I've noticed a considerable decrease in battery life of my 2008 Macbook white after the 2009.001 security update. Earlier I used to get around 4 - 4.5 hours on normal usage, but its down by about an hour now. Its only around 9 months old, and the battery cycles is just 20.
I check my battery count almost every day, what I have noticed is that the full charge capacity decreases by around 5 every day. Three days ago it was at 5182, and now it's at 5169. I run my laptop on external power most of the time. Is such steady decrease normal?
I'm new to OS X, got my MacBook the other day, and I can hands down say it's my favorite OS I've dealt with. It's so much simpler and just plain awesome. Okay, I'll ask my question before I get carried away...
So, I did some searching on Google after I noticed that my battery likes to hang around 99%. Apparently this is common. My question is, is this a BAD thing? When I see 99% I'm picturing that the computer is constantly pushing power into the battery so it can reach 100%. I mean, isn't that how fires start?
Simply put, is my MacBook trying to charge the battery consistently when it is not at 100%?
every time I'm running my uMBP from battery, I'm constantly checking the amount of time I have left and trying to figure ways to increase that time. Yes, CONSTANTLY. Whenever I can, I'm using the a/c adapter.
Even though I may see 6-7 hours left, I'm still not satisfied.
And just about every time I am running the battery, I'll open up Coconut Battery to make sure I still have a 100% charge hold left....even though my umbp is 7 weeks old with only 4 cycles...
I'm not even coming close to this with my 2010 macbook pro 13 inch unless I turn my brightness down to 50%, on reboot it defaults to 100%. This is when doing nothing or just surfing the net. I can get about 7 hrs, with my laptop screen turned to 50%. Any tweaks available? I'd love to know how Apple came up with 10 hrs.
i have a PowerBook G4 15' Aluminum edition, it gets about 1 1/2 to 2 hours on power saving mode sometimes way less depending if it stays on during the whole class. I was wondering if this was normal or if a new battery would give me longer life?
I have a Macbook Pro I bought in summer 2007, and I'm have concerns about its battery life, and so I was wondering if anyone could help me please.
I hardly ever use my laptop away from my desk, so it's plugged in all the time. While plugged in, I still keep the battery in the laptop. It's only been through 10 cycles in 2 years, and I know I should've calibrated it monthly, but I didn't and I really wish I had now. Right now, when unplugged, my battery only lasts about half an hour. I downloaded coconutBattery and apparently, my original battery capacity was 5600 mAh, and now it's only 543 mAh.
My question is, did I mess up the battery myself by not calibrating it, or was the battery defective in the first place? :S Or is it just old?
I'm a real n00b when it comes to computers....but if this ISN'T my fault, the laptop is under an Apple Care Protection Plan, and so would that cover the battery? Is there any way to fix it without getting a new battery?
As a new 13" Macbook Pro owner, I am wondering if upgrading with non-Apple certified HDD and RAM components could drastically effect the battery life.
I am told that there is firmware in the HDD of the one that comes with a Macbook that is necessary for maximum battery life. From comparing two HDD's in my Macbook (one certified and one not) I think this might be the case. What is your experience?
Also, does there exist Apple certified RAM and, if so, does it offer more battery life compared to non-certified?
I just picked up a new 13" MacBook Pro today and I was wondering what the best settings were for maximum battery life without turning the brightness down too low. This is my first mac so if you could sort of guide me through the process of changing the settings.
I have just bought my Unibody Macbook. I haven't received it yet, but I was wondering if anyone has any tips on undervolting, buying a different battery, etc. to get more battery life on it. I really need it for school and I don't always like sitting next to the plug in a classroom.
I have recently purchased the unibody 15.4", and I can't get more then 2 hours of battery life while web surfing on wireless with Screen brightness at half and backlighting turned off. I am running the 9400m also.
I have the 15" Macbook Pro 2.66 with the 512mb graphics and I was wondering if there are programs out there that I can adjust the battery options more? All I can really do is go from Performance to Better Battery Life (I assume it disables the graphics?). also any must have apps would be great for my new macbook pro. (I have xupport already)
what the battery life of the new(er) unibody macbook pro 17 was like under windows. I read a review somewhere that says the new macbook pro (the one with advertised 8hours battery life) managed about 1 1/2 hours in windows, is this true? the only reason I'm looking at the 17inch pro is because I program a lot in Windows and Linux, and 17inchs would be fantastic to display more code, but I still need good battery life. portability is no issue, as I'm a big guy and I carry 2 computers with me right now anyway. any other cons to installing windows on this beast?
After seeing how awesome the Education discount is, I've decided I will definitely go after a MacBook Pro 17 if I can get this shoddy Acer returned. What attracts me is the thinness, design, keyboard, screen, weight and basically everything except the price. Everything about it screams quality, even the notorious glossy screen which I kinda like.
I have some questions about the MacBook Pros and Mac OSX in general.
1. Is the 8 Hour Battery Life for real? I know that this is some "revolutionary" new thing, but honestly I can't believe something with a WUXGA screen could go for so long.
2. Does Aluminum scratch easily? How about fingerprints?
3. (Applies to all MacBook Pros) Does the hinge of the lid creak or wobble when opening or closing the laptop?
4. Is Leopard 32 bit or 64 bit? Or is it default 64 bit? I can't see any mention of that in the configuration page.
5. How about driver support? I have a Razer Copperhead, Piranha and am ordering a Mamba and it would be a shame if they were not compatible with the OS.
6. Does Parallels or VMWare lag at all when running XP? Or is it the same experience, with no slow down? How about Boot Camp?
I have a 1 yr old Macbook Unibody (13.3"- Late 2008 model).
I have the 2.4Ghz version.
Anyway, here's what I have:
Original Batt Capacity = 4100mAh. Current = 3953mAh (can dip to 3800 at times) Battery Load cycles = 58
I'm currently running on batteries. I only have my browser opened along with some widgets and WIFI. I've taken all energy saving steps as well (lowest possible brightness on screen and keys) Currently sitting on 86% w/ 3 hours left..............
I know that keeping a battery on charge after it is fully charged can decrease its battery life by 30%, but I also know that Apple's batteries automatically stop charging when they have reached 100%, wait till the battery drops to 97%, and then start charging again. I need to know if the battery life will degrade if I keep the laptop on charge...
Are there any Windows 7-native notebooks with a "clean" design (where "clean" is MBP-ish), a battery capable of seven or so hours like the MBP's is, and a weight close to the MBP's 5.5 lbs? Seems the closest thing as of now is the Envy 15, but from what I understand, the slice battery is required to get the battery life beyond a few hours -- and using it bumps the notebook's travel weight to ~7.8 lbs.
I was having bad battery life (under 2 hours) And noticed my fans were not spinning up to counter the increase in heat.
I called Apple and they had me reset my PRAM. With that done the system worked fine for a day.
Currently my Unibody will not stay connected to any wireless networks. I have tried 2 of my own routers and a friends. It will not stya connected, either on AC or battery.
Next issue involves CPU hitting 95c before the fan go past 2k rpm. Try and and play wow and the system locks up when the CPU hits 98c and the fans are still at 2k. Tried reseting the PRAM again, no luck.
Recently my brand new studio 17 updated, about a week later I noticed that 50GB had gone missing! I of course called tech support to see if they could help (good luck) after spending hours on the phone they could not really solve the issue, asides from doing a factory reset.
Now again I am having this issue again, once Vista updated it is slowly eating away hard drive space. There is currently 31.4GB being used (yes, this includes all hidden files) on a 450GB hard drive, yet the system reports only 402 GB free space. Each day it decreases about 2-4 GBs ......
1.I really didn't find much info on the (now not so) new white unibody Macbooks, expect some items for sale. And please, don't tell me that just buy the aluminum model for the extra $200, my question is strictly from an engineering point of view: heat. We all know aluminum Macbooks are quite hot, right? But how does the white unibody compares to the aluminum regarding heat issues?
2.What might be the reason that the whole bottom of the white unibody contcts the table beneath it, compared to the aluminum model, which has four rubber contact points on the four corners?
3.On the other thread I read a dedicated graphics card does not really add to battery consumption. Can you confirm that?
My main usage profile is office, web and seeing (HD, if available) Youtube videos. This one is rather a 15" vs. 13" Pro question, and half hypothetic. Let's say, all things are being equal on two models, the processor none the least, the only differences are one model has the integrated Nvidia, the other the integrated Intel plus discreet Nvidia combo, which one would serve me better, regarding performance and battery life? The discreet graphics would at least turn on when playing the HD videos?
4.Running native Windows (7 or XP) still suck on Macbooks, because of the drivers?
my UMBP got way too damn hot. and was getting tired of the heat. So I started out just taking the bottom of the notebook case off and blowing it out. Then I started looking at it more closely, the fans have no direct access to fresh air intake. Yes I know the speakers/keyboard are meant for that. But the tinkerer in me fired up the drill press and with a 11/32 bit started making some small holes areound the fan intake and ram. Well my MBP now runs so much cooler before I was running 44-55C on mbp just idling and light web browsing. No I am so so happy to say my MBP is running at 35-40C. That is significant decrease in temps.
