108 Troubleshooting Your System
Troubleshooting the System Battery
Problem
• System message indicates a problem with the battery.
• System Setup program loses system configuration information.
• System date and time do not remain current.
NOTE: If the system is turned off for long periods of time (for weeks or months), the NVRAM may lose its system
configuration information. This situation is caused by a defective battery.
Action
1
Re-enter the time and date through the System Setup program. See "Using the System Setup Program"
on page 33.
2
Turn off the system and disconnect it from the electrical outlet for at least one hour.
3
Reconnect the system to the electrical outlet and turn on the system.
4
Enter the System Setup program.
If the date and time are not correct in the System Setup program, replace the battery. See "Replacing
the System Battery" on page 75.
If the problem is not resolved by replacing the battery,
see "Getting Help" on page 131.
NOTE: Some software may cause the system time to speed up or slow down. If the system seems to operate
normally except for the time kept in the System Setup program, the problem may be caused by software rather than
by a defective battery.
Troubleshooting the Power Supply
Problem
• Power button is blinking green, but system does not power up.
Action
1
Check the power cable connections to connectors PWR1, PWR2, and PWR CTRL on the system
board. See Figure 6-2.
2
Swap the faulty power supply with a new power supply. See "Removing the Power Supply" on page 50
and "Installing the Power Supply" on page 51.
If the problem is not resolved, see "Getting Help" on page 131.
