Windows saves power
Windows uses the power saving features of current mobile processors like the Pentium M Speed Step Enhanced Power Now and the Mobile Athlon 64 and Turion 64 – unless you set the appropriate power scheme. Then adjusts the processor’s clock speed and supply voltage dynamically to the load – it draws strongly on the gd761 battery only when there is something to do really something.
The power scheme, see “Control Panel, Power Options. The ideal setting is “Portable / Laptop”: Then the processor behaves both network-and power-saving inspiron 6400 battery power. When set to “continuous use” on battery also fits the CPU clock speed and voltage to – but not in operation: He always runs at the fastest settings – then the fan is usually in the disturbing long-term use.
Permanent with the lowest clock speed and voltage of the processor works in the settings of “presentation” and “Max Battery”,such as thinkpad z61p battery – the current Pentium M and Turion 64 running, for example, then even under load at 800 MHz. The difference between the two power schemes: By default, the monitor turns on “presentation” from before.
This speed brake is only worth considering if you move it is sufficient to lower performance when you write for example, only texts. For the CPU consumes lower power with the clock speed and voltage but less power of thinkpad z61e battery, but works more slowly – so you need more time to perform a specific task: the savings of the CPU is eaten up by again.
Some laptops slow on thinkpad t40 battery ower in any case the CPU – no matter what power scheme you set: The “people Notebook Amilo A7645 Fujitsu-Siemens, for example, slows down the Turion 64 permanently to 800 MHz. Watching DVDs and Divx movies, or TV over DVB-T makes it no fun anymore. If your notebook even such a brake, take a look at the bios: You may find an option that you can once again help the CPU at full speed – the “people’s notebook” search in vain.
The frequency of your processor you read, for example with the tool Everest Home 2.0 from: You can find the current clock speed in the menu “Computer, Overclock” under “CPU speed.
