Question

Menu ALT

Jul 15, 2011 6:44PM PDT

ALT menu allows it to conclude that a failure.

For example, I have a gray spot on the screen of my iMac or my MacBook. I reset SMC and ZAPPRAM, I start on the menu ALT and the task is still there?
Are what we can conclude that a hardware failure.

Another example, on a MacBook, the latest generation, clicking the track pad does not work. SMC ZAPPRAM, starting ALT and click does not work.
Are what we can conclude that a hardware failure.
