+ | ===== reduce power consumption ===== | ||
+ | |||
+ | You can't affect how fast the laptop charges, so we will focus on reducing power consumption. | ||
+ | |||
+ | ==== screen brightness ==== | ||
+ | One of the easiest and most effective power saving techniques is to **reduce screen brightness** to a dimmer but still-usable level. | ||
+ | |||
+ | This will make the biggest difference on laptops with larger screens. | ||
+ | |||
+ | |||
+ | ==== tune laptop-specific settings ==== | ||
+ | |||
+ | {{ : | ||
+ | |||
+ | Common settings: | ||
+ | |||
+ | * dim screen after X minutes of inactivity | ||
+ | * blank monitor after X minutes | ||
+ | * suspend/ | ||
+ | |||
+ | Set the timeouts as aggressively as you can stand. | ||
+ | |||
+ | |||
+ | ==== reduce cpu load ==== | ||
+ | {{ : | ||
+ | Extraneous applications running on your laptop consume CPU cycles, which in turn consumes more battery power. | ||
+ | |||
+ | The first place to look is **the System Tray** (see image to the right). | ||
+ | |||
+ | Right-click on each icon in the System Try to see what it is. If t is not necessary disable or uninstall it. | ||
+ | |||
+ | |||
+ | The second place to look is the **Startup folder**. | ||
+ | |||
+ | Navigate to your Startup folder and delete any icons for programs that are not necessary for automatic running. | ||
+ | |||
+ | |||
+ | ==== eliminate cpu-taxing animations ==== | ||
+ | |||
+ | Some webpages have animated or multimedia elements that consume CPU cycles when they are visible. | ||
+ | |||
+ | If you want to allow the animations but not have them consume as much power you can switch to another tab so the animation is no longer rendered. | ||
+ | |||
+ | ==== reduce bandwidth ==== | ||
+ | |||
+ | Reducing bandwidth usage will, in addition to easing the pain on your checkbook, reduce the processing power needed to handle the data. It will also reduce the amount of time the wifi or bluetooth are transmitting. | ||
