2. PC power management - Wikipedia

   en.wikipedia.org/wiki/PC_power_management

   The Windows power management system is based upon an idle timer. If the computer is idle for longer than the pre-set time, then the PC may be configured to sleep or 'hibernate'. Windows uses a combination of user activity and CPU activity to determine when the computer is idle.

3. Kill A Watt - Wikipedia

   en.wikipedia.org/wiki/Kill_A_Watt

   The Tweet-a-watt [13] is a hacked version of the standard Kill-A-Watt Plug in Power Meter. By piggybacking on the device's on-board LM2902N op-amp chip, the creator was able to get readings for voltage and current and transmit to a computer, which then sent this to Twitter via handle @tweetawatt.

4. PowerTOP - Wikipedia

   en.wikipedia.org/wiki/PowerTOP

   PowerTOP is a software utility designed to measure, explain and minimise a computer's electrical power consumption. [1] It was released by Intel in 2007 under the GPLv2 license. It works for Intel, AMD, ARM and UltraSPARC processors.

5. Power supply unit (computer) - Wikipedia

   en.wikipedia.org/wiki/Power_supply_unit_(computer)

   The system power consumption is a sum of the power ratings for all of the components of the computer system that draw on the power supply. Some graphics cards (especially multiple cards) and large groups of hard drives can place very heavy demands on the 12 V lines of the PSU, and for these loads, the PSU's 12 V rating is crucial.

6. Power Management Unit - Wikipedia

   en.wikipedia.org/wiki/Power_Management_Unit

   The Power Management Unit (PMU) is a microcontroller that governs power functions of digital platforms. This microchip has many similar components to the average computer, including firmware and software, memory, a CPU, input/output functions, timers to measure intervals of time, and analog to digital converters to measure the voltages of the main battery or power source of the computer.

7. Power management - Wikipedia

   en.wikipedia.org/wiki/Power_management

   The power management for microprocessors can be done over the whole processor, or in specific components, such as cache memory and main memory. With dynamic voltage scaling and dynamic frequency scaling, the CPU core voltage, clock rate, or both, can be altered to decrease power consumption at the price of potentially lower performance. This is ...

9. Standby power - Wikipedia

   en.wikipedia.org/wiki/Standby_power

   Standby power consumption of some computers can be reduced by turning off components that use power in standby mode. For instance, disabling Wake-on-LAN (WoL), [32] "wake on modem", "wake on keyboard" or "wake on USB" may reduce power when in standby. Unused features may be disabled in the computer's BIOS setup to save power.
