TREO 650 phone won't turn on

[bobtreo]

Did a Hotsynch from my Desktop to the handheld after replacing the user data under my user name with a user data where my contacts were reorganized.
The hotsynch worked. I did not try to turn my phone on right after this. The next day, my handheld works, except for the phone which will not turn on.
Did I cause the problem, and if so, how can I correct it?
Thanks in advance. Bob

Replying my own question.
It probably was not cold enough yesterday (-3F) This morning, the temperature reads a frigid -10F. Woke up my Treo. It works now.
Conclusion: put your Treo in the freezer if it gives you any kind of trouble.
Have a good day. Bob
