I have a hp pavillion 15 laptop. When I turn it on the power button lights up but goes off in 2-3 seconds. Tried all possible ways of force start but nothing is working

Hi @Abhiabhi3,

Welcome to the HP Support Community!

Thanks for reaching out!

We're thrilled to have the opportunity to assist you and provide a solution.

I understand your HP Pavilion 15 laptop where the power light turns on for a few seconds and then shuts off without starting. Let’s go through a few checks.

Perform a Hard Reset

• Disconnect the power adapter from the laptop.
• Remove any USB devices, external drives, or memory cards.
• If the battery is removable, remove it from the laptop.
• Press and hold the Power button for 15–20 seconds.
• Reconnect only the power adapter (leave the battery out if removable) and try turning the laptop on.

Note: This clears residual electrical charge that may prevent the system from starting.

Check the Power Adapter and Charging Indicator

• Plug the power adapter directly into a wall outlet.
• Connect it to the laptop and observe the charging LED near the charging port.
• Confirm whether the light stays solid, blinking, or off.
• Try another compatible outlet if the light does not appear.

Test Startup With Minimal Hardware

• Disconnect all external devices from the laptop.
• Leave only the power adapter connected.
• Press the Power button once and watch for:
• Fan movement
• Keyboard backlight
• Screen activity
• If the light still turns off after a few seconds, attempt the start again after waiting 30 seconds.

Check the Display

• Turn the laptop on again.
• Watch the screen closely for any HP logo or brief flash of light.
• Increase the screen brightness using the Fn + brightness key.
• If possible, connect the laptop to an external monitor using HDMI.
• Turn the laptop on to see if video appears on the external display.

Attempt the BIOS Recovery Key Combination

• Turn the laptop completely off.
• Press and hold Windows key + B.
• While holding the keys, press and hold the Power button for 2–3 seconds.
• Release the Power button but keep holding Windows + B for about 10 seconds.
• Watch for the BIOS recovery screen or system fan activity.

Note: If the power light turns off after a few seconds with no fan, display, or keyboard activity, it can indicate a hardware-level startup issue such as memory seating, power circuitry, or system board initialization.a
