If you forget the password, the only way to get back in is to perform a "hard reset." Performing a hard reset causes you to loose all data on your phone unfortunately (numbers, texts, and all). Hopefully you've sync-ed up your data on your computer recently.
To perform a hard reset, do the following:
1 - Remove the battery cover.
2 - Take out the battery.
3 - Put the battery back in. An orange Palm logo will appear on your screen.
4 - While the logo is showing, press & hold the Power/End button until a black status bar appears on the screen, fills completely, and then goes away. Then you can stop pressing the button.
5 - Next on your screen will be a prompt to erase all data. Press up to say Yes.
6 - Next select your language and you have an empty phone to start a new. If you've previously sync-ed up your data, you can sync up now and add it all back.

SOURCE: My palm centro began hot
The problem is from the connectors on the bottom getting wet, slightly
moist, oily from your hands touching it or just plain dirty. This sends
an incorrect signal to the phone that makes it think the cable is
attached and requesting what ever action is initiated by pressing the
button on the cable, which is set by default to initiate hot-sync.
Two things can make this problem bearable or even resolve it:
Clean the bottom connectors to resolve the incorrect request for action being sent and/or reprogram that cable button action to do something different, like go to the phone's home screen instead of initiating hot-sync.
I take a packaged alcohol pad like they use at the doctors office (not a cotton ball, the fibers get stuck in the grooves and deposit too much alcohol in the phone) and wipe the bottom connectors down really, really well. then let dry. two or three times of doing this _always_ fixes the problem for me. I let a lot of alcohol get in there but the pads don't contain all that much extra which is why you should use the pads to keep from damaging you phone! (they are cheap at wal-mart.)
In the meantime, reprogram what the phone does when it receives (or thinks its receiving) a signal from the cable button press. On the centro, go to Preferences --> Buttons --> HotSync, then set the app you want to activate. I use "phone" so when the problem reoccurs, my phone keeps sending itself to the keypad, not the long long process of activating and canceling hot synch.
You will have to manually launch the HotSych application from the home screen when you synch if you keep that button the same or you can just change it back to the default when resolved.
Hope that helps!

This happened to my palm centro and i fixed it myself. :) Maybe it will work for you. What i did was take out the battery and so the phone is completely off.. then take a tooth brush with rubbing alchohol on it and scrubbed the bottom part of it that the hotsync cord goes into.. I thought this may just mess up my phone more but i plugged it back into the power cord, turned it on and it worked just fine!! Seriously, try this out. It brought me so much relief!! And chances are you either got some **** stuck up inside there, or you got the botton part wet. Hope i helped!!
