MacBook Pro :: Difference In Battery Time 45 And 60 Watts

Sep 12, 2009

I'm in to buy a second hand Macbook unibody - the one that didn't exist for very long, until it was slightly upgraded and rebranded as Macbook Pro. 13,3".

Differences I've found so far add up to these:
45 watt changeable vs 60 watt built-in battery
2.0 Mhz vs 2.26 Mhz
- vs Firewire 800 and SD card slot

One question would be - how much does the battery time differ between 45 and 60 watt?

Then I heard that the screen might have been updated too, something that for me makes more value than all the above. A quote comparing the white Macbook ("WhiteBook") with the unibody Macbook pro: "While both machines have 13.3-inch glossy displays, the unibody has also been upgraded to a higher-quality screen from AU Optronics with 60 percent greater color gamut, another advantage over the WhiteBook."

Does the unibody Macbook have the same screen as the white macbook, or does it have the same as the unibody Macbook pro - or something in-between? Does someone know of a comparison between the two?

I'll do a lot of graphics - picture editing - so it's important for me.

OS X :: Difference In Analog And Digital Clock Time Display

Apr 2, 2009

I just bought a new MacBook Pro 15" running Leopard 10.5.6, and the clock is being weird. Last weekend we put the clocks forward an hour here in the UK and I suspect this has something to do with it. What's happening is that my clock is displaying an hour earlier than it actually is, and if I put it into manual mode rather than relying on the Euro Apple timeserver, that fixes it but then the time on my Mail is wrong - it says each message was received a hour before it actually was.

Then it gets really odd - if I change the timezone to London BST and then check the time & date panel, the digital clock still reads an hour early, but the analogue one beneath it displays the right time Then if I close the panel and re-open, I find it's reverted to GMT and both clocks say it's an hour early.

OS X :: Apple Time Capsule - Difference Between Older And New Versions

Jan 24, 2010

I basically know someone that is selling the 500GB Time Capsule which has Dual Band Wi-Fi etc, this is the link for it on the Apple refurb website
http://store.apple.com/uk/product/FB764B/A
All I want to know is, apart from the obvious 1 or 2TB of space available in the new versions is there any other differences? Both are 802.11n and are dual band. What I have noticed thought is that there are refinements which allow it to be backed up 75% faster than the previous generation and it says there is a 50% better performance over Wifi with 25% greater range?

How is this possible if they are both 802.11n? Also Is this true even when connecting via Ethernet? In terms of when I backup over Ethernet will it be 75% more faster? It'll be on my desk so I don't really care about the wireless capabilities. Lastly, will it work with my network, please click on this link as it explains my setup.
http://forums.macrumors.com/showthread.php?t=853136
So just to reiterate, will I notice a difference in back up speeds when connected via Ethernet between the two versions. I'm getting it quite cheap, for about $50 Brand New sealed.

Hardware :: Time Capsule - Direct / Wireless Internet - Difference?

Nov 19, 2009

Does it make a difference in speed if I have the time capsule connected directly to the internet, opposed to it connecting wirelessly? I'm still backing up and using the Time Capsule wirelessly from my computer, but I have the internet plugged directly into it- making a wireless network for my laptop to pick up. Does it make a difference? I would kindof imagine that it would only make much difference if I plugged my laptop itself to the Time Capsule directly, since wireless internet speed doesn't seem to different on it's own anyway.

MacBook Air :: Charging The MBA Battery For The First Time?

Nov 24, 2010

What's the best thing to do with the MBA out of the box? Should I use it and drain the battery to zero or not even turn it on and just charge it?

I want to treat it nicely from day one ...

Also, on the same topic of treating it nicely, do you recommend a screen or keyboard protector? I had a keyboard protector on my PowerBook G4 (iskin). While it kept the keyboard nice and clean, I suppose it didn't give me the best experience I could have had with the keyboard itself. I now realize that I can't really read the keys because the protector is so dirty.

MacBook :: Time To Replace Battery

May 17, 2009

I routinely put my Macbook to sleep with a full-charge at night, then unplug it (the power cord doesn't reach where I keep my computer at night). When I wake it up, it generally has 93% of a charge left. This has never happened and I am wondering if it is time to replace the battery.

OS X :: MacBook Pro Battery Time Variation

May 5, 2010

I am totally new to macbook. After being a very supportive Windows user I finally decided to change that and get the Macbook pro 13". I was trying out the battery and wondering there a bit. I charged it fully and when I started running the mac on battery the remaining time showed around 10 hours, then it would start jumping, suddenly it went to 9:30 and further down. The lowest within half an hour use was 4:30 and right now it's up at 8:50 again. I was wondering whether this kind of "jumping" is normal or whether just my macbook is doing that? I am really happy with my decision so far, I love the macbook and I am sure while trying it out in the next week or so I will come up here with some more questions!

MacBook Pro :: Battery Time Keeps Fluctuating

Jun 28, 2010

The battery time on my Macbook Pro 15" goes from one time to another in a matter of minutes. I fully charged the battery after it had been drained. This is what I mean by fluctuating:

11:23am-11:28am (5m)
7h51m, 5h54m, 6h57m, 6h16m, 5h29m, 6h38m, 5h53m, 6h29m, 6h9m, 6h13m

11:29-11:34 (5m)
6h39m, 6h36m, 6h4m, 6h8m, 6h49m, 5h52m, 6h30m, 6h0m, 5h43m, 6h30m

Apple states that it should get 8-9 hours on a full charge and mine gets 6h15m. It's only 10mos old.

MacBook Pro :: 5 Hour Battery Time Is Normal ?

Apr 20, 2010

My new MBP has 5 hours of battery when doing light web browsing at medium brightness. Only 2-3 hours when playing low res youtube clips, and 6:45 hours with all apps and wifi turned off and screen brightness at minimum.

When I first turned on the MBP I charged it to 100% and then discharged it down to 0. Is this battery life normal? What happened to 8-9 hours with wifi and web browsing? I can't even get 7 hours with everything off!

MacBook Air :: Over Heating Eat And Limited Battery Time

Jun 7, 2010

I have a rev B MBA, which is gorgeous but I have found myself using it less than any other Laptop I've ever had and it is simply due to two reasons:

- Heat, pretty much anything except simple browsing raise the heat
- Battery time, simply lousy (including charge time)

Have had it for a while, 14 months, but at this point I have started looking at the 13 and 15 inch versions as replacements down the road. I thought it would make a great compliment to the imac but due to the limitations above I use it less and less. If only they had added a fraction of an inch of thickness to allow better heat handling and more battery.

MacBook Pro :: Battery Time - Getting 2 Hours With Full Charge

Jun 27, 2009

Late 2008 refurb Macbook Pro, 2.53ghz, Windows 7 RC (therefore forced to use the 9600 at all times). According to this report, the MBP got around 3&1/2hrs of run time with a dimmed screen and watching videos. From a full charge, I start browsing the internet (no videos at all), and my battery reading read as follows

91% 1hr, 16mins
90% 1hr, 20mins
89% 1hr, 24mins
87% 1hr, 23mins

Not only were the readings all over the place, but even from a full near charge I wasn't even getting an estimate of 2hrs, while Apple advertised 4 for the late 2008 model, and the review I linked to says they got 3&1/2. Do I have a bad battery, or does simply running the 9600 reduce the battery life by such a drastic amount? I have already calibrated my battery following the guide on the Apple website.

MacBook Pro :: Battery Died While Using Time Machine / Lost GB

Aug 16, 2010

I was doing my first-ever Time Machine back-up tonight. I have about 130GB of data. About a half hour into it, my battery died and when I rebooted the computer from sleep mode, Time Machine said that the back-up had failed. I deleted the initial back-up in the 'Time Machine Back-Ups' folder, but it still says that I have 40GB less on my external hard drive than I actually do. My external hard drive is 300GB, so I should have 170GB left, but I only have 130GB.

Hardware :: Speed Difference Between Time Capsule Backup Versus Hard Drive To Extreme Connected Via Usb?

Mar 16, 2009

For almost the last year I have been using an Airport Extreme on 2.4b/g and and Airport express in my room to extend my wireless network. I also have a usb hdd configured to back up my macbook using time machine. Well I have a new roommate moving in and he has his own extreme and two expresses.

I have some questions on what would be the best way to consolidate our networking devices. I considered us selling our extremes and getting the new time capsule so both of our macs can use 5ghz while my girlfriends dell uses the 2.4.

Is there a noticeable speed difference between time capsule backup vs hard drive to extreme connected via usb?

MacBook Pro :: Battery Time Remaining Indicator Works Wrong ?

Oct 28, 2010

I am new (sort of) to owning a Mac, I bought my macbook pro a couple days ago, so far I havent used it much for other than surfing the net. My question is regarding the Battery time remaining indicator, first of all it changes alot, so i never truly know how much time I have left. Is this normal? It can say anywhere from 3-6 hours left when I am at 90% battery. Usually at 90% battery it says I have about 4.5 - 5 hour left. I thought I was supposed to get up to ten hours of battery? The percent indicator seems to go down fairly fast like 1% every few minutes. Is this Normal? Should I take my macbook over to the apple store to be checked out?
