All in One won´t turn on

HP Recommended
Pavillion all in one touch
Microsoft Windows 8.1 (64-bit)


The problem is that my All in One, won't turn on. There is no led or visual indications of error, it just simply doesn't turn on. No sound of hardware parts trying to turn on or anything. The only signal I get is the power adapter beeping constantly when connected to the pc (doesn't beep when connected to power, only when connected to power and the pc). I bought a new one thinking that the adapter was faulty, but it made no difference. I've tried all the troubleshooting from the hp support page, but nothing works (holding down the power button for 15 secs with disconnected device, etc..). Is there something else to try? According to this site, my warranty has expired so, I'd like to know if there is something I've not tried yet before directly to the HP shop here in my city. 


I hope there's something I can do, let me know if there is something else you need to know.
