View 8 RepliesHas 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.

I know the battery has to be full. This just started happening last night. Also, I just had the hard drive replaced and I've only had it back for a couple weeks.

Also, can one continue using a macbook laptop if the battery is dead, but run it through or plugged into an ac outlet all the time?
MBP plugged in, lid closed, using external monitor only. But when I unplug it, it immediately goes into sleep mode and doesn't wake until I open the lid.
View 8 Replies View RelatedMy Macbook shuts off immediately when unplugged and will not start up unless it's plugged in. This just started last night...I was using it while it was charging and then unplugged it when it got to 100%, and it immediately shut off. Prior to this, it seemed to be charging and running fine. It also runs fine plugged in.
I did some searching and tried some of the suggestions I found...shutting down, taking the battery out, holding down the power button for 5 secs, and replacing the battery...making sure the connectors were clean, downloading battery update, etc. Nothing helped. I also read an article about how the lithium polymer batteries will just quit suddenly like that instead of running down gradually. So I'm hoping all I need is to buy a new battery. But my question is this: Since the system profiler shows the battery health is "good," does this indicate something else is the problem? Or will it still show it's good after it completely dies?
Here are the stats according to System Profiler:
Charge Information:
Charge remaining (mAh):3955
Fully charged:Yes
Charging:No
Full charge capacity (mAh):3956

I am just now learning about these things, so apparently 1047 cycles is a good life for the battery. I just want to know that this is the only problem so I can order a battery and be done with it. Wish I could run it over to the Apple store and have them check it, but it's an hour and a half away, so if I do that, it'll have to be later in the week or next week. Naturally, I don't want to be patient and wait.
I have a macbook mid 2007 that shuts down immediately after it is unplugged from AC. I've tried the battery on another machine and it works fine as well as trying a known good battery in this machine.Also I've tried a known good AC adapter. Other things I have done are run the hardware test which shows no errors, reset the smc and Pram, repaired permissions etc. the battery appears normal in the menu bar and says it is fully charged.Also it Appears in system information as normal.coconut battery also appears normal with 275 cycles.I'm hoping the problem lies in the Battery Connector with Sleep Switch and not the logic board. Anyone had any experience with this problem?
One other strange thing is that after unplugging the AC the system shuts down immediately, but once you plug it back in it starts without the power button being pressed.
My iPod Touch only turns on when its docked on my radio/ipod dock but will immediately turn off as soon as I take it from it. It won't even turn on and sync when connected to my macbook. The iPod has never had battery problems or anything else wrong with it.

While running a PC game on battery, Vista operating system would just shut down unexpectedly. If the machine is plugged in, it would work fine. Currently the problem is getting worse; when I boot up into Vista on battery, it would shut down in about 2-3 minutes.
Initially I thought it was a battery problem. I booted up into Leopard and checked the battery information in System Profiler. I didn't see any problem. 332 cycles and condition is "Good." In addition, Leopard works just fine on battery.
several months ago when my ibook g4 was just over a year old it began suddenly going to a blank screen when the battery was fully charged and the computer was unplugged. Sometimes i would hold down the power button and the computer would come back from seemingly having fallen asleep. other times i would have to plug the computer in and hold down the power button for it to come back. to do this it would make this whirring fan sound before going from a black to a gray screen and then finally re-starting up from the beginning. a box would then appear telling me that my date and time were set wrong and that this could cause some functions to behave erratically. this despite my having frequently changed the date and time zone back to my own and locking the settings. the computer keeps switching the date back to 1969. and now when i put a dvd into the computer it just spits it back out and won't play it. long story short...i am beginning to hate my mac. what's the point of a laptop if you have to leave it plugged in for it to work. apple tech support has done nothing to help me and has refused to admit that the g4's have a problem despite my having read about tons of people having these exact same problems after a year. i read something about how in denmark this consumer group proved that there was a faulty part attached to the battery coming loose and that they were suing apple.

I made the mistake of unplugging and removing the battery from my iBook while in sleep mode, to reinsert a screw I found on the floor. Now at startup it's stuck on the blue screen. I've tried several resets, icluding shift-command-option-power, zapping the PRAM command-option-P-R which got my "startup sound" back, which I let chime 3X, I reset the NVRAM, single user mode confirmed the clock was reset (to 1904) and an fsck said the system "Appears to be OK." I've had no luck with "safe boot," I have no reset button and no OS disk to boot from. Verbose mode prints up the same 10 lines over and over "(error) imprt: importer start failed for 89, invalid destination port, no such file directory, run loop could not be started." It's a 14" iBook G4 running OS 10.5.6. I don't mind if files are lost-there's nothing important on there.

When I tried lowering the volume it doesn't work. Then I tried using the play button to start my itunes and that doesn't work either. I don't know what I did wrong. How can I get it back?

I have a late-2010 MacBook Pro running Bootcamp 4.0 with Windows 7 64-bit. My graphics card is the nVidia GeForce 320m. I looked online recently and found that there was an update available for my graphics card (previously I had the one that comes with bootcamp, which is from 2009 I believe--quite outdated you see). So I installed it, hoping for better DX11 support, etc... It installed fine, but now my display is stuck on 100% brightness, when before I could adjust it with the F1 and F2 keys. When I try using the keys it shows the Apple popup with the slider moving, but the brightness doesn't change. I went into Control Panel > Power Settings and tried adjusting it from there, with no luck. The nVidia Control Panel doesn't have any satisfactory controls to do this either. It must be, of course, that the driver update changed things, but I'm not sure how to rectify the situation. I uninstalled the Apple Driver-Display from Control Panel and then re-installed from the Bootcamp files, but it didn't help. I've heard some talk about Apple Cinema Display, but I'm not sure if that's the same thing as the Display and whether I should be looking for a driver for it.

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.
Is it better to keep the charger in after a completely charged or pull out the charger. Basically I'm wondering if the power is pulled from the UPS after the battery is completely charged or is it still constantly charging the battery.
View 3 Replies View RelatedI usually have my Air at full brightness. I notice after a while if I leave it alone the screen dims a bit. If I move the mouse it is slightly dimmer and I have to manually adjust the display back to full brightness. Is there a setting turn this off? I have automatically reduce brightness of display before sleep turned off for both the battery and power adapter setting.

I've read on the net that the batteries that come with apples charger are sanyo eneloops.
Does this mean i can buy a pack of eneloop batteries and they will work with my charger?
My new macbook aluminum's screen has a tendency to gradually dim and then brighten on it's own, randomly. This is off the battery power and not AC adapter. Anyone else's macbook screen do this? This is not the screen dimming to sleep. it is constantly dimming and brightening, even as I type this post.
View 18 Replies View RelatedI've just purchased a new macbook air 11.6 in and when watching movies (not in ful screen) the screen dims, Im assuming because of inactivity with keyboard, etc. I don't like to watch all movies in full screen, so how do I change the settings to allow for longer 'inactive' times? Meaning, I don't want the screen to dim after only 5 minutes.

My f1 - f12 keys have seemed to adopt a new function. When i use f12 to increase the volume it will also act like i am pressing f1 and simultaneously dim my screen. When i press f1 to dim my brightness it will also increase my volume. When i press f2 to increase my brightness it will also "press" the tilde key and vise versa. These are only a few examples and it seems that all my f1-f12 buttons have adopted a secondary function.

My screen dims after no use for about a minute. I have it set to do that after 15 minutes. I minute is too annoying (like if watching a video or something with no user input). Anyway, how do I make it stop doing this. It does not seem to want to go with the 15 minute setting I put in for screensaver.
View 3 Replies View RelatedWhy is this? Can I stop it from happening? I just put the brightness all the way, plug the MagSafe back in, unplug it and it is back to being dim?
