HP Spectre x360 Won’t power on

[Aurora10]

Hi all,

one day it’s working fine; the next’ nothing.

When I plug my laptop into its charger the amber charging LED illuminates’ then it shuts off about 10 seconds later. Same goes for the power button.

When I turn it on the laptop shows blank/black screen and then displays the HP logo for 0.5 seconds before it dies and power is lost. The laptop doesn’t even get a chance to boot up the fans or make a beep; just dies, then it tries again. I’ve tried the CMOS reset’ and by attemption to get to the BIOS menu’ which was successful’ the BIOS screen displayed instead of the HP logo’ but again that was short lived and the laptop died within half a second of showing the BIOS page.

This occurs even when the internal battery is removed.

I've re-tightened every internal connection with no luck; I’m leaning towards it being a fried system board.

Does anyone have any suggestions?

and if it is the board’ where can I find a replacement specific to my laptop from HP?

I believe my motherboard is toast. Any suggestions?
