Power notifications and C500

[Guest dh]

I've been developing an app that keeps the backlight on when connected to an external power source.

With the E200 all was fine, I used the RequestPowerNotifications call and got notified when a PBT_TRANSITION occured. When running the application on the C500 I no longer get the PBT_TRANSITION notification and only receive other notifications such as PBT_POWERINFOCHANGE, and PBT_POWERSTATUSCHANGE every ten minutes. The 10 min interval starts from when the phone first starts up, not when the RequestPowerNotifications is first registered or when the application loads.

Any ideas?

I'm developing in c# but haven't had any luck with the .net cf forum.
