After switching Equium U400 ON screen went dim

Hi,
Over the last week my laptop seems to have a strange problem! It was on standby and I opened, the screen lit up as normal for a few seconds an then went dim. Now this happens all the time, when its booted up the screen lights up as normal for a few seconds but then dims again.
I have tried taking out the HDD but the same problem occurs in BIOS. I have recently changed the FL Inverter but the problem is still there! When connected to a external source (HDMI) it is fine, but when the laptop screen is in use it just stays dim all the time, if I shine a bright light on the front of the screen I can just about make out whats displaying. Any help on this matter would be greatly appreciated.
Thanks
Zak

it can be a few things but based on my experience its a defective inverterboard.. they fry from time to time.. its the little board that supplies ur LCD screen with that massive amount of power it takes to create the backlighting.. if u attempt to replace it ur self keep your fingers at distance if its powered on.. theres huge ammounts of voltage in that little board .. pretty harmless as theres no current almost but its gonna light up your finger like a christmas tree :)
inverter boards is around 28 eur i guess and they are fairly easy to replace.. (but if ur not good with a screw driver take it to a authorized workshop)
but before u do this take alook at ur "dim switch" at the screen if there is one of those.. it could be dust or something else pushing that litte button down and that would keep ur screen from lighting..

Screen went dim even after sync

My iPhone 3GS had the screen go dim, where I can barely see anything (almost black). I've re-started several times. I've backed up to iTunes. I updated iTunes. Updated phone. Synced phone to iTunes. Then restored phone to factory settings. Still same problem. I can hear sounds, but can't see enough to even slide the arrow to answer an incoming call. Please advise. Thanks!

Equium U400 - Laptop screen becomes black

Quite recently, my Equium U400 laptop presented some problems when opening up. The light of the screen was unstable for seconds (flickering) and then the screen was loosing its light although one could see the desktop but in a dark "negative" way. It would take some attempts to close and open the lid in order that the computer switches to hibernation mode and then resume, to try to have the screen operating well.
The problem persists and I do not know if this is caused by a software or some conflict from windows or it is a hardware issue.
Any ideas?

When I switch on my laptop, the screen appears ok for 2 seconds and then looses the light. The start up process continuous normally. As I have noted, the desktop is visible but in a rather negative scheme, meaning that one has to look at it from a close distance and it is dark. So, by closing the lid the computer hibernates and after a while when the lid is pulled open again, there are chances that the screen would operate normally again. But it can take many times until it does so. \there has not been any change in my laptop apart form installing updates from Microsoft and no new software or hardware has been recently installed.

IdeaPad P500 screen went dim

I've searched around these forums and not been able to find a solution for my problem. Here's the whole story. I've had my IdeaPad Notebook P500 for over a year, and rarely had an issue with it. Today, I accidently touched the F11 key, which happens to be the "Brightness minus" key. Immediately, the screen went very dim, to the point where it actually hurts my eyes to be typing this. I can adjust the brightness sliders up and down on the screen, using both the F11/F12 keys and the slider box available from the "Brightness" selection under "Settings". Even though the sliders go up and down, the screen stays the same very dark level. Windows 8 64-bit is my OS. I have uninstalled and re-installed the Intel HD driver. I have shut down the laptop and turned it back on while holding the F12 (Brightness plus) button. Yes, it sounds crazy but someone mentioned it on another thread so I figured what the hell. It was useless, though. I have rebooted several times. Anyone have a clue as to why one simple mistype has apparently hosed my computer, and better yet, anyone know what I can do about it? Thank you.

Here is a cut and paste from another topic I found through laborious searching. My P500 is basically a Best Buy packaging of a Z500, so I figured I'd give this a shot, and it worked! Hope this helps others. khoofi

Upgraded to Windows 10 on Lenovo Ideapad p400 touch, screen went dim

Hello,I just installed the free Windows 10 upgrade on my Lenovo Ideapad p400 touch last night. I woke up this morning and booted up my computer, and everything was fine until I attempted to change the brightness. When I tried to do this, my screen went very dim, and now I can't adjust the brightness (and I can't read my screen well, either). Normally, I would install/reinstall the video driver in order to fix this problem (recommended for other users with similar issues), but I currently do not see a Windows 10 version of the driver I need on the Lenovo website.I was wondering:a) if/when a new driver would be available to install (if that's the recommended solution)b) is there something else going on?c) Windows 10 allows you to revert back to Windows 8.1 within the first month of use. Should I just do this?d) Is the p400 touch capable of running Windows 10? Why or why not?Thank you!

Hello. I also have a Lenovo Ideapad p400 touch. Screen also went dim on me. In Windows 8.1 just uninstalling graphic's driver worked. It was Control Panel, Device Manager and then Display Adapters. That doesn't work with Windows 10. The other solution of rebooting and press the increase brightness key at the Lenovo logo somewhat works but it doesn't turn the brightness all the way up. So I found this worked for me: Go here: http://support.lenovo.com/us/en/products/laptops-and-netbooks/ideapad-p-series-laptops/ideapad-p400-touch-notebook/downloads/DS031547 And just download and reinstall the old graphics driver for Windows 8. That finally got me back to maximum brightness.

My ipod nano 6th generation turns off after she tells me the screen is dimming than ipod goes off.

I wanted to know if there is someone at Apple that can give me some guidance on how to use my ipod nano 6th generation. I am not sure if I am working it properly or if there is something wrong with it.
I cannot get back to home page; I shut it off and on and it just stays on same page. I cannot take the voice constantly interrupting the song or functions;
When you set an album in play it will just play the first song over and over never going to next song. The genius interrupts and starts randomly playing different songs; when you select a song the voice comes and and tells you the screen is dimming and then seconds later it turns off.
I have tried to read the directions put the ipod won't allow me to follow.
Please help!

Is VoiceOver turned on? See here for more help on how to turn it off if need be.

After opening an email, my screen went black

my mom opened an email and her screen went blank. I recieved the same email everything was fine on my computer when I opened it.
Any thoughts?

Can you use
http://docs.info.apple.com/article.html?artnum=58583>Target Disk Mode to run Disk Utility on her machine? Or can she boot from het install disc and do it herself?
Disk Utility
   1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
   2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
      Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
   3. Click the First Aid tab.
   4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
   5. Select your Mac OS X volume.
   6. Click Repair. Disk Utility checks and repairs the disk.
Then boot back to your internal drive and use the internal Disk Utility to repair Permissions.

After downloading the update my screen went 1/2 black and I can't access the settings because I can't see

PPlease help

Instead of trying to restore through iTunes, use the Find My iPhone to your advantage.
Either go to www.icloud.com and perform a remote wipe of the device via FMiP, or download the FMiP app to another iOS device and do it from there.
A remote wipe will also restore the device back to factory settings.

Screen remains dim after waking up on virtual terminals

I am having a strange issue when the display gets dim and won't get bright again, but only when I am no a vt.
I have an older (~4 yrs) Dell Studio 1737 with a Mobility Radeon inside with the xf86-video-ati driver:
$ lspci | grep -i vga
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV635/M86 [Mobility Radeon HD 3650]
$ pacman -Qq | grep xf86-video

$ lsmod | grep radeon

i2c_algo_bit 5391 1 radeon
i2c_core 22479 6 drm,i2c_i801,drm_kms_helper,i2c_algo_bit,radeon,videodev
When I leave my computer on one of the virtual consoles (vt2 - vt6) and it is idle for (I think) 10 minutes, it gets dim (via DPMS, I guess?) . However, I can't make it go bright again - after I move the mouse (which I am not sure makes any sense since I have no mouse in the vts) / press any key, nothing happens.
Now, the strange thing is, when the light is right, I can just see the text, but it is very, very dark and unreadable. Under normal circumstances I can see nothing and the screen can't be told apart form a blank black display. Actually, I had thought it was blank for a while until only recently, when I had the Sun shining against the display.
I wrote a simple script whose name is 'b':
echo 10 | tee /sys/class/backlight/acpi_video0/brightness
and I left the console as root (!) for 10 minutes (!) and when the screen went dim I called 'b' and nothing happened. I have no other ideas about how deal with this one - I tried reading and looking around, and have pretty much nothing. Does this problem ring any bells? Does anybody know how this can be fixed (apart from "just don't leave it on the vt for longer than 10 mins" or similar ;d - these have occurred to me already). Of course, if you need any more information about my hardware, I will provide it.
I am running a constantly updated arch.

It also seems to be related to later OSX versions, like 10.8.x & 10.9.x

Shuts down after start tone and grey screen with pin wheel...!???

Hi all, first time here so please bear with me,
even though i have had my imac for so long now, i have only in the last three to four months started playing around with it, i really am a newcomer to macs, and pc's come to that! so far i have only connected up to the internet and put a couple of home video's onto dvd, and play music.
i have been reading a lot of the other posts and frankly i'm lost!
it is about 20 months old and was bought in the uk, i live in cyprus and for that reason i did not purchase an apple plan.
we do not have an apple store here although there is an apple dealer, however they are not soley apple and over here service leaves a lot to be desired! so i am reluctant to take it to them as they are likely to just keep replacing parts and eventually present me with a huge bill!!
anyhow this is the problem:
several times the screen went dim and froze, with a message saying to "push the power button to switch off and and then switch on again", it seems this happened each time when i opened azureus? after this happened a few times it would no longer open the desk top, it would load normally,ie. grey screen with pin wheel followed by blue progress bar and then just a blank blue screen, the blue tooth mouse however was still connected as the cursor would move. it has now changed again! start up tone and grey apple screen with pin wheel for about 30secs or so, then the fan seems to go into turbo mode for a few secs before switching off....i feel sick!! i was really getting to like my mac.
i did recently install tiger, but there were no problems at all with that and it is running on a friends apple with no problems at all, more recently i added more memory which coincided with when i started using torrentspy and azureus,
i did read in another forum something about possible memory probs, so i followed the tip to remove the memory and the back up battery and leave the computer unplugged for 24hrs, i replaced the battery but not the memory, i'm still getting exactly the same shut down result.....
can anyone shed some light on this pleeease? i'm feeling rather desperate right now.....thanks.

Hi ino,
My suspicion is that you have serious hard drive directory corruption caused by the crashes when using azureus.
First step is to see whether you can boot up from your Mac OS X DVD . Put it in the drive while its on, and start up the computer again while holding down the "c" key. The computer should now start up from the DVD.
Select the language you wish to use, and then choose "Disk Utility" from the menu bar (which menu it is in depends on which version of OSX you are using).
Your HD should appear in a panel on the left hand side of the window which opens. Select it and then click on the "repair disk" button in the right hand section of the window.
If Disk First aid is able to complete the repair now click on the "Repair permissions" button.
Once this process has been completed try restarting the computer.
If it still doesn't work, you may have to try an "archive and install", while booted from the OSX DVD.
Be very wary with software like "azureus".
Cheers
Rod

TS1286 My iPad went dim, then locked up... now it won't restore

My iPad was functioning flawlessly until just a few hours ago when the screen went dim, not dark just dim and the unit locked up completely. I rebooted it with the home key sleep button, it restarted then after a few minutes did the same thing again.
Screen went dim and it locked up.
I connected it to iTunes where it recognised it in restore mode and tried to update the software.
I got an error code of (9) which had something to do with the USB, so I tried another port and restarted iTines... it updates the software and I was int he process of syncing all my apps back onto it from iTunes when it froze again.
Even iTunes froze...
I had to unplug the iPad and shut down iTunes and then restart it.
I tried to reboot the ipad but it would restart and get tot he black screen with the apple logo and just stop. I shut it down and now I can't even get it to reboot to the black apple logo screen.
But when I plug it into iTunes, iTunes regcognizes it as an iPad in restore mode, but once I click restore it starts installing the software then gives me a error code of 1600, which is USB related.
I've tried all the trouble shooting reccomendations on the support site and nothing...
Is my iPad dead?
Why will iTunes recognize it in restore mode yet I cant even get it to reboot/restart by holding down the home key and sleep button?
Help plz!

Monitor on Equium U400 is inverted

Started Equium U400 and screen is now inverted, believe it may be the inverter or backlight in the monitor.
Would appreciate any assistance in trying to, either find a solution to fix it or suggestion of a place to buy the correct part for my laptop.
Many thanks
Clark

hi thebear2006
as i am reading your posts correctly with the magnifier and changing colors to inverted everything is ok?
try this:
- deinstall grafics driver
- restart and install the newest one
- after this restart once more
if this not solves the issue maybe another application is causing this strange behaviour.
i dont think ist hardware related because you can change colors...
the inverter provides the power for the light tube, if it is broken you have no more backlight but you still can see a dark picture on the screen.
naybe you have to recover to get rid of that....
rarely it could be a broken wire....

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.

Windows 8.1 Update Causes Lost Brightness Settings / Screen is Dim

I updated from Windows 8 to 8.1 and the next day my screen went dim and I could not adjust it neither with the keyboard +/-, nor with the onscreen graphics dashboard, nor within the power settings.
How do you fix it?

Sometimes Windows updates will break your graphics driver. That is because Intel and NVidia do not update their graphics drivers on the same schedule that Microsoft
updates Windows, and sometimes the updates are incompatible and cause the graphics driver to do wonky things. In my case that came in the form of lost brightness settings.
I searched these forums for a fix and I could not find one, so now that I know the answer, I am sharing it here.
How do you fix it? You have to reinstall the graphics driver. This is how I did it.
I found the graphics driver install file that was already on my computer and I ran it. It reinstalled the driver in about 5 seconds and my screen brightness functionality was restored.
Where is my graphics driver install file? On my computer it is here:
D:driversVGAIntelx649.17.10.2932\Setup.exe
Yours is probably in a different but similar location depending on how it was installed and what brand it is, etc. I have a Lenovo
P400 touchscreen laptop with an Intel HD 4000 Graphics.

How do you prevent screen from dimming while on power adapter?

I don't want the screen to dim while I'm connected to the power adapter. In the Energy Saver module, it is optimized for better performance, which sets the following parameters:
-set to sleep when inactive (never)
-put the display to sleep when computer inactive for 30 minutes
Nevertheless, after periods of inactivity, the screen will dim (not sleep). I can't seem to stop it from doing so. Any suggestions?
YoungTurk

There are two things that will dim the screen - the Energy Saver and the Ambient Light Sensor.
In the Enerygy Saver panel select "Options" and then there is a check box that you need to uncheck. Since it is one the Options screen you may have missed it.
With respect to the Ambient Light Sensor, I think it should remember your settings once you set a brightness.
