I calibrated my battery last week and I'm pretty sure I'm getting worse battery life after the fact. Has anyone had this experience? Can battery calibration hurt your battery?
View 12 RepliesI calibrated my MacBook Pro battery and then noticed that the battery life seemed slightly shorter after that. I calibrated it according to this: [URL]
Just wondering if I have done anything wrong...
One more question... What do they mean by "At this point, save your work. Continue to use your computer; when the battery gets very low, the computer will automatically go to sleep." Does it mean that I have to use the computer until it just shuts down or should I shut it down once the "Low Battery" warning pops up?

I've got an early 2008 Macbook Pro and, recently, I've noticed that the fan (fans?) begins running from the moment the computer is powered-up. iStat tells me that both fans are running at about 2000 rpms, though I only hear a slight whoosing noise from the left side. I don't remember the fan running constantly, and I have noticed that my battery life seems worse than normal recently. Is this normal, and something I just haven't noticed until recently?
View 6 Replies View RelatedI just read how to calibrate your battery, and I found out that I've been calibrating my new MBP 13" battery pretty much every day (unintended). I've been using it quite heavily since I got it last week... charging it fully, and reconnecting it to the charger whenever the battery hits somewhere around 10%.. Is this good or bad ? Should I charge it whenever it hits 50% instead ?
Apple says we are supposed to calibrate it once a month. Is it bad if you do it more often ? Any thoughts on this ?
I've done everything correctly that the apple described 'bout calibrating and its not lasting even 2 hrs. All I do is surfing. I have the brightness just one block. No keyboard illuminate. Bluetooth is off and for me to get 'round 2 hrs. I gotta keep closing the macbook's screen.

I will leave it running on battery power when i leave for the day, and let the battery drain/discharge fully through the night.I will hook it back up in the morning to have it fully charged, may be 30 - 60 mins after it being fully charged, i will pull the power out and run the laptop the whole day on battery.

Point 4. Says the computer will automatically go to sleep and then point 5. Says I should turn of the computer. Isn't it the same of the computer stays in the sleep mode?

is battery calibration as simple as fully charging and then draining battery ,or is there more steps?

so ive had this 13"uMBP for a few months now and no way i ever get 7 hours. im not upset because it still outlasts all my friends laptops. My curiosity is that ive been web browsing for about 30 mins now, also iTunes is open but not running, and thats it. I checked my time remaining for the battery and it was 5h30m. 10 mins later it said 3h30m. 5 mins after that it now says 3h59m. What is causing it to jump all around like this? and is there a way to make it more accurate with its estimates?
also. I have calibrated my battery per the directions on apples website, did it about 5 days ago.
i might get the new MBP once it comes out and i wonder what's better when I'm not using my Mac overnight and so on, turning it off or just sleeping it? Apple clearly states in every manual

What's better for the Computer life? What does sleeping mean? It just turns Hard drives and the screen of or does it save the state of the computer on the HD and it almost turns off? The first time i read i say "Oh BS i'll turn it off every time i don't use it, now i want to know the truth
I just got my macbook week ago. i noticed that the menu bar had a slight pink color on the right side. i went on the apply website and read on calibrating the display but it still has pink lines. anyone has the same issue. also does it matter if we calibrate the display or not. and finally, i read on some site that we supposed to calibrate it in the dark, which i did not do. is that the reason i am still seeing pink color.
View 8 Replies View Relatedi am about to have my first mac, a macbook pro. I live in Turkey and Apple prices are really of the roof here. So i ordered it from Amazon to save 1500$ and had it shipped to my friend's house in USA. He will bring it with him when coming here to Turkey. I ordered on 16th of June, delivered on 23th of June and i will be getting it tomorrow. Problem is i heard that it should be calibrated within a week after buying. I suppose this wouldn't be a problem right? I mean it should be a week after booting it i think?second question is about using while calibrating. I know i can use my laptop when it is fully charged and resting on that state for 2 hours but can i use it while it's charging.

i finally got my High Res Glossy MBP after 4 weeks of waiting...Everything works fine...and NO yellow tint issue...The only problem is 1 small dead pixel towards the bottom right of the screen...Will apple do an exchange on CTO machines with only 1 dead pixel?Is it even worth doing the exchange? After reading these forums i see that a lot of other users have been complaining about all types of problems...Yellow tint, wifi problems, over heating...etcshould I consider myself lucky? And just be happy that its only 1 small pixel?
View 24 Replies View RelatedI usually use my 2209WA connected to my Desktop running Windows 7, but sometimes I'll connect it to my MBP. Windows seems to have found a color profile that works very well, which it got from Windows Update, created by Dell, presumably.It might not be good enough for someone who needs 100% accurate color, but it's good enough for me.
I tried two different profiles for this monitor connected to my MBP. The first was one I downloaded from a forum somewhere, and the second was the one Windows is using, copied over. The display looks OK with both, but the color depth isn't nearly as good as it is on Windows. Connected to my MBP, the colors look washed out and flat, while the same colors are much richer when the monitor is connected to my PC. For example, pure blue (#0000FF) looks faded when the monitor is on my MBP, and much deeper when it is on my PC. I tried changing the gamma setting under OS X (manual calibration), but it didn't have much effect. It is set at 2.2 for both 2209 profiles and for my MBP LCD's profile.
How can I make my monitor properly calibrated when it is hooked up to my Mac?
In both cases I am connecting the monitor with DVI (just moving the cable since I'm too cheap to buy a switch), and both OSes have it set at native resolution. The settings on the monitor (color, brightness, contrast, etc) do not change when I switch computers.
i just had service battery on my laptop and took it to apple. they replaced the battery and explained that if i leave it charging at 100 it overcharges and causes service battery and other errors. is there any programs or something i can use to make my mac stop charging at 99%? or do i just have to manually pull out the charger?
View 6 Replies View RelatedI recently purchased a HP 2009m glossy 20" monitor. I have a late 2008 model macbook pro (glossy). I have been having a hard time getting the colors and whites to look exactly the same. I have tried calibrating the display over and over but the whites never look exactly the same even though the default white points are the same for both the macbook pro/hp displays. Any hints outside of getting a sensor/external program?
View 1 Replies View Relatedi have recently spent several evenings re-calibrating my Dell U2711 display and have finally come up with a fantastic image so I thought I'd share my results for those having trouble calibrating this display (given the low quality AG coating this display comes with, calibration can be quite tough). Plus, during my Google search, trying to find some calibration tips, I was surprised at how little I found. Most of the forums I went to are discussions about the AG coating with hardly any talk about calibration. So, because of that, I figured I should share my calibration steps.
I edit video so I managed to come up with a calibration that shows great shadow detail (without crushing the blacks) yet still gives a deep, rich look for the graphics as well. Everything from the highs to the lows look great! And parts of the screen such as the dock look so vivid it's hard to distinguish from an Apple Display in terms of richness and clarity (without the shine, of course). You can still see the grain of the AG coating on bright areas of the screen but it's hardly distracting at all. On a side note: this is a great display for editing video even with the AG coating but if you edit still photography I would stay away from the U2711 entirely: still image + still grain = disaster!
Unfortunately I don't know much about internal computer system settings or if all displays that Dell ships are identical, so I can't say for sure that the calibration I did will work for everyone. However, if all Dell Displays and Apple computers (I use a 2010 MacPro) are 100% identical when shipped, then, if you follow my steps exactly, you should be able to come up with something similar to what I got. But I can't say for sure:
Step 1: Setting up the display.
Set the contrast to 100% and the brightness to 80%. Set the Gamma to (Mac), the Mode Selection to (Graphics), and the Preset Mode to (Custom Color). Now, in custom color leave the green at 100% and set both the Red and Blue to 98%.
Step 2: Setting up the Mac.
Run your Mac's Display Calibration Assistant (located in the Display section of System Preferences). Select the checkbox for Expert Mode and keep clicking continue till you get to the section with the lined boxes with the Apple logo in the middle.
Now, for all 5 'lined box' steps, make the Apple logo disappear using only the left slider (do not touch the right slider at all). To make the Apple logo disappear (blend into the box) you must squint your eyes until the lines that make up the box itself become one solid color (my eyes were about 75% closed). Take your time and make sure you are confident that the Logo is gone.
Then, when you come to the gamma screen either select 2.2 or 2.15 - the proper setting should be 2.2, however, I found the blacks to be not as deep as I'd like them to be (most likely because of the AG coating) so I choose 2.15 which I found to be the key to giving the display the richness it needs to look great.
When you get to the 'Target White Point' screen, select the checkbox 'use native white point'.
Then save you calibration profile and exit the assistant. Now go back to your Dell display settings and set the brightness to 100% and you should be good to go! Note: if you find your screen to be a little too dark, re-calibrate but try selecting 70% or 60% for the brightness during step one. That way, when you raise the brightness to 100% at the end, it should be somewhat brighter.
I hope this works as great for you as it did me! And even if it doesn't, hopefully you will end up with something half decent. But either way, please do share your results - I know there are a lot of people out there struggling with this display because of it's AG coating and some are even attempting to remove the AG coating with bad results. I even considered removing mine but now I am glad I didn't take the risk (I suck at doing those type of mods, haha). Now, my display looks almost as good as an Apple display (and without any glare!
I recently got the Dell U2410 and I felt like out of the box the color and everything was way off, and certainly no where near matching how things looked on my MBP screen. I went through the little calibration process in the system preferences (with the advanced options) and it's somewhat better (I don't think the gamma was at 2.2 before), but it still doesn't seem so great. The brights look kind of blown out, the shadows are a bit too black, and some of the colors look off. Also, if I look at a solid color I can see moving lines (almost like a much more mild version of when you record a computer screen with a camera running at a different refresh rate).
Did I get a crappy one, or do I need to do something different? I had heard so many good things about this monitor and now I'm considering returning it for a 24" ACD.
My machine: 17" 2.33ghz mbp.After installing Snow Leopard, when trying to calibrate the screen it gets to the end and then reverts back to the ****** default snow leopard calibration and says: "An error occured.

It should be "occurred" no?any of you guys have this issue? and if so, how do we fix it?

I have just completed rescuing a water damaged MB C2D which was originally a 2.16 and is now a 1.83. Fun project for a cold Sunday afternoon. 5 hrs I have one issue with the MB and that is the charging of the battery. The battery icon sometimes shows 'no battery' or if it shows a battery is recognized, it isn't charging. The LED on the mag-safe charger is always green. The battery is from the water damaged 2.16 and my thinking is that it may have suffered damage from being exposed to water. Original owner left the MB in the backyard and it started to rain!
View 2 Replies View RelatedMy battery needed replacing for a couple of months before i dropped it from about knee level onto a sidewalk. After the drop I got the not charging icon. I thought maybe the battery had just finally died. so I did not panic about the no charge. The laptop works fine when plugged in to power with the old battery on or no battery at all. Not at all when unplugged.
When I put the brand new battery on the lap top, the computer shuts down halfway through boot up. I tried holding the power button down through boot up reset, as well as removing all power (plug and battery) and holding down the power button for 10 seconds reset.
I calibrated my battery for the first time since Dec. When I plugged it in this morning, it took 3 hours to charge all the way, and now it's stuck on 99% full, 0:00 till completely charged, and I'm getting an error when I click on the battery in the menu bar that says "Service Battery". When I click on the error, it tells me that it may not be functioning properly and to take it to an authorized apple service retailer. Before I waste 2 hours by going to the Apple store and back, has anyone else had this problem, and is there a way to fix it without having it looked at?
View 4 Replies View RelatedI get the whole part about that I set my laptop to go to sleep in 5 minutes, and if I close the lid it'll go to sleep, and the little light at the bottom starts to pulse, etc. But in sleep mode, my battery seems to drain extremely fast!
For my old Gateway M275 laptop while in sleep mode, it would probably lose about 5-7% of it's battery in a day's duration. With my MacBook Air, I just came back to it tonight after a day's worth of sleeping, and my battery was down to 16% from 29%. And to check, it was indeed sleeping!
If you look at apple's battery life page it states the MBA battery is removable, I thought it wasn't supposed to be?Battery Lifespan For Apple notebooks with removable batteries ? such as the MacBook, MacBook Air, and 15-inch MacBook Pro ? a properly maintained battery is designed to retain up to 80% of its original capacity at 300 full charge and discharge cycles. You may choose to replace your battery when it no longer holds sufficient charge to meet your needs.
View 1 Replies View RelatedI have an early 2008 non-unibody MacBook Pro. For about a year now, the status of the battery has been "replace soon." I was still getting a pretty good amount of time off of one charge so I wasn't too worried. This past Saturday morning, I woke up, checked the battery indicator lights on my computer (it had been sleeping since the day before) and it said it had about 60% percent so I opened it. I was on the Internet for about 10 minutes before it shut off without warning.
It wouldn't turn back on when I pressed the power button, so I plugged it in and it turned back on. When I checked, the battery status was "replace now." After using it, I turned it back off and left for NYC for the weekend and didn't bring it with me. When I got home last night, I plugged it in and tried turning it on with no luck. The battery indicator light was flashing one light, so I just assumed it would need to charge for a bit before it would turn back on. After about two hours, when I went to bed, it still was flashing just one light. I kept it plugged in over night, and this morning when I checked it, the battery indicator lights showed that it was fully charged, but it still wouldn't turn on. I still kept it plugged in throughout the day just in case, but it still won't turn on even though all the lights are lit. Is the battery just showing me false information, or should I be worried about more than just the battery?

purchased a macbook Unibody back in October 2008 when they were released and use it heavily. The battery no longer holds a nice long charge - I get about 2 to 2.5 hours out of a full charge.
The battery has 149 cycles on it, which is obviously high (and correct, I use the hell out of it). With it still being in warranty, is it worth pursuing a replacement battery? Will Apple tell me to go take a hike with the high cycle counts?
