Chapter 2 • Troubleshooting
Possible Solution
■
Is the Power button for the monitor turned on?
■
Is the monitor power cord connected to a wall outlet?
■
Does the wall outlet have power? Test by connecting another device.
■
Is the monitor connected to the onboard video connector or PCI Express
video connector?
■
Try all of the power-off options described in
on page 30.
■ If the workstation still does not power off, disconnect the power cable from
the back of the chassis.
The Power LED blinks only when all workstation peripherals are in low-power
mode. A tape drive might be connected to your workstation. Because tape drives
do not enter low-power mode, the power LED does not blink.
■
Check the network cabling and equipment to make sure that all cables are
correctly seated.
■ Reinstall the network drivers.
■
Use the DIMM removal and installation procedures in section,
and Installing DIMMs" on page 53

■ Ensure that you are following DIMM rules and using a supported

properly seated. See, "Removing and Installing a Hard Drive" on page
■
Move the mouse or press any key on the keyboard. The drive might be in the
low-power mode.

■
Are you using the correct type of DVD?
■ Do other DVDs work in this drive?
■
Is the DVD properly inserted in the drive?
■ Is the DVD clean and unscratched?
■
Are the cables connected to the DVD drive?
