Figure 6- 19: Accessing the internal parts
Refer to Figure 6--19 and locate the SODIMM (RAM) module on the controller
board. To remove the memory, press outward on the clips holding each SO-
DIMM module to the controller board, and then lift off the module board.
CAUTION.
SODIMM modules must have gold plated contacts.
Use of SODIMM modules that do not have gold plated contacts will result in
eventual failure of the SODIMM module.
To install the memory, insert the new SODIMM module. Press down gently until
the clips that hold the modules to the controller board snap into place.
Refer to Figure 6--19 and locate the 3 V lithium battery on the controller board.
Remove the battery from the clip by using a small tool and prying the battery
until it pops out of the clip.
