Note
The end user must determine the cooling preferences for the system by using the setup nodes in the BIOS setup program to establish the
appropriate trip points. If passive cooling is activated and the processor temperature is above the trip point the processor clock is throttled
according to the formula below.
∆P[%] = TC1(T
n
-T
n-1
) + TC2(T
n
-T
t
)
∆P is the performance delta•
T•
t
is the target temperature = critical trip point
The two coefcients TC1 and TC2 and the sampling period TSP are hardware dependent constants. These constants are set to xed values •
for the conga-B915:
TC1= 1•
TC2= 5•
TSP= 5 seconds•
See section 12 of the ACPI Specication 2.0 C for more information about passive cooling.
ACPI Suspend Modes and Resume Events6.5
conga-B915 supports the S1 (POS= Power On Suspend) state and S3 (STR= Suspend to RAM). For more information about S3 wake events
see section 9.4.1 “ACPI Conguration Submenu”.
S4 (Suspend to Disk) is not supported by the BIOS (S4_BIOS) but it is supported by the following operating systems (S4_OS= Hibernate):
Win2K•
WinXP •
