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....
Antwort auf „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
