Battery Icon Not Working

[WillTaylor]

I have come across an issue in recent days where my battery icon has stopped giving an accurate reading, and it says 99% charged irrespective of how much charge is actually in the battery. I have made no recent changes to my laptop, and the battery did not seem at all degraded before this issue came up. 

To try to fix it, I have tried:

- Turning it on and off again, including leaving it off for some time

- Updating the system BIOS

- Running a battery health check

I have not yet tried to calibrate the battery, as I'm not sure it will turn off charging when it is 100% full if the battery is not sure how full it is, and overhead. 

Is there any way to fix this?

HP has produced and brought to market more than a thousand different models of notebooks and desktop PCs over the years.

It is difficult to help you if we don't know the hardware configuration of the laptop that you own.

Method #1: If the notebook will boot into Windows, you can retrieve your Product Number by pressing Fn + Esc key.

Method #2: Press the power button and immediately tap the F10 key to invoke the BIOS. In the Main section, you will find the Product number or Product ID. Post that in your next reply in your thread.

Method #3: Press the power button and immediately tap the F2 key.

Method #4: If powering on is not an option, take a look at the bottom of the laptop for the label with the product name and product number. For a desktop look at the rear for the label.

If your laptop has HP Hardware Diagnostics UEFI version 10.3.0.0, there is a System Information section that also has the Product ID.
We need that information, along with the installed Operating System information to help you.
