Screen dim / Wake up

A couple of nit pick things...
One is the screen dimming, sometimes it does it with the option even being turned off. I know about the work-around but I was wondering if anyone came up with an actual solution to this.
When I wake up sometime the screen it black. I close it, wake it up again and its. fine. Also sometimes the password entry box will pop up again while I am entering my password. Come to think of it there are a lot of time I will try to type something in a text box and it doesn't get the first few letters in there. Anyone have any suggestions? Not huge deals but they can be annoying at times.

A couple of things I would like to add...
Firefox seems to act up after a while, wondering if anyone had suggestions on having it run more smoothly.
When I leave my desk and unplug my USB hub iTunes says my iPod is still connected.
Again, nit pick things but wondering if anyone had any suggestions. I have Cocktail and have it clean up the system about once a week.

Pre time stops "working" when screen dims/locks

the time on my pre stops "working" when the screen dims/turns off - what i mean by this is that when I wake up the phone the "old" time (time that i last had the phone awake) displays and then quickly updates to the current time.
The worst part about this is that alarms will not work because it does not know the real time when the screen is off!!
If the phone is on the touchstone everything works fine
can anyone help!!!?
thanks, Gavin

Hello Gavin and welcome to the Palm forums.
What trouble shooting steps have you tried so far? Have you tried restarting the phone? Reloading webOS using the webOS Doctor tool?

Macbook Pro Screen dimming

I recently inherited a MacBook Pro that I had previously bought for another person. They never used it much. Upon attempting to do anything with it, I'm finding that the screen won't stay lit, at least not by much. I can go into the system preferences and brighten it, but each time I wake or restart it, it has returned to a dimmer setting. Once, I awoke it from sleep to find the screen completely black, although a on-off sequence (couldn't see to do a proper restart) returned it to at least a dim setting. Any ideas? Thanks.

Hi,
Just noticed the last few nights my screen going dim. It is plugged in to power, the option for ambient light is checked in System Preferences.
If the room is the same lighting conditions why would the screen dim? In fact, if the room is getting darker wouldn't the screen tend to get brighter and not dim.
I have had the machine a few months (June 2009), and only recently in the last 2 nights noticed the screen is dimming. My concern is that there is something wrong with the display, since I never noticed this behavior before.
If I put my finger over the video cam the screen gets brighter.... guess the light sensor is right next to it.
Your thoughts... do you think I have an issue?

A magazine's app on my iPad has stopped working. When I open the Newsstand folder and click on the app, the screen dims briefly, then returns to the Newsstand folder. The other app in my Newsstand folder (Wall Street Journal) opens without any problem.

A magazine's app on my iPad has stopped working. When I open the Newsstand folder and click on the app, the screen dims briefly, then returns to the Newsstand folder. The other app in my Newsstand folder (Wall Street Journal) opens without any problem, and this magazine's app opens just fine on my wife's iPad.
I have deleted the app and reinstalled it from the Apple store and that makes no difference. I have also done a hard reboot on my iPad with no result.
Any thoughts about what might be wrong?

Hey everyone in Apple world!
I figured out how to fix the flashing yellow screen problem that I've been having on my MBP! Yessssss!!!
I found this super handy website with the golden answer: http://support.apple.com/kb/HT1379
I followed the instructions on this page and here's what I did:
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
I went through the 6 steps above twice, just to make sure I got rid of whatever stuff was holding up my bootup process. Since I did that, my MBP boots up just like normal. No flashing yellow screen anymore!!
(Note that I arrived at this solution when I first saw this page: http://support.apple.com/kb/TS2570?viewlocale=en_US)
Let me know if this works for you!

Guide to Upgrading to Windows 8 on the T540p (+fix for brightness/black screen on wake)

Hello all. I recently received my new T540p running Windows 7. Although I probably would have qualified for receiving Windows 8 recovery media from Lenovo, I went ahead and did the upgrade myself since I had a copy of Windows 8 laying around (and because I'm impatient). I'm fairly tech-savvy and expected the process to go smoothly; boy was I wrong. I decided to write up this little guide after having a thoroughly annoying time upgrading in the hopes of saving someone else out there from the hassles I underwent.
NOTE: The most troublesome part of the whole process was figuring out why the screen brightness was no longer adjustable and the display would not turn on after waking from sleep (black screen) after upgrading to Windows 8. Skip ahead to step #9 if that's the issue you're having.
Step #1: Make a bootable recovery disc or USB drive
This is important in case anything goes wrong during the upgrade or you decide you despise Windows 8 and want to bring back Windows 7. The T540p comes with a recovery partition in the hard drive (like most laptops nowadays I assume) which allows you to completely wipe your computer and reset it to its original factory state (the same as when you first received your computer). This is normally done by restarting your computer and hitting the enter key to interrupt normal startup and selecting the recovery option from a menu. I wrongly assumed that I would still be able to conduct the recovery after installing Windows 8, but for some reason after upgrading I was unable to start a recovery from the recovery partition. Thus it's important to create a set of recovery discs or a recovery USB drive yourself BEFORE starting the upgrade. Lenovo includes a program which makes this step very easy; see this page for details: http://support.lenovo.com/us/en/documents/ht004960
Step #2: Uninstall certain programs BEFORE upgrading
I skipped this step because I forgot about it. I haven't noticed anything adverse (aside from the brightness/display problem which I assume is completely unrelated), but Lenovo does suggest to uninstall certain programs before upgrading so it's probably wise to do so. Here's the list:
    - DisplayLink Core Software
    - Intel(R) USB 3.0 eXtensible Host Controller Driver
    - Lenovo Solution Center
    - RapidBoot
    - ThinkPad(R) Bluetooth with Enhanced Data Rate Software
See this page for details: http://download.lenovo.com/lenovo/content/windows8/upgrade/think/notebook2_en.html
Step #3: Download and save wireless drivers to external media BEFORE upgrading
After upgrading, I discovered my wireless didn't work and thus I couldn't connect to the internet. I wound up downloading the wireless driver to my phone and transferring it to my T540p. You could also use an ethernet cable to connect to your wireless router or cable modem. But if you have a USB drive, CD, DVD, external hard drive, whatever, save yourself the hassle and download the wireless driver ahead of time. You will need to know the brand of the wireless device (Intel or Realtek); look it up in your email receipt or from the Windows Device Manager under "Network Adapters". Mine was Intel. After figuring out the brand of your wireless device, go to the T540p drivers page here: http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t54... Look for a drop-down menu that says "Component" and select the option "Networking: Wireless LAN" (LAN, not WAN!). The page will refresh to show only the wireless drivers. Select the Windows 8 64-bit driver that matches your brand (I'm assuming all T540p laptops are 64-bit. If I'm wrong, please correct me). Download that sucker and put it to on the external media of your choice to use later!
Step #4: Begin Windows 8 upgrade
You'll obviously need to have a valid Windows 8 key or purchase a copy of Windows 8 for this step. I had a valid Windows 8 key that had been used on an old computer which died (hence my new Lenovo), so I reused it. This requires Windows 8 to be activated by phone which isn't nearly as scary as it sounds. We'll get to that later.
There are two ways to do upgrade: use a Windows 8 installation DVD or download a web installer. I had a Windows 8 key from a previous web installation and went with downloading a web installer. If you have an installation DVD, just insert it and get started. If you prefer to download a web installer, go to this page: http://windows.microsoft.com/en-us/windows-8/upgrade-product-key-only I think product keys are tied to either Windows 8 or Windows 8.1, so select the one that you have a key for and download the appropriate one. If you're not sure, you may have to try both.
During the upgrade, you will be asked whether you want to download updates (I assume this updates the installer) and afterward you will be asked to enter your product key. For some reason, when I downloaded the updates my product key would get rejected. I just restarted the Windows 8 installation, skipped the updates and then my product key was accepted. I don't know if this is tied to the fact that I was reusing a Windows 8 key (again, which had been used on a now dead computer) but if you find your key getting rejected then you may find skipping the updates helps. If this doesn't work and you're using the web installer, try downloading the other web installer (e.g. if you're using the Windows 8.1 web installer and find the key is rejected even after skipping updates, your key may actually be for Windows 8 and you should try downloading the Windows 8 web installer).
The installation itself should be a fairly straight-forward process. There are lots of guides online in case things go awry. If you have any trouble or errors, you should hopefully have made recovery media for worst case scenarios where you need to start from scratch.
Step #5: Install wireless driver & connect to your router
You should now have Windows 8 up and running on your system, but no wireless. Now's the time to use that driver you downloaded earlier. Install it and you should now have wireless access. Connect to your router and get online so we can start some badly needed updating!
NOTE1: your touchpad/trackpoint/keyboard experience will be especially funky at this point. That's because the drivers for them haven't been installed. Normally the touchpad won't be active while you're typing, but because the drivers haven't been installed you'll notice you'll accidentally move the mouse or click while typing (e.g. when entering passwords). Not to worry: this will go away when we install the Lenovo drivers now.
NOTE2: your function keys won't work (adjust sound, adjust brightness, etc.). That's also because of the drivers.
NOTE3: you may notice your screen's brightness may not be adjustable even from the Windows menu. Again, that's also because of the drivers. Hang in there!
Step #6: Activate Windows
Now that we're connected to the interwebs, it's time to activate Windows. If you're completely new to Windows 8, here's where you go:
-move your mouse to the upper right corner then move down
-select "Settings"
-select "Change PC settings" at the bottom
-select "Activate Windows"
This is where you'll enter your product key. As I've said before, my product key had already been used on an old, now dead, laptop. Reusing a key requires you to do a phone activation. If you find your product key gets rejected, go to the phone activation option and follow the instructions. An important note: at some point you will probably be asked how many devices/computers you installed Windows on. The correct answer is "one"; if you accidentally give another number, you'll need to call again and start over. (I'm assuming you're not doing anything illegal. As far as I know, there's nothing wrong with you reusing your key so long as you're no longer using the old computer Windows 8 was installed on, e.g. when that old computer no longer works. But if you're trying to install Windows 8 on multiple computers and you can afford to buy a new copy of Windows 8, shame on you. It takes a huge team of coders and support staff to make a product like Windows happen; help them pay their bills by purchasing a legal copy of Windows 8. Students can even get a copy for less than $70 with proof of student status. http://www.microsoftstore.com/store/msusa/en_US/pdp/Windows-8.1-Pro-for-Students/productID.288769600...
Step #7: Install Lenovo-specific updates and drivers
I typically hate all the crapware and bloatware companies include with new laptops, but Lenovo does make some which are useful. Their system updater should take care of downloading the rest of the drivers you'll need instead of having to download them all individually (with one exception: the graphics drivers may require a separate download later). Download the system updater here and keep running it until there are no more updates to download: http://support.lenovo.com/en/documents/ht080136
Step #8: Install Windows Updates
Load up Windows Update and start installing. If you're completely new to Windows 8:
-move your mouse to the upper right corner then move down
-select "Settings"
-select "Change PC settings" at the bottom
-select "Update and recovery"
-click the "Check now" button to check for updates
-click the "View details" text link to see the available updates
-click the "Install now" button to begin installing immediately
(Yes, the Windows 8 interface is dreadfully unintuitive unfortunately. Watch some Windows 8 tutorials on YouTube if you find yourself having trouble. Already looking forward to the next version of Windows!)
You'll also want to download the Windows 8.1 update if you installed only Windows 8 (the update to 8.1 is free). The download is available from the Windows Store.
Step #9: Install graphics drivers (if you're having display problems: unadjustable brightness, black screen on wake from sleep)
As I stated earlier, this was the most frustrating part of the installation process. My T540p came with only an Intel HD Graphics 4600 card, but it seems some others include a dedicated NVIDIA card. Whatever updates were installed with Lenovo's System Updater and via Windows Updates didn't seem to do the trick. I even updated the driver with the latest from the Intel website to no avail.
The solution, at least in my case, was simple: go to the T540p driver's download page and download the graphic card drivers appropriate for your system. Go here: http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t54... Look for the "Component" drop-down menu and select the "Display and Video Graphics" option and download the Intel and/or NVIDIA drivers appropriate for your system. (I have no idea what the Intel Wireless Display driver is for, so I avoided it thinking I don't need it)
BONUS Step: Go to ninite.com to download commonly used programs
Shameless plug for one of my favorite websites. It lets you pick from a list of commonly used programs, then downloads and installs each of them all automatically (and skips all toolbars/extra junk downloads). Makes getting started on a new computer a breeze!

Hello Yolanda,
a) I noticed that I can´t install MediaCenter on Win8, but just on Win8 Pro.
b) My problem is, as described, that installing "MediaCenter" on either "Win8 Pro" or "Win8.1 pro", though the "Media Center" key is accepted,
which I once 2 years ago downloaded on ANOTHER "Windows 8 Pro" computer, for free as it was a gift of Microsoft at that time - You could reserve = get up to 5 Media Center licenses per "Windows 8 Pro" computer for later use
on OTHER "Windows 8 Pro" computers - but never used ( i.e. NEVER USED FOR ACTIVATION ),
but after the first reboot, I am running "Windows 8 Pro with Media Center" WITHOUT LICENSE, as shown in the system screen.
Neither my "Windows Media Center Key" nor my "WIndows 8 Pro key" is then accepted to change the situation - I mean the keys I entered just before during the installation process of "Windows 8 Pro" and "Windows Media Center".
I am shure that I did not use the "Windos Media Center" key, as I have a list of personal keys I got for free from Microsoft, and I marked those 2, I used for other "Windows 8 Pro" computers.
So fact is, that with my brand-new computer, 32 Gigabytes of RAM, 4 Cores, "Win8 Pro" installed, I am forced to avoid the installation of "Windows Media Center", though I got valid licenses.
So your answer was not quiet helpful, as it does not change anything.
Sincerely
Rolf

Screen dimming

hey, i'm going to hook my macbook to my HDTV via the DVI adapter and then HDMI to the TV. My question is this: My Macbook has a screen dimming function, whether it's plugged into a wall socket or not after a short time of no operation the screen goes dim. Will the screen of my television go dim?
If so, how can I avoid this issue? I'm using Tiger and there seems no way to adjust this setting.

thanks for replying Simon. I have answered my question in a way. I don't know if the television set will dim but I've found out how to stop the dimming on the computer display in Tiger and on Leopard. You are right it's in Energy Saver settings. Uncheck the "Automatically reduce the brightness of the display before display sleep" this is in the options menu in Energy Saver. Then put the sliders on 'Never.'
Thanks

Blank screen on wake up !!

Been facing issues with the wake up feature since i bought my 13" mac air 2 weeks back .. sometimes when i open the lid to wake the machine up from sleep it either freezes on me or throws a blank screen .. the machine becomes completely unresponsive and am left with no other option but to reboot .. happens almost every other day , very frustrating .. called apple care and they looked clueless .. i know many people are having the same or similar issues with the instant on feature , anybody found a solution yet , or does anybody know if this is a software or hardware related ?

That sounds exactly like the issue I had. I assume it's some sort of software thing, but the Genius Bar just replaced my machine. I've seen reports of it here and on a few other sites.
What happened with mine is that about 50% of the time, when the computer (not the display) went to sleep, it would display a black screen when waking up. The backlight was on, as the Apple logo on the top of the lid lit up. Sometimes it would eventually turn on. Sometimes it required a keystroke. Sometimes it required powering down. A few times, it was difficult to get it to start up even after it powered down.
I had "SmartSleep" on my old MacBook Air, so I thought that might be messing it up, but it kept doing that even after I uninstalled it.
So far, I haven't had that issue with my replacement MacBook Air. BTW, my first one was acting up right from the start, so from my anecdotal evidence, it seems you either have this issue or you don't.

Shaky screen on wake up?

This started two weeks ago..The screen is shaky and is pixelated on wake up. Sometimes it stops and other times I get the black restart box. I have reset the PRAM and reinstalled TIGER. Any ideas. Once the machine restarts it is fine until it sleeps again.

Screen dims and multi-language "restart" message appears

Currently, every time Safari is used, the entire screen dims and a multi-language (German, Chinese, etc.) message comes on the screen saying that I must physically power down my machine and restart. No error message is given, nor are any other options allowed, as the keyboard and mouse are rendered useless.
I have rebooted the machine several times, including powering down the cable modem, but the problem persists.
This problem has occurred in the past, but seemed to clear itself, only to reoccur starting yesterday (23 Sep 05). I can't shake the feeling that this problem is more in the OS X arena than in Safari's, but testing does not seem to bear out my feelings - all other installed applications appear to run properly and this phenomenon of screen dimming with forced power down and restart does not occur with other applications.
Any thoughts? Thanks! Bob Meyer.

I suggest the following:
Repair the Hard Drive and Permissions - Mavericks, Lion/Mountain Lion
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
If you continue to have the problem, then reinstall the OS X Mavericks 10.9.2 Update (Combo) updater.

IMac 24" Aluminum screen dims like notebook

So this is kinda weird. For some reason if I do not do anything for a minute (move mouse, touch keyboard) the screen dims like on the notebooks when they try to save power. Something tells me this isn't right... Anyone have any ideas or experiencing the something?

Google: [10.4.12 ?|http://www.google.com/custom?q=10.4.12+?&sa=Search&client=pub-626330033301395 7&forid=1&ie=ISO-8859-1&oe=ISO-8859-1&cof=GALT:%23008000;GL:1;DIV:%23336699;VLC: 663399;AH:center;BGC:FFFFFF;LBGC:336699;ALC:0000FF;LC:0000FF;T:000000;GFNT:0000F F;GIMP:0000FF;FORID:1;&hl=en]

External screen dims when opening different apps?

Hi All ----
Seems my external screen dims and rectifies when opening different apps - like some kind of brightness adjustment going on... it doesnt happen on the MBP, just on the external screen --- i've checked all possible settings on Ext. Displ. / re-booted / repaired perms... cant quite figure it out.
I dont think this is energy-saver related.
Many thnx for any help in adv. ---
cheers,
J.

The problem with that is, it's hard to put it back together without assuring that you're not pinching the cable again.
Instructions can be found here.
As he says, the cable can be found at Small Dog Electronics:
http://www.smalldog.com/product/43417
If you need replacement feet, they can be found at MicroDoc.
The specific link you need on PowerBook Tech's website can be found here.
If it looks like too much for you to handle, you may want to check out DT & T Computer Services. Perhaps in a metropolitan area like Austin you can check the Yellow Pages and find a technician willing to match the price.
At one point, DominionTech in Colchester, Vermont was offering the repair for $79.90, but I'm not sure if that price is still available.
Good luck.

Screen dimming issue (?)

Hi, sometimes, (usually when web surfing) my screen dims on its own, at first I thought there was a problem with the screen, but then I realized that the brightness meter does go down, and raises again if I press the brightness button, BUT when its going down, the brightness does NOT display on screen, it just goes down... Also, it is like crazy drastic, it just dims enough to **** me off, like a few notches, very annoying, its been driving me crazzy since I bought it just never thought to ask anyone for help... Any ideas how to fix this?

Go to System Preferences Hardware Displays and uncheck the box for "Automatically adjust brightness as ambient light changes".
Then go to the Energy Saver and uncheck "Slightly dim the display when using this power source" for the Power Adapter and the Battery selections.

Screen dimming without selecting it to do so!!

Hi, I am a Macbook newbie and am sorting through some teething issues. The latest is that I have selected in my power setting 'custom' this selection has delays of 35 mins for screensaver and 40 mins for screen off. Now my question is this,I have NOT checked the 'dim screen before screen off' selection, but after 5-8 mins the screen dims down. moving the mouse puts it on full again..
I know it should do that on battery but this is on AC and on my own custom setting...
Any insight?
Also one more question, why does firefox display selection boxes in a crappy square manner whereas Safari (which I cant use as it is incompatible with a lot of websites) has nice little rounded glowing blue boxes?
weird
Steve

Well that just makes my macbook crazy then!! I really do not understand the dimming when NOTHING is selected for it to do so.. anyone else have dimming?
Oh and regards to safari, it does not work with yahoo mail, my university peoplesoft network thing, and nearly all of the major companies I have been applying to in the last few weeks (final year at uni!) one even required WINDOWS XP I had to go and use the cluster down the road to do their online test...
Firefox covers most of the problems apart from the last one.
Although it seems to load images quite slowly on our 10mbps lan...

Screen dimming delay . . .

I upgraded my iPhone 3G to 4.0.1 (quick and painless unlike the 4.0 release which was 9+ hours) last night and have noticed this morning that the time it takes for the screen to dim (before eventually turning off) after a period of inactivity has dramatically reduced. I can't remember the time that it took before as it was quite a lengthy delay, but now I reckon it's a period of approx 40 seconds before the screen dims. I think it used to be a couple of minutes. Has anyone else noticed this? Also is there any way to alter this timing (just like a MBP or iMac display in the Energy Saver System Pref Pane).
As always, any advice appreciated.

Neil was correct - auto-lock controls how long before the screen dims, followed shortly after by the phone locking. Passcode lock is a separate function. If you set auto-lock to never your screen won't dim. I suspect it's set to 1 minute at present =0)

Screen Dimming Setting Problems. . .

Wondering if anyone else is experiencing this: In system preferences energy saver/options I have checked "automatically reduce brightness of display before sleep." The problem is that if I don't check that - -which I would prefer not - - my screen goes dark after about 60-90 seconds of inactivity. My ideal is to not have the screen dim and then go to screensaver but apparently there is no way to do this.
My question:Do others have this problem? If you solved it, how? All suggestions appreciated.
Thanks!

I talked to a product specialist from Apple (through Applecare after waiting for an hour!) and he acknowledged it is not supposed to behave the way you and I are describing. He sent m a little program that does a "data dump" which I then emailed back to him which he sent on to the engineers, and they are supposed to get back to me the next couple of days. We'll see.
Obviously, you're in the same boat. I find it totally obnoxious to have to touch the trackpad every minute or so to keep the screen bright. Major glitch.
I'll post again if Apple solves this one. . .
