HP Pavillion 15-cs0053cl charging light blinking continously when pluged in and also when shut down

[BossOlu]

I bought a brand new HP Pavilion 15-cs0053cl (HP Pavilion laptop 15-cs0xxx 8th Generation intel core i5 1.6GHz Win 10
bios version - F.07, 12/11/2018) but immediately I connected the charger that came with the laptop to the charging port and powered it on the  charging light kept blinking white  (3 short blinks) continuously when I shut down the computer and disconnected the charger the charging light still kept blinking (3 short white blinks) continuously till the next day It has not stopped blinking since the first power on. The laptop has an integrated battery that cannot be removed.

When I shutdown the laptop the charging light still keeps blinking white. I took a look at the battery status before shutting down the battery it was 93% full when I powered it on the next day it was 90% which shows that the blinking light is depleting the battery

When I checked the battery status it displays "Plugged in, Charging" The battery actually charged till it was full after using the computer for a while I charged it again and it still charged till it was full. However when the laptop is powered down and the charger is connected it does not charge.

Please help, I am concerned that this may be a faulty motherboard problem that might cause some kind of problems later. I will appreciate any suggestion

Thank you for posting on the HP Support Community.

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

Run hardware diagnostics test on battery and Charger:

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.

• If possible, try an alternate charger.

Hope this helps! Keep me posted for further assistance.
