HP dv7 laptop failure to keep a charge on internal battery

[Flash15]

I thought this problem was fixed several days ago; however, it has returned.  The laptop will not charge on a regular basis and will not work at all off of the wall outlet.  Today, after several attempts to bring it to life, I noted three amber blips when the charging cord was plugged in at the connection port.  I have not opened the case to check any voltages and feel like this is a power supply problem. Any ideas?

Welcome to HP Forums,

This is a great place to get support, find answers and tips,

Thank you for posting your query, I'll be more than glad to help you out 🙂

As I understand, your notebook does not charge and shuts down when the charger is not connected to the wall outlet,

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: https://support.hp.com/us-en/document/ish_2039298-1862169-16

(Ensure you do not share any of your personal information such as serial, phone number, email ID, etc...).

Have you performed hardware diagnostics on battery and Ac Adapter?

Did you try another charger?

Does the notebook shut down immediately (right after you unplug the charger)?

Do you get any error message on your notebook (Such as Plugged in, not charging, etc.)?

While you respond to those question, 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.

Let me know how this pans out,

Good Luck!

Thanks a lot.  Deleting/Uninstalling the ACPI option seems to be the answer.  I've been waiting to respond to see if this solved my battery and charging issues.  So far, all is good.

Thank you very much,
