Question

My macbook has been a good and trusted friend for nearly two years. Once in a while the screen would flicker a little when it was first woken up, especially if it had been asleep for some hours.
However its every time I wake it from sleep now and the flickering can be quite dramatic. After a while it settles down.
Would this be the back lighting on its way out?
Other problems include sometimes not hooking onto my network from sleep, shutting the lid and trying again usually works. And sometimes when I close the lid, it won't goto sleep and keeps going until eventually killing the battery. Or sometimes trying to restart it will restart making then DVD drive noise, then it will do it again before restarting.
I have a few months of warranty left, would these symptoms, especially the screen be classed as wear and tear?
Can I expect them to fix it even though I changed my own harddrive?

Answer 1

If it continues to reproduce itself under the original hard drive, your case for having it repaired under warranty would be stronger. As long as when you reinstall the drive you don't damage your system near the drive any further. A repair technician would be able to tell the difference if the replacement of the drive affected the system's stability or not. Still, you should consult with a technician what your options are.
