HP Pavilion 15 3 Long 2 Short White caps lock blinks

[existentialistd]

Hello there! I need help with my HP Pavilion 15. Whenever I try to start my laptop, the caps lock key blinks 5 times (3 long and 2 short) with a white light. I'm unable to put my hands on It (hardware-wise), so I'd likes to know if there are some software procedures I can try or I should directly go to someone who can detect and handle the problem. Mind you that I didn't do anything to the laptop, every intervention to the device was done by experts during the warranty periodo and that I did not retouched it since the last time it was brought in for a battery related problem.

The 3 long and 2 short blink sequence on the caps lock key is a diagnostic indicator of a hardware issue, specifically a problem with the memory module(s). You may try the following software steps to troubleshoot the issue:

1. Remove the battery and unplug the AC adapter.
2. Hold the power button down for 15 seconds to discharge any residual power.
3. Reconnect the battery and plug in the AC adapter.
4. Press the power button to start the laptop.

If the issue persists, it's recommended to take the laptop to a professional repair center for further diagnosis and repair.
