Hello. I've boought a new hybrid hard disk (Momentus XT 7200) and i've replaced the one from my macbook pro with it. Everything seemed fine for one week, but, after that, i've started having problems. They started(maybe coincidence, maybe not) from the moment when i connected my laptop to the TV( via MiniDisplayPort to HDMI adapter). When I first start the laptop, it doesn't boot, it simply remains at the white screen from the beginning. If I close it and reopen it for several times, it starts booting.If I close it after being opened for some time and try to open it again, it boots. The problem appears only if I close it and let it like this for some hours. I'd like to mention that I have two partition: the Mac OS X 10.8.2 one and the Windows 7 via Bootcamp one. I could really use some help, every idea is good. Thank you very much !
