Hi @Aabor 

Welcome to HP Support Community.

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

The three beeps with the Caps Lock flashing is an error code specific to HP laptops, and it typically indicates a hardware issue. Based on the behavior you're describing, the error is most commonly linked to the memory (RAM) or possibly the motherboard.

Here's what the three-beep code typically means:

• 3 short beeps: This generally indicates a memory (RAM) error. It could mean there's a problem with the RAM module or the RAM slot.

Given that you've already tried reseating the RAM and other components, here are some additional troubleshooting steps you can try:

1. Try Reseating the RAM Again

• Remove both RAM modules (if you have two) from their slots.
• Clean the RAM contacts: Gently wipe the golden pins on the RAM with a lint-free cloth, or use a soft brush to remove any dust or debris.
• Reinstall the RAM one at a time in different slots. If you have two modules, try inserting only one at a time to see if the issue persists with one specific module.

2. Test the RAM

• If you have access to spare RAM or another compatible laptop, try swapping in the working RAM to see if the problem goes away.
• If you have only one stick of RAM, and you've reseated it with no change, try testing it in a different slot or using another stick of RAM, if possible, to rule out a faulty stick or slot.

3. Check for Overheating or Loose Connections

• Overheating can sometimes cause hardware failures or instability, so ensure the laptop is cool and that there's no dust blocking fans or cooling vents.
• Check all internal connections (like the hard drive, battery, keyboard, etc.) to make sure nothing is loose.

4. Reset the CMOS Battery

• If possible, try resetting the CMOS battery (a small coin-cell battery on the motherboard), as this can sometimes resolve boot issues.
  1. Remove the CMOS battery for about 5 minutes.
  2. Reinstall the battery and try powering the laptop on again.

5. Perform a Hard Reset

• Perform a hard reset to drain any residual power:
  1. Power off the laptop completely and disconnect the AC adapter.
  2. Remove the battery.
  3. Hold the power button down for 15-30 seconds to drain any residual power.
  4. Reconnect the battery and the AC adapter, and try turning it on again.

I hope this helps.

Take care and have a good day.
