因为挂起后无法唤醒，所以安装了laptop-mode-tool,
在启动laptop-mode-tool的时候，出现
sudo laptop_mode start
gloger@gloger-ThinkPad-X61:~$ Laptop mode
enabled, active
Activating Runtime PM for device type PCI
Activating Runtime PM for device type SPI
Activating Runtime PM for device type i2c
Error for wireless request "Set Power Management" (8B2C) :
SET failed on device wlan0 ; Operation not supported.
所以安装了linux-backpacks-modules-oneric-generic-pae..然后。。
gloger@gloger-ThinkPad-X61:~$ sudo laptop_mode start
[sudo] password for gloger:
gloger@gloger-ThinkPad-X61:~$ Laptop mode
enabled,
active [unchanged]。。。。。。
请问怎么解决 现在 cat laptop_mode 还是返回0
