Subtest 10 Temperature surveillance test
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 37, the CPU temperature is 37
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 more
than or equal to 70 degrees, the computer fails the test, and an error message
appears on the display.
Subtest 11 BT/W-LAN Switch test
Check if ON/OFF of the BT/W-LAN switch is correct.
Subtest 12 Battery F/W test
The subtest displays the following message and read the date written in the battery
and check if the battery is correct
* Get ! Battery date *
Battery type = XXXXXXXXXX
NG: Compare error
OK: Returns.
This subtest is for G71C0000H310 and G71C0000H410.
Subtest 13 Optional battery F/W test
This subtest checks option batteries in the same way as Subtest 12.
This subtest is for optional batteries (G71C0002J110 and G71C0002J210).
