笔记本电脑,想必是大家都熟悉的工具之一,在工作上,学习过程中,笔记本都可以使用的到,一般来讲,在人们的心中,电脑都属于低耗电量产品,那么笔记本功耗标准是多少?这个用户都不太了解的吧,下面,小编就给大家介绍笔记本功耗标准是多少。
现在使用笔记本的越来越多了,而笔记本的配件一般都是专门针对低能耗设计的,功率一般是台式机的1/2到1/3之间,甚至更低,上网本的功率就更不用谈了。要知道笔记本功耗影响着电脑的工作效率跟寿命,下面,小编就来跟大家唠唠笔记本功耗标准界定。
笔记本功耗标准是多少
将为大家详细介绍笔记本功耗的标记数据以及实测数据这两个板块的内容。
功率电脑图解-1
每个笔记本的功率都不同,一般都在60W-70W左右,但是实际用不到。笔记本的配件一般都是专 门 针对低能耗设计的,功率一般是台式机的1/2到1/3之间,甚至更低,上网本的功率就更不用谈了。
笔记本电脑功率一般的20W左右,与屏幕大小高度有关,还与CPU有关,比如迅驰二代比一代省电。

笔记本电脑在使用过程中功率的大小也不一,这处决于你在笔记本上所做的操作:是上网还是利用光驱看片,还是在用移动硬盘,还有显示屏亮度,另电脑中还有自动电源管理系统,随时在调整你的功率。
笔记本的功率的算法:如果输出电压16伏,输出电流3.75安,那么笔记本的功率就是16X3.75=60瓦
独显笔记本电脑的功率多是90w左右。

二、笔记本实际功耗又是多少?
就像台式机我们一般都配 300w电源一样,实际上加上 显示器 绝大部分台式机都没超过230w
我们的笔记本使用时远远达不到这个功率……
实际测试……
测试工具:万用 电表 一只,“公牛”排插一个,导线若干, 插头 一个,剥线钳一把,
(笔记本)
明基 S73EG-101变异版一台配置如下:略,配置强:
说明:功率=电压*电流;AC交流电压约等于240V
测量时:屏幕亮度6/7(MAX),无线网卡开启:
测量结果:
功率电脑图解-4
BIOS,自检:功率=48瓦
Windows XP启动:0.12 功率=28.8-38.4瓦
进入XP桌面待机:=24瓦
显卡性能最高待机:=36瓦
魔兽世界窗口模式:=52.8瓦
功率电脑图解-5
魔兽世界全屏模式:=60瓦
关机:=2.88瓦(没错!笔记本关机也耗电)
充电功率:15瓦
这是机器交流电模式下的功耗
(台式机)
这台台式机CPU性能只有笔记本的70%;显卡性能只有笔记本的20%;魔兽世界里面帧数(fps)只有笔记本的 25%
测试结果:
主机待机:0.8A=192瓦(晕死的奔腾四!!!)
功率电脑图解-6
17寸CRT显示器:0.3A=72瓦
主机魔兽世界:1.1A=264瓦
也就是说,待机状态,笔记本功率一般是多少瓦的,实际功率又是多少?只有台式机的十分之一。
游戏状态,笔记本功率一般是多少瓦的,实际功率又是多少?只有台式机的五分之一左右
另外:台机的耗电大概是4-5个小时一度电吧
我们笔记本的电脑的大概是20-25个小时一度,所以很省的。
功率电脑图解-7
以上就是笔记本功耗标准的解说了。
