Hi @bob1889,

Welcome to HP Support Community.

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

It sounds like your HP Pavilion x360 is experiencing a hardware issue where the laptop is not booting properly, and the power LED is blinking rapidly with no fan activity. This kind of issue can often be attributed to a hardware problem, but there are several steps you can take to troubleshoot and potentially resolve it. Here’s a detailed guide:

1. Perform a Hard Reset

• Disconnect Power: Unplug the AC adapter and remove the battery (if removable).
• Discharge Residual Power: Press and hold the power button for about 15-20 seconds to discharge any residual power.
• Reconnect Power: Plug in the AC adapter (without the battery) and try powering on the laptop.

2. Check for Loose Connections

• Open the Laptop: If you are comfortable, carefully open the laptop to check if all internal components (like the RAM, hard drive, and any cables) are properly connected.
• Reseat Components: Even though you checked the RAM, make sure it’s seated correctly. Check all other internal connections as well.

3. Test with Minimal Configuration

• Disconnect External Devices: Remove all peripherals (USB devices, external drives, etc.) and try powering on the laptop.
• Test with Minimal Configuration: If possible, test the laptop with only the essential components (CPU, one stick of RAM) to see if it can boot.

4. Inspect for Physical Damage

• Check for Signs of Damage: Look for any signs of physical damage or burnt components on the motherboard and other internal parts.

5. Try a Different Power Adapter

• Use a Known Good Adapter: If you have access to another compatible AC adapter, try using it to rule out issues with the power supply.

6. Check for Diagnostic LED Codes

• Interpret LED Blink Codes: Some HP laptops use LED blink codes to indicate hardware issues. If there are any patterns in the blinking, refer to the HP LED Blink Codes to interpret the code.

7. Perform a BIOS Recovery (if possible)

• BIOS Recovery: If your laptop has a BIOS recovery option, you might be able to recover the BIOS. This is usually done by pressing a specific key combination during power-up (e.g., Windows + B key combination). Check HP’s website or user manual for specific instructions for your model.

I hope this helps.

Take care and have a good day.

Hi,

I dont think i really need this advice anymore as the laptop as completely died (no charging led, or power light) and i've decided just to buy a new laptop as my old one wasnt reeally sufficient for what i did anyway.

But thanks for your reply

Thanks,

Bob
