I am a college student. I brought my MBP in to the store in my home town over winter break complaining of a dying back light (it flickered on and off, then died for a period only to come back again and die intermittently.) and of a lagging mouse which would correct itself upon a reboot. They replaced the screen and said they could not diagnose the mouse issue. Since then,the screen thing has been acting up more, it often times will not wake out of sleep mode, and the DVD burner will not burn DL dvds. I brought it into the store over spring break (this week), and of course, all the problems went away as soon as i walked through the door. They took it in to observe and try to get the problems to happen, but no luck. I told them to keep it for another day. These are really unbearable issues, and I hope apple can fix them. If not, any suggestions?
