Good article. Just a couple of points I'd want to add

If you are seeing weird issues the first place to suspect would be software. My MacBook experienced a series of weird freezes on waking up or going to sleep. When I checked Console I saw this:

11-10-13 5:30:55 AM Skype[228] SkypeApplication::init called
11-10-13 5:31:15 AM Skype[228] ERROR: MacChatMessage wrapper could not FindObjectByDbID by object DBID
11-10-13 5:31:15 AM Skype[228] ERROR: MacChatMessage wrapper could not FindObjectByDbID by object DBID
11-10-13 5:31:15 AM Skype[228] ERROR: MacChatMessage wrapper could not FindObjectByDbID by object DBID
11-10-13 5:31:15 AM Skype[228] WebFlashData cannot find Macrodmedia flash player SharedObjects directory

Which tells me that my old Skype 2.8 was likely the cause. Check Console for error messages first. Only then suspect hardware.

Secondly external peripheral are often an issue. The article is exactly right. Unplug everything and see if the problem goes away. A lot of times a flaky external drive or bad USB cord can make the whole system sick, and these kind of problems can look like something else inside the case.

The other point I'd like to add would be to recommend CoconutBattery. It's a bit of freeware that gives you a much better idea of the health of your battery. Rather than just "Normal" it tells you current charge state, the original design capacity and current capacity of the battery. So according to CoconutBattery my MacBook battery has a designed capacity of 4100mAh but currently it only can hold 3675mAh or 91%. That's actually not too bad considering it's a three year old battery that I have to admit I didn't treat as well as I should have. HINT: they like to be cycled. Don't leave them on the charger all the time.
