Hi i have Hp Spectre x360 laptop and i was using it 3 hours ago and it showed 20% battery and then it turned off after sometime i thought the battery died so after sometime i plugged it back in and when charging light turned white i tried to turn it on and i stayed off. So i unplugged charger and held power button for 30 secs and then pressed power button again and this time the power button light up but laptop still stayed off. I cannot hear CPU fan or HDD sound and Disk activity light is also off. the power button stays light up but nothing else happens.
 
First step, check if it's in warranty, if it is contact HP.

If it's not, it's likely the motherboard is dead and you need a new one. Try re-seating the RAM and drive, try again. Also see if that system has a CMOS battery you can remove, in that case you would have to open it, remove the CMOS battery main battery and try holding the power button again for a bit, then see if it turns on.
