Computer randomly goes straight to sleep

Question

Okay...so with still having this issue: https://discussions.apple.com/message/16362086#16362086
Ever since I perfomed PRAM (with is holding down those keys until you hear two startup chimes) sometimes when I'm using my macbook pro it randomly (mostly it's after I had fiddled with the adaptor) it goes straight to sleep, then I rewake it, and then the screen goes blank like it's shut down.. I turn on the power button and it still doesn't start up but makes a "pew" sound...when I finally press the power button a few more times it finally starts back up. Does anyone know what could be this problem and any steps I could do to fix it? I feel like I'm trying to do everything to fix my computer but trying to solve it makes more errors... sigh.
And, with the charging issue that I posted above...could a brief power outage do harm to my computer? I have noticed the problems happening after the brief outage we had a few weeks ago. I don't know how it would have done that much harm though.

There's always someone cheaper . . . but Macs are . . . unique. I wouldn't trust mine to just anybody (actually, I won't trust mine to anyone at all, I try to do the work myself, unless it's under warranty).
I also wonder if it could just be a loose connection in the laptop...that's what I'm hoping anyway, just something that could be easily fixed.
Definitely could be.
I am also hoping it has nothing to do with how the laptop is controlling the temperature. How do you check logs on the Macbook for errors?
Applications > Utilities > Console
Also, just because the Genius says it's the logic board...does it always mean their right about it?
I always put "genius" in quotations marks. They're only human.
To do disk utility is there more info about how to do it some where?
First check the S.M.A.R.T. status on your HD: Applications > Utilities > Disk Utility > in the panel at left, select the first item in the list/your HD mechanism > look at the bottom of the main window next to S.M.A.R.T. status and see if it says “Verified” or something more ominous like “Failing.”
If S.M.A.R.T. status is "Verified," run Verify Disk > click Verify Disk at bottom of main window. If a message comes up saying you need to repair your disk:
Boot from install disc (insert disc > restart > immediately hold down the c key and keep holding it until you see “Preparing Installation”) > at first screen select the language and click Continue > click on the Utilities Menu in the menu bar > select Disk Utility > select your HD in the panel on the left side (the name of the HD’s manufacturer and the model number, usually the top item in the list) > click Repair Disk at bottom of main window. Run this at least twice, and keep running it until it says “appears ok” twice in a row. If that doesn’t happen, you may need a stronger utility (such as DriveGenius, TechToolPro, DiskWarrior) or if the directory is damaged beyond repair, you may need to reinstall the OS, or you may have a damaged HD which will need to be replaced (repair utilities can only repair the directory structure, not the HD itself). When this is finished, quit Disk Utility, quit the installer, and restart. Once booted normally, go to Applications > Utilities > Disk Utility and run Repair Permissions.
I'm kind of unfamiliar about it and worried I'll mess it up. Is it easy to mess it up? lol
Pretty tough to mess up, so not to worry.
