MacBook suddenly shut down and will not turn back on.
My MacBook suddenly shut down with about 17% battery left. We tried the shift, control, option, power key buttons and held them down simultaneously for 10 seconds. Then plugged in the power cord and hit the power key. The laptop turned back on. We entered our password to log in and it was loading at the bottom. Then it suddenly shut down again. Now we cannot get it to turn back on at all.
