Point to note about memory module error

If you install a memory module that is not compatible with the computer, the Power indicator will flashes (on for 0.5 seconds, off for 0.5 seconds) in the following ways;

■If there is an error in only Slot A or no memory module is inserted in Slot A: repeatedly flashes orange twice, then green.

■If there is an error in Slot B: repeatedly flashes orange, then green twice.

■If there are errors in both Slot A and Slot B: repeatedly flashes orange twice, then green twice.

In all instances you should shut down the computer and remove the incompatible module(s).

Use a point size 0 Phillips screwdriver to remove and fasten the screws - the use of an incorrect screwdriver can damage the screw heads.
