MBP - Power-up Backlight comes on ...thats it and freezes

I have an early 2008 MBP 15-inch. Warranty ran out 2 weeks ago (had it 13 months...). It powers up, makes normal noise, backlight comes on and thats it. It seems to freeze. Tried booting into diags and booting off CD but no luck. When I hold 'T' down I do see the firewire icon but thats it.
Graphics chip problem? Firmware hosed? System board?
Anyone encounter this?
Thanks in advance!

Welcome to Apple Discussions!
Did you realize you could have purchased AppleCare up to two weeks ago?
That would have extended your warranty another two years.

Hi, I have a Power Book G4 Tiger 10.4.11 and my problem concerns iTunes 9.2.1(5). I have changed my Apple ID and password recently. Since that, I am told when I try to buy something in iTunes Store that my "session has expired". Where does this come from?

Monitor backlight comes on briefly, then blanks out

I'm using a COMPAC PRESARIO laptop that's running WINDOWS XP. I've had the system 7 years & had a couple viruses that were supposedly cleaned up, but it was done by someone else so I'm not sure of this.
PROBLEM DESCRIPTION & CORRECTION EFFORTS TO DATE:
When the computer is turned on the COMPAC logo comes up, but soon blanks out, though not thoroughly on occasion, just goes real dark, with images faintly visible. Unfortunately, the behavior is not consistent, sometimes not lighting at all, other times as previously described, not visible at all, or visible up to WINDOWS logo page, then blank. If power is disconnected for 48 hours or better it will sometimes remain visible for a period of time, so long as it doesn't enter hibernation mode, though that trick hasn't worked recently; then the above problems repeat. I have connected a COMPAC FS7600 monitor to it to see if it is indeed a monitor problem, but that also blanks out after WINDOWS logo displays, prior to reaching log-in stage, the monitor power button going from the green it has while visible to the amber that signals a disconnect (I think). I've been forced to do hard shutdowns repeatedly, resulting in the "Windows encountered a problem with the last start-up" & have tried the "last working configuration" option, but that hasn't helped, so I'm at a loss on what to try next.
One of the answers here indicated the backlight could be replaced. If so, how would I go about that if it comes to that?
I am a freelance illustrator & writer, whose work & income depend on a working system, so I'm currently unable to produce the products clients desire; as such, this problem is imperative to correct. Any & all assistance will be greatly appreciated. Thank you.

Hello @darenderer ,
Welcome to the HP Forums!
I understand you're having issues with the display on your notebook going blank.
If the issue persists on an external monitor chances are the issue is not hardware related, though when it goes dim and is barely visible that does sound like a bad backlight which is kind of strange.
We can test this by trying to load the BIOS. If the BIOS loads and displays properly this would tell us the hardware is OK. To access the BIOS tap F10 while the notebook boots up. If this is displaying OK you may need to restore the default BIOS settings which is usually done with F9 while in the BIOS. You should see the keyboard shortcut in the bottom right corner of the screen to confirm this shortcut.
If the BIOS does not display you could be looking at a hardware issue. The issue being intermittent like this might suggest a bad connection to the backlight or display. You can see how to remove and reconnect these connections in the Maintenance and Service guide available in the User Guides section of your products support page here: HP - Drivers & Downloads.
It would help to know which product and operating system you are using. For information on finding your product and model numbers click here: How Do I Find My Model Number or Product Number? To see which version of Windows you are using click here: Which Windows operating system am I running?

Do you have a 15" mid-2010? If so then your problem is surely...
Mid-2010 15" MacBook Pros - the bad NVIDIA GPU
If you're having frequent kernel panics with your 15" mid-2010, or intermittent screen problems, the problem is, more than likely, the faulty NVIDIA GPU found in a number of those machines.
Here's just a sample of a kernel panic log that points to the faulty NVIDIA card:
Kernel Extensions in backtrace (with dependencies):

Here's the "official" Apple take on the issue - but the very real kernel panics need not be preceded by 'Intermittent black screen or loss of video'... in fact, you might not experience any video problems at all. Although video problems can certainly be a portent of things to come…
So what can you do? Print out a copy of your kernel panic and a copy of the Knowledge Base article and take them, along with your machine, to your local Apple Store or an Apple Authorized Service Provider. The unfortunate thing is that many people have passed the “three years from date of purchase” now and Apple is not honoring the free logic board replacement for many users. Some dealers seem to be making some exceptions for those past the three year mark, but don’t count on it…
Good luck,

Backlight comes on, but nuffin else.

Basically only the backlight comes on , Not writing at all comes up . I have done EVERYTHING in help section .. restored / reset 10x . updated. 5 r's . everything else.
I can plug it in , it recognises , plays music , but all i can see is the backlight ( NO writing or anything )

I can sympathize because I'm going through a similar problem. The only difference is that mine plays as long as it's hooked to the computer. About three to five minutes after it's disconnected I get nothing. Not even the backlight. Sad.

I am trying to print a document. The light comes on that the Cyan ink cartridge is out of ink....it is at least half full...i have shaken it, disconnected the printer from power source and the pc...still will not stop flashing. Oh, sorry...it is a hp business inkjet printer

It could be that the cartridge failed. Replace it with a new one and check.

My MBP doesn't have com.apple.PhotoBooth.plist

My Photobooth is acting up. It's a bit blurry looking. If I open iChat and look ath the webcam from there, it looks great.

sherrrrilyn wrote: ... My MBP doesn't have com.apple.PhotoBooth.plist
If there is no PhotoBooth.plist currently in your User / Library / Preferences folder, quit Photo Booth (if it is open) and re-launch it. A new PhotoBooth.plist will be created automatically by the Photo Booth app unless your software is damaged or has been modified somehow.
If you do not already know, the Library Folder is hidden OS X Lion. Use the <option> Key and the Finder > Go menu command to access the hidden folder as instructed here: http://support.apple.com/kb/PH4567

(1) Be sure you are testing Photo Booth in bright light. Using brighter light for iChat
      might make its pictures look better than Photo Booth.
(2) If more light does not help, be sure you haven't applied a Photo Booth effect
     that is causing the blur.
Launch Photo Booth, click the "Effects" button, and then click the center ("Normal") choice before you take a new test picture.
(3) If your Photo Booth test picture is still blurry, you may need to
     repair your Photo Booth app.
Use your Mac's Disk Utility to repair permissions and then download and apply the latest Lion Combo Update: http://support.apple.com/kb/DL1524
Repair permissions again immediately following the system restart that completes the Combo update.
Properly applying the Combo version of updates can sometimes correct software problems.
(4) If properly applying the latest available Combo Update doesn't fix Photo Booth,
     reinstall OS X.
Reinstalling Lion will reinstall all its component apps, including Photo Booth. If you need help reinstalling, see this article: http://support.apple.com/kb/PH3878

Because of low battery my iphone 5 got switched off and than its not starting by pressing the power button or by keeping it on charge. While charging a white screen comes for 2 second and goes away. This process continues till the phone is on charge. Please suggest how can I start my phone.

Hello Ritugor,
I would be concerned too if my iPhone was not powering on. I found an article with steps you can take when you encounter an issue like this. I recommend following the steps below:
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.

I cant download anything including Updates, when i try to download a black box appears saying that i have to power off the laptop using the button, and it freezes, so i have no option but to power off. Please HELP

I cant download anything including Updates, when i try to download a black box appears saying in 4 different languages that i have to power off the laptop using the button, and it freezes, so i have no option but to power off. Please HELP

Well, at least it's good that there are no hardware issues - that's a relief and one problem area that you can check off.
OK, so let's summarize so I can get a clear picture of what's going on. If you try to download something from your web browser, what happens? What if you try to download a small utility such as "EasyFind" from the App Store? Or is the problem specifically linked to downloading updates?
I'm just trying to get a feel for if anything really means anything?
Usually what you download from, say, a website, goes into your Downloads folder. It's the default folder for things like that. Apps from the App Store are downloaded to your Applications folder. And software updates are generally, I believe, held in a temporary folder so that they can be installed (in many cases) when you're asked to restart.
It could be something as simple as repairing permissions on your start-up disk. You're running Snow Leopard, right? (That's what your profile says.) Try opening Disk Utility from your Utilities folder, selecting your boot disk and try verifying permissions. If you come up with some errors, try repairing permissions. After that, go ahead and verify your boot disk - you won't be able to repair it at this point, but at least you can see if you have any errors.
Let me know about the anything and get back to me after you've verified and repaired permissions and verified your boot drive.
Good luck,
Clinton

My iPhone has suddenly stopped working. It now says the battery is dying and to charge it. After charging it for over an hour, there is no change. The power won't come on, and I am left with a blank screen advising me to plug my phone into the charger.

Try different USB Cable, try different Charger. Clean iPhone charging port with clean dry toothbrush. If still problem and you have Warranty or AppleCare, make Genius reservation and take iPhone to Apple for resolution. If no coverage, most likely it could be battery or charging port assembly that need replacement.

Keyboard backlight comes on in landscape mode no m...

I have an N97 and whenever the phone is in landscape mode the keyboard backlight comes on. It doesn’t matter if the phone is open or closed. This problem has been with us for a long time & obviously drains the battery quicker. Also when we watch movies on the device the Keyboard backlight stays on & its rather annoying. I would like to know if their are any remedies for this that I may not be aware of or how long we need to wait for a fix?
Also, the FM Transmitter Nag screens are very annoying. Most of us use the fm transmitter in our cars to stream MP3s to our head units. So 1 tap access is paramount. As things stand now its way too complicated to turn on the FM tuner and access our libraries. Furthermore the player keeps loosing its place so we are constantly having to:
1st.Tap the music player widget
2nd. tap the music library, choose last played (which never works!), Music library, music store or radio (99.9999999999% of the time I choose *library*).
3rd. Select either artist, albums, play list, all songs, pod casts, Gender or composer (I almost always choose *all songs*).
4th. now we see our selection and pick a song.
The Problem is many people do this while driving and even though some smart a** will pop up and say (you should never operate your phone while driving) I say “Of course I try to activate it before I drive But there is the occasional time I forget and It would be nice if you guys made My very expensive N series device act the part". I don’t think I’m asking for to much here. Just a small effort towards making the device function properly and more safely Is all I’m asking. Or Is that too much?
It would be nice if you guys made the Phone:
1.Stop loosing my Place. Every time I go to play a song I need to find a song.
2. Make the current play list accessible by tapping the album art like it was before instead of taking me to the volume.
3. Make it so that the FM transmitter can be turned on or off from the now playing window without popping into the fm tuner app or having to confirm that its activated or deactivated.
A simple on off will do & likely save lives & you guys from lawsuits.
Remember Nokia, your own words say that the N97 is not a smart phone. “It’s a *mobile* computer.” & the N designation makes it a mobile multimedia computer. A lawyer would have a field day with this.

Just what I expected . Not a single **bleep**ing responce. Nokia you are pathetic.

JH,
I don't have a 900 G3 iBook here (BTW 14 or 12"?)
What I do have is an 800 MHz G3 12" and the picture of the power socket is here:
http://tinyurl.com/b345hq
My trace out of the two points is here:
http://tinyurl.com/dhc2sq
Now I take NO responsibility for the accuracy of these two trace outs.
I have an 800 12" board and yours is a 900 ?" board.
This will give you an idea of how to do it.
Here's a long discussion detailing some of my methods to effect this repair.
http://tinyurl.com/d799xs
Note that my methods have evolved during this post. Toward the end I recommend the the use of "grain of wheat" wire. I like this a lot better, it's smaller and easier to handle than CAT 5 wire. It's also one wire. Not all grain of wheat wire will be like this.
So the other end of those two wires are attached to the original power contacts of the torn off socket and the normal plug is plugged into that. Proper insulation practice should be used. I use shrink tubing.

Under search in maps, names come up that aren't in my contacts. How does this happen?

Under search history in the Maps app,...along with all the other places I
did search for, some addresses comes up that I'm not familiar with, and they stay
there. In some cases I didn't search for them at all. Some I may have. A name also
appears, under the address, like "from John Doe". It’s a name that
I'm familiar with my email, but is not in my contacts. Why and how does
this happen?
For example, a person I receive emails from for work, came up as the
"from", and the address, after I searched for it (not on my phone).....I found out
it was the address of his company, I place I've never searched for, nor is
there a hyper-link to it any emails/websites that I could have clicked on
accidentally.
In another example, the beginning of an address “5165” which I may have searched
for and starting typing in came up in the history with several locations that
start with those numbers. Most of them say “from current location”, but one says from
a name, whom again I’m familiar with by email, but is not in my contacts and
have no idea of why the name would be somehow connected to the address.

Thank you for the reply. I really appreciate it. Do you know why the names are attached, as "from"?
I attached a screen shot image. "Harry" and "Angela" are not contacts in my phone. Who would their names get there?

When I try to use FaceTime on my Macbook Air, I try to verify the email I want people to call me with, and it says verified, but soon an message comes up that says "Could not verify the email address. Please check your network connection and try again."

So our school lets us use Macbook Airs for the school year, and it has facetime on it. I know facetime isn't blocked because like everyone else is using it. So I decide to give it a try. I click the icon, it says enter your apple ID. I dont have one, so I click to make one, and do so. I then enter my apple ID and click next. The screen reads "People will call you using your email address. What email address would you like to use?" I enter my email address in the box below the message, and then go to my email and click the link, and sign in, thus verifying the email. I go back to the facetime window, and click next. At the top it says Verified, but when I click next it doesn't go on to the next step, it simply blacks out the next button so that I can not click it, and after a few minutes a message comes up that says "Could not verify the email address. Please check your network connection and try again."
So that is the issue, please help!!!!!
*Note-I repeat that I know it is not blocked by the school because everyone else uses it just fine.*

Hello BassoonPlayer,
Since you are using one of the the school's Macbooks, it is quite possible that the time and date are not properly set on the computer that you are using. FaceTime will not work if you do not have the proper time zone set up for the location that you are in. This past week, there were a two other Macbook users I've helped by simply telling them to set the Date/Time properly. By the way, you described your problem very well, which makes it easier for us to help you. Hope this solves your problem -- if not, post back and I can suggest other remedies.
