Windows 10, HP laptop battery "plugged in, not charging"

After installing Windows 10 on my HP Pavilion g6-2197sa laptop, I have had problems charging the battery. The battery icon reports something like "79% available (plugged in, not charging)."

I can, sometimes, temporarily fix this problem by following these steps:

1. Shut down
2. Remove battery
3. Boot up on AC power
4. Uninstall the ACPI-Compliant Control Method Battery driver
5. Shut down
6. Reinsert battery
7. Reboot

However, I bought a new battery to see whether the issue lay with my original battery, and it worked fine for a while before it also succumbed to the issue. Now the new battery no longer charges even after repeating the above process. My original battery seems to charge temporarily after I repeat the above process.

I have further noticed that my AC light flashes continuously while plugged in, whether the laptop is on or off, which it never used to do.

Also, note that the battery never charges, now matter how low the available remaining power gets - my problem doesn't appear (to me) to be a feature designed to prolong battery life.

I would really like to fix this problem permanently but am completely stumped. Cheers!

Solution 1:

This may be not a problem but it should be a feature of your energy manager or power manager driver. I am using Lenovo laptop and in this the new power manager driver have the feature that you can put a battery into conservation mode that protect battery to charge above 60% (in lenovo limit is 60%) after that it shows plugged in but not charging. This is feature is useful when you want to continuously use laptop without worrying about charging of battery. And I also observed that this feature still remain even if you change OS, shutdown and than charge it. The only way to turn off the conservation mode is to off from the same software again. So check your laptops power manager driver may be you can find this type of feature with the name conservation mode or any other name and turn it off.

Edit:

In my Lenovo Laptop I've Found the way to turn off the feature which I've mentioned above. The trick is very simple. I shut down the computer and remove the battery and long press the power button without any power source (around 40 second).

Solution 2:

For HP laptop there is a new power management tool/driver which actually (if turn on) try to use AC power after a certain % of battery draining. In my case even if I have the power on my battery drain constantly upto 15% and then stays there. Its annoying if you are not aware about it and if you are planning to use your laptop on battery for longer time turn off this feature first.

Steps in Windows 10:

1. Go to search (next to windows icon in the left side dock)
2. Search for HP AC Power control
3. Click it and turn off or change the time
