varalu 0 Report post Posted January 3, 2008 I know this is very much known to many people. I recently stumbled upon this on Vista documentation and thought it will be of some use to others... Get the most from a single chargeIf you have time to do only one thing... Use the Power saver power plan to minimize power consumption. You can always return to this article later to try more power-saving tips. To choose the Power saver plan, open Power Options in Control Panel.Ever run out of battery power in the middle of a meeting? Has the urgent beep of your mobile PC's battery alarm made you the center of attention during an executive presentation? Even with recent advancements in battery cell technology and in software that makes efficient use of power, you can do only so much work on a single charge. The trick is to get the most out of the power that's available.Chances are, you already have ways to make sure your mobile PC has power no matter where you are. Maybe you always carry the power cord or an extra battery for times when AC power isn't available. Those strategies work, but do you know how to get the most out of the battery youll be using during your next five-hour flight?Here are a few easy tips that can help you stretch your battery's power:Choose a power plan that saves power. A power plan is a collection of hardware and system settings that control how your mobile PC manages power. These settings include power-saving measures, such as switching to a power-saving state when you aren't using your mobile PC.Reduce display brightness. The display can use more power than any other computer hardwareeven more than your hard disk and CPU. Although many mobile PCs are equipped with keys to adjust brightness and other display settings, the way you change the display brightness can differ depending on the mobile PC manufacturer. To learn more about how to dim your display, check the information that came with your mobile PC or go to the manufacturer's website.Shorten the length of time before Windows turns off the display. When you're not using the mobile PC even for brief periods of time you can save power by having Windows turn off the display after a brief period of inactivity.On the Select a power plan page, in the task pane, click Choose when to turn off the display.On the Change settings for the plan page, next to Turn off the display, choose the display and sleep settings that you want to use when your mobile PC is running on battery and when it's plugged in.Click Save changes.Turn off or remove devices that you aren't using. Many universal serial bus (USB) devices use power just by being connected. If you use a USB mouse, you can save power by disconnecting the mouse and using a touch pad or tablet pen. If you use a USB flash drive, unplug it when you're not using it.Personal Computer Memory Card International Association (PCMCIA) cards and integrated wireless devices also use power. If you don't need these devices while you work, turn them off.These power-saving tips can help you get the most use from a single battery charge and avoid the inconvenienceand the potential embarrassmentof having a dead battery.

t3jem 0 Report post Posted January 3, 2008 These are great tips, I already use them, but I know many people who don't and then complain about lack of battery. Another great tip is not to start charging your battery until the batter is dead or almost dead, this will keep the battery reliable for longer periods of time. When you charge the batter from 50% many times then the lifespan of the battery is shortened alot quicker and you won't be able to use the battery as much.
