The screen of my android phone sometimes automatically shutdown and cannot reshow again. So how can I shutdown my android from PC or other ways?

You can do this with adb (Android Debug Bridge).

  1. Enable "USB Debugging" on the phone (Settings > Applications > Development > USB Debugging)
  2. Type adb reboot in a terminal in the directory where you installed adb platform-tools

Will it slow down the phone? if I enable the usb debugging in my phone. – lovespring Jan 23 '11 at 9:50

@lovespring: USB debugging is only active when you plug the USB into a computer and adbd is active (i.e. you started adb in the computer), and in my Samsung Spica, there is no noticeable difference in my Linpack score when USB Debugging is "disabled" and "enabled while running Logcat" and "enabled but not running Logcat". YMMV. – Lie Ryan Jan 23 '11 at 10:26

  1. Hold the power button down until it shuts off.
  2. Pull the battery out.

If I pull the battery out, the sdcard file system crashs, all file lost! This is why I ask this question. – lovespring Jan 23 '11 at 11:41
That's not at all clear from your question. – Matt Jan 23 '11 at 20:08
@lovespring Notice the order of the steps here. They are very important, and if you follow them completely, you should be safe. – Kevin M Jan 25 '11 at 0:29
@Kevin The power button just shows a menu. from the menu I can select an item that shuts down the phone. – lovespring Jan 25 '11 at 8:41
If you hold the button longer, it will initiate a shutdown. – Al Everett Jan 25 '11 at 19:01
