Mac only boots into Windows, USB. Shuts off Mac side, and internet recovery.

Hi All,

Yesterday, my Dad cleaned my MacBook Pro, Mid 2012 (13inch) with a damp cloth, and ever since the fan has been going full force, internal keyboard not working (USB does), Battery indercator not working, and, not booting into mac (it did yesterday, but not today.) The mac just shuts off, no warning, just off. I have tried:

Cmd - Shift - R - Internet Recovery (loads the image fully, the apple logo appears and then it shuts down.)

Cmd - R (Just shuts down)

Cmd - D (no problems),

Using option works, selecting an alternate boot device, but only Windows, or a USB not running mac

\

I tried getting a bootable OS X 10.10 USB to work, it loads a bit on the apple logo, then dies.

And, tried resetting the SMC, but i don't tihnk it worked with the internal keybaord not working.

I have booked a appointment with the Genius bar on Monday, just seeing if i can try anything else.

Thanks for your help!
