Hello,

Every time when i turn on my laptop with an USB connected to it, it will just show a black screen with my caps-lock LED flashing 3 long times and then 2 short times. Please, if someone knows how to solve this issue, i would be glad to know.

Hi @Hank102 

Welcome to HP Support Community.

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

The flashing caps lock LED pattern (3 long flashes followed by 2 short flashes) on HP laptops indicates a hardware issue, often related to the BIOS or memory. Here’s how to troubleshoot the problem:

1. Remove External Devices:

• Disconnect all USB devices and peripherals from the laptop. Sometimes, a faulty USB device can cause boot issues.

2. Perform a Hard Reset:

• Power off the laptop.
• Disconnect the power adapter and remove the battery (if removable).
• Press and hold the power button for about 15 seconds to discharge any residual power.
• Reconnect the battery and power adapter, then try turning it on.

3. Check RAM:

• If you're comfortable doing so, try reseating the RAM:
  • Turn off the laptop and remove the battery and power adapter.
  • Open the access panel (if applicable), carefully remove the RAM sticks, and then reinsert them firmly.

4. Reset BIOS:

• If you can access the BIOS (usually by pressing Esc, F2, or F10 during startup), try resetting it to default settings.

5. Check for Faulty RAM:

• If you have multiple RAM sticks, try booting with just one stick at a time to see if one of them is faulty.

6. Disconnect Hard Drive:

• If the laptop continues to fail, disconnect the hard drive and see if it will at least pass the POST (Power-On Self-Test). If it does, the issue may be with the hard drive.

I hope this helps.

Take care and have a good day.
