My MBP 15" Hi-Res Glossy i7 is on the way (ordered on 19th) and I was just wondering how the batteries on these machines were doing. I've seen a lot of feedbacks from great (8~9 hrs) to average (4~6 hrs) to bad (2~3 hrs). So how is it that these reports are varying so much? Is it possible for numerous defects to be out in the world right now?
View 6 RepliesMy battery for my 12" Powerbook G4 is munted and i need a new one. There are a few around for about $90AUD from 3rd party re-sellers which is less than half the $200AUD apple want for a genuine battery.
So i'm just wondering, has anyone got any recommendations about 3rd party batteries? i know it will probably vary a bit depending on where they're from, but i spose i'm just wondering if its worth the extra $100?
Battery
I had a 11 inch air 1.4GHz/4GB/128GB for two weeks. I usually set the brightness to 75% and for consistent web browsing (no heavy flash) I can get about 5h15min battery life. I noticed someone here claiming 8+ hours battery on 13 inch so I decided to give it a shot.
I got a new 13 air with 1.86GHz/4GB/128GB yesterday and start to run on battery immediately. I was disappointed. The brightness was also set to 75% and I start to count the time from 25% while browsing MacRumors.com. And it only took 1h38m for battery descending from 25% to 0%. Again, pure web browsing and no heavy flash.
So here is my conclusion: On 75% brightness, 11 inch air's battery performs beyond advertised 5 hours and 13 inch's battery performs fair and normally should give you around 6h30m~7h.
Noise
I don't have equipments for measuring the noise, but while copying the same 10GB files from external drive to the machine, the fan noise from 13 inch is much louder than 11 inch.
Now I like my 11 inch more in general, although I really hate the 1366 x 768 screen. I don't know if I should sell the 13 inch or 11inch...
[edit]:
On my 11 inch air: battery capacity 4664
On my 13 inch air: battery capacity 6634
[edit2]:
I will do another test to see how long exactly my 13 inch can last after a full charge
To those contemplating on picking up the 11-inch MacBook Air or the 13-inch MacBook Air, I thought it would be helpful to list the differences between the two.
Below is what I've compiled so far (in no particular order):
1) SD Card Slot is on the 13" MacBook Air, not present on the 11"
2) Higher clock speed configurations on the 13" (1.4 GHz/1.6 GHz vs. 1.86 GHz/2.13 GHz)
3) 6MB of shared L2 Cache on the 13" vs. the 3MB on the 11"
4) 1066 MHz frontside bus on the 13" vs. the 800 MHz on the 11"
5) Larger capacity battery and an extra 2 hours of battery life on the 13" (7 hour 50-watt-hour battery on the 13" vs. 5 hour 35-watt-hour battery on the 11")
6) Slightly larger trackpad and more room for your palms while typing (hey, it's true!)
7) 16:10 1440 x 900 13.3" Display vs. 16:9 1366 x 768 11.6" Display
8) The 13" model weighs in at 2.9 pounds while the 11" weighs in at 2.3 pounds. .5 pound weight difference
If you have anymore differences between the two models, post below and I will add them to the list!
I am trying to use my HD Sansui 32 inch LCD TV as a monitor for my Macbook. I can't work out how to set it up properly. My macbook is running OS X 10.5.8. My TV supports 1920 * 1080 HDMI 60Htz NTSC and various other resolutions. I am using a mini DVI to DVI adapter and then a HDMI lead to the tv. Problem one is that when I switch the Macbook on and close the lid nothing comes up on the TV screen (meaning it is supposed to only driving one screen, the TV). If I do this with the VGA connection it will. Momentarily the apple symbol will come up and the little circle below it but then my TV says signal not supported.
If I have the Macbook lid open when I switch the computer on both screens will work and I can select 1080P, however it is very grainy and not pleasant to read text. I think it looks better using the VGA. I have heard of people getting nice crisp display with HDMI so I am wondering if I am missing something? Is there any other software that can be used to get better results? Which text smoothing settings should I use? Are there other settings? I am using it on my desk so I guess it is about 2 foot from me. I will post my display details in a minute but my computer details are the following:
2.2 GHz Intel Core 2 Duo
1 GB 667 MHz DDR2 SdRam
I'm getting one for school and i'm going to have to carrying it aroound quite a bit, so the 11-inch seemed appeling at first, but then i noticed that there is a few pros to the 13-inch than the 11 inch: There's an SD card slot on the 13 inch, which i could care less about, the screen has higher resoulotion, which i don't really care about eiether, but the one difference was that the 13 inch has two hours more battery life, which kinda got me thinking towards the 13-inch. So what do you guys think, is it impossible to work on the 11.6 inch and should i go for the 13 inch, or should i go with the ultra-portability of the 11-inch?

I brought the Mac at the Apple Genius. They say there has been a liquid leak and asked me $780.00 for the repair (it does not make sense to pay this amount for this computer). I am not aware of any liquid leak. Yes, I had my MacBook in my backpack during rainy days but I had an umbrella. Anyway, I would like to have any advice about (i) where I could bring my Mac to repair (I live in the Bay Area) or (ii) what I could try to replace, following tutorials (like the very good ones on ifixit site).
I have an early 2011 Macbook Pro 13 it was working OK but now has come up no batteries detected and I have tried a pram reset, smc reset and a new battery but still no luck. I did manage to get it to work for a while by turning it on with the power adapter connect then restarting it but at the point of the restart I pulled the power and it came on with the battery.
If I start it with the power adapter connected and then pull the power it will boot to the login screen briefly then go into sleep until I reconnect the power. When the power adapter is connected it just has a solid green light at all times never changes even if I do the smc reset.

My macbook is a week and a day old. It is the newer whitebook with nvidia and all that. Coconut battery says its 123 months old? why is this? The only thing i can think of is that apple possibly had a used macbook come in and they switched out some parts and changed it to the new one? btw it was bought new at best buy.
View 5 Replies View RelatedI think built in batteries are a good idea , but having to give your computer to apple and pay 200.00 after your battery dies is not.
how have your built in battery experiences been?
do they last long as stated 7 hours?
not sure if i want to make the switch , i like my removable battery.
I've got the dreaded "No batteries available" at the top of my taskbar. The Power Source says: Battery. I have my laptop plugged & it is showing a green light. What is a simple way that I can fix this problem? I can't go to a Genius Bar because the closest Apple Store is over 120 miles away. The battery is a little over 2 years old

Why has Apple not recalled the batteries in the white macbooks(early 2009) when it is very evident that these batteries have a manufacturing fault? Mine has swollen after 112 recharges but should have lasted 300 recharges before only having 80% capacity after which it will still work, just not as many hours. Because of the excessive cost of Apple batteries and Apple's releuctance to recall defective products my next laptop will be a windows8 machine.

View 3 Replies View RelatedHello everyone, I'm currently looking to buy a 27 inch imac and can't decide whether to get a base i3 27 inch or a refurbished i5 quad core 27 inch. With the i3 I can get the student discount and qualify for the ipod, but the i5 is 23% off right now. Which should I get? Also is there a benefit of getting a 5 series graphics card over a 4 series graphics card?
View 4 Replies View RelatedI have a Late 2006 MBP (This one).
I don't use it much (it's for travelling).
I leave it plugged into the wall or unplugged for weeks at a time without using the battery. Since I bought it, I have gone through 4 batteries, including the one that came with the machine. That's over $500 in batteries!
The computer says "Batteries not Charging" with an X in front of the battery icon. Or it says "No batteries available".
I'm about to buy my 5th battery. What should I do this time to prevent it from dying like the others? Or is it a problem with my computer, and not the battery?
Can anyone assist me in find the promotional video that Apple did when it went to non-removable batteries? I would like to find it in a high quality format. I need it for a school presentation. I've found it on YouTube, but the quality is not that great.
View 2 Replies View Relatedi'm sure there are many people who use spare batteries like me. but how do you manage them though? i find it very annoying having to charge them one by one. charging 1 battery takes a few hours, which is almost fine. but when you have a spare battery, it takes twice as much longer to charge them both. not fun. a separate battery charger will help greatly reducing charging time
View 18 Replies View RelatedAs you can see from the info at the bottom of the post, I own the 2008 model. Now, with my hardware slowly becoming obsolete and the wear starting to show its effects, I would have to get a new laptop in the near future. However, as I discovered, all new models have batteries that cannot be removed. After 2 years of service my battery swelled and had to be replaced. That's 2 years. With a new battery, my laptop's life has been prolonged.
How long will a new laptop last? Will I really have to buy a brand new expensive computer every two years just because of a design flaw?

I recently changed the batteries on my wireless Apple Keyboard. When I turned the Mac back on the keyboard wouldn't connect. Confused, I went in to system preferences where I got this message. I've searched for the problem in Apple Support on their website but to no avail. I have Applecare. Is this something I need to take up with them? Should I take my Mac to a genius bar?

I got a MacBook Pro back in April, my first Mac.
I love it so much. I'm really into video editing and HD video, but the problem is that my MBP is running out of harddrive space, and I'm longing for a bigger display and a better processor. (I have the 13" C2D). I'm going to pick up an iMac this Spring. But I wanted to know if I should stick to the Core i3 21.5, or spend more and go for the 27 inch.

I need more rechargeable batteries as I've used up all the ones that come with the Apple charger. Since Apple doesn't sell them separate I'm just wondering if I go get some Sanyo batteries will they work for sure with my Apple charger since they are similar or is there a chip in them to stop them working with 3rd party batteries like on a notebook battery?

I think the original power adapter was bad and ruined the original DC board and the new one. I'm going to try one more DC board and if it doesn't work then give up the parts on eBay. Problem is, I need the data off the hard drive. Is there anyone in the Kansas City area who has an iBook 14" 1.42 GHz and would would be willing to charge the batteries for me? I wonder if the Apple Store might do this? This way, I can turn on the iBook and copy the data to another machine.
