Hi everyone. I'm fairly new to macs, but I'm familiar with macrumors thanks to iphone 4 and 5 rumors. I just got my first mac from a friend of mine and I really love the way macs work. But the reason they gave this mac was because of a weird problem it's having. (it's a 2009 13" by the way) Essentially, the keyboard/trackpad are not recognized at all upon booting sometimes. HOWEVER, if I boot it and they ARE recognized, the computer will work perfectly fine for weeks, until I shut it down completely. At that point, it may or may not recognize on the next boot. For example, last week I was using it, and the battery died. So, I plugged it in at home, restarted it, and no keyboard/trackpad at all. (backlight is still on). So, I plug in a USB mouse, and reboot it 3 more times, nothing. I go grab a snack, come back, boot it, and everything is working great. I put it to sleep that night, woke it up in the morning, etc. for several days. No problems at all. I even did an update and restarted, it booted fine with keyboard/trackpad. Then, just for fun, I shut it down again. It booted 5 times perfectly. The 6th time? No keyboard/trackpad.... I'm fairly familiar with PC's and I'm not afraid to open up the mac if necessary. (it's clearly out of warranty), I'm just looking for any experts opinion on why this is happening, and how I might be able to fix it? I don't have an apple store near me either; so I can't take it in. Thanks for any and all help! p.s. I'm typing on it right now.
