Windows 10: Why is the power button blinking light

The power button on my laptop keeps blinking and I'm getting no power however I haven't plugged into the charger and it is indicating that it is charged and the power light on the other side of the laptop is also on indicating that there should be power but Getting atype of home screen or anything like that please help

:)

 

Press the Start button, blue power light blinks once, accessory lights blink once then nothing

I have a HP Elitebook 8740W running Win 10 Pro. When I press the start button the power light on the front of the laptop comes on for 2 seconds, then the accessory lights across the top of the keyboard blinks once, then nothing happens. The screen is blank.
If I hold the Start button down, the power light stays on for about 9 seconds then the accessory lights blink and then the screen is blank.

I have removed the battery and power wire, then held down the Start button for 30 seconds. Put the battery back in and the power plug. No change is anything.

The power light does not come on when the laptop is plugged in.

Any ideas on what to do now.

 

Power Light blinks before Shutting Down

I thought the same thing. My PC does that.. red light blinks until it's fully shut down.

 

Power Light blinks before Shutting Down


I thought it was normal for the activity light to continue to blink until its actually off as its doing the shutdown sequence. Also you don't need to sign out before shutting down. Just one less step to do *Biggrin
