张贴在2007年3月18日在1:10 pm

如果您的膝上计算机是力量肉猪，如矿和您比1小时不可能有它前长，有您能做使电池为时更长的有些事。如果您需要作为扩展周期使用计算机时间和，这些技巧是特别有用的备用方式和所有设置在力量计划对话之下(例如关闭硬盘或关闭显示器)真正地不会帮助您，因为一切需要打开!

这在膝上计算机占去大多数力量的主要元件：

1. 硬盘
2. 膝上计算机 Dislplay
3. CD/DVD驱动
4. 网卡
5. 调制解调器
6. 磁盘驱动器

这些技巧将是最有效的，如果您在使用计划您的计算机做某事您不需要连接到的地方互联网或使用您的CD/DVD驱动。如果您是正义文字每纸或创造PowerPoint介绍，则您能最扩大您的电池功率。因为所有这些设备用尽力量，最佳的方式保存力量将简单让他们厌恶!

我们首先开始以显示。如果您在电池跑，您需要确定您的显示跑在最低的亮光。除非您不可能站立它，减少亮光在屏幕将帮助得很多延长电池寿命。几乎所有膝上计算机有一套按钮，通常横跨功能键(F1-F12)那看似小的太阳与一个上上下下箭头在星期日旁边。您按 Fn 锁上位于关键垫的左下角落并且使它保持向下然后压下箭头减少亮光。

什么按钮应该看似

要做的下件事是使不是需要的所有组分失去能力。您能失去能力组分通过进入控制板设备管理程序和做它那里。然而，如果您做它这样，您导致必须继续反复去重新授权给零件，当您需要他们时。一个更好的方式将创造什么称一外形将有所有您的组分使能的硬件配置文件，当您起动您的计算机时，并且另一外形将有失去能力的某些组分，因此挽救力量，当膝上计算机打开时。

一旦您创造第二个硬件配置文件，您重新开始您的计算机并且选择新的外形，去控制板并且使不是需要的一切失去能力并且关闭计算机。 Now when you turn on your computer, you’ll be given the option to choose which profile you want to load, so when you’re on the go with battery power, choose your power conserving profile and when you’re in the office or home, choose the default profile.

How to create a new hardware profile on Windows XP

1. Go to Start, Control Panel, and click on System. If you don’t see System, click on Switch to Classic View at the top left of the Control Panel screen. Click on the Hardware tab and then click Hardware Profiles.

On the next dialog, you’ll see the list of available hardware profiles, which should only contain one item called Profile 1 (Current). This is the default profile that is loaded by default every time you start Windows. Once you add a second profile, the next time you restart windows, you’ll be presented with the option to choose a profile.

In order to create a new hardware profile, go ahead and click Copy. This will copy the default profile, which we’ll be able to modify later on. Next give your profile a name, something like Power Conservation so you know what it is.

Click Ok. You have to option of changing how Windows will ask you about the profiles when you start up your computer, either by waiting until you pick one, or just choosing the default one after 30 seconds. It’s better to choose the second option otherwise your computer will just sit there waiting for you if you don’t pick anything for some reason.

Now you’ll see the new profile in the list of available hardware profiles. Now click on the new profile and click Properties. Choose “This is a portable computer” and choose whether or not it is docked. Also, make sure to check “Always include this profile as an option when Windows starts“.

Now restart your computer and choose the new Power Conservation profile. This will be considered the “current” profile since you chose that one to start up Windows. Once you login, you go to Start, Control Panel, System and click on the Hardware Tab again. This time click on Device Manager.

You’ll see a list of Devices that are currently installed on your computer. You’re going to want to go through and disable anything you don’t need. Now you need to be careful here and not disable something important or else your computer may not work!

You can be safe with disabling Bluetooth devices, DVD/CD ROM Drives, Modems, Network adapters, and Universal Serial Bus controllers. Don’t mess with anything else such as Disk Drives, SCSI and RAID controllers, Processors, System Devices, Displays, or Computers. In order to remove these devices from the “current” hardware profile (the new one you just created on logged on with), right click on a device and go to Properties. Do not choose Disable from this menu! This will disable the item altogether, regardless of hardware profile.

At the bottom, you’ll see a drop down menu under the heading Device usage. This is where you can tell Windows whether or not you want this device to be enabled for a particular hardware profile. Choose Do not use this device in the current hardware profile (disable). Now your device is disabled just for this particular profile. Go ahead and do that for the rest of the devices. If you plan on using something like your USB stick or CD ROM drive, then leave those enabled.

Now simply restart your computer and pick the profile you would like to start with. The devices that are disabled will not use any power or system resources and will increase the life of your battery!

Use Vista Battery Saver to increase the battery life of your Vista laptop Says:

[…] What Vista Battery Saver basically does is disable the Aero interface and turn off the Vista Sidebar. You can also gain more battery power from your laptop if you disable Bluetooth adapter, turn off the CD/DVD drive, disable the modem, disable the network card, disable the sound card, disable the wireless card, and turn off the smart card reader. The more things you disable, the longer the battery life! Here’s an article I had written earlier on how to create power profiles in XP to save battery power. […]
