The sad face was added to the windows BSOD in Windows 8 and above.
If you don't even see the POST screen (or HP Logo) when you turn it on, then something is wrong with the hardware. The hardware fault might have caused an error when booting the time you saw the BSOD screen, so the details of that error could help you narrow it down.
To start with, try removing the battery and leaving the system unplugged for about 5 minutes. Then, see if it will attempt to boot after that and be ready with your camera to take a picture of what that sad, blue screen says.
