My laptop won't turn on but the  light on the cap lock button and charging source are on. I have tried pressing the power button for 30s and removing power cord. Please help

@yuki111, Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding your HP Laptop not powering on!  
We're thrilled to have the opportunity to assist you and provide a solution. 

Troubleshooting Steps:

Perform a Hard Reset again

• Disconnect the power cord and remove the battery (if removable).
• Press and hold the power button for 30 seconds.
• Reconnect the power cord (leave the battery out if removable) and try turning on the laptop.

Check for Display Issues

• If the laptop powers on but the screen remains blank, try connecting an external monitor to check if the issue is with the display.

Verify Keyboard Indicators

• Since the Caps Lock light is on, check if it's blinking in a pattern. If it blinks in a specific sequence, it could indicate a hardware failure.

Try a Different Power Source

• If the charging light is on, but the laptop doesn’t power up, try using a different power adapter if available.

If these steps don’t resolve the issue, I’d need some details about your laptop:

• Laptop model
• Any recent hardware or software changes

If you’re sharing the serial number of your HP laptop, please send it via private message for security reasons. Let me know how it goes!

We hope our assistance has been helpful! 

Take care, and have an amazing day!

Hi Zoe, thanks for your feedback. I took it to a repair shop and it only came on after it was opened. That message on the screen won't go away, how do I go about that?

@yuki111, Thank you for your response!

The error message "HP Endpoint Security Controller Problem" suggests a hardware-related issue with the security controller in your HP laptop. Since the laptop now turns on but continues displaying this message, here are some steps you can try:

Restart and Check BIOS

• Turn off the laptop.
• Press the power button and keep tapping F10 to enter BIOS.
• If you can access BIOS, reset BIOS settings to default.
• Save changes and restart.

Perform a Hard Reset Again

• Disconnect the power cord and remove the battery (if removable).
• Press and hold the power button for 30 seconds.
• Reconnect power and try turning it on.

Update BIOS and Security Controller Firmware

• If you can boot into Windows, update the BIOS and HP Endpoint Security Controller firmware from HP’s official support website.

Perform a System Restore

• If the issue started recently, try restoring the system to a previous working state.

If the issue persists:

• Run HP Hardware Diagnostics:
  • Restart your laptop and press F2 during boot.
  • Select Component Tests > System Board and check for failures.

Let me know how it goes!
