My HP Spectre x360 laptop battery will not charge, white LED next to AC Adapter plug blinking

[NT84]

Someone mentioned that their HP Spectre notebook had a constantly blinking white led light next to where the ac adapter plugs in. The issue had already been answered with an accepted answer that did not solve the users question, so I am re-asking it here in the forum to give a better answer that is approved by HP (I found it on their support site). I have the same problem. It's not the adapter, and my battery check passes when I run the HP utility. However, when I look at the advanced information, I can see that one of my three battery cells is at zero charge. When I looked through the forums here, people mentioned some troubleshooting steps such as uninstalling drivers and uninstalling the battery. I can't uninstall the battery, and the other person that had the same issue tried all the other trouble-shooting steps. Here's what I found, though, HP says if the white LED light that is next to the AC adapter is blinking, it's a battery problem. So, presumably you would need to take your computer in to have your battery swapped if you have an integrated battery that can't be user-removed.

here is the link to the HP support article that mentions this. It's in the first paragraph.

Thank you for posting on HP Support Community.
 

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

Hard Reset: Follow steps from the link: https://hp.care/2GnkMa8. (do not skip any troubleshooting steps even if you feel steps are repeating)

BIOS default:

1. Turn off the computer and wait five seconds.
2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4. Press F10 to Save and Exit.
5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
6. Follow the prompts to restart your computer. If the issue persists, follow next steps.

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.

Hope this helps! Keep me posted for further assistance.

I accidentally skipped the first suggestion, Hard Reset. I got to the component check and ran the battery check. The battery actually failed at that time, with a Failure ID code of 9U0BMK-7H2AGE-MFPWLJ-C0CE03. the white LED light continued to blink. the battery remained unable to charge. Then, I realized that I had skipped the Hard Reset step. I went back to do that, even though I thought it was moot since I had already gotten the failure on the battery test. Turns out, the Hard Reset fixed the problem! My battery is charging again! Thanks, Echo_Lake!!
