Rispondi a: Camera not working in camera app, but working in facetime and snapchatWhilst it may not help this case, but just as an FYI. The iPhone 5 back camera has a history of having a terrible connection. If the back camera goes (and the front still works), just try giving the external camera glass a firm press... This is normally enough to spring it back to life.
Rispondi a: Laptop Fan not rotating?I have had a few laptop fans die on me before. Often it is due to dust that either blocks connections. The first thing I would try is removing the fan and giving it a good clean, checking connectors etc. You'll be surprised how many of them spring back to life after a simple clean... Let me know how you get on :)
Rispondi a: won't start the machineIochlan Hua, Have a look at the documentation and I would first try a factory reset if possible. As this would conclude there is physical damage. After that, I would take the covers off and have a look inside for any obviously damaged parts. As could just be something as simple as a sensor that has been jolted to a different position. Give this a shot and let me know how you get on :)
