Hi @Punkg,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

The blinking Caps Lock light on your HP laptop usually indicates a hardware issue, often related to the motherboard or BIOS. Here's a step-by-step guide to help troubleshoot.
 

Count the Blinks

• The number of blinks can indicate the type of error. For example, a blinking pattern like two blinks followed by a pause might mean a specific issue like a system board failure. Check your user manual or HP's website for a more detailed blink code for your model.

Perform a Hard Reset

• Turn off your laptop.
• Disconnect the power adapter and remove the battery (if removable).
• Press and hold the power button for about 15-20 seconds to discharge any residual power.
• Reinsert the battery (if removed) and plug in the power adapter.
• Try turning on the laptop again.

Check for External Peripherals

• Disconnect any USB devices, external monitors, or SD cards.
• Restart the laptop to see if it powers on.

Try a BIOS Reset

• If the laptop's power button and screen are unresponsive, you can attempt a BIOS recovery by:
  1. Press and hold the Windows key and the B key while pressing the power button.
  2. Keep both keys held down for about 5-10 seconds, then release them.
  3. The laptop should begin a recovery process.

Reseat the RAM

• If you're comfortable with hardware, you can try reseating the RAM:
  1. Power off the laptop and remove the battery and power cable.
  2. Open the back panel and carefully remove the RAM sticks.
  3. Reinsert the RAM and make sure it's seated properly.
  4. Try turning on the laptop again.

I hope this helps.

Take care and have a good day.
