After trying to install an X11 package, I\'ve found that the Zaurus will no longer turn on with the On/Off button without switching the battery switch to \"Replace Battery\" position first. After doing this, the On/Off button works and turns on the Zaurus, and everything seems to running ok. But when I turn it off, I again have to change the battery switch position before I can turn it on again. Any ideas on what\'s wrong?
