A Question About MacBook Power Adapters

I found a mid-2007 black Macbook (Merom CPU) at my university's trash with a broken screen.
So, I took it apart and ordered a new screen for it (everything else worked):

But, the trashed Macbook didn't have a battery or AC adapter. I have a Macbook Pro and two 85W adapters. I Googled to see if I could use the 85W Pro adapter as a 60W replacement, and the answer seems to point to yes, so as long as the output level shows both 18.5V–4.6A and 16.5V–3.65A.
But, only my larger, older 85W adapter shows that:

My newer, smaller 85W adapter shows only 1 output instead ((16.5V-18.5V)-3.6A):

So, my question is, can I use the smaller 85W adapter with a Macbook?

A few questions about MacBooks and Parallels Desktop.

I have a few questions about MacBooks and Parallels Desktop.
1) I understand I need at least 1GB of RAM to run Parallels Desktop but what about the hard drive, is the stock 60GB drive big enough?
2) Related to question 1, even if it was big enough to allow me to install and run Windows would the 60GB drive be enough if I wanted to install a Linux distribution as well?
3) This has nothing to do with Parallels Desktop but thought I'd ask it here anyway, do Apple Stores carry just the stock MacBooks, or do they carry other configurations?
Thanks

1. Depend on how intensive you use that HD for saving data on both Mac OS and XP. For standard installation on both OS X and XP, the space of 60 Gb is enough.
2. Same answer as no 1. You can install all three on that HD space, but the extra spacce available will be less and less for your data. You can save your data on external or back up on cd/dvd and erase it from the HD to keep the free space.
Remember to leave at least 2 or 3 Gb for virtual memory usage.
3. Just call them, maybe they don't have it in store stock, but by appointment they might configure one for you before your pick-up date.
Good Luck

Is it ok to use the other macbook power adapters with the mb air?

I have a few extra power adapters for the Macbook Pro and Macbook. Does anyone know what Apple officially says about plugging one of those into the Macbook Air? I've heard rumors that it's risky and might void the warranty, but I would like to see a direct quote if there is one.
I know those other magsafe plugs are impossible to use if you keep the MBAir on a flat surface, but it's definitely convenient to use a spare Macbook Pro / Macbook power adapter if you put your Air on a laptop stand, or even on a book.

I think we are mixing terms here.
I believe the Macbook Air, Macbook and Macbook Pro power adapters are 45W, 60W and 85W respectively. The power adapters don't push power to the notebooks, the notebooks draw power from the power adapters, Consequently you can always use a higher wattage adapter.
The Macbook and Macbook Pro use different voltages but all the power adapters seem to be able to use each. The Macbook Pro uses 4.6A (amps) and the Macbook uses 3.65A and the Macbook Air 3.1A. Pushing to many amps to a device would ruin the unit, but it seems like this has been planned as you can mix and match all the magsafe adapters today and they all function properly.
I have read that the notebook knows whether it can draw enough power to recharge the battery or only enough to run the computer while it is on and that in the latter case it will charge the battery when the notebook turns off. Whether this is bad for the charger or the notebook is unclear, but since the notebooks seem to respond intelligently in those different situations I think that the apple engineers have planned accordingly. If you draw too much power from the airline adapter for example, the airline adapter will simply stop providing power temporarily and the light will go off for a moment.

Macbook Power Adapters

I have a two-year old Macbook Intel Core Duo. It has gone through 4 power adapters.
The first two power adapters had the issue of the cord breaking where it connects to the transformer. The third one simply stopped working, it was getting no power to the computer. I went to an Apple Authorized store to have someone look at it, they said there was nothing they could do. Apple's webpage said that they could evaluate them for replacement if necessary.
http://support.apple.com/kb/TS1414?viewlocale=en_US
After going to the authorized store, I called Apple and was told that they wouldn't do anything about it and I should try to take it back to Best Buy since I had bought it there and "it would be silly to buy an new one if they would replace it." I responded that it was silly they can't make a power adapter that works.
Basically, I was wondering if anyone had experienced similar issues and how to best keep power adapter number four from breaking.

I also have an Intel Macbook that came with a 60W magsafe adapter. The wire that permanently connects to the square adapter brick has severed slightly and now the power cuts in and out. I am always gentle with electrical cords, but i think this happened while it was in my backpack. Now when i use the adapter (have to hold the wire in just the right position) there is often a burning electrical smell - and that just seems wrong - maybe this 60W unit runs too hot anyway. So obviously i must buy a new adapter for 80 bucks, but i was wondering if anyone has repaired this wiring at home. I have looked under the torn insulation and it looks like there's an outside wire wrapped in a shielded pattern around another inside wire. Maybe a repair like this is over my head? Anyone try this before?

Basic questions about macbook pro + external monitor

Hi,
I have some very basic questions about using a Macbook Pro + external display. I don't actually have them but need to know how things works.
So, here they are:
1) Can I use the external display as the main display?
2) Will the external display run with its resolution or with that of the mbook pro?
3) Somewhere I read that you cannot keep the macbook pro open and get the full resolution of the external display. Is that true ?
4) Is it dangerous to keep the mbook closed while using the external display?
5) Does the usage of the external display impact on mbook performance?
I know...a lot of questions , but would be nice if someone could help me.
Thanks.

Hi - I am presently using an external display.
To answer your questions in sequence:
1. Yes you can use the external display as your main display. The way to enable that mode is to put your MacBook Pro to sleep, attach the external display. Wake up your MBPro with the lid closed and you will see the external display as you main display. You can alternatively set the external to "Mirror" your notebook by using preferences/display.
2. The external display will run at its resolution although you can adjust and calibrate it using Preferences/Display.
3. Not true. You get max resolution on both displays. Of course you may have to tweak as mentioned above.
4. Not at all. I use this mode all the time. Just make sure you initially set up as mentioned above and your LCD on the MBPro will stay off.
5. I have not seen any performance degradation whatsoever.
Hope this helps.

Questions about Macbook

I am about to go into my first year of college this July, and I've been looking for a laptop. I've used iMacs before a little bit, but I have a few questions about the Macbook Pro and Mac OS X 10.5. So if someone can help me that would be great.
First of all: How is the Macbook Pro overall as a laptop? Is it a pretty good one?
Secondly: How good is the back-up utility? (Time Machine) Is it pretty good? How big of an external hard drive would I need to back up everything?
Third question: How is the program Boot Camp? I'm planning on putting Windows XP Pro on the Mac using Boot Camp. How is compatibility? Also I've heard that if you make the partition for Windows less than 32 GB, the partitions would be able to "see" each other... does that mean Mac OS X can read FAT 32 drives? Would I be able to transfer files between the two OSs with that setup?
and lastly: Would Mac OS X be able to read my flash drive?
Thanks in advance everyone

I find it phenomenal, the best laptop I've used. OS X is a versatile and stable OS, and the hardware hasn't given me any trouble.
Secondly: How good is the back-up utility? (Time Machine) Is it pretty good? How big of an external hard drive would I need to back up everything?
It works great for me. You can't be nit-picky, so if you want a backup program with lots of settings there are plenty of options, but for those of us who just want something to fall back on when the HD goes kaput or we delete a file on accident, its perfect.
Third question: How is the program Boot Camp? I'm planning on putting Windows XP Pro on the Mac using Boot Camp. How is compatibility? Also I've heard that if you make the partition for Windows less than 32 GB, the partitions would be able to "see" each other... does that mean Mac OS X can read FAT 32 drives? Would I be able to transfer files between the two OSs with that setup?
I haven't used it enough to answer the file sharing questions, but in my limited use it's been excellent, and many friends rave.
It's worth noting that when PC World was testing the fastest Windows Vista laptops, #1 was the MBP running Vista on BootCamp.
and lastly: Would Mac OS X be able to read my flash drive?
Yes. USB drives work great. The only thing, when you delete a file off a flash drive with default formatting, you'll only send it to a hidden "trashes" file. To permanently delete it off the stick, you'll need to push commandshiftdelete.
Hope that helps!

Questions about MacBook Pro 13"

Hello,
Im thinking of buying a Macbook Pro for school. Im doing some kind of Graphic Design education and I use a lot of photoshop and adobe programs.
Now I have two questions regarding to this.
What are the advantages of using a Macbook Pro for creative software like Photoshop and programming (like coding a website with html/css/js), over a windows 8 laptop?
I just dont have the money for a 15 inch macbook pro, but will the MacBook pro 13 inch i5 4GB will be fast enough for adobe CS6 and will the screen also be, do-able? Its rather small of coure. But at home I got a LG 27" monitor, which I can connect my laptop to. So 13 inch will only be for at school. Mostly I design behind my 27 inch monitor.
Thanks,
~Mark

No real difference. Both can run Photoshop just as well. It really depends on the amount of RAM installed, the speed of the hard drive and CPU along with the graphics processor.
Then why do so many people use MacBooks? Especialy in the creative industries?
With the Mac you will need a Thunderbolt/Mini Displayport to whatever type of connection your 27" screen has. DVI or HDMI. These adapters cost arount $30 each.
You will also need to factor in the Applecare extended warranty which extends the standard one year hardware warranty to 3 years of coverage, adding 2 years. Without it if that Mac fails after the first year it is very expensive to fix a Mac computer.
How can I be sure a macbook 13 inch can be connected correct and well to my LG 27 inch monitor. My LG is 16:9 by the way. I read some non-apple monitors have compatibility problems
I would highly recommend checking out apple certified refurbished MB Pro's:
Unfortunally thats not available in my country (the Netherlands).
4 GB of memory will not be enough for CS6 regardless of the processor. My advice would be to go with the MB Pro and upgrade to 16 GB memory. Memory acts as a bottleneck for processing speed. The more memory you have, the more power you will be able to get out of your processor. From personal experience, I can tell you running a late 2011 MB pro (i7 2.2 GHz quad core processor), CS5 was crashing with even 8 GB memory. Since upgrading to 16 GB, it has run amazingly well.
I have a friend with 4GB, a dual core CPU and the HD3000 GPU, he runs Adobe CS6 just well. How is this possible there are so many differnt opinions on this matter?
Thanks for all the reply's btw.

A few questions about Macbook Pro 13inch batteries.

Hey, my Macbook Pro just arrived today, and I was wondering about general battery care:
Is it okay to leave it plugged in while using it?
How come there's a longer power cord and a shorter one? Is it just for convenience?
How long does a Macbook usually take to charge to 100%?
Is it okay to leave it plugged in all night?
Sorry if I sound stupid, but I'm not very tech-savvy. Thanks for any help!
xx

Yes, you can leave it plugged in. Once in a while however, you have to use it under it's own power, at least till it reaches 80% to keep your battery in optimal condition.
As for the power cord, you answered that one yourself " for convenience "
How long does it take long to charge all depends on how low the battery was when you charged it.
Yes, it's ok to leave your Macbook plugged in all night. Just make sure you use it under it's own power once in a while. You don't have to fully discharge it which might do more harm than good.

Maybe a dumb question, about which power connectors to use, but....

This may sound like an incredibly dumb question, but here goes anyway....
I upgraded my system a few weeks ago, and will be slapping in a new ATI X850 Pro AGP card in a few days. My current graphics card is a p.o.s. Radeon 9550, so it doesn't have its own power connector or even a fan. My PSU is a dual-rail Antec model, and I'm wondering if it should matter any about how many or which devices I have connected to each power cable set. My psu came with cables to attach, only 2 of the 4 though are the 4-pin molex - the other 2 are pci-e power connectors I believe. Should it make a difference which or how many devices I connect to each cable? For ease of plugging in, I believe my DVDRW and CDRom are using 1 cable, and my ide drive and floppy are using the other cable. Also, I have a pci fan and a case fan running off 1 or the other. I'm likely to jump the power cable for the video card off the one the hard drive is using, unless someone has some suggestion to offer to the contrary.
If it makes a difference, can anyone recommend how they would have them connect?
My list of devices to plug in would be:
1)IDE HDD
2)Floppy
3)CDRom
4)DVDRW
5)Case Fan
6)PCI Fan
7)Video Card
Thanks for any thoughts! SAB - you seem to be the man on builds.....any ideas?

Well, I put the new card in and connected it on a cable with the optical drives. Also, I had unwittingly connected my cdrom on the same ide channel as my hdd , so I changed that so both optical drives are on the secondary ide.
So far, so good. 3dMark03 jumped up from 3300 with an overclocked Radeon 9550 to 10570 with the stock Radeon 850 Pro
I wish I could find some local source to purchase additional molex cords for my Antec SmartPower 2.0 psu, though - I've got 2 more 'outlets' just sitting there on the psu doing nothing, because the other cables are for pci-e, and I'm not using pci-e...... If I could buy some additional molex cables to plug in like the ones that came with it, I could have the vid card on its own cable....

Question about macbook air connecting to the tv

Hi there,
I have a macbook air and a non-HDMI tv I recently procured from Goodwill. What do I need to buy in terms of cords, etc... to connect my Mac to my tv?
Thanks!

You should also ask this in the MacBook Air forum. This is the forum for the white and black plastic MacBooks that were discontinued in 2010. You should also post this question there to increase your chances of getting an answer.

Question about the Power adapter

I just got my Macbook and I love it but I'm a bit confused as to the function of the power adapter. I plugged it in and it started to charge my battery. Is this supposed to happen? I thought the function of the adapter was to provide continuous power from an outlet supply. Maybe I'm under the impression that the second cord I received with my macbook is a power supply cord. Is it?

Also You can run the computer without your battery in but I believe it's not good for the computer.
This link explains the point you were making. MacBook reduces processor speed when battery is removed while operating from an A/C adaptor

Question about MagSafe Power Adapter

I just got a new magsafe power adapter and wanted to know if leaving it connected to the electricity for too long damage it?
Last question, my battery is dead, should I take it off andrun on the adapter, or just leave the battery on?
A friend of mine told me tht "dead batteries" ruin power adapter?
Thanks all

I'm afraid you should buy a new battery, Frank.
Running on the power adaptor alone will slow down your MBP. - see http://support.apple.com/kb/HT2332
Running with a seriously defective battery installed, though, may not only place a heavy load on your adaptor but may result in the battery deforming (causing other damage) or worse.
Leaving your adaptor plugged into the power when not being used probably won't hurt it, but it will use more electricity than a fluoro lightbulb.

I have a question about Macbook Pro system preferences...

When I first got my Macbook Pro, I thought it was cool to have my computer "talk" to me when I had notifications. For example, when I have an update available, it will say, "Stephen, updates are available." Or when my battery is low, it will say, "Stephen, you are now running on reserve battery power." I cannot figure out how to turn this feature off. Can anyone help me out?

Few Questions about macbook pros

Is the transition from windows to mac easy or does it take awhile?
Did you previous windows users get used to the minimizing of windows,I find it alittle weird?
Another question,Why do people ask if they should get a macbook or macbook pro if price and screen size isn't an issue?Is there some sort of difference?
What is Rosetta?
How many windows can you have minimized?
Are the widgets I see on apple's site the only ones that are out or are there more?
I do alot of downloading,will macbook be perfect for this?
When people say mac doesn't have viruses,does that mean because not many people use mac or because it has a well built OS?
Is there spyware for macs?

Is the transition from windows to mac easy or does it
take awhile?
It depends how long you have been using windows....
How many windows can you have minimized?
Lots, and then some
Are the widgets I see on apple's site the only ones
that are out or are there more?
there are more out there but I am sure most are listed on Apple's site
I do alot of downloading,will macbook be perfect for
this?
It depends what you mean by downloading. If you mean you download a lot of software/music/movies etc illegally using PTP, MIRC, Torrents etc, then I would say no: it is generally more straight forward on Windows, so I've heard.
When people say mac doesn't have viruses,does that
mean because not many people use mac or because it
has a well built OS?
possibly a bit of both but I reckon it's mainly because people don't bother making viruses for macs (yet....)
