My 13" Macbook has a very dim screen. Replace inverter board or lcd screen?

I have a 13-inch Macbook and the screen display has gone extremely dim and is very hard to see. Should I replace the inverter board or lcd screen?

No dice I have it hooked up to an external display and can see that it isn't recognizing the battery. I've installed a brand new battery connector already, and this is the second battery (although they are from the same place, so maybe they had a bad batch?). I've done all the updates (firmware and Battery Updater) but still, nada. Any other suggestions?
I am not too familiar with this specific MacBook battery. When I push the button on the bottom, 4 out of the 5 lights come on, then the one in the middle, then they all go off. When I have it plugged in without the machine on, the light on the adapter is green. I start it up, and it goes to amber.
This is driving me crazy! What are the chances I would get two bad batteries? Or two bad battery connectors? Could it possibly be the logic board? I was thinking no, because it actually works fine without a battery and shuts off the backlight when the battery is plugged in.

My macBook has just a whitegrey screen with a blinking Question mark

My MacBook has just a whitegrey screen with a blinking "?". What has gone wrong? What can I do myself?
Thank you for suggestion

That may very well be the problem. Water and MBPs do not mix well. I hope it is not the case.
Going on the basis that you have Lion installed, boot the MBP using startup manager:

If successful, click on the recovery partition icon on the right.
From the 4 option menu, select Disk Utility:
Select Disk Utility>First Aid and run Verify and Repair.
What are the results?

My MacBook has become very very slow

My MacBook has become very slow for the last 2 weeks and often gets hangs with mail/address book applications. I have tried disc cleaning and permission repair but no change. Anybody has solution?

That confirms the hard disk requires replacement. There is nothing you can do about it until you return to school.
If you want to attempt a repair using your sister's Mac you need a FireWire cable with the proper connectors on each end. Connect the two computers, restart yours in Target Disk Mode by holding the T key as you start it, and run Disk Utility on your sister's Mac. The option to repair your hard disk will appear.
I don't believe the error you describe will be repairable.
If you have any information on the computer that you do not want to lose forever, copy those files from your computer to your sister's Mac. Since the disk is already damaged some or all of your data may already be lost.

My MacBook will not turn on and when I connect the charger it has a very dim light

I have just come back from holiday and went to turn on my MacBook, but it will not turn on
I connected my charger and the light is very very dim.
How do I resolve this? Will I end up losing all I have saved on it? Please help!!!

There may be something corrupted in the system, and a certain kind of reset may be able to help...
•Intel-based Mac: Resetting the System Mangement Controller (SMC)
http://support.apple.com/kb/ht3964
If that doesn't work, check instructions carefully and repeat if necessary, see about taking the computer to an Apple Store and try to call ahead for Genius appointment; or contact an authorized reseller with product specialists and service.
Some users ventured into their out-of-warranty macbooks to check the actual cables going from the battery compartment to the logic board, apparently some batteries unplug. Others you can't get into.
I see following post/link says several things, can't vouch for any except ^ the SMC reset support page above: https://discussions.apple.com/message/23996241#23996241 - Also, check the right side in this recent thread for links to similar topics.

With FW TDM, the failed computer can sometimes be powered up holding the T-key down, and a firewire icon would appear on the screen; then one could go about attaching or using a FW cable of correct type and connect it to another capable computer, then the failed computer's HDD would appear as an external drive. In the past, it was possible to clone or copy a drive from a computer that won't boot to another hard disk drive. Or at least copy stuff of that does not require the system to function along with the saved files.
Good luck & happy computing!

Macbook Pro very dim screen + inverted colors.

I picked up a 2006 Macbook Pro that was pretty beat up from a friend (probly dropped a few times.) The Macbook runs alright but I am having a few problems with the screen that I just can't seem to find an explanation for.
First, the screen is very dim. Not dark, as if the backlight was burned out, but dimmer than the lowest brightness setting on my newer Macbook. This is with the brightness set to the highest setting, it will get dimmer if I use keyboard key to adjust the brightness.
Also, the colors are inverted. Now I have triple checked the Universal Access settings and the colors are inverted when the setting is set for normal colors and the colors return to normal(although still dim) when the inverted colors option is selected.
As far as troubleshooting, I have hooked the computer up to an external monitor and it displays at the correct brightness and color settings. So, while the colors or normal on the external monitor they are inverted on the macbook.
I can provide pictures if needed, and can work my way around the inside of the macbook if need be. Any suggestions or ideas are greatly appreciated!

Thanks for the response!
I tried resetting the PRAM like you listed but that had no effect. I bought a new LCD inverter for my macbook pro to see if that could possibly fix the brightness problem, but the problem still persisted.
The previous owner had mentioned something of a overheating problem. I noticed nothing melted/browned on the logic board and all the cables seemed to be fine. I reseated all the connections to the LCD screen and the computer still booted with the same problems. I have not noticed any excessive heat problems with the computer since I have had it.
Also note, when the computer begins to boot and displays a white screen with an apple, it is just as dim as when the computer is running. Leading me to believe it is a hardware problem(I have also reinstalled the OS recently).
Tilting the screen to different angles and putting pressure on different parts of the back of the LCD does not make any differences either.
Thanks again for the input.

Very dim screen on MacBook Pro - how to prove it?

I bought an MBP about 4 weeks ago (just before the new rev came out, so this one does not have LED backlight) and have mostly been using it connected to a 23" cinema display.
When I was using the built-in screen the other day I realised it was very dim even at full brightness, with very narrow viewing angles, dark corners, and a noticable brightness continuity down the left hand side.
Now the shop I bought it from doesn't have any 'old' MBP's to compare it to, but comparing it to my 4 year old Thinkpad it's clearly substandard, and to my eyes it's bad enough to be defective. The shop on the other hand say it's 'normal' but suggested take it to an apple service center to get it tested.
So, does anyone know what the actual specs for light output (lumens) of a CCFL-backlight MBP are? If I don't have that number, how can I best persuade Apple that this screen is defective, and not get fobbed off with unprovable claims that it's 'normal'?
Many thanks for any advice.

My MacBook has become very slow to start up. What could be slowing it down?

My MacBook is now very slow to start up. What could be causing this and what is a way to repair?
Thanks, Chris

Hello Chris,
A variety of things could be causing the slow startup. The first place I would look is at the Login items on your MacBook to see if there are items in this list that are set to automatically start. Having applications automatically start will increase startup time. This article has the steps to do this:
Mac OS X 10.6: If items automatically open when you log in
http://support.apple.com/kb/PH6811
The steps from the article should work for Mac OS X 10.4-10.8; the only difference in Mac OS X 10.7 and 10.8 is that the Accounts icon is named Users & Groups:
To permanently prevent items from opening at login:
Choose Apple menu > System Preferences, and then click Accounts.
Click Login Items.
Select any items you don’t want to open automatically, and then click the "-" button.
If you are still experiencing a slow startup after that, you might want to try the steps in the following article:

I hope this helps!
Best,

3G, very dim screen when on, possibly no backlight? Otherwise functions perfectly normally..help please?

iphone 3g has been off for about a month. Bought a new charger as the old cable was a bit worse for wear. Phone charged fine and turned on fine, however the screen is very dim and can only be seen when held in the light. It's possible that the backlight has failed.
Other than the backlight it functions perfectly normally - I have tried restarting, restoring, backup and resyncing, hard reset etc. but nothing has solved the problem.
This phone is a replacement for a water damaged one that I sent back to O2 and claimed on the insurance, I hope I dont have to send this one back and get charged aother £50 excess
All help appreciated
Thanks

I'm sure there are things you could do yourself, but that would void your warranty. Give Apple a call and explain the problem to them, see if you can get it serviced under warranty. Thats what I would do.

Macbook has a very loud noise

When I turn on my Macbook Pro it has a very loud whirring noise. The noise continues for the whole time the macbook is turned on. Sometimes it becomes a little quieter but always is so loud my kids complain about it. The macbook is 5 years old but had a new graphics card/chip 2 years ago. The noise started about 2 weeks ago.
I took it to a genius at mac to check if the hard disc was failing and he couldnt diagnose any issue. Thought it might be the fans needed cleaning out.
Anyone got any ideas?
(I am constantly backing up in case the disc is about to fail)
Thanks

Yes, very likely, Ive seen endless clogged laptop and notebook fans ,......a lot of them were horrific
Dust and fuzz residue caked onto the internal fan
Dust bunnies and Fluffy’s fur
Your Macbook’s cooling system, including fan and rear vents pull cool air in from the back and (in the case of the Macbook pro) also from the left ports bringing this air around the processor, GPU, and heat sync and blow it out the back, as such your Macbook acts like a little vacuum cleaner of the air around you. If you use your notebook in a dusty area or around a lot of pet fur, this can quickly, even under seemingly ideal clean rooms, accumulate inside your notebook especially on the fan blades reducing its capacity for cooling and in a worse case scenario seize your fan due to caked on dust on the fan blades. Avoid very dusty areas or places where, over the long term you know fuzz, fur, or even smoke can enter into your Macbook.
Is it making a buzzing or scraping noise?
If you only hear it in a quiet room, that is normal.
noisy fan reasons:
A: you notice it more in a quiet room (the typical case) which is normal, all is AOK
B: fuzz and dust has caked onto the blades causing the fan hub to get off balance and make a buzzing sound.
C: fan rotor is going bad and making a whirring or buzz noise (rare).
D: Fan is spinning up due to excess heat from gaming, heavy graphics (typical, all is OK)
A and D are normal
B and C are not.
Do you use it in a dusty area or where there is a lot of pet fuzz? Laptop fans act like little vacuum cleaners and take in dust etc. from the ambient air around them.
If B and C continue for a long time (B is just a cleaning), they eventually cause the fan to either seize and/or die.
Good news, if that happens, and out of warranty, fan is a very cheap fix.
Bad news, if you let the fan die and continue to run same, you can overheat your unit and cause unwanted damage.

TV has gone very dim

Tv model: 40L2200U
After turning my tv the screen becomes very dim. Sound still works. I opened up the tv to see multiple capacitors leaking. There was a part i was not familiar with so i reasearched it and found it to be toroidal line filters. Im not sure if those need to be replaced too.
Edit: now i think the white substance is just glue so... i have no clue whats the problem now. I actually noticed that a few parts where missing.
If anyone can help with this problem, please provide any information possible.
Thank you.

Any more help I would be very thankful for.

Macbook has become very slow, i get the rainbow wheel whenever i click on something, i can barely do anything!

My macbook pro has slowly been getting worse over the last few months, it takes ages to load up when i turn it on, and whenever i try to click on something (google chrome, itunes, etc) i get the rainbow wheel for an unknown amount of time, its so slow! i can barely do anything on it, im having to upload this question on my ipod because i cant use my mac, ive had the mac for about 4 years, and i dont think its anything to do with the memory, any help would be very grateful!

Sounds like it might be your hard drive.
Go to Applications -> Disk Utility, select your hard drive, and click on the "Info" button and see what is reported for your S.M.A.R.T status at the bottom of the screen:

My Macbook has become very slow and unresponsive.

Hey, Just yesterday my macbook started playing up on me, before hand it was running fine.
It has started becoming ridiculously slow. Whether it's turning on, logging in or
just on the desktop it is extremely slow. Whenever I try to do anything as simple as clicking
on something the screen freezes and stops responding for a minute or so and gets the
"spinning wheel of death". I can still move the cursor (which is now the ball) whilst its frozen
but nothing else moves or responds. Once the mac starts responding again the same happens
over again if I try to do or click anything else.
I have tried cleaning up my mac, emptied the trash, cleaned the desktop etc. It still doesn't fix
anything. I have around 24g free of about 75g.
Please Help!

MacBook has a very slow internet connection.

I got a macbook pro two days back. It worked fine with my Beetel 450TC1 router for a night. I was able to download the OS update in half an hour. Sice then, the connection has been painfully slow- around 34 kbps. Other computers in my home network work fine. They were able to achieve a download speed of upto 2 mbps. However, when I connect my macbook to the network- either by ethernet or by wifi, they too start experiencing similar problems. I initially figured the problem must be with my Internet Service Provider, Airtel, and approached them. They gave up after changing the router a couple of times. I then tried the local istore. But the internet- wireless, worked perfectly well there. Probably because they have an airport extreme- I don't know.
Is it probably because of the OS update, which incidentally also included an airport update? I'm trying to figure this out. What do you guys suggest I try next?

hi.
have you tried resetting the router? Usually there's a reset button at the back of the router.
hope this helps.
