Subtest 09 CPU Thirmistor
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.
