半夜听到黄家驹的声音, 忽醒,一身冷汗,哦,原来是计算机忘了关,还在播放Beyond演唱会.于是做了个较简单的自动关机程序 :)
半夜听到黄家驹的声音, 忽醒,一身冷汗,哦,原来是计算机忘了关,还在播放Beyond演唱会.于是做了个较简单的自动关机程序 :) (一).说明
我平时喜欢听几首歌再关机睡觉,夏天还好,冬天光着身子去关机要冻个半死 :(,因此为这事做了个最简单的自动关机程序,读者如果用得着,就下载用一下吧
最近用这个程序爽多了
1. 睡觉之前不用顾虑: '
2.省电. 一天两天忘了关机交电费还撑的住,如果长期下去,一大笔电费咋交得起啊.
就算有钱也不心甘交这冤枉钱,给鬼听啊.
3.夏天跑去关机还好,如果是冬天的话,要冻个半死
4.恐怖啊! 半夜听到<黄家驹>的声音, 忽醒,一身冷汗,原因是计算机忘了关,它还在播放Beyond演唱会
