  2. Idle (CPU) - Wikipedia

    en.wikipedia.org/wiki/Idle_(CPU)

    An advantage of the latter approach is that programs monitoring the system status can see the idle task along with all other tasks; [citation needed] an example is Windows NT's System Idle Process. Some programs are designed to appear to make use of CPU idle time, meaning that they run at a low priority (but slightly higher than idle priority ...

  3. System Idle Process - Wikipedia

    en.wikipedia.org/wiki/System_Idle_Process

    However, the idle process does not use up computer resources (even when stated to be running at a high percent). Its CPU time "usage" is a measure of how much CPU time is not being used by other threads. In Windows 2000 and later the threads in the System Idle Process are also used to implement CPU power saving.

  4. Uptime - Wikipedia

    en.wikipedia.org/wiki/Uptime

    The first number is the total number of seconds the system has been up. The second number is how much of that time the machine has spent idle, in seconds. [16] On multi-core systems (and some Linux versions) the second number is the sum of the idle time accumulated by each CPU. [17]

  5. HLT (x86 instruction) - Wikipedia

    en.wikipedia.org/wiki/HLT_(x86_instruction)

    For example, hardware timers send interrupts to the CPU at regular intervals. Most operating systems execute a HLT instruction when there is no immediate work to be done, putting the processor into an idle state. In Windows NT, for example, this instruction is run in the "System Idle Process". On x86 processors, the opcode of HLT is 0xF4.

  6. Underclocking - Wikipedia

    en.wikipedia.org/wiki/Underclocking

    Underclocking, also known as downclocking, is modifying a computer or electronic circuit's timing settings to run at a lower clock rate than is specified. Underclocking is used to reduce a computer's power consumption, increase battery life, reduce heat emission, and it may also increase the system's stability, lifespan/reliability and compatibility.

  7. Processor power dissipation - Wikipedia

    en.wikipedia.org/wiki/Processor_power_dissipation

    In many applications, the CPU and other components are idle much of the time, so idle power contributes significantly to overall system power usage. When the CPU uses power management features to reduce energy use, other components, such as the motherboard and chipset, take up a larger proportion of the computer's energy.

  8. HP Pavilion dv9000 series - Wikipedia

    Windows 7: test on an out-of-box model consisting of a dv9700t-series dv9843cl with slightly upgraded specs, including a 2.6 GHz T9500 processor, 4 GB 800 MHz DDR2 RAM, 512 MB GeForce 8600M GS video graphics adapter, a Samsung 850 EVO 120 GB solid state drive, no external attachments, Wi-Fi enabled, 32-bit operating system, results yielded a ...

  9. Cool'n'Quiet - Wikipedia

    en.wikipedia.org/wiki/Cool'n'Quiet

    In addition to the CPU drivers offered by AMD, several motherboard manufacturers have released software to give the end user more control over the Cool 'n' Quiet feature, as well as the other new features of AMD processors and chipsets. Using these applications, one can even control the CPU voltage explicitly. PhenomMsrTweaker (SourceForge link)
