Wireless turns off and will not turn on without a restart.Works great EXCEPT at least 1x or 2x per day it turns off. If I reset NVRAM it usually works again. It is not about heat....
Respuesta a "Installed new battery, computer turn on,display is black, please help!"after you turn it on long enough to have it start, try hitting the F2 key 5 or 10 times. If you are really lucky it just might work. Jim in Chicago
