Hi everyone! I'm a student and have a Core Duo White MacBook which will be three years old in September. I have been having a couple of problems with my Mac lately and since the Applecare is about to 'expire' thought that I should try and get some of the problems fixed. 1) The bluetooth connection regularly drops with my mouse and my Mac reports "Bluetooth: Not available" The bluetooth icon disappears from System Preferences. A restart used to cure this, but recently it hasn't. Bluetooth can reappear a hour or even a day later! 2) The backlight also has a tendency to flicker and change its brightness by itself. This is probably the main issue I have. It's really annoying to be editing photos and having the backlight change brightness by itself. 3) The final issue is the '/' key doesn't always register key presses. I'd say that roughly 1/2 of my keystrokes to that key are not registered. I have made some upgrades to my MacBook since buying it three years ago. I upped the RAM from 512MB to 2GB and the HDD from 80GB to 250GB. As I'm a student and realise that there is a chance my laptop could be stolen I have a password popping up at start up, login and when waking from sleep. I have also enabled Firmware Password using the original restore DVD so you cannot simply replace the HDD and boot up easily. I also have the invisible shield on the lid, mouse bottom and hand rests. If you've managed to read this far thank you! Should I ring up Applecare or book an appointment at an Apple store (~roughly 30mins drive away and can only get there at weekends)? Also do you think I should replace the original components (RAM, HDD), remove the passwords and the invisible shield sheets? I am a bit concerned about leaving my laptop as although I have a complete backup, it does contain family pictures, documents, letters, iCal calendar etc. I ideally would do a fresh install, but I don't realistically have the time. Thanks for taking the time to read this, any I really appreciate any advice you have. Thanks!
