Hi @Yan18,

Welcome to HP Support Community.

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

If your HP laptop's power light turns on for a few seconds and then turns off without the laptop fully booting up, there could be a few potential issues causing this behavior. Here are some steps you can try to troubleshoot the problem.

• Check the power adapter: Make sure the power adapter is securely plugged into both the laptop and the power outlet. If possible, try using a different power outlet or a different power adapter to see if the issue persists.
• Remove external devices: Disconnect all external devices such as USB drives, external monitors, printers, etc., and then try turning on the laptop again. Sometimes, a malfunctioning external device can cause startup issues.
• Remove the battery (if removable): If your laptop has a removable battery, try removing it, then press and hold the power button for about 30 seconds to drain any residual power. Reinsert the battery and try turning on the laptop again.
• Check for overheating: Overheating can sometimes cause a laptop to shut down shortly after being powered on. Make sure the laptop's vents are clear of dust and debris, and consider using a laptop cooling pad to help dissipate heat.
• Reset BIOS/UEFI settings: If you're comfortable doing so, you can try resetting the BIOS or UEFI settings to their default values. This process varies depending on your laptop model, so refer to the HP documentation for instructions.
• Perform a power reset: Disconnect the power adapter and remove the battery (if removable). Press and hold the power button for about 15-20 seconds to discharge any residual power. Then, reconnect the power adapter (without the battery, if it's removable) and try turning on the laptop again.
• Hardware issue: If none of the above steps resolve the issue, there may be a hardware problem with your laptop, such as a faulty power button, motherboard issue, or other internal component failure. 

By going through these steps, you should be able to determine the cause of the issue and take appropriate action to resolve it.

I hope this helps.

Take care and have a good day.
