laptop battery charging

[BramQ]

My laptop won't charge the battery completely (stops at 75%). At app. 40% of the battery the laptop suddenly shuts down...

The battery is OK (checked). The laptop and genuine battery are 2 years old.

What to do to get the battery working as before again?

Hi! @BramQ,

Have you tried charging your laptop using a different adapter or battery?

Were there any recent windows update on the PC?

Please try the steps recommended below and check if it helps.

Check the BIOS (F.34 and later) to confirm the setting is set to Full Charge, if it is not, change the BIOS setting to Full Charge.

Power on the unit.
Press F10 to enter the BIOS.
Select the Power option. 

Full Charge: The battery charge stops at 91~100%. 
Extended Life of Battery Pack: The battery charge stops at 76~80%. 
Optimize Life of Battery Pack: The battery charge stops at 46~50%. 

Save changes and exit the BIOS.

If the above steps do not fix the issue, upgrade the BIOS to version F.34 (SP93520). 

Update the BIOS using this link. Click Here

Remove the AC adapter and discharge battery capacity to 10 percent or lower.
Re-connect the AC adapter and check if the battery can be charged to 95 to 100 percent (95 to 100% is normal).
If upgrading to F.45 does not fix the issue, replace the battery.
If replacing the battery does not resolve the issue, follow the standard repair process to get the issue resolved.

Run Power Troubleshooter.

On Cortana, enter  Troubleshooter then select Troubleshooting.
Click Improve power usage to open the window, then click Next. 
This should run the troubleshooter and can fix any detected issues. You may try restarting your computer and charge your battery again.

Lastly, try running a battery test from the F2 system diagnostics page and check if the hardware components on the PC are functioning correctly.

Let me know how it goes!

Thank you for replying.

I have updatet the BIOS from F.21 to F.34. But in the menu I could not find the power option in the main menu...

Windows Cortana is not available in my country so that solution fails.

All the updates are installed. What are my options now?

Hi! @BramQ,

Thanks or writing back to us.

Did you try running a battery test from the F2 page?

Try updating the HP AC power control utility to the latest version and check if it helps.

Not only update but also run "C:\Program Files\Hewlett-Packard\HP AC Power Control\PSOFF.exe" it will disable any battery charging limits if they are set.
