HP Pavilion X2 12 charge indicator blinking orange/white

[CTse26]

There when I put the charging cable into the tablet, the indicator goes orange then blinks after 2-3 seconds. Thinking it may be a battery issue, I did the following:
1. Removed the front LCD panel
2. Disconnected the battery
3.Held on to power button to discharge the remaining power.

When I replugged the charger into the tablet with the battery disconnected, the indicator would be white, and blinks every 2-3 seconds.

Could it be a mother board issue? Im really hoping it isn't 😕

Also I forgot to mention, it does output a high frequency sound every few seconds as if trying to boot repeatedly when on battery without the light indicator on.

I recounted the seconds and it blinks about every 10 seconds

Welcome to the HP Forums 🙂 

I would like to take a moment and thank you for using this forum, it is a great place to find answers. 

As I understand the charger light is blinking about every 10 seconds,

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details: 

Did you attempt to first plug in the wall outlet and then in the laptop to check if it works?

Did you check with an alternate wall outlet or adapter?

While you respond to that, here's what I recommend:

 For the battery light blinking repeatedly, I have included the following document 'Computer Does Not Start and the LEDs Blink or the Computer Beeps', Once you do have the link open, click on Battery power LED blinks' and follow through the steps.

The best way to do that is using the HP Guided Troubleshooter:
