I've been using a Powertap SL for about eighteen months with good success. However, the last few days I've been encountering a strange problem. My computer works fine while on a ride, but by the time I connect it to the PC cradle it's sleeping and won't wake up. Eventually after fiddling with the buttons and shaking it will come around, but it's completely zeroed out. However, if I sync it, my ride data is still there. It took me until today to realize that - yesterday I pulled the battery out to get it restarted :-(
Some more info: batteries are newish, I'm not seeing any lowbatt indicators. No problems whatsoever while on the bike. I don't think it has anything to do with the cradle since it won't wake up even when it's not docked. I have the "start a new ride after N minutes" set to 120 mins., the longest I've gone between end of ride and downloading is 20 minutes, usually more like 10. Sleep is set to 5 minutes.
