HP dv7 black screen lights flickering
Hello,
My HP Pavilion 7-2100 with Windows Vista doesn't start up well.
If I press the on-button I can hear the notebook and there are to lights of the num-lock and caps-lock flickering and the screen is black.
Could anybody help me please?
PS: My English isn't very good,
so if I said something unkind: I'm sorry!Hi @BennyJ ,
You would be able to check this by connecting a monitor. If it shows then that is possible to do a system restore from there.
Thanks.

I just got my MacBook Pro shipped back to me from apple repair, fixing my keyboard light. When turning on my keyboard light, I noticed that it flickers on and off for a couple of times, and then starts working. This seems to be affecting the auto brightness on my screen as it changes brightness in sync with the keyboard light flickers. I noticed that the right speaker area has some light leaked onto, and I'm thinking that the light leak is messing with the light sensors in the macbook. I recorded a video of it happening, but sorry about the quality, I recorded the video using my phone. I took a picture of the possible light leak on the right side speakers. You can only see the brighter parts, but i'll repost a better picture once i find my digital camera.

-edit-
Here's a picture i took using my digital camera, I hope this one helps you see the light leak: http://www.flickr.com/photos/rodrigokim/3681007546/
It's getting pretty ridiculous as to how many times I've been going to the apple store. If I have to go in again for this, it'll be my 3rd time there for the past 3 weeks regarding my macbook pro.
Any help/advice/suggestions are appreciated! Thanks!

Shadowy light flickereing above home button on ipad mini
I have an iPad mini and it was purchased in December. Since yesterday I noticed a shadowy type light flickering at the bottom of the screen just above the home button. I have no idea what this is and hope somebody has an answer? I am very concerned about it, thank you. When I put my brightness on high the shadowy light is not visible, however as soon as I put the brightness down the shadowy light becomes ovious and noticeable.
it might because you have pressed the button a little too hard and caused a dent in the display inside or something. take it to the apple store, since if you didn't press hard and there's the problem, they can give you a new one.

MacBook Screen is Flickering (comp. is 5 1/2 years old)
I got my MacBook in June 2007. A few months ago, the screen began flickering whenever I'd move the monitor back and forth. At first, it would go out completely (the only way to see what was on the screen was to shine a bright light at it) and I'd have to wait and open the monitor bit by bit in increments with a few minutes in between each time. Now it just flickers when I moved the monitor forward and away from me. I'm pretty darn sure (about 97%) that it's to do with the inverter cable. How much do you think it'll cost to get it replaced? Or does apple even make parts for a computer as old as mine?
I agree with your diagnosis of the inverter cable. Apple or an AASP can do it for you although I don't know the price. You can do it yourself if your up to it by following the guide at http://www.ifixit.com/Device/MacBook
Or you can send it to a third party such as http://www.techrestore.com/ -
Macbook pro screen freezing/flickering peripheral failure
Hey guys
I use my Macbook Pro both at home for music production and live as an instrument. Recently I have been having problems, but for some reason these have never materialised at home - only in the live situation. I shall try to give as much info as possible, but I'm no use with Macs having been raised with windows machines.
Mac OS X 10.6.8
2.5 GHz Intel Core 2 Duo
4GB 667 MHz DDR2 SDRAM
I have around 13GB free HD space
It is second hand and therefore I have no idea about warranty. I have had the machine for over a year.
I THINK it's a 2008 17" model, although I am not sure.
Peripherals at home:
Digidesign Mbox 2 - USB
USB Mouse (third party)
M audio Oxygen 8 V2 keyboard - USB
HD TV as a second screen - DVI - VGA adapter
Live:
Novation Nio 2|4 uadio interface - USB
Novation Launchpad - USB
M audio Oxygen 8 V2 - USB
(Software wise I a running ableton 8 suite with izotope stutter edit. I average about 6% cpu usage)
Recently, my audio interfaces have begun to fail, but only in the live environment. I can switch the Mbox for the Nio at home and there are no problems whatsoever. 2 shows in a row this had failed, so I made sure to test all the equipment extensively. After 2 days of using the Nio as my soundcard using a different USB cable and slot, I assumed the problem was fixed.
On friday night we were playing a show, and mid set the screen froze with glitchy sections - looked like someone had broken the matrix. The screen began flickering in and out very fast in a strobe like fashion. My peripherals were still working fine, so I continued with the show in the hope that I could just control the session from them. Moments later, the audio failed, ad the system eventually cut out. I attempted to buy time and boot up again, but the same thing happened almost instantly.
Now that i've had a chance to get home and try it out, it has been working for hours at a time until eventually doing the same thing. I have found that most the time my usb mouse will remain responsive, yet I am unable to click on anything. Again, the sound generally keeps working, but one by one the peripherals fail. The screen flickering has only been temporary in the home setting, and does not sustain throughout the failure.
I'm generally poor with electronics, but the general consensus seems to be that it may be some kind of electro magnetism/static/I don't know effecting it live? I have never had a single problem with the machine until now. These failures have occured both running on battery and from mains power.You may be right that a part of the problem is due to external electro-magnetic interference, but could also be heat build up, and the fact that at home it runs for hours before an issue starts, heat is probably a part of the problem. If you can, stop by an Apple store genius bar and let the techs run some diagnostics, explain what is happening and see if they can isolate the issue. You may want to leave it with them for a few hours and let it sit there and run to see if heat is an issue.

Screen light auto turn dark when I use program/web with background dark in windows 8.1
Hi there,
I used HP Pavilion dv6t-6000 CTO Quad for 3 years.
CPU: Intel core i7-2630QM
GPU: AMD Radeon 6490m
It build in windows 7 and I manual install ( fresh install ) windows 8. It's fine. But when I upgrade to windows 8.1, it have an issue and I really hate it.
When I use "Sublime Text" ( with background is black ), the screen light is become darker. And when I back to ( e.g: a website with background is white ), the screen turn back to lighter.
I tried many ways, included 4 ways here but it's NOT WORK.
NOTE: When I used Option 1 ( upper )
1. Open PC settings, and click/tap on PC and devices on the left side
2. Click/tap on Power and sleep on the left side, and turn on or off Adjust my screen brightness automatically on the right side under Brightness.
==> It's NOT SHOW button "Adjust my screen brightness automatically". It mean: I have NO built in auto brightness sensor.
I think this issue is about AMD driver or Intel Graphic driver.
Is anybody have idea???Hi @kolz,
Welcome to the HP Forums!
It is a wonderful place to find answers and solutions!
For you to have the best experience in the HP forum I would like to direct your attention to the HP Forums Guide Learn How to Post and More
i grasp that after updating your system from Windows 8 to 8.1 you are having an issue with the display going dim.
You have tried some steps you located on the web but there was no change.
Windows 8 an 8.1 are not supported Operating Systems for your notebook. This does not mean they will not work only that HP has not tested it and therefore does not supply updated drivers. You would need to check the manufacturer's site for any updated drivers.
Downloading or Updating Software and Drivers for HP Computers
When I checked the driver page for your notebook I did notice there is a bios update, have you done that?

As a bios update does have a potential to cause damage I suggest contacting HP support for assistance with that process.

how can I retrieve data from my old powerbook? It's screen lights up, but displays only pixelated blankness. I have a second powerbook and a firewire cable....
It would probably be correct to assume that both PowerBook computers are equipped with FireWire. The article below could possibly be of interest to you. With a bit of luck, the old computer will be recognised.

Otherwise, it may become necessary to open the old PowerBook and remove the hard drive. The drive can then be connected to an appropriate external USB adapter, and read via another Mac.

Just turned on my ipad 2 wi-fi , black screen lights up to lighter black but I cant see a thing on it... does anyone have any ideas on what's wrong with it?
Try this First... No Data will be Lost...
Press and Hold the Sleep/Wake Button and the Home Button at the Same Time...
Wait for the Apple logo to Appear...
Usually takes about 15 - 20 Seconds... ( But can take Longer...)
Release the Buttons...
If no joy... Try a Restore...
1: Connect the device to Your computer and open iTunes.
2: If the device appears in iTunes, select and click Restore on the Summary pane.

I have upgraded itunes on m computer to 10.5. When I connected my iphone to the computer I was told that ios 5 is ready to be downloaded, and that I should back up my iphone before doing the download. I did. Now I want to get my iphone back on and it just can't . The screen lights up, i select language and network but it tells me that my phone cannot be activated because the activation service is temporarily unavailable. what do i do?
Try a Hard Reset.....
Press and hold the Wake / Sleep button AND the Home button at the same time, keep them both pressed until the Apple Logo appears on the screen, it can take 10 or more seconds. Ignore the swipe to turn off message. -
My Apple TV is not responding anymore and white light flickers
My Apple TV does not respond anymore and white light flickers all the Time. No connection anymore.
In that case if you've already tried unplugging from power, waiting for a minute or so and restarting and nothing helps, you probably ned to factory restore via iTunes:

When I press to the left of the home button, the screen lights up
When I press to the left of my home button, the screen lights up as if I were pressing the actual button. This causes Siri to pop up randomly all the time and my phone keeps accidently taking screen shots. Should I take it in?
I was a little confused when I first read this, but I think I understand what you mean now. The bottom left part of the glass on the front of the iPhone, by the home button, can cause it to act like you're pressing the home button. I do not experience this issue on my iPhone 5. This is probably a small defect in your iPhone. It isn't major, though, I'm sure if you visit the Genius Bar in your nearest Apple Store, you can get advice from the experts on what to do.

Screen Lights up while I'm on a call
Why does my screen light up when I'm talking on my Iphone4? I keep muting, hanging up, putting tne person I'm speaking with on hold....this is extremely annoying and makes me regret buying this phone! Why is this happening? What should I do?
I never think of myself as suffering from the proximity sensor issue but the truth is that on the odd occasion that I don't have my bumper on my phone I do sometimes mute the call with my cheek. This never ever happens with the bumper on the phone.
