Hi @kimrego,

Welcome to HP Support Community.

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

If your HP laptop (model 15-dy2152wm) won't power up but shows a blinking power light, it indicates a potential hardware issue. Here are some steps to diagnose and potentially resolve the problem:

Basic Troubleshooting Steps

Power Reset:

• Disconnect all external devices (USB drives, printers, etc.).
• Unplug the power adapter and remove the battery (if it's removable).
• Press and hold the power button for 30 seconds to discharge any residual power.
• Reconnect the power adapter (leave the battery out if removable) and try to power on the laptop.

Check the Power Adapter:

• Ensure that the power adapter is functioning correctly. If possible, test it with another compatible HP laptop or use a multimeter to check its output voltage.
• Inspect the power adapter and cable for any signs of damage.

Inspect for Loose Connections:

• Ensure that the power adapter is securely connected to the laptop and the power outlet.
• Check the power port on the laptop for any debris or damage.

Advanced Troubleshooting Steps

Blinking Light Codes:

• The blinking power light often follows a pattern that indicates specific hardware issues. Count the number of blinks and the pattern (e.g., long and short blinks).
• Refer to the HP support website for the blink code meanings specific to your laptop model.

BIOS Reset:

• Sometimes, resetting the BIOS can help. To do this, turn off the laptop, then press and hold the Windows + B keys, and while holding these keys, press and hold the Power button for 2-3 seconds, then release the Power button but continue holding the Windows + B keys until the BIOS recovery screen appears.

Reseat RAM and Storage:

• If you are comfortable opening your laptop, try reseating the RAM and storage drive. Sometimes, these components can become loose and cause startup issues.
• To do this, remove the back cover of the laptop, carefully remove the RAM and storage drive, and then reinsert them securely.

External Display Test:

• Connect your laptop to an external monitor or TV using HDMI or VGA. This can help determine if the issue is with the internal display.

Check for Overheating:

• Ensure that the laptop vents are not blocked and that the internal fans are working. Overheating can prevent the laptop from powering on.

I hope this helps.

Take care and have a good day.
