Protecting Against Static Electricity
STATIC WARNING: Before handling any of the components in the
notebook, take precautions against damage caused by static
electricity on your body.
If you have an earthing wristband, attach it to the power supply
unit. Make sure that it is connected to a metal part of the power
supply unit and not to a label.
If you are using an earthing wristband with a crocodile clip, attach it
to an unpainted section on the rear panel.
If you do not have an earthing wristband, always discharge any
static electricity which may have built up on your body before
touching any components. To do this, touch the unpainted metal
rear panel of the notebook near the mains inlet.
If you take a break from working inside the notebook, repeat the
above procedure before you restart. You need to discharge new
static, which may have built up on your body.
3.1: Fitting Hardware Options
DIMMs
Your notebook may use Dual In-line Memory Modules (DIMM) to
provide random access memory (RAM).
All RM Mobile One 945 notebooks are supplied with a minimum
128MB of RAM. The system board in your notebook can be
upgraded using the additional sockets available.
Depending on the model, there may be a number of DIMM sockets
on the system board. Memory modules can be fitted in these
sockets in certain arrangements only. Do not use other
combinations. If you do so, your notebook may not operate
correctly.
The different memory module combinations and sockets are
specific to each model of RM notebook. Refer to the System Board
User’s manual (if supplied) or contact RM for details of allowed
combinations.
