My iPhone 5 hasn't been charging or connecting to iTunes when connected to my computer?

I know it isn't the USB cable because it charges and connects to iTunes when connected to another laptop. My laptop will let other iPhones charge and connect to iTunes, and my iPhone will charge until it comes back on when it is dead. I need to know what I can do to allow my phone to connect to my computer.

Try removing the current drivers for your iPhone and then reinstalling them, if this does not work you may have to reset your iPhone.

  • Why hasn't my iPhone 5 been marked as Shipped? I pre-ordered with At&t the first day & it said it would arrive the 21st. I have received one email saying my items are being proceed to be shipped, this was 3 days ago. I keep checking the site to see if they updated with a tracking number.what's going on? I haven't received an email saying it's been delayed or anything. I'm very anxious.
  • Wi-Fi on my iPhone hasn't been working? I have the iPhone 4S and my Wi-Fi hasn't been working since last night. My phone says it connects to the Wi-Fi and as two or three bars. However, nothing will load. Safari, Pandora, Facebook, Instagram, etc. I don't think the problem has to do with the router since my laptop connects perfectly. Does anyone have a solution to help fix this?
  • Is it safe to buy an iPhone that hasn't been fully paid yet? So some guy I met wants to sell me an iPhone 5 for $200. The problem is that he hasn't finished paying the phone. He still has to pay $300 to T-Mobile and I was wondering, if I were to buy the phone, would T-Mobile make me finish paying it off? He said he's going to finish paying it off but if he doesn't & I end up buying the phone, will they tell me anything since he didn't finish paying it & it is now mine? Will I have to finish paying it off if he doesn't?
  • IPhone problems? Hasn't been dropped? I got it just this last September and its worked perfectly until now. When its not plugged in, it won't turn on. When it is plugged in, the Wi-Fi button to turn on Wi-Fi won't work, and it says I have no service. The place at the top where it says your bars(phone service) and 3G or bars or Wi-Fi, that just says: "Searching… ". The date and time are completly wrong too. It says its Wednesday, December 31st. Nothing was wrong with it until this morning.
