Instant shutdown by pressing the power button (Ubuntu)

http://askubuntu.com/questions/86376/how-to-specify-power-button-to-do-a-shutdown-h-now-instead-of-graphical-shutd

That's simple enough. When you press the power button a ACPI event triggers the script at /etc/acpi/powerbtn.sh.

You can edit that to just run shutdown -h now as the first thing so it looks like:

#!/bin/sh

# /etc/acpi/powerbtn.sh

# Initiates a shutdown when the power putton has been

# pressed.

/sbin/shutdown -h now "Power button pressed"

exit 0

# leave the old code below (in case you want to revert!)

電腦保養心得

1) 防毒軟件
相信沒有人不安裝防毒軟件, 不過很多人都忽略防毒軟件的更新. 電腦病毒日新月異, 防毒軟件之所以能偵測是因為防毒軟件廠商會每日都會準備病毒樣本更新給自家防毒軟件下載使用. 沒有更新的防毒軟件比沒有安裝防毒軟件更危險, 因為那會給使用者虛假的安全感.
就一般而言, 防毒軟件是會自動上網更新; 但以有例外: i) 電腦沒有連上互聯網; ii) 防毒軟件過期而使用者不留意: 這個情況最常出現於隨廠機附送的防毒軟件試用版.
個人使用Microsoft Security Essentials (MSE): i)小公司商用免費; ii) 即裝即用, 不用每年再行註冊

2) 定期資料備份
個人使用MozyHome Free, 2GB免費, 會定期自動把文件作備份.
有預算又不想為此煩惱的人可以考慮Backblaze,每個月不用US$5就可以線上備份整台電腦的資料.

3) 定期電腦硬件檢查
電腦中最常出現問題的部分是硬碟(Harddisk)和記憶體(RAM)
