HARDWARE MONITORING
(optional)
GL518SM (U4) is designed on the board to monitor hardware healthy status like
system voltage, system temperature, and cooling fans. When the CPU is over
heated, the system BIOS will tell the system board to give a series of beeping alarm
and then slow down the CPU speed so that you can take proper action to prevent
damage to your system. When you hear the beeping alarm, be sure to turn the power
off and open the chassis immediately, check on the cooling fans (especially the
CPU cooling fan ) to see whether it is working properly or not. If you don’t know
how to handle it, send the PC system to your dealer for technical support.
