@Dino_Mazali, Hello and welcome to the HP Support Community!

Thanks for posting your question. I'm here to help you get things back on track.

I understand your HP 14 inch Laptop PC 14-ep0000 was working earlier today but now won’t power on at your office. Since you’ve already tried the basic “no boot” troubleshooting steps, let’s go a bit deeper to isolate the issue.

Check for Signs of Power

• Press the power button and observe:
  • Any LED lights (on the power button, keyboard, or sides)?
  • Any fan noise or screen flicker?
• If no signs of life, proceed to the next step.

Perform a Hard Reset

This clears residual power and can resolve many startup issues:

• Disconnect the AC adapter and remove any external devices (USB drives, mouse, etc.).
• Press and hold the power button for 15 seconds.
• Reconnect only the AC adapter (no battery if removable) and try powering on.

Try a Different Power Source

• Use a different wall outlet or power strip.
• If possible, test with a known working HP AC adapter (same voltage and connector).

Check for Display Issues

Sometimes the laptop powers on but the screen stays black:

• Shine a flashlight at an angle on the screen to check for faint images.
• Connect to an external monitor via HDMI to test display output.

BIOS Recovery (if applicable)

If the laptop shows a blinking LED pattern or powers on briefly:

• Try BIOS recovery using this guide:

Battery and Adapter Check

Use HP’s diagnostic tool if the laptop powers on intermittently:

I hope the information shared has been useful and resolves your concern.

Wishing you a smooth and hassle-free experience ahead!
