ENABLE_LAPTOP_MODE=true

2.修改 /etc/laptop-mode/laptop-mode.conf

交流电模式下使用 laptop mode
#
# Enable laptop mode when on AC power.
#
ENABLE_LAPTOP_MODE_ON_AC=1
＃电池那也可设为1

使用 laptop mode 进行LCD亮度控制
#
# Should laptop mode tools control LCD brightness?
#
CONTROL_BRIGHTNESS=1

#
# Commands to execute to set the brightness on your LCD
#
BATT_BRIGHTNESS_COMMAND="echo 0"
LM_AC_BRIGHTNESS_COMMAND="echo 9" 
NOLM_AC_BRIGHTNESS_COMMAND="echo 9"
BRIGHTNESS_OUTPUT="/sys/class/backlight/acpi_video1/brightness"

如果你不明白上面的设置的意思，可以参考下面的说明

＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
# * If your system has the file "/proc/acpi/video/VID/LCD/brightness" (VID may
# be VID1 or similar), use this file as BRIGHTNESS_OUTPUT, and use
# the command "echo <value>". The possible values can be listed using the
# command:
#
# cat /proc/acpi/video/VID/LCD/brightness

# * If you have a file /sys/class/backlight/.../brightness, then you can use
# that file as BRIGHTNESS_OUTPUT, and the command "echo <value>".
#
# As far as I understand it the values are between 0 and
# the value contained in the file /sys/class/backlight/.../max_brightness.

笑话，这只是愤青们发泄的方式。

国货有好的，也有坏的。 老百姓挣点钱不容易，如果国货质次价高，我们为什么要买？为什么不能买高性价比的日本货？如果国货质优价低，我们当然会买。过去的永久自行车，现在的海尔家电不都很受欢迎吗？

别拿韩国人只买韩国车说事儿了。韩国车在世界汽车工业上就是个笑话，质量太次。看看吧，韩国汽车工业就是这样被惯坏的，不思进取，不求提高质量，反正有人买。

民族企业醒醒吧，提高自己的产品质量，少干点象奶粉一样，无耻又自毁的事情。

我们买商品不是因为所谓的“爱国”，而是它真的值得购买。

今天终于找到了linux下的降温办法，

1. 开启省电模式:

sudo iwconfig wlan0 power on 

2. 降低工作频率到最低档：

su 

echo 1 > /sys/bus/pci/drivers/iwl4965/*/power_level 

设置完后，热度明显降低了，完全温了，很牛。  

删除注册表项:HKLM\software\microsoft\command processor "AutoRun"=c:\windows\system3\sichost.exe
就可以了. 

HTML端代码就更简单。

$.getJSON("http://xxx.com?callback=?",
        function(data){
            alert(data.name);
        }
});

到此，ajax的跨域操作就完成了。网上关于这方面的资料不多，而且都不详细。
上面是我用firebug跟踪HttpResponse,HttpRequest的参数的总结的。
可能有理解不当，或者有更好的方法，欢迎大家一起交流。

 可以定制，这一点比265好。但是速度明显比265慢一些。
