Subtest 09 CPU Temperature
This subtest measures the CPU temperature to see if the cooling functions of the
computer are effectively working.
When the subtest starts, the following message appears on the display:
CPU TEMP = XX deg C Throttling level = XXXXh
The number of the CPU TEMP indicates the CPU temperature at the moment in
decimal notation. For example, if the number is 57, the CPU temperature is 57
degrees.
The number of “Throttling level” indicates how much the CPU has slowed. This
number takes one of the following three values:
0000h : The CPU is running full speed.
4000h : The CPU has slowed to 75% of its maximum speed.
8000h : The CPU has slowed to 50% of its maximum speed.
The subtest displays the message five times at intervals of one minute; therefore, it
takes five minutes to complete the test. The computer passes the test if the CPU
temperature is less than 70 degrees at the end of the test. If the temperature is 70
degrees or more, the computer fails the test, and an error message appears on the
display.
