Troubleshooting
If the computer displays a memory error after you have
turned it back on, check the following:
Turn the computer off and unplug the power cord,
then open up the memory compartment and make
sure the memory card is firmly seated. To install it
correctly, make sure it inserted all the way into the
compartment and then push down on it to snap it into
place.
Verify that the memory installed is compatible with this
computer. SO-DIMMs are small outline dual inline
memory modules. They are smaller and thinner than
most other DIMMs, so that they take less space in the
case.
SO-DIMM modules must meet the following
requirements:
200-pin DDR2-DIMM
PC2-4200 (533 MHz) DDR2-SDRAM or PC2-
5300 (667 MHz) DDR2-SDRAM
Unbuffered, non-ECC (64-bit) DIMMs
1.8 V memory only
4.0 GB maximum installable memory. Actual
available memory that can be used in Windows
will be less.
Because the memory uses dual channels, you
should use the same DIMM type for both sockets.
