After I used it this morning, it would not turn off by pressing the on-off button. I finally had to put the unit back to the cleaning / charger holder, and it stopped operating. After this incident, the unit does not turn on by pressing on-off button. It does not even turn on with the directly connected to the power.

hold the power button down for 10-15 seconds to force a power off. When turning back on, hold the power button down until you either feel it vibrate or something comes up on the screen.

Hi,
Charge the phone for 10 minutes.
Press down the volume up button and hold it and then press the power button for a few seconds . The device will restart.

your starter button is malfunctioning. maybe some oxidation in the switch. when starter button is pressed in that can cause your other electrical stuff to not work.

These units seem to be suffering from a bad connection on the inside of the unit. My wife's did the same thing. There was a connection inside that wasn't making contact. First try cleaning the 4 brass connection tabs on the watch and check your charger to make sure the tabs are raised and not squished. Second try to reset the unit. Hit mode reset and power buttons all at the same time. Hold these for 3 seconds and then release. If these do not work here is what I did. There are no screws holding the unit together. I used a exacto blade to very carefully pry the unit apart along the side seam. It's not easy to do. Be very cautious and gentle. Work the thickness of the blade into the joint to gently wedge apart. You are not trying to remove material! Once apart you will see some fingers that make a connection between the upper and lower part of the unit. This is where the problem was with my wife's 305. I gently raised these tabs to make a better connection, It's been working ever since. I didn't try it before but try pressing very hard on the unit where it says Forerunner 305. The case is very hard so it might not work. But if it powers up when pushing you found your problem. Hope this helps. Here is a link I found on opening a 205 (Same process) http://ctorunner.googlepages.com/dismantleforerunner205 To put the unit back together use Automotive silicon/gasket maker. Use a tooth pick to put a VERY small amount of silicon around the entire seam. Put the two half's together and wrap tightly with electrical tape. Test the unit immediately to see if it powers on and off. If it does not open it back up and raise the small prongs that make the connection from the bottom half to the top half. If any silicon squishes out the sides wipe with water and a rag. Let the unit sit over night. In the morning remove the tape.

Let me kinow if this helps.

I don't know if this will work but I had a similar scare this morning, it could be that the charger isn't quite making contact with the phone, so make sure that the charger is pressed onto the correct part. (the metal part from the charger is pressed onto the metal part in the phone) I had the same thing where my phone was charging all night and it wouldn't turn on. I just had that at&t logo. I pressed the charger right and tried turning it on again and it finally came on. I hope this helps!

Soooo scary when your phone goes out!!

Something similar happened to me. I finally gave up on my wall charger and tried connecting my PDA to my computer and pressed reset button several times. I left it connected overnight and It was working by the next morning. My guess is that my battery was completely drained and my wall charger quit working.
