My Garmin 305 won't turn on or power up

My heart just about stopped today when I went to use my Garmin 305 and it was completely dead. I depend a lot on my heart rate monitors while I train. I tried a couple of different chargers and it wouldn't come to life. I left it on the charger for awhile hoping it just needed to charge. It still wasn't working an hour later. Luckily I found this tip on the gamin website:

You have to hold down the "reset" and "mode" buttons simultaneously then push the on/off button while holding them. It powered right up and all is right in the world again!
