Probable Solution

1. There is no power in the system.

Power LED does not shine; the

fan of the power supply does not

work

2. Indicator light on keyboard does

not shine.

1. Make sure power cable is

securely plugged in.

2. Replace cable.

3. Contact technical support.

and hard drives are running.

Using even pressure on both ends of

the DIMM, press down firmly until the

module snaps into place.

drive, but can be booted from optical

drive.

1. Check cable running from disk to

disk controller board. Make sure

in; check the drive type in the

standard CMOS setup.

2. Backing up the hard drive is

extremely important. All hard

disks are capable of breaking

drive. Hard disks can be read,

fails to boot from a hard disk.

1. Back up data and applications

files.

2. Reformat the hard drive.

Re-install applications and data

using backup disks.

Configuration” or “CMOS Failure.”

Review system’s equipment. Make sure

correct information is in setup.

second hard drive.
