Hi @Nobeard2,

Welcome to HP Support Community.

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

For an HP 15 laptop displaying a black screen with no cursor and no disc activity, here are a few steps you can try to troubleshoot.

Perform a Hard Reset

• Power off the laptop completely.
• Disconnect any external devices (USB, HDMI, etc.).
• Remove the battery (if removable) and unplug the power adapter.
• Hold the power button for 15-30 seconds to drain any residual power.
• Reconnect the battery and power adapter (without other peripherals) and try to turn the laptop on.

Check for Display Output

• Connect an external monitor to the laptop using HDMI or VGA.
• Switch display modes by pressing the "Fn" key + the display key (usually F4 or F5 on HP laptops).
• If the external display works, the issue may be with your laptop screen.

Perform a BIOS Reset

• Power off the laptop.
• Press and hold the Windows key + B, then press and hold the Power button for 2-3 seconds, and release both.
• If the BIOS update screen appears, follow the on-screen instructions.

Check RAM

• If you are comfortable with hardware, you can remove and reinsert the RAM. Sometimes, a poor connection can cause boot issues.
• If there are two RAM sticks, try booting with one stick at a time.

Startup Recovery

• Turn on the laptop and press F11 repeatedly to access the HP Recovery Manager or Windows Recovery Environment.
• If successful, you can try a system restore or startup repair.

Check for Sounds or Beeps

• Listen for any beeps when the laptop powers on. These can indicate hardware issues (e.g., RAM or motherboard problems).

I hope this helps.

Take care and have a good day.
