Hello, im new here anyway i have a problem and i read an existing post on macosx
http://macosx.com/forums/mac-os-x-s...puter-shuts-down-after-minute-inactivity.html

and that is exactly my problem. after 70 seconds of inactivity the system throws a message on my screen to
Logout, Cancel, Restart, Shutdown

If i leave it as is it it shuts down the system in 10 second.

someone suggested in the old post that its a keyboard issues and the issue was solved after a key board replace.

now my system did fell recently from the bed but im not sure if this is really causing the issue.

changing keyboard will cost me a lot.

Can someone pls advise

If you did not have the issue before your Mac fell, then the fall is probably related. That sound reasonable to me, anyway :D

There's some helpful tips on the thread you linked.
If you checked into all of those possible tips, and nothing helped, then, yes, it's very possible that the keyboard is at fault.

If your problem is repeatable - leave it for a minute or two, and it always shuts off - then a service shop should be able to sort it out pretty quickly, and you can decide if you want to spend the money to get it fixed

Can you tell us exactly which model of laptop that you have, and how old it is?

Hello,

its fine i ran into an issue, what confuses me is that the system fell and it worked fine for 2 weeks and then suddenly this issue came
to surface. now why does it only triggers the shut down when its inactive, why it does not do that while im working on it?

the fall should create an hardware issue but this seems to me more of software issue
my mac details

Model Name: MacBook
Model Identifier: MacBook5,2

I dont know when exactly i bought it, may be end of 2009 or 2010
 
I missed:

I tried doing the PRAM or nvram reset, in which i turned off the system remove the battery held power key for 5 seconds and
released it. but it did not solve anything.

let me know if you need more details of my system
 
Test that you don't have a corrupted settings file for the Power Manager:
Go to the main Library folder on your hard drive, then to the Preferences folder, then to the SystemConfiguration folder.
Drag the file com.apple.PowerManagement.plist to the trash.
Restart your MacBook, and your MacBook system will create a new file, with default settings.

You could also check if there is an issue with your user files, by logging in to a different user account (create a new user just for this purpose). You should be able to tell if the issue is just your user by letting the system idle for a few minutes while logged in to that new user. If you again get a shutdown, then it's system-wide, or a hardware problem of some kind.
Be sure to try a PRAM reset (which is different from the System Management Controller (SMC) reset that you did in your post #4)
PRAM reset: restart while holding Command-Option-P and R keys.
You should hear the boot chime sound. Continue to hold those same four keys for two more chimes, then release the keys to let your Macbook startup normally. There may be a delay of 5 to 10 seconds between each reset. You may also hear the optical drive audibly whir during each reset cycle, although some MacBook models don't make much noise from the optical drive.
I doubt that a PRAM reset will fix your issue, but it won't hurt anything to try that reset, if it's something that you haven't tried yet.

I tried all but nothing worked, i think i will take it to mac technician. im not sure what specific hardware part is causing this?

i dont know i thougth may be i will reload the OS before checking with local technician

do you think i should try reloading OS?
 
Yes! That's the whole point - you DON'T know what specific part is causing this, and that's why you would take it to a service shop.
Maybe a reinstall, or an erase and install will fix. It all takes some time, eh?

So, reinstall OS X, as it COULD be software. You may find that there's no difference, so you could THEN try a complete wipe and install. You would lose EVERYTHING that you don't already have backed up, so make sure about that before you begin.

My suggestion would be to boot to an external hard drive, where you have installed a basic system (without all the extra "stuff" that you may have installed... )
If your laptop continues to shut down, even when booted to a different volume, then that's your best clue that you have a hardware problem.

I have two partition for the HDD, should i install OSX into other partition and boot it using the same partition and check?
Would this be equivalent to booting from an external drive (or a fresh boot up)?
 
Yes, that option to install OS X on a second partition would be fine, assuming there's enough space. 20 GB would be enough.
