Screen keeps dimming when Tecra M5 on battery only

Hello
I have a Toshiba Tecra M5 laptop and when i take out the mains charger the display dims to the lowest brightness and i have to manually brighten it every single time.
Is there a way to stop this?
I have been into power options in control panel and i cannot find anything in there to fix this.
Any help would be greatly appreciated.

Hi
In my case the Toshiba power saver is appears in control panel only.
I dont need to go to control panel -> Power Options.
But in control panel -> Power Options you have to check if the Toshiba power saver is chosen in Power Schemes.
Furthermore the Power Saver icon should be visible in taskbar.
If this will not help you, then I recommend installing the Toshiba power saver again.
For that download the power saver from Toshiba European driver page.
Good luck

Screen goes dim when processor working - even when plugged to mains power.

Screen goes dim when processor working - even when plugged to mains power.
Whether I'm running 3D software or just surfing the net, the screen keeping fading/dimming and then recovering over a few seconds. No USB devices connected, mains power on - NOT IMPRESSED!
Any ideas - a hardware problem? Back to Mac?

If you go to System Preferences > Energy Saver, the is a checkbox under the "options" tab that says, "Automatically reduce the brightness of the display before display sleep." On my new MBP (10.5.1), this was "on" by default. Try unchecking it and see if it helps.

My screen keeps dimming automatically

My brand new Macbook Pro's screen keeps dimming the screen all the time regardless of which setting is it on. Its the first time it does that today and it's so annoying!!!! I have the following options: Put the hard disks to sleep when possible, slightly dim the display when using this power source, automatically reduce brightness before display goes to sleep and restart automatically if the computer freezes.... The only thing that is check marked is Put the hard disks to sleep when possible and automatically reduce brightness before display goes to sleep... Any advice? I googled a bunch of stuff but I don't have the options they give to help my problem such as un check the automatically adjust display or what not...
Thanks

You have to go to System Preferences > Displays (not Energy Saver where you were).
If you really don't have it, and you have an external display attached, that's the reason why. If that's the case, let me know, and I'll give you directions to do it.

My ipad2 screen keeps dimming and staying that way. And I can see the reflection of the app I most recently closed. Help?

My ipad screen keeps dimming and has ghost images of the previous open app. Can this be fixed? Help.

Did you ever resolve this issue? I have an iPad with a similar problem. After a software update the screen went very dim. I have just finished trying to restore the iPad to the latest iOS 8.1.3. The display is still very dim. The backlight does change when you adjust the brightness slider but at maximum brightness it is just barely possible to see what is on the screen. What makes me think this is software related is, like you said, there are remnants of previous screen images overlaying the current screen. For example, when I restored the ipod, I enter DFU mode so the screen showed the "Connect to iTunes" images. After restoring and rebooting there is not change but the "Connect to iTunes" images are still showing up on top of the normal screens. Even if I power off the iPad and turn it back on that image still appears as if it is permanently burned into the LCD. There are more previous screen images appearing underneath the current screen as well (e.g., I can see the System Settings window faintly under whatever screen I'm currently on). Would like to know if your problem required a new logic board, new LCD, or if you were able to resolve it with software tricks. Please respond if possible.

Why does my screen keep dimming and brightening?

I'm just sitting here in front of my fire during a mid-March snow storm in Maine, and my screen keeps dimming and then brightening. It's getting quite annoying. What is going on?

OK, I figured it out - it's the auto brightness adjustment. Found the answer in the pane to the right of my comment.

Iphone 4 screen keeps rotating when closing apps

It only started a few days ago but it's starting to get on my nerves. My iPhone 4 screen keeps rotating when I go to close an app, and it rotates back when I go back to the home screen.
I don't know why it's doing it, but was wondering if anyone did know. And if so how to fix it?
Thanks a bunch!

It's fixed nevermind..

RANT: Why does screen keep dimming even when "DIM" is disabled?

ARGH this is buggin' me!
I turned off the dim under custom in energy saver. i am reading a document and it keeps dimming and it's annoying as doo doo. anything i can do?

What about the option of "Automatically adjust
brightness as ambient light changes" in
Preferences/Displays?
William
William - anyone with this problem I can guarantee
shut off every screen dimming option.
I have this issue. It seems to be intermittent.
What seems to improve it - Restarting, or unplugging
and re-plugging in the mag safe charger.
These have been my only solution. I have even turned
off all display changes for battery power so that
there shouldn't be any "confusing" factors for the
computer.
I wouldn't care so much about this issue if it wasn't
for the screen whine with decreased brightness.
I trust apple will fix this with software or firmware
updates.
I checked my 1.67 PB 15", it does what is being described. Software?

Why does my screen keep dimming?

Screen on macbook keeps dimming after a few seconds, even when I put it at the brightest and I'm in the middle of using it.

If that doesn't help, perhaps this is your cause:

Screen Auto-Dims, when Auto-Dim is Off

I did the SL upgrade a few days ago on my 2008 MBP, I did a clean install. And now I've been noticing my screen will dim a few ticks from full brightness by itself while I'm working. My power is plugged in and I have made sure auto-diming is set off. ONce it dims I have to hit F2 to bring it back full. I never had this issue with 10.5

When does this occur? There is another option in the Energy Saver settings that will dim the display before it goes to sleep, but that doesn't sound like the problem you're having. Just thought I'd throw that out there as a possibility.

How can i keep the screen from dimming when reading sth.?

as above

Screen dimming is an operating system function; I'm not sure if any program can actually disable that.

Lcd screen keeping 'dimming'

I'm sure there is an easy fix for this.
I notice if i haven't used my computer for several minutes, the screen dims, and then quickly brightens againa as soon as i touch the trackpad or any keyboard button.
I have gone into the options listed under the battery icon. I have tried to set it to best performance, it still seems to occur, i have gone into custom and and energy saver and set the sliders for putting the screen and computer to sleep for both the battery and the power adapter to 15 minutes. I have locked the settings.
It still seems to occur.
Peculularly, i often go back into this area, and the lock is UNlocked again, without me entering my password.
Is the screen supposed to dim? I find it annoying and would like to turn it off.

I can understand your frustration with this, and with some of the responses...
Check out that link in this thread, I have outlined "improvements" to the situation in the last post.
There is no official solution, and apple did not address my question during my last repair.
I will be setting up another pro care session within the next month and will try to reproduce this for them.
Supposedly this has been going on since the Powerbook Era, and is nothing new. Unfortunately I've only noticed it with the MacBook Pro, and never with my powerbook.
Keep an eye out, and eventually we will find the source of the problem.
Now here's the REAL question:
Does anyone know if there is a log (say in console) of when/why/how the screen dims, much like there is a log of system sleeps???
I think that will answer our question, and find the source of our dimming despite all the appropriate settings UNCHECKED!

My iPod keeps showing the apple logo + a blank screen and the lock screen keeps freezing when trying to unlock it.

Last night I turned my iPod touch 4g off randomly and then when I went to turn it back on and went to unlock the screen it froze up right there and will not unlock to the home screen to where all my apps and all that are. Ever since that happened the iPod keeps showing the apple logo repeatedly, as well as a screen being completely blank when still turned on. Also when i plug in the iPod to the computer it recognizes it for a second but the iPod does nothing and shuts off and repeats in showing the apple logo and blank black screen. I can get it to the home screen where the slide to lock button is but every time i even attempt to slide it, it freezes up and doesn't do it.
I also having been trying to restore it by plugging in the cord and pressing the home button to get the screen with the usb cord to pop up but no matter what i do, it will not let me turn the iPod off period because every time i keep trying to do that it just shows the apple logo and all of what i said up above again. I have also seen it get a white screen to show a few times , which i assume means the white screen of death. I have never seen that screen before this happened.
I know this is not making any sense whatsoever but this is very hard to put into words in explaining. I have searched the internet but i can't find a single problem that sounds like this one in solving to fix it. The iPod is on right now as i'm typing this. I haven't attemtped to push the buttons down again to fix as i would assume maybe to just leave it alone as i sleep through the night in hopes of it maybe working or even dying. I've only had this iPod for 4 months now and i just don't understand why it won't let me turn it off completely or work properly for me to restore it.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Iphone 6 plus screen keeps dimming

I have recently updated to 8.02 and when I turn on my iPhone after a minute the screen dims itself automatically. I have brightness set at 100% and no auto brightness.
The reduction in brightness is no huge though is noticeable
Thanks

I have the same issue with my iPhone 6 running 8.0.2, it is very annoying. I have been on the phone with Apple about it - I hope it is fixed in iOS 8.1

Screen auto-dimming when I hit delete

I bought a 17" macbook pro for school three weeks ago. It is 2.5ghz, 4gigs of ram, 250gb hd and the high res scree. I upgraded from a 17" powerbook g4.
One thing I have noticed that really bugs me is that when I hit the delete key the display will dim as if I where to turn out the lights and it will light back up when I take my hand away. I only hit the delete key for just a second and it does this. It is quite annoying that I never had a issue with on the powerbook. I assume the light sensor is right around there but it would seem that apple would make it so it would take longer then a second of darkness to dim the screen.
I am sure someone else has had this issue as well.
Thanks,
-rob

Annoyingly, this feature re-enabled itself when I upgraded to 10.5.5 recently.
Re-disabling it was a bit of a pain, because searching for "dimming display" in System Preferences brought up Energy Saver prefs, but did not find this setting -- Google came to my rescue, of course.
