Ive searched thousand of google topics And tried 100s of things and no one seems to be able to figure this out. I plugged my iPhone into my laptop and nothing happened,like nothings even plugged in. It doesn't make a noise,charge,or bring up iTunes. I've checked everything with my wife's phone and hers works fine on the same laptop with same cord. My phone charges perfectly using wall outlet or car charger. I've tried connecting to a different laptop and a pc and still nothing shows. I can't restore it cause iTunes doesn't show it. I saw a lot of post from people saying to go into device manager and look for portable device or iPhone and uninstall driver and then reinstall which was like the most common answer,but mine doesn't even show up in device manager cause its like nothings plugged in to the USB. 1 more thing if I power off phone and then plug it into the laptop it will come on but after that nothing shows.
