I have an application that uses memory card and I need to do some save/restore state operations when the power of the card reader is turned off and on back again. This usually happens after some time of activity and phone goes to a power save mode. In Windows Mobile I solved the same problem by receiving power notifications from the system and take the appropriate action. I would like to know if there is an equivalent of this messages in Symbian?
To clarify, I am not interested in current status of ac cable connected, battery level. I just want to receive notifications before phone goes to sleep mode and after it wakes up.
Thanks.
