Hello people, Well this is my first post, I´m glad to join to this community. This is my problem: I have a Macbook 15" Mid-2009 Unibody which was working really well, then my hdd died so I changed it and turned it on.. The only I got was the CHIME sound and white screen. There's not icon folder or anything. Here's what I've tried: 1. I tried to boot into recovery or boot manager but I couldnt because my keyboard doesn't recognize any command 2. I tried to reset NVRAM, PRAM and SMC but I couldnt because my keyboard doesn't recognize any command 3. Tried another pair of RAM 4. Tried another HDD with a working installation of MAC OS X 5. I tried an external monitor but nothing happens, all I get is CHIME and white screen on my macbook 6. I left it on for hours but stays in white screen 7. I tried to start with an external HDD mac os x installation 8. I tried to use a usb keybord but doesn't work I noted that the fancooler is working really fast (more than normal). Thank you very much for any help you could give me.
