Battery not charging to 100%

[gniccoli]

Hi, i have been having a problem that is apparently very common by reading on the internet. After 18 months my battery won't charge beyond 76%. 

I have tried updating the BIOS and uninstalling and reinstalling the driver, but nothing works. I have done a HP battery check and most of the time it says the battery needs replaing. Although once or twice it didnt say that. 

Any ideas?

Just so you know, notebook batteries are only warrantied for one year. at 18 months of use, the warranty is no longer valid on the battery.

The one-year battery warranty is an industry standard practice regardless of the notebook or battery manufacturer. 

Most people manage to get two to five years out of a notebook battery,  Unfortunately, you are one to whom that norm did not apply.  

You can check to see the condition of your battery by invoking Windows own Battery-report feature.

Open a command line window.

At the command prompt, type in powercfg /batteryreport and press enter. 

Now type in battery-report.html  at the command prompt and press the enter key.

That should open a browser and invoke the detailed battery report.

Take notice of the design capacity and compare it to the full charge capacity.  Even if the battery test calibrates the battery it will still not charge above the full charge capacity.

It is likely that your battery does need to be replaced, based on your description of the issue.  The battery report will help you make an informed decision on its replacement. 

Most people are not able to replace a notebook, especially an ultrabook's main battery. You can have it done at a  PC or notebook shop.

Hi, thanks for the response.

I have done this already and it says that both the design capacity and full charge capacity are the same. I don't think there is an issue with the battery capaicty, but with the computer not charging it. 

It says 76%, and sometimes it will say not charging, sometimes it will say charging. 

Updating the BIOS and reinstalling the drivers increased it from 73% to 76%.
