I run my app on devise iPhone (iOS 4.3.3) And app generate warning "Deregistering for sleep notifications when we have not registered" What is this mean?

This is because I wrote this

[UIApplication sharedApplication].idleTimerDisabled = YES;
[UIApplication sharedApplication].idleTimerDisabled = NO;

After first line, i receive warning: [Warning] IORegisterForSystemPower failed. And Then i try turn off, but it already turn off

Are you using any other libraries that might have registered without telling you? – deanWombourne Jan 12 '12 at 10:44
No,I do not use the libraries – Oksana Jan 12 '12 at 11:45
Does it matter if your app generates a warning? Looks like this property is unreliable (http://stackoverflow.com/questions/1058717/idletimerdisabled-not-working-since-iphone-3-0) – deanWombourne Jan 12 '12 at 11:49
I just wanted to understand the warning,to find the cause. Thanks for help. – Oksana Jan 12 '12 at 11:59
