Hi. I am on the road without a UBS connection for my 7250. I was charging it with an AC adapter when out of the blue it beeped a few times and shut down. It won't reset (taking the battery out and reinserting). The red light blinks 4 times in sucession every 2 to 3 seconds, that is it. Any suggestions?
thanks in advance.

Try reinstalling all the software. Something similar happened to me and that's how got mine back.

Are you sure that the AC charger was working. Sounds like (maybe) a dead battery....

thanks for the notes. The battery was charged, although I suspect there may be a battery fault. However, the red lights were flashing for a day (and then died). I get back tonight and will see what happens when I hook it up to the pc. Thanks.
