Require password w/out turning off screen?

Hello,
I'm wondering if there is a solution to my issue. I am hoping to run a slide show on my laptop and would like to lock out users from turning it off/making changes. Is there a way to do a screen lock w/out shutting the screen off? I know I can require password when returning from suspend. But i do not wish to put the device into a suspend mode, but rather a "sleep with open eyes" type of thing.
Thanks,
M

Back up all data.
In the Finder, select Go ▹ Go to Folder... from the menu bar, copy the text on the line below into the box that opens, and press return:
~/Library/Preferences/ByHost
From the folder that opens, move the following file to the Desktop:
com.apple.screensaver.*.plist
Here * stands for a long string of letters, numbers, and dashes.
Log out and log back in. Reset your Screen Saver preferences, including the timeout. If you're able to do that, delete the file you moved to the Desktop. Otherwise, you can put it back where it was.

The only way you can turn it off is to close the lid - so you would need an external wired or wireless keyboard and mouse/trackpad attached.

Turn-Off screen keeps coming up - maybe broken sleep button?

hey there,
i got my 3gs on saturday (t-mobile, germany) and it worked great for exactly one day. on sunday i noticed that the phone woke up from time to time showing the turn off screen, which usually appears if you hold down the sleep button for some seconds (red slider at the top).
after that, the same screen popped up more often, it even interrupts other actions by appearing on top of applications like phone or mail.
sometimes the phone will make a screenshot of the current screen if i push the home button, so it seems like the sleep key is stuck.
the phone has no visible damages, the button looks normal and doesn't act jammed.
all this happens unpredictably so i can't reproduce it, but its happens pretty often by now and is anoying as ****
i tried restarting the phone, resetting the prefs, resetting everything, restoring in via itunes etc.
guess is have to send it back, i just wanted to ask for more ideas and leave a mark for other affected users.
regards
jan

Bad news. I got my 3GS Saturday (6/27) at the local Apple Store. By Sunday morning, I noticed the "random" power off slider. Sometimes, the sleep switch works, sometimes it doesn't. It's gotten progressively worse...after less than 72 hours of ownership. I have a case open with Apple and a Genius appointment in 2 days. In the meantime, I suggest you DO NOT power off your phone. Apple had me do a reset (for the 4th time) and the phone would power down DURING the boot. After 10 minutes..and pressing NOTHING, it suddenly started up and ran. The sleep switch is virtually dead. The Apple rep mentioned something about "cracked circuit boards", but did not elaborate. I suspect something in the assembly process is trashing the board the switch is attached to.

I would like to know if I can turn off screen rotation espicially in music.
Thanks,

Unfortunately, you cannot with a 2G iPod touch, and, if your info is correct at the bottom of your post, not with iOS 3. This was a feature for iOS 4, but again, even if you had iOS 4, 2G's weren't given that feature for whatever reason.

Turn off screen while using Drive

Hi,
How can I turn off screen, to save battery, while using Drive? When I press power button, screen turns off, but I lose voice navigation.

Hi karlo1020lumia,
Welcome to the forum!
What is the model of your device? If you're referring to the Nokia Drive application, this is a normal behavior. The screen must be active for the application to work properly. If your concern is about the phone's battery, you can check this link for the tips on how to prolong the battery life of the device:

Hope this helps. Let us know the outcome.

The iOs 5.1 is a huge file that needs to be dowloaded when updating/restoring, your phone hasnt completed the update so its now in recovery mode. Look on the left of itunes, it should say downloads under the store section with a spinning wheel, click that and youll see the update file with a time remaining, wait for that download to finish then try the restore again and it should work

Random laptop screen Black out / Turn off .

Hi,
first of all my laptop is : HP Pavilion dv6-6160se Entertainment Notebook
to the problem now
A few days ago my laptops screen started out of a sudden shutting down/turning black( no lights at all ). This was happening while using the laptop at random. The screen had no lights, and if i use a flashlight on it there is nothing. like its turned off completelly.
Before this happens. Ths behavior varies. Sometimes it flickers from my desktop to a black screen then back on and some times not. Most of the times screen changed to a radom color (green mostly) then becomes black/shuts down.
NOTE: The laptop keeps runing, i can hear the videos playing so it probably isnt a gpu chip or gpu issue , music and games.
I searched the web for all kind of reasons that this could happen and tried some of the fixes .
Here are everything i tried and all or the details i could accumulate in past coupe of days:
1. If the screen flickers , blacks out and then turns back on i get a message that gpu drivers have stopped working and recovered ( on both amd and intel ).
2. If the screen blacks out, on rare ocasions if you close the laptop lid and let the laptop go to sleep , when waking up screen works again ( noticable due to screen moving)
3. I tried installing 4 different drivers all with clear install. ( didn't work)
4. I tried to to recover system with restore point. ( didn't work)
5. I tried to lower the screen brightness. ( didn't work)
6. tried this trick:
Turn off laptop
Remove battery
Hold the power buttong for 30-45 seconds
Plug-in the charger ( dont put the battery in )
Turn on laptop and see if it works.
Very Noticable details:
7. Since on of the rare fixes requires to move the lid i tried shaking the screen a bit or pushing it slightly to different directions. This actually does the trick and turns the screen back on ( i am right now typing this after using this "trick"
So, with this one as a hint there are a couple of stuff i have in mind but i am not sure and need help since i am not a technician.
a) There is a loose LCD cable and when i type a little vibration moves it and ends up in a black screen.
b) I read that if you use a flashlight and you cant see your desktop it means its a bad inverter.
c) Can the inverter have a lose cabe instead of the lcd ?
That's all the feedback i could give you that i can recall now.
Currecntly the screen looks ok ( maybe its the certain angle it has after i moved it so i would aprecciate a fast reply before it goes black again
EDIT: Tried to play a game for a few mins and i got the black screen again. Closed the lid so the laptop goes in sleep mode then opened it and it worked. Just for the records.
EDIT#2: Just tried to play a game again. got the blackscreen, shaked the screen a bit and it worked but for the 1st time i get the message " Application has been blocked from accessing graphics hardware" , Can it be that its the GPU after all or maybe drivers?
EDIT#3: Tried to play a game again and it seem to trigger the issue . ( i am currently running the laptop with only the intel drivers installed)
thanks in advance
Sincerely,
Ntas
P.S. Please feel free to ask me any question if you need more information, i am not a laptop expert but i know more than the average person

Hi @Ntas
I have read through your post and it seems there are a couple of possibilities, and I noted that you have already tried several of the things I would normally suggest.
I will however post some of those links anyway for you to review, it is always possible there may be something in one of them that may have been missed or may inspire an idea of the cause. Since you mentioned that sometimes just moving the screen will cause the problem or make it disappear, that does seem like either a loose connection or maybe something like pressure on a part of the display causing the issue. Of course that last part may just mean the display is on its last legs, but hopefully not.
First I will give you a link to the service manual, to help you check the connections. Just be careful to read the sections on precautions, to protect yourself and to prevent any other damage.This manual is also useful in that it lists all the compatible parts, so if the display is defective you could use this guide to help order a compatible replacement if you choose to do so.

How to turn off screen without passcode lock.

I just upgraded my wife's iPad 2 from ios 6 to 7. It used to be when you closed the ipad cover, it would turn off the screen right away. I would still like it to turn off the screen right away when the cover is closed (so as not to waste batteries) yet NOT require a passcode when opened again (just a slide of the arrow like it used to be). But right now, if I turn off the lock/unlock feature, and close the lid, the screen will remain full-on until the the auto-lock timer goes into effect - which will be never if I set it to "never".
I don't want to argue about the merits of having a passcode, I concede all your points, so there is no reason to tell me how stupid I am for not wanting to use one - but I would like to be able to have the screen go off without requiring a passcode to turn it back on. Is this now impossible? At the least, it should turn off the screen immediately when the cover is closed, and wait to put it in passcode lock mode until the auto-lock timer expires.
Is there any way to do this or is this just a case of Apple imposing this security feature our own good? Thanks.
-J

Wow. That was a super-fast answer. Thanks. I had seen that optoin and foolishly hadn't tried it because I thought typing my passcode there was just another way to put it into passcode lockdown "immediately". Well, I said I was stupid. Thanks, it does now work the way it used to and I can still have it require the passcode after a certain timeout period.

Turn off screen while apps run Need help

I'm running the SiriusXM app to stream music but I don't want the screen to keep after I choose my station. Does anyone know of a way to blank the screen? Is there a setting so when there is no touch activity it goes blank?
Also If you switch tabs it won't keep running the music in the background? I have a choice tunes or surf but not both?
Thanks
I'm here you wish you were too

You should be able to just tap the power button to turn off the screen. The app should keep running just fine.
If it doesn't, that's a problem with the app. I also have a music app in the Android Market and it is possible for the programmer to grab what are called "sleep locks" to enable the screen to be turned off without losing required resources like WiFi and the CPU. My app lets the screen dim, but not go off... however, the user can turn the screen off and the app keeps working.
