MY LAPTOP BATTERY

[SANAT7]

My laptop battery was last changed in March 2017.  Now  for last few days it is not giving indication when 14% is left or when 11% is left. All of a sudden the computer turns off. When I recharge and switch on I find battery level at 30 , 40 or sometimes 50 % . Why is this happening ? Battery check in HP support assistant  indicates battery is okay. It does not ask me to replace battery ! Will somebody please help ? Also none of the phone numbers of HP service centre in Pune is reachable !

Thank you for posting on the HP Support Community.

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

• What is the product number of your device? Use this link to find it: http://support.hp.com/us-en/document/c03754824  (Ensure you do not share any of your personal information such as serial, phone number, email ID, etc...).

I have a few troubleshooting steps, you could perform to isolate the issue:

Run hardware diagnostics test on battery and Charger: (this troubleshooting steps for all the HP Notebook) 

Use the following steps to open the Component Tests menu.

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.
5. To run both tests simultaneously, in the Component Tests menu, click Power Source, and then click Run once. Each component can also be tested individually.

AC Adapter Test:

The AC Adapter test provides an interactive test to determine if the AC power adapter is functioning properly. A good battery is required for this test. Before running the AC Adapter Test, HP recommends verifying that your computer can receive power by connecting a known working AC adapter.

Follow these steps to perform the AC Adapter Test.

• In the Component Tests menu, click Power, and then click an AC Adapter Test.
• Click Run once.
• The AC Adapter Test begins.
• When the test is complete, the results are displayed on the screen.

Battery Test:

Follow these steps to perform the Battery Test:

1. In the Component Tests menu, click Power, and then click Battery.
2. Click Run once. The Battery Test begins.
3. When the battery test is complete, the results are displayed on the screen. For additional battery information, click Battery Details.

If the test passes, continue with these steps:

1. Go to Start, search for Device Manager, and open this result.

2. Expand batteries.

3. Right-click on the ACPI option (usually the 2nd option) and select delete or uninstall. Follow the prompts.

4. Shut down the computer. 

5. Disconnect the charger.

6. Remove the battery.

7. Hold down the power button for 1 minute.

8. Insert the battery only.

9. Attempt to turn the battery on.

Hope this helps! Keep me posted for further assistance.
