I have been experiencing a problem lately. Once a while my MBP '10 screen will have a sudden drop of brightness and then back to normal. Does anyone have similar problem?

My macbook was running at basic, normal speed, nothing too serious for a year-old laptop, but suddenly one day, my performance dropped sharply, to the point where it would take up to ten minutes to attempt to get to a page, and songs would freeze for about a minute about 3 times per song in iTunes. It all started when I attempted to import a CD into iTunes (it was downloaded onto my HD, not imported directly from a CD), and I got the message "attempting to copy to the disk macintosh hd failed. The disk could not be read from or written to." About this time, my computer started acting unusually slow, (the problems mentioned above).
I did some looking into this, and did both suggestions listed here (Disk permission repair, then manual iTunes folder permissions change):
http://discussions.apple.com/message...623410#7623410.
After this my problems were eased for a little bit, I was even able to import the folder I had been unable to import earlier. But I tried then to import the very next CD (it was an 8-CD set), and then I got the same error. Thinking it was possibly a problem with a corrupted/infected file, so I ran a scan through my whole computer (using McAfee), which didn't return any problems. Then, on top of this, my mac suddenly stopped burning CDs, saying that the CD failed because of a "medium write error."
The brightness goes up when you plug in your MBA, but then over time it just goes up and up. I honestly like my brightness pretty low (rarely more than half, typically at 3-5 notches), but it just keeps on going up and up. I almost never set it above half, but multiple times a day, I notice that it looks pretty high and it's at like 3/4 so I put it it down to about 1/3, but after a while, it's just up again.
Anyone else notice this? What is it, why does it do this? How can I fix it? I don't mind not having auto-brightness (even though I loved it), as long as my screen doesn't keep going up.
So I installed Vista 64 bit on my Macbook Pro (Santa Rosa), I installed most of the drivers I can find, but I cant get the screen brightness buttons to work (F1 and F2)
View 2 Replies View RelatedUnder normal office lighting, I find anything other than 100% brightness seems too dark. But I've been getting huge amounts of eye strain so am wondering whether to turn in down some more, say to 50-75%, but worried that will strain my eyes even more. What do you guys have your 13" set to, assuming good ambient lighting?

My iMac has just gotten all grumpy and weird with me, when attempting to browse anything on the internet (or even trying to access the router via 192.168.1.1) everything is ridiculously slow or just doesn't load. At first the speed went down dramatically - i went on speedtest.net and did a test, the page took a good 5 mins to load and after the test it turned out that i had a speed of 0.2 Mbps (my average speed on a good day is about 2.5 Mbps, shocking i know!) Ive tried turning the computer off and restarting it to no avail. Im doing this on my Macbook Pro which is sat next to the iMac and with a speed test is coming up with speed of about 2.2 Mbps, so its clearly the machine and not the internet/router. Ive tried using Safari, Chrome and Firefox they all provide the same, unusably slow responces.

View 2 Replies View RelatedHas anyone noticed a very slight flicker on their new MBPs? I have a new 13" and, every so often, the screen brightness dims and then brightens very quickly (happens in less than a second).The option for auto-adjusting the screen brightness is off so it's not that particular function.It's most noticeable on all-white backgrounds both on AC and battery power. Hard drive access doesn't seem to coincide with the dimming.
View 17 Replies View Relatedlately, my mba has been behaving a little weirdly. its screen would suddenly become a little dimmer when the brightness in the room has not changed a bit. after a long while(15 min?), it'll turn brighter again by itself, and again without any change in the lighting of the room. the change is not big but obviously. any idea? can it be some software? or setting? or a defective light sensor?

View 1 Replies View RelatedI don't know if it depends by a latest update I did to Itunes but after an uncertain amount of time my MacBook Pro 2.2Ghz Santa Rosa start to flicker. I have posted a video in youtube [URL] so you can see what happend. For a small amount of time while flickering is started the mouse can move around then it stuck and lock me out of the system. I have to reset many time PVRAM and SMC then it will restart until it lock it down again. It worked flawlessly until yesterday after if I don't remember wrong one or more software update. I use Snow Leopard (official licence). I downloaded the Combo Update for Snow Leopard and ran it. I still have to test it again. Since I need to do some work in the next 48 hours I can't full test it. After the hard reset an image pop out and It won't let me start up the system again ever if I reset many times PVRAM and SMC Then I use bootcamp to "unlock" the MBP. I do run windows under BootCamp. It will run but I can't see anything since the video remain black (I hear the HDD until stop working) Then I push the power down button and I turn off the windows Then after a long time it will log into Snow Leopard! I'm getting crazy the last two days
View 24 Replies View RelatedMy Macbook Pro display all of a sudden went to the 'white screen of death' as I've heard others refer to it as. I've tried zapping PRAM, resetting SMC etc. to no avail. When I connect an external monitor, I am able to use the Macbook without problem, so I know it is video card/controller/display related issue. I'm going to send the Mac in for repairs. But before doing so, I'd like to erase my hard drive so I'm not sending them all of my data with the computer. I've done a time machine backup, so all is fine there as well.
My problem, is that in order to erase the hard drive, I need to boot from the OSX install disk. No matter what I try, I can't do this with my external display. If I insert the disk, and hold down the C, my Mac never recognizes the external display plugged in and so I cannot see to get to the disk utility tools on my OSX install disk. I've tried using Command-display dim button, to no avail.
I've tried simulating a clamshell mode boot where I close the lid as soon as the boot starts (with the OSX install disk in the drive) and I get a kernel panic every time. Even if I didn't, I don't see how I can close the lid at startup and hold down the C key at the same time.

To begin with, I own a MBP Intel Core Duo 2.0/2 Gigs of ram. I've had this laptop for roughly 18 months and do not have Applecare. I take extreme good care of all my stuff and still baby it till this day. I have NEVER bumped the laptop against anything, accidently dropped it too hard on the desk or anything similar along the lines. Essentially, looking new. About 2 days ago, I was working with my laptop and I closed the lid which made the computer go to sleep. Everything all normal & no appearance of anything! Around mid-night, I opened the MBP's lid to check my email. (Computer awakes, I can hear the Superdrive awake) then boom, a blank screen. The monitor did not turn on then burn out, it was always off. Similar to if you dim your monitor all the way. I can still see the desktop however, there is no light. If I take my flashlight and point it to the desktop, I can see everything. I called a few places, and they described it is the Inverter board or could be the fluorescent bulb that is damaged. My reasoning for the inverter board is faulty is because when a fluorescent bulb goes out it, it tends to flicker at first. Researching this forum, I noticed most MBP users LCD's that go out, they flicker but, mine just went out and I can still see the desktop. Where can I order the inverter board? I tried [URL] but they're out of stock. I will change the inverter board myself because it will be quicker and I need to use my laptop. It is currently hooked up to an external monitor until I can get this fixed.

View 24 Replies View RelatedRecently, after about 5 minutes of use (not sitting idle), my MacBook's screen will go very dim. I hit the buttons on the keyboard to take the brightness all the way up, but it doesn't get much brighter and there's only one thing that I can do to make the screen go brighter: I go into System Preferences and click Display. The second I click that, the brightness returns without me doing anything in the Display section, so after Display comes up, I just close it out and the screen brightness is fine for a while. It seems to do this after the lid has been closed for a while and then starts dimming again after opening the lid and using it for about 5 minutes. Is there a way to fix the auto-dim mode without disabling it? MacBook (white) is running Leopard 10.5.8 with all the latest updates.

When I push the brightness key on the keyboard, the appropriate image comes up on screen and goes to full brightness, but the actual brightness of the screen doesn't change and the lack of change is reflected correctly on the brightness slider in System Preferences.

View 1 Replies View RelatedI have the aluminum MacBook (<3) and it is often found on my desk, in front of my aluminum desk lamp. I was writing a paper and had one hand on my touchpad and touched my (off, but plugged in) light with my other hand. My screen dimmed just a little bit, approx the brightness between the two highest lighting levels. Even when not touching my touchpad, just touching my light, my screen did the same thing. Depending on WHERE on the lamp I touch, it affects the brightness... but only on the bell surrounding the light bulb, no other components of the light.

I tried my F1 and F2 key and the Nvidia Control Panel, either of them is working. I installed all the drivers from the CD and it can actually show the icon in the center(bottom) of the screen when I hit the F1 or F2 Key. However, the brightness adjust does not work,the screen stay the same.

View 5 Replies View RelatedI have a macbook and a screen plugget to it. Now I use just the new screen and don't use the macbook one. But every time I turn the mac on the macbook screen turns on, and I have to decrease the brightness manually every time. (cause it's a waste of energy to keep it on if I don't use it). So I'd like to know to set the screen brightness to 0 by default, so I don't have to turn the brightness down every time.
