Hi,
I have a 2011 Macbook air. I will list the problems that I am experiencing, though I do not know if any of them are related in any way.
First, the specs:
13-inch MacBook Air, Mid 2011
1.8 GHz Intel Core i7
4 GB 1333 MHz DDR3
Intel HD Graphics 3000 384 MB
OS: Mac OS X Lion 10.7.5
251 GB flash storage, of which 181.81 GB is free
Issues:
1) Extremely sluggish: When booting normally, there is significant (1-2 second) lag when moving the mouse and clicking on anything (using either trackpad or external mouse. This lag, however, is solved when booting into safe mode by holding shift while booting. However, safe mode is not a complete solution (as sound is disabled, videos won't play etc.)
2) When booting normally, activity monitor marks a process called "kernel_task" to be using 300-400% of my CPU. In safe mode, the task is still present, but with a CPU usage of between 5-10%.
3) The battery no longer charges (and no longer works?). Computer must be plugged in at all times for it to work. Unplugging the magsafe causes the computer to immediately turn off. Curiously, under the battery menu, it says "No Batteries Available," but also "Power Source: Battery."
