Laptop won't run on battery

[JohnS74]

I put a new battery in our laptop in June and it has worked fine, either plugged in or on battery, until today.  Now, it will not boot up on battery alone.  If it's plugged in, it works fine but when I pull the power cord to work on battery alone, it instantly shuts down.  I ran the HP battery test and it came back saying "the battery hasn't been charged lately"...."available battery power is 100%".  It can't be both!  Any thoughts?  Thanks.

Thank you for joining HP Forums. 

It's a pleasure finding answers for your technical queries to assist you.

To provide you with an accurate solution, I'll need a few more details:

Was any update done recently?

Use the following steps to open the Component Tests menu and run battery test under power test.

1. Hold the power button for at least five seconds to turn off the computer.

2. Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.

3. On the main menu, click Component Tests.

   

4. The Component Tests menu displays.

   Your Component Tests menu might be different, depending on the components installed on your computer.

   

Battery Test - The Battery Test checks your system to make sure that the battery is functioning properly. It tests the battery and allows you to run calibration if needed.

The Battery Check test time is 2 minutes. Battery Calibration time is 2 to 4 hours.

To run the test and for battery information, follow the steps in Battery Test.

Keep me posted, how it goes!

Have a great day!

Raj1788,

Thanks for the reply.  I ran the test and the results were: " Battery Test: Primary - Passed (4)" and "Battery Test: Passed".

As for updates,  the last was on 10 October, Windows 10 Version 1803 for x64 based system (KB44629190). So it ran ok for several days after that upgrade before the problem appeared.

I should also mention this laptop was purchased in early 2011 so it's probably on its last legs.

Raj, Thanks for the suggestions but they didn't work.  An update of HP Support Assistant said there were no updates, the BIOS is F.17.  Continuing with the other steps still resulted in the laptop not working on battery alone.  No need to go further, it works ok plugged in and that will be sufficient until we decide on a new laptop.

It seems that it could be a hardware issue.
