Hi, I am wondering if anybody else is having this problem. My 770 constantly becomes dead. I just have to leave it aside for a few hours. When I come back it refuses to respond. I even tried to leave it plugged in for several hours thinking the battery had died. The only way to reboot it was to take out the battery for a few seconds. The next time it died I had it still plugged in to the electrical outlet! Again I had to remove the battery for a few seconds. I suppose it could be an application. The only one I run on a regular basis is the GPE Calendar app. I know this app is quite flaky. It always crashes the first time I start it up (after the machine has slept)! But the calendar is my main use of the 770. Any info will be appreciated. Thanks, --shiv--
