I was using the device

there are many things you can do to fix a pda. the least time consuming of course would be to turn it off, remove the battery, wait a minute and then put it back together and turn it on. you have to remember that a pda is more a mobile laptop then a phone. a restart should always be your first action. second would be a hard reset. this wil restore your pda to factory settings. on the upside it will be like brand new. on the downside you will lose everything not saved to your memory card or backed up on your computer. a word to the wise, make sure your phonebook is backed up! nothing is worse than losing all of your saved phone numbers!

try change the battery and c GOOD LUCK
