What have you tried so far?Um, what do i do?
Well... it sounds like it 'powers on' but won't boot.Well it is fully charged and this symbol would appear every time I open my MacBook pro. So I tried powering it off and turning it back on multiple times but the same symbol would appear over and over again. But usually before the symbol shows, a loading bar appears under the apple logo. And no light is shown when the symbol is appeared. Also, as I leave the MacBook pro open with the symbol visible on the screen for a while, it starts to get a bit heated up.

Can you describe the symbol or take a picture?
