HP envy x360 won't turn on. Continuous blinking power button light

[Miles_Ke]

I have an Hp envy x360 14-es0xxx laptop with a continuous white blinking power button light when I turn it on. The light blinks while on battery and if I disconnect the battery and just use the power cord it still flashes and with both connected it still does. I have updated the bios and tried a hard reset with battery unplugged and power cord unplugged and holding down the power button for 60 seconds. I can't think of anything else to try.

Hi @Miles_Ke,

Welcome to the HP Support Community.
 

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

The continuous white blinking power button light on your HP Envy x360 14-es0xxx can indicate a range of issues. Here are some diagnostic steps and solutions to try:
 

1. Power Reset:
   • Since you have already attempted a power reset with the battery and power cord unplugged, repeat the process to ensure any charge is drained from the system.
   • Disconnect all external devices and peripherals.
      
2. Check AC Adapter and Power Source:
   • Ensure the AC adapter and power cord are functioning properly. Check for any visible damage.
   • Test the adapter with another compatible HP laptop if possible, or try using a different adapter with your laptop.
      
3. Check for Error Codes:
   • Count the number of blinks or monitor any pattern; they may correspond to specific error codes indicated in HP support documentation for your model.
      
4. BIOS Update:
   • Even if you’ve updated the BIOS: HP Envy x360 Laptop 14-es0xxx (9H8Y0U8) Software and Driver Downloads | HP® Support, verify that it was successful by consulting the system’s diagnostics or the BIOS setup utility.
      
5. HP Diagnostic Tools:
   • Use HP Hardware Diagnostics (preboot) to check for any hardware issues: HP PC Hardware Diagnostics | HP® Support. Access it by pressing the Esc key during startup to access the boot menu, and then press F2 to launch diagnostics.
      
6. Test in Safe Mode:
   • Attempt to boot into Safe Mode to see if the issue persists. This will help identify if a software issue might be causing the problem.

I hope this helps.

Take care and have an amazing day!
