Laptop not working without charger and now won't even start

[Jjtttyy]

My HP pavilion laptop is not turning on despite being connected to a charger... It wasn't working without it earlier.... It's been 4 years since I bought it.

Hi @Jjtttyy,

Welcome to the HP Support Community.
 

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

Since your HP Pavilion laptop is not turning on even when connected to a charger, and it previously only worked while plugged in, this could point to a battery, power supply, or motherboard issue. Here’s a step-by-step guide to help you troubleshoot:

1. Hard Reset the Laptop

• Disconnect the charger.
• Press and hold the power button for 15–20 seconds.
• Reconnect the charger and try powering it on.

2. Check the Power Adapter and Charging Port

• Ensure the charging LED near the port lights up.
• Try a different compatible charger if available.
• Inspect the charging port for dust or damage.

3. Try a BIOS Power Reset (if keyboard lights blink)

• Press and hold Windows + B, then press and hold the power button for 2–3 seconds.
• Release all keys and wait to see if the BIOS recovery screen appears.

4. Remove Battery (if removable)

• If your model has a removable battery, take it out.
• Plug in the charger without the battery and try turning it on.

5. Check for Signs of Life

• Any LED lights, fan noise, or keyboard backlight?
• If completely dead, it could be a motherboard or power circuit failure.

I hope this helps.

Take care, and have an amazing day!
