Lenovo y40-70 wont turn on

I have a lenovo Y40-70 that i received from a friend and im trying to fix, so the laptops power button lights up after you press it for about 3 seconds, but no fans or hard drives, keyboard, anything, nothing turns on besides the power button LED, heres what i've tried.

  • Disconnecting the battery and turning it on using ac adapter
  • Disconnecting CMOS battery and letting it drain to turn on
  • Plugging in bootable USB
  • replacing the ram
  • Made sure that all of the visible connectors inside the laptop were plugged in
  • Presssing the small button next to the power button
  • Plugging in an external monitor and powering on

I was wondering that someone online could help me fix the issue or get it to at least get into the bios, i've tried everthing i can think of so far. let me know what you guys think.
