Hi @Langelihle78,

Welcome to HP Support Community.

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

If your HP 15 laptop shows a black screen and won't start, but you hear one beep and then the fan stops, this might indicate a hardware issue. Here's a troubleshooting guide.

Perform a Hard Reset:

• Disconnect the laptop from power.
• Remove the battery (if it's removable).
• Press and hold the Power button for 15-20 seconds.
• Reconnect the battery and power cable.
• Try turning the laptop back on.

Check the Power Source:

• Ensure the power adapter is working by trying a different outlet or using another compatible adapter.
• Confirm that the charging port is clean and not damaged.

Test the RAM:

• If possible, open the back of the laptop to access the RAM modules.
• Remove and reseat the RAM sticks or try booting with only one stick if you have multiple.

Perform a BIOS Reset:

• Turn the laptop off.
• Hold the Windows + B keys and then press and hold the Power button for 2-3 seconds.
• Release the Power button while still holding the Windows + B keys until the BIOS recovery screen appears (if possible).

Check for Loose Connections:

• Inspect the internal connections if you're comfortable opening the laptop.
• Ensure the RAM, hard drive/SSD, and other components are securely connected.

Examine the Beep Code:

• The beep you hear may be part of an error code. In some cases, one beep can indicate a minor issue or a sign of motherboard or display problems.

I hope this helps.

Take care and have a good day.
