Hi @malmborg20012 

Welcome to the HP Support Community! 

Thanks for posting your query! We're here to help you get back up and running.

It sounds like your HP Pavilion Notebook is experiencing a hardware failure, given the black screen, beep codes, and the blinking Caps Lock indicator. 

The blink pattern and beeps are diagnostic signals designed to point to specific issues. 

Here's what you can do to address the problem:

 

Step 1: Understand the Beep Codes and Blinking Pattern

2 blinks of Caps Lock generally indicate a BIOS corruption issue.

The beep codes may further confirm this diagnosis. HP's documentation might specify what "2 blinks, repeated 5 times" means.

 

Step 2: Perform a Hard Reset

Disconnect the power adapter and remove the battery (if removable).

Press and hold the power button for about 15 seconds to discharge residual power.

Reconnect the power adapter (without the battery) and attempt to power on.

 

Step 3: BIOS Recovery Process

If the BIOS is indeed corrupted, you may be able to recover it:

Shut down the laptop completely.

Press and hold the Windows + B keys simultaneously, and then press the Power button for 2–3 seconds while holding Windows + B.

Release the keys and power button, and if your laptop has a BIOS recovery feature, it should attempt to recover the BIOS.

 

Step 4: Check for Hardware Failures

Please follow these steps:

1) Shutdown your PC completely, as soon as you Turn on the computer repeatedly press the Esc key to enter the Startup Menu.

2) Now press the F2 key to access HP PC Hardware Diagnostics (UEFI) main menu.

3) On the HP PC Hardware Diagnostics (UEFI) main menu, click System Tests.

4) Click Extensive Test.

5) Click Run once to initiate the test.

Note: It will take few hours to complete the test.
