How to reset

Try a factory reset. Sounds like software malfunction. But as above said, could just he battery. You will loose all info with a reset

The battery may be damaged. Better to take it to a dealer and get a new battery.

take battery out,let sit for 30 minutes,put battery back in and enter proper password,if you cant then you will need to reset to factory settings

There are a couple things you can try. First of all, back-up your phone, then do a factory reset from the settings.

The second thing you can do is to fold a piece of paper a few times and put it against the battery, then close the back. Use something to basically hold the battery tighter in the phone, and see if this stops the restarting. It's possible that the phone is restarting because the battery isn't securely in there, so some pressure on the battery, when the phone is closed again, might help to keep it wedged in there tightly.

If neither of these things help you, it is possible that the phone has a hardware fault, and is restarting because something is wrong with the actual circuit board or something inside of the phone.

You could either send it in to get fixed, or you could replace the phone with a new one.

However, it's always best to start with the free options first.

So, use something to hold the battery tightly in the phone, and/or factory reset the phone to ensure it isn't a program that is causing the phone to crash and restart.

Best of luck!

Could be lock by,try to reset.

it is not in cmos battery .........You need to put of the battery and the start the computer it will then reset.Then put back and the fan will work

Fail safe in the battery has engaged. See if the computer will start without the battery, using just the power supply. If you can get it started then put the battery in and see if it will charge or reset the fail safe. Give it about an hour, then shut it completely down and restart it with the battery in. If it won't start at this point, then you will need a new battery. Also change the CMOS battery inside the computer






Change the CMOS battery

I just purchased an older Furby in a box too. It also wouldn't start up, even after I reset it several times and put in different batteries. Finally I just set it aside, with the batteries still installed, and it started up by itself about 30 minutes later. After it went to sleep I pushed on it's head to restart it, but it needed to be picked up and restarted by pushing the bottom a couple of times. I "fed" it until it "burped", and it seems pretty energetic now. :-)  Hope this works for you.

Try taking out the batteries and reinstalling them, if this does not work there should be a reset button (pin hole). This should do it. Please let us know if this solves your problem.

I heard this happens after updating the Treo 650 with the new version 1.17. Is this your case? If so just remove the new update... Anyway, you can try the soft restart or even Performing a system reset(from the user guide p.170): ".. Performing a soft reset A soft reset is similar to restarting a computer. If your Treo is not responding or you have trouble synchronizing with your computer, a soft reset may help. 1. Press the Battery Door Release button and slide the battery door downward to remove it from your Treo. 2. Use the stylus tip to gently press the reset button on the back of your Treo. .."
