Hi Andyph81,
Thanks for using Apple Support Communities. Based on what you stated, it sounds like you could use some help with the Sleep/Wake button. I would recommend that you read this article, it may be able to help the issue.
Get help with buttons and switches on your iPhone, iPad, or iPod touch - Apple Support
If the Sleep/Wake button isn't working and your iOS device is on, follow these steps:
- Press and hold the Sleep/Wake button.
- If you see "slide to power off," turn off your device and then turn it on again.
- If you can't turn off your device, try to reset it.
- If the Sleep/Wake button still doesn't respond, follow these steps and test again:
- Check for debris or dirt around the Sleep/Wake button and clean it with a soft cloth.
- Remove any case or film.
If you can't turn on your iOS device, connect it to an A/C adapter. When your device is charged, try the steps above again. If the battery is extremely low on power, your device might display a black screen for up to 10 minutes (up to 20 minutes for iPad) before you see a charging indicator on the screen.
If you have an iPhone 5 and the Sleep/Wake button still isn't working, or works intermittently, you might be eligible for this replacement program.
If you've followed the steps above and the Sleep/Wake button still doesn't respond, if it works intermittently, or if it's damaged, contact Apple Support to set up service.
Cheers
