battery callibration doesn't work

[daffg]

Hello! I have a battery calibration issue (when it's unplugged).

The problem is when my HP says it's around 50% charge left the notebook unexpectedly switch off.

HP assistants battery check shows Ok status.

I did manual calibration according to official HP Customer Support note but it won't help.

Please advise.

Step 02. Type "Device Manager" in the start search box & open the Device Manager
Step 03. Look for Batteries and expand it by click on the + symbol on the left
Step 04. Right Click on "Microsoft ACPI Compliant Control Method Battery" & uninstall
Note: This Battery driver will get re-installed automatically when you restart the Notebook again
Step 05. Please Shutdown the Notebook
Step 06. Please remove the Battery and unplug the Power Adapter
Step 07. Press and Hold the Power Button for full 1 Minute
Step 08. Go ahead and put back the Battery and connect the Power Adapter and restart

Next update the BIOS from this Link: https://support.hp.com/us-en/drivers

If the issue persists run a Battery Test to confirm the Hardware Functionality

- Hold the power button for at least five seconds to turn off the computer.
- Turn on the computer and immediately press Esc repeatedly, about once every second. 
- When the menu appears, press the F2 key.
- On the main menu, click Component Tests and Power > Battery

Let me know how it goes 😊

It's probably a bad battery, although the steps to recalibrate it can vary from model to model. If you have the laptop plugged in most of the time and have the battery in it, it will shorten it's life a lot faster than if you used it off power. If you have it plugged in all the time, remove the battery.
