【Vista之家原创】借助老外小软件,为vista的笔记本省电

今天上网，发现了一个老外的创意小程序，程序大小16K，号称可以给Windows Vista省电。根据原文简译了下它的介绍，原理大概就是驻留内存检测电源情况，如果为电池供电则自动关闭Aero，如果来电了就自动把Aero打开，对于笔记本用户来说这样的程序能给电池续航带来不少帮助。

大家感兴趣的话可以下载来试用一下，或者会带给你意想不到的效果！

I get a bit irked when I see stuff that can be solved but people just complain about it. News.com, slashdot, zdnet … list goes on and on about people jumping on the bandwagon. So you know what, I attempted to fix it.

Ok, here is my solution. I spent more time prepping this post than writing the application. Two source materials are a coding 4 fun post by Arian Kulp that handled the power management and a MSDN magazine article by Ron Fosner.

源代码：

using System;
using System.Runtime.InteropServices;
using System.Windows.Forms;
	
using Microsoft.Win32;
	
namespace VistaLaptopBatterySaver
{
    public partial class Form1 : Form
    {

        [DllImport(“dwmapi.dll”, PreserveSig = false)]
        public static extern void DwmEnableComposition(bool bEnable);
	
        [DllImport(“dwmapi.dll”, PreserveSig = false)]
        public static extern bool DwmIsCompositionEnabled();
	
        public Form1()
        {
            InitializeComponent();
            enableToolStripMenuItem.Checked = DwmIsCompositionEnabled();
        }
	
        private void Form1_Load(object sender, EventArgs e)
        {
            SystemEvents.PowerModeChanged += new PowerModeChangedEventHandler(SystemEvents_PowerModeChanged);
            UpdatePowerInfo();
        }
	
        private void SystemEvents_PowerModeChanged(object sender, PowerModeChangedEventArgs e)
        {
            UpdatePowerInfo();
        }
	
        private void UpdatePowerInfo()
        {
            if (enableToolStripMenuItem.Checked)
            {
                PowerStatus ps = SystemInformation.PowerStatus;
	
                DwmEnableComposition((ps.PowerLineStatus == PowerLineStatus.Online));
            }
        }
	
        private void enableToolStripMenuItem_CheckStateChanged(object sender, EventArgs e)
        {
            UpdatePowerInfo();
        }
	
        private void exitToolStripMenuItem_Click(object sender, EventArgs e)
        {
            Close();
        }
	
        private static void aboutToolStripMenuItem_Click(object sender, EventArgs e)
        {
            AboutBox ab = new AboutBox();
            ab.Show();
        }
    }
}
