Laptop Won’t Turn on Again

[caroro]

My HP Envy x360 has had this issue where it will completely turn off and won’t turn on again. There are no lights and none of the fans turn on. I know the problem is starting when I try to turn it on and the light will turn on for a few seconds and then off again. This is the THIRD TIME this has happened to me. This laptop has just ended its warranty and I had it fixed three times while it was under warranty (the first time they sent it back and it still wasn’t working). I know that the laptop is no longer under warranty so they probably won’t do anything, but it’s ridiculous that HP keeps sending me a broken laptop. I don’t overuse my laptop and I always shut it off when I’m done using it. I was told that they replaced the motherboard for each repair. What can I do to fix this issue.

Hi @caroro 

Welcome to the HP Support Community! We're here to help you get back up and running.

You're absolutely right to feel frustrated—especially after multiple repairs and a recurring issue that seems to defy resolution. When a laptop like the HP Envy x360 powers on briefly and then shuts off with no lights or fan activity, even after motherboard replacements, it strongly suggests a system-level fault.

Let’s walk through a structured approach to help you isolate the issue and explore your options—even outside warranty.

Step-by-Step Recovery and Diagnosis

1. Perform a Full Embedded Controller Reset

This clears residual power and resets the system board:

• Disconnect all peripherals and unplug the charger
• Press and hold the Power button for 30 seconds
• Leave the laptop unplugged for another 60 seconds
• Plug the charger directly into a wall outlet (avoid surge protectors)
• Press the Power button once (do not hold)

Watch for any flicker from the keyboard backlight, fan spin, or LED indicators.

2. Test with Battery Removed (If Removable)

If your model allows battery removal:

• Remove the battery and connect only the charger
• Try powering on the laptop
• If it boots, the battery may be shorting the system

If the battery is internal, skip this step and proceed.

3. Check for Diagnostic Blink Codes

HP laptops often use LED blink patterns to signal hardware faults:

• Observe the Caps Lock, Power, or Charging LED
• Count any blinks or patterns (e.g., 5 long, 3 short)
• Reference HP’s Blink Code Guide for interpretation

4. Try External Display and Alternate Charger

• Connect to an external monitor via HDMI or USB-C
• Use a second compatible HP charger if available
• If the external display works, the issue may be with the internal panel or ribbon cable

You’ve done everything right—careful usage, proper shutdowns, and multiple service attempts. Let’s make sure your voice is heard and your system gets the reliability it should have had from the start. 

I’m here to support you every step of the way.
