    AL440LX Motherboard Product Guide Replacing the Battery When your computer is turned off, a lithium battery keeps the time-of-day clock and the values in CMOS RAM current. Figure 12 shows the location of the battery. The battery should last about seven years. When the battery begins to die, it loses voltage; when the voltage drops below a certain level, the Setup program settings stored in CMOS RAM (for example, the date and time) might not be accurate.

    Appropriate protection is provided by a maximum 8-Amp current limiting circuit or a maximum 5- Amp fuse or positive temperature coefficient (PTC) resistor. All Intel motherboards now have PTCs on all external ports that provide DC power externally.

  • Page 59: Prevent Power Supply Overload

    AL440LX Motherboard Product Guide Prevent Power Supply Overload Unless the power supply has inherent overcurrent protection, do not overload the power supply output. To avoid overloading the power supply, make sure that the calculated total current load of all the modules within the computer is less than the output current rating of the power supply. If you do not do this, the power supply could overheat, catch fire, or damage the insulation that separates hazardous AC line circuitry from low-voltage user accessible circuitry.
