2 month old Chromebook plus 15a-nb won't power on

[Tooltime2]

My 2 month old Chromebook plus 15a-nb won't power on after charging overnight.

Was working fine the day before but now it won't startup.

Have let it charge over another night and even swapped out chargers from an old HP laptop to see if that was the fault.

Tried 2 different hard resets as per what I could find on HP troubleshooting, but that didn't work.

Won't boot up (start up) plugged in or not. Yes the power supply is the one that came with the laptop.

I am at a loss, and of course I need it urgently and no one is available as it is outside of office hours.

Can someone please help?

Thank you..

Hi @Tooltime2, Welcome to HP Support Community. 

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

Since your HP Chromebook 15a-nb is not power on even after troubleshooting, it could be a battery, power circuit, or firmware-related issue. Try the following steps:
 

Check for Any Power Indications

• Plug in the original charger and check if the charging LED turns on.
• If the LED does not light up, try a different power outlet.
• If the LED blinks, note the blinking pattern as it may indicate an error code.

Perform a Hard Reset Again

Try the following hard reset methods (even if you've done them before):

Basic Hard Reset

• Hold the Refresh (↻) + Power button together for at least 10 seconds.
• Release the buttons and try turning it on.

EC (Embedded Controller) Reset

• Unplug the charger.
• Press and hold Esc + Refresh (↻) + Power for at least 15 seconds.
• Release all buttons and try powering it on.

Try Recovery Mode

• Press and hold Esc + Refresh (↻) and then tap the Power button.
• Release the Power button but keep holding Esc + Refresh until a recovery screen appears.
• If you see the recovery screen, follow the on-screen instructions to reinstall ChromeOS.

Check for Static Charge Issues

• Unplug the charger.
• Hold down the Power button for 30 seconds.
• Leave the Chromebook unplugged for 30 minutes.
• Try turning it on again.

I hope this helps. 

Take care and have a good day.

Thanks get your help Max. 
It has been “resolved” as far as your explanation and help, so thank you for that. 

The laptop has been sent back to place of purchase and I’m awaiting their response (and diagnosis) as to what to do from there and hopefully the cause of the malfunction. 
I can keep you updated on the outcome if it helps you and the community. Please let me know.
