Hit there I am a happy switcher! I use my macbook 1.83Ghz white with no problems for the last 2 & 1/2 months. But the first problem just appeared.. I connect my macbook with an external display via a minidvi to vga cable , in order to use it with the lid closed. The problem is that SOMETIMES when i disconnect my macbook from the external display the macbook's screen doesn't turn on.And i have to do a restart. Yesterday I connected it to the external display , but the display just showed the blue background with no icons at all. I couldn't again power the macbook's screen so I restarted. The problem is that this happens not every time but once in a while! Does anybody else have similar problems? Thank you!
