Check and make sure the charge hasn't gone to full 0, could be a bad battery pack, or charger circuit. If they are OK hold it under water in the back of the toilet for 3 minutes or take it to a TECH because you sure aren't going to be qualified to fix it or you wouldn't have come here.

No, it doesn't look like it.

You will need to download and install Microsoft ActiveSync (for windows XP) from:
http://www.microsoft.com/windowsmobile/en-us/help/synchronize/activesync-download.mspx

In case using Windows Vista or WIndows 7, download and install WIndows Mobile Device Center from:
http://www.microsoft.com/windowsmobile/en-us/downloads/microsoft/device-center-download.mspx


After installing the appropriate program, connect your phone to the laptop and you would see your phone in My Computer and can copy the data from it and into it.

Goto the main website and they have it to where you can trouble shoot from there website. And also download files you don't have that you need for whatever program you have.

I got nothing but a Access Solutions W770 Wireless system. Is that what you are looking for?
