manager > Open Batteries > Right-Click “Microsoft ACPI-Compliant Control Method Battery" > tab Action > Check for hardware changes (reinstalls the driver)
