I have a 2010? MacBook Pro that I would like to use. I bought a cheapo ThunderBolt to HDMI adapter that I planned on using with one of the displays for my windows desktop. Here's the backstory. I bought it brand new. It was dropped. It still booted after it was dropped, but the drop caused the display to shear off, basically. I put it away for some months and took it out at one point to use the harddrive in my desktop for a bit of extra space. This meant it had to be formatted. Today, I received the adapter in the mail. I pop the harddrive back into the Mac, pop the CD into the drive, plug the adapter/hdmi cable in, and I press the power button. Nothing. The light on the MagSafe port is VERY VERY dim green. SMC/NVRAM/PRAM resets do nothing. However, if I bypass the SMC by unplugging the MagSafe, holding power, then plugging the MagSafe back in it will boot. Here's the next issue. Since I'm using the SMC bypass mode, no function keys work. I can't turn the volume up, put the laptop to sleep, or anything. Even closing the lid to put it into clamshell mode won't work. HOWEVER, I can see the default Mac background ( http://i.imgur.com/4pCp0zW.jpg ) on the external display. This leads me to believe the MacBook is on the OSX installer, but trying to work on the laptop display. I can move the mouse onto the screen and everything. Before anyone suggests it, I have tried every hotkey for swapping displays/turning on mirroring/clamshell mode etc. Any help here? I'd like to get back into the habit of using OSX, but my wallet isn't quite ready to buy a new MacBook just yet.
