Information

To use Apple Hardware Test: Disconnect all external devices
from your computer, except the display, keyboard, and
mouse. If you have an Ethernet cable connected, disconnect
it. Restart your computer while holding down the D key.
When the AHT chooser screen appears, select the language
for your location. Press the Return key or click the right arrow
button. When the AHT main screen appears (after about 45
seconds), follow the onscreen instructions. If AHT detects a
problem, it displays an error code. Make a note of the error
code before pursuing support options. If AHT doesn’t detect
a hardware failure, the problem might be software related.
Important: If Apple Hardware Test doesn’t appear after
restarting, hold down the Command (x), Option, and D keys
and restart the computer to access Apple Hardware Test from
the Internet. Be sure to reconnect your Ethernet cable. Your
computer must be connected to a network that has access
to the Internet.

Display
Arrange the display so that the top of the screen is slightly
below eye level when you’re sitting at the keyboard. The best
distance from your eyes to the screen is up to you, although
most people seem to prefer 18 to 28 inches (45 to 70 cm).
Position the display to minimize glare and reections on
the screen from overhead lights and nearby windows.
The stand lets you set the display at the best angle for
viewing, helping to reduce or eliminate glare from lighting
sources you can’t move.
