Try hard reset, this has happened to me. Hold the power and home buttons until the logo comes onto the screen. Try this when your phone is plugged in just in case it is dead.

What brand? Check clips and striker prong on door, as you may have a bad safety switch.

Having gone over a month without a response, I assume the hard reset did the trick.

Depends on whats gone wrong and what version of windows you have. Many options but if you want to start from scratch insert the recovery cd and boot from that at start up. Sometimes you can access recovery options at boot time by pressing F8 or r repeatedly during start up.
the rest should guide you through.

If its totally dead and you need to get data of beore reinstalling, then download pppylinux and burn it onto a cd then boot from the cd, this should then run as a totally new operating system that allows access to all your data, you can even save it of onto cds or external usb drives.

They connection from charger to device may be broken to try and call the manufacturers for advice

try cleaning battery contacts on phone and on battery with alcohol, maybe they oxidized

try a hard reset. hold down green and red and power same time push the reset button located by the charging port

You will have to open up the PDA case and take out internal battery (round one). It might just need to be replace or resitted. Next time, backup your data to a memory card.

this thing is obsolete, nobody uses them now,
why not ask HP this, and not fixya, HP made it why ask here.
