Screen Goes Black after a few minutes

me too

and what happens if you use one?

Nothing changes. I've tried using one that came included with Leopard, and the backlight turns off before the screensaver kicks in.

It's clearly NOT a screensaver issue. I have this problem, doesn't matter whether I use a screensaver or not, doesn't matter what my energy settings are, doesn't matter if I stand on my head while setting this to NEVER shut off, it still dims every few minutes and I have to keep touching the mouse pad or the keys to brighten it back up so I can continue watching or reading whatever I am doing. I have tried every piece of Voodoo listed in this topic, none of it makes any difference. It doesn't stop me from using the MacBook Pro, which is a really nice laptop otherwise, but it is **** annoying. I love it when I'm trying to show something to a colleague and I have to keep touching the thing to make sure it doesn't dim down....

that stinks that yours still dims on never. when i put it on never, it doesn't go black or dim, unless i have dim checked.

Strange, maybe it is only indirectly connected to the screensaver. I mean, it was REALLY bad on mine until I've changed the screen saver.

Anyway, have you tried deleting the following plist's?

com.apple.PowerMangement.plist
preferences.plist
com.apple.airport.preferences.plist


which you can be found under:

Mac HD - Library - Preferences- System Configuration

Then restart.

I find that zapping PRAM and clearing SMC sometimes works better when I also delete these files manually.

I am glad to see I am not the only one who (1) can't figure out why my screen goes dark after a few minutes (annoying if you are watching a film) (2) The first key entered doesn't appear on screen.
At first I thought I was going mental, but alas, it's a bug. It can't be I forget to type the freakin' first letter all the time!

I spent over $3,000 on this MBP and it's just over a month old. I am rather ****** off!!

its not a bug. In system preferences, go to display, unclick Automatically adjust brightness as ambient light changes.

Clearly you haven't been following this thread. That is not at all what we're talking about.

read the thread before assuming you know what you're talking about

try going to your hard drive and then the following folders: library, preferences, systemconfiguration. get rid of the file com.apple.powermanagement.plist and reboot. had same problem of screen going black after 20 seconds regardless of any screensaver, energy saver or keyboard settings. not having the problem anymore.

mmt2111,

*A little care and rigour please*.

This does not solve the bug.
You do not read all the messages, It was already tried.

*Please, read the complete thread.*

no need to get testy. i had read some related posts on this issue and didn't see this. i was sitting on the phone with a so called apple product specialist and referred them to this specific listing to see if they had any other options than they described here. didn't read this thread too closely bc the apple technician put me on hold for ten minutes saying that is what she was doing. i did what she suggested and it seemed to work at first. my screen was going black after 20 seconds. after deleting that file and rebooting a second time it is going black again, but now it takes a few minutes rather than the 20 second period before.

*Once again*
*This does not solve the bug we are talking about*
*Only select the screen to dim before going to sleep resolve the problem.*
*But it is not satisfactory and broadly inadequate.*
Read the complete thread please.

i think 10.5.2 has fixed this. so far, so good for me.
