Battery not working properly and cooling fan 90b corrupted

[Jatin8]

I have hp laptop 15 bw0xx product no. 3EJ39PA#ACJ with windows 10 . The laptop works normally when plugged in but as soon as I remove power , irrespective of what the battery is , it shuts off after about half an hour. The shut down is not normal . It just shuts without any message with a blink sound. I checked it with replacing battery of another laptop with mine and it works well . I guess the problem is in battery. But after I replaced the battery , the laptop started showing a error message on booting up. it says a cooling fan 90b is not working properly and can damage your laptop. There is very slow and bit noisy sound from cooling fans when i heard it. Please help me!

Thank you for posting on the HP Support Community.

• Did this happen after a recent window or software update?
• Did you try another charger?
• Do you get any error message on your notebook (Such as Plugged in, not charging, etc.)?

While you respond to that, let's try these steps: 

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.

And the error 90B message indicates that the system fan is not spinning at the expected speed. This message occurs to help prevent costly damage to the computer.

To fix this error, use the following steps:

1. Press Enter to clear the message and allow the system to boot to the Windows Desktop.
2. Shut down the computer, and then inspect and clean the exterior vents to remove dust buildup by blowing air through the vent openings. Dust can accumulate inside the vent openings and around internal cooling components, preventing the removal of heat.

For more information on reducing heat inside your computer, see Reducing Heat Inside the PC.

1. After you remove the dust, turn on the computer. If the error message persists, continue with these steps.
2. Perform a hard reset. Performing a hard reset can reset recorded thermal values in memory and enable you to use the computer again, even if only for a short time to access and save any important files before service.

For more information on performing a hard reset, see Use Hard Reset to Resolve Hardware and Software Issues.

• In some cases, updating the BIOS might help prevent this error from occurring.

For more information on how to update the BIOS, see Updating the BIOS.
