Shut Down and Open Computer
1. Shut down your UMAX S900. If the computer
has been on for any length of time, wait a few
minutes for it to cool before beginning the
installation.
2. Disconnect the power and peripheral cables
from the back of the computer and move it to
an area where you can freely work.
3. With the rear of the computer facing you, open
your computer by first loosening the security
screw on the back of the case; then, lift the case
cover away from the computer (Figure 1).
4. Gently lay the computer on its side and iden-
tify the internal components of your computer.
Touch the power supply metal shielding
(Figure 2) to discharge any potential damaging
static electricity.
Remove Processor Card
Remove the current processor card from the
Processor Card Slot (Figure 3) and set it aside.
Be careful! The heatsink on top of the processor
card can get extremely hot if it has not been given
sufficient time to cool.
Reset CUDA Switch
Reset the CUDA switch on the logic board
(Figure 4). It is located at the rear of the logic board
near the first PCI slot. Resetting this switch ensures
that a new upgrade card is recognized at the
next startup.
