How much sound does a RMBP make
I'm planning on getting my first Mac. The $2,799 MacBook Pro with retina display 15". I have a student discount so it will be $2,599 instead.
I am going to wait for the next generation of MacBooks to be released, also I have a question about its sounds. Will it make a lot of sound like fan noises? It needs to be COMPLETELY silent. Because I will be using this next year in class when I'm a sophomore. And does the keyboard make any noise either? Thanks!
Also, if I get something like "it depends on what you are doing" here are some examples.
5-7 tabs open and a text editor for notes, some system settings and misc things. No gaming. How much sound does this make?
Thanks in advance!
I have one and it is totally silent, unless I am mirroring video to my tv, then the fans kick on.
For example, I routinely have ten or more tabs open and it is silent. Video or video editing may make the fans be audible. The keyboard is quiet.
I am a low income person who loves the retina display. It makes ordinary photos seem professional. The extra size from the 13" is useful.
Best to play with the choices at an Apple Store to check out your preferences, if possible.
Text on the retina kind of spoils me for any other computer.

How much space does tiger take up & how to make it take up less
i recently read a post by someone claiming that tiger took 18.5gb on there ibook, and some one replied saying that apple claims you can install tiger in to 3gb.
: is this true?
: if so, how do you "compress" it?
: iff not so, how much space does it take up on avarage?hi Axl....
I've got tiger in ok, running fine - bought family pack and have done 3 installs without problem, so that's the good news ....
I did a major reshuffle and toss-out of files before I installed - bought 80gb mobile external hard drive - and did install with 5+gb free, so after it had about 3gb free, then all of a sudden I went down to less than 1gb
I've been in a hunt for more files to throw out (a nice find were the old ipod updaters that were eating 500mb) ....
If I want to throw out most of the language files (for instance) ... where are they ? (I did search for danois and found nothing, so .... buried ?)
any other suggestions for things to throw away .... I've pretty much eliminated 90% of all things classic, for instance ....
and - do you have ideas for why space seems to disappear so fast .... I'm not doing anything special, but wham, 2gb flies away to ???
thanks -
How much storage does the iPod Touch start with?
I no this may sound like a stupid question but I no from preivous experience that when you buy an iPod you don't the full storage they say you get. e.g. my current iPod (Classic 80GB) only comes 74.2GB of storaage.
*So my question is - how much storage does each iPod Touch model start out with?*
For example, the 8GB model may only have 7GB to start out with.
thanks in advance.
Message was edited by: alangeorgeYou will find ALL storage devices act this way. Your computers hard drive is the same (actual storage of a gigabyte sized drive will be 0.93 times what the stated size is).
An 8GB touch will be about 7.4GB.

That question has a lot of variables. If you are just looking up an address it should not using very much. If you are using it for an 8 hour drive it will use quite a bit.

How much electricity does an Airport Express use (approximately)?
How much electricity does an Airport Express 802.11n use (approximately)?
Is turning it off at night to save money a good idea or a bad idea?That's exactly the data I needed to know. Thank you very much!
I was concerned because the Express is always quite warm, which sometimes can mean big energy bills.......

I've just measured it using a digital wattmeter, and it draws 4 watts when idle. This means about 3 kWh/month, or 0.60 €/month (at my current 0.20 € / kWh), so it is not the culprit of my huge energy bill...
Surely it is not worth the hassle of unplugging it everyday, with the accelerated ageing it causes to the device. -
How much space does a new app take?
My 16GB Touch is pretty full (about 360MB left after all the music is loaded). How much space does the typical app take up?
There are some that are larger (Super Monkey Ball supposedly takes up 36 MB), but most that I have seen or downloaded are around 1 MB. SUPER small

How much energy does a "brick" power cord take?
Hi,
1. How much energy does the White Brick power cord consume when the computer is fully charged?
A. Does it vary based on processor action?
B. How bout when the computer is sleeping?
C. How bout when the computer is off?
2. How much energy does it consume when it's not attached to the computer?
A. I also want to know this for chargers for other Apple devices.
Thanks for any info on this. I haven't done any searching on this, so maybe it's an obvious question.Thanks for these answers. I neglected this post for a while as I didn't have time to investigate. The answers were helpful.
I did find some more information:
https://discussions.apple.com/message/6423752#6423752 lists (for a 2008 macbook) the consumption. I would be interested in seeing this for the latest models. Especially interesting is this: "Power brick energized, but not attached to computer - unmeasurable." Is the power adpater (it's a transformer) this energy efficient? This is a big deal if I am planning on unplugging my laptop at night.
I also see this: https://www.apple.com/macbook-pro/environment/ . But, unfortunately (and outrageously), it does not give details (it is not outrageous as a status quo piece of marketing, but it's outrageous that the status quo is that little information! So, the problem is not Apple, per se, but the habits. Maybe that is an area for a marketing company to improve on!
I found this for some more, general information: http://electronics.howstuffworks.com/everyday-tech/plug-in-transformer.htm . That gives: "The power consumption is not large [on power chargers] -- on the order of 1 to 5 watts per transformer."
I'd certainly be interested in information on Apple's other products (like iPod and iPhone chargers). -

How much time does a single transmission take?
Hello,
I was wondering what is the time taken to transmit one sample takes. For example, if the sample interval is 5 seconds, does the actual transmission take 10ms? What does it do for the rest of the time?
Also, how much energy does a 3202 node take to transmit a single sample?
Thanks,
SravanHey Sravan,
I wanted to provide some additional details to Kyle's post above.
This is on average what we have seen with a 3212 node sampling at a 60 second sample interval:
Sleep Duration: 58.774 seconds
Sleep Power: 7.41 mJ
Acquisition Duration (All 4 channels): 1150 ms
Acquisition Energy: 2.84 mJ
Transmit Duration: 55 ms
Transmit Energy: 9.17 mJ
Receive Duration: 21 ms
Receive Energy: 1.83 mJ
Additionally, if your sample rate is above 61 seconds, then you will run into the Heartbeat Interval which fires after every 61 seconds of inactivity. Below are average power measurements for the heartbeat interval:
Transmit Heartbeat Duration: 55ms
Transmit Heartbeat Energy: 7.79 mJ
Note: Each heartbeat will then also need to account for receiving that a response from the gateway (Receive information from above).
Taking all that into account, the graph below shows estimated battery life for sample intervals up to 300 seconds. The dips in the graph represent a sample interval that is just larger than the heartbeat interval, which essentially means you are transmitting twice in a very short period.
Hopefully you find this information helpful. Please let me know if I can clarify anything for you.

How much ATI does a macbook have?
My child wants to get Team Fortress 2 but i heard it didn't work on his friends computer. How much ATI does a macbook have?
Acually I'm sort of right since AMD dropped the ATI name in Aug. 2010. http://en.wikipedia.org/wiki/Radeon And Apple didn't use them in MacBook Pros until 2011 http://support.apple.com/specs/#macbookpro
Current MacBooks use the NVIDIA GeForce 320M graphics processor with 256MB of DDR3 SDRAM shared with main memory. They've used the Nvida since early 2009 http://support.apple.com/specs/#macbook -

Installation of Windows 7 is required at least around 20GB of disk space 64bit version, 32bit version is around 16GB, 100GB is a sensible amount of disk space for a Windows installation, I suppose.
