Why is the power supply for the Mini so big?e

Can anyone explain why the power supply / adapter for the mac mini is so big compared to the power adapters for the macbook? The processor and hard drive for the mini is the same as those for the macbook, so why is the power brick so much bigger? Just curious.

While I doubt anyone who knows for sure will be prepared to pop up and answer, I suspect the reason is two-fold: firstly that the supply is engineered for constant use, 24/7, where laptop supplies are not, and thus it is larger because the components are more rugged and over-specced, and secondly for lowest cost, since it is cheaper to engineer a larger product of this kind than a smaller one, due to the premium cost of the smallest narrow-tolerance components.

Is the power supply for iPhone 3G only 120v?

Is the power supply for iPhone 3G only 120V

This is all true.
The iphone 3G can only be updated to 4.2.1. It will not support any version higher than that.

If plugged into the power supply, should the Cinema Display A1081 standby light come on without being plugged into a mac

I was given an old Cinema Display A1081 a few years ago. I am trying to test it and want to know if plugged into the power supply, should the standby light come on without being plugged into a mac? I don't want to buy a DVI to mini display adapter if it isn't working. One thing I did do was plug Monitor power in and then the USB plulg into my PC laptop and my iPhone charger USB plug into the back of the monitor. I am able to charge my iPhone this way so I know that the power supply is working. But I can't tell if the monitor itself is workign as no ligths are on. (PS: I am purchasing my first Mac so I am a complete newb but very proficient with PCs) Thanks so much for your help.

Just a final question about Sleep mode - does this have any negative effects on the life or performance of the laptop? I'm so used to Shutting down the laptop each day that I worry about Sleep mode having some sort of drain on the components or something.
There are only two practical differences between Sleep and Shut Down:
1. Sleep will wake instantly, so you don't have to wait for startup.
2. Sleep will drain a new, fully charged battery after several days without being woken or plugged in. If you shut down, the battery charge lasts much longer. Obviously, if you only sleep it overnight, you'll still have plenty of battery left in the morning.
Don't sleep it more frequently than necessary, though. Frequently turning the backlight and hard drive off and on can shorten their life. Just do what's reasonable. I usually leave mine awake until I have to transport it in a bag, along with sleeping it overnight. On battery, I'll sleep it more often to preserve battery.

How to change the power supply to the CD/DVD Drive so that it is off by default?

When running on battery I often use the "Safely Remove Hardware" icon from XP to "unplug" the Mat****a CD/DVD drive in order to safe some battery life.(Does it?) I use Fn+Tab to bring it back to life. I wonder if there is a way to make my Notebook (M400) boot with the power supply to the Drive off by default. By the way, any idea where I can find the extra battery for the CD/DVD-Drive slot and at which price?
Thanks in advance for your help.

Hello Robert
If you check start page you will see that this support forum is not any kind of Toshiba support directly but user-to-user forum. But you are not alone and many users expect that some Toshiba support team sit in the office and wait to write answers.
Anyway there are many Toshiba notebook users with very good knowledge and also enthusiasts who try to help other guys with different issues and also share own experience.
Professionalism is not forum but action when you need assistance because of hardware damage or something similar. If you need competent answers and help every authorized service partner should be able to give you info you need. But please dont mix service partner and Toshiba because it is not the same.
Anyway I have found info that you can use additional (second expansion battery) and it should be batteries with part numbers PA3510U-1BAL and PA3510U-1BRL. I can not tell you how much it costs but you can find it alone using Google.
Back to your first question: If I am understand you right you want to save more power and because of that you want to disconnect ODD. It is nice idea but you have obviously misunderstood something. "Safely Remove Hardware option is there to help operating system and say this hardware part will be removed and dont exist anymore but it does not mean physically disconnection from other hardware.
If you need more power use second battery and enjoy your life.
If you have more questions you are welcome. Many users here have M400 and I hope in the future some of them will participate a little bit more.
Have a nice day! :)

My 27" Imac (A1312/EMC2390) keeps shutting down unexpectedly with no warning or "screen of death". I replaced the power supply, reset the SMC, and zapped the PRAM, but the problem continues. Can anyone help me?

My 27" Imac (A1312/EMC2390) keeps shutting down unexpectedly with no warning or "screen of death". So far I reset the SMC, and zapped the PRAM. I even replaced the power supply but the problem continues. My error and system logs seem unhelpful too. Can anyone help me out?

You can get a shutdown like that if the computer gets too hot. Make sure the air intakes on the bottom and the exhaust vent on the top are clean and are not blocked by something in your workspace like papers or the back of the computer being too close to part of the furniture. You need a good six inches (15cm) of clearance between the exhaust slot and other objects or surfaces.
Anti-virus/internet security software, especially the "pay for" kinds, can increase operating temps. So can third-party backup software furnished with many "name-brand" external hard drives.
Fan motors and/or temperature sensors can fail. If you have the original grey disks that shipped with your iMac, find the on that has Apple Hardware Test (AHT) and run it. If you have a failed heat sensor or fan motor, it will detect it with an error code containing "SNS" if it's a bad sensor or "MOT" if its a bad fan motor.

When I connect my MacBook Air to iPads through a powered USB hub the power cord for the hub explodes and trips the fuse on the building. I've tried different iPads, cords, power points to no avail.

When I connect my mac air to some iPads through a powered USB hub for VPP/Configurator, the power point for the hub blows out (tripping the fuse in the building). I've tried different iPads, cords, power points and of course hubs. Also the computer has a habit of shutting down when any type of USB device is removed from it. Does anyone have any suggestions?

I've done some experimenting, and this is what I've found out:
1) The problem persists when I reformatted the USB HDD devices to ExFAT, so the problem apparently wasn't due to NTFS for Mac OS X by Paragon.
2) The problem persists even when BackBlaze is paused, so I don't think that it's due to BackBlaze.
3) The internet cuts out as soon as data begins transferring either to or from a USB HDD device and won't reconnected until I eject and unplug the device.
4) The problem affects data transfers through either USB port.

I need help to replace my power supply for the hp pavilion elite m9510f

This computer has given me many problems since I bought it in '09. From graphic card fan issues, a hard drive crash, and now the power supply has failed.
I did the blow dryer trick but it still ends up breaking a week later. I want to know what new power supply should I buy. One that will be able to fit in the hp pavilion elite m9510f and is an upgrade to the 350w that it has. Maybe somthing under 60-70 dollars if possible. Thanks for any help.

It appears to be a normal case and motherboard. A normal ATX supply should work: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=50001333&IsNodeId=1&Description=Computer...
Just an example of what is availble, but most any should work as long the physical dimensions match the one installed now.

Trouble replacing the power supply for a 20" imac g5

I have purchased a new power supply and going through the replacement instructions but I cannot get the cable to disconnect. In the instructions it says
4. Disconnect the power supply cable by pressing the connector release tab and using a
wide, flat blade screwdriver to pry apart the connector.
5. With your fingers, pry the cable off the connector.
But the parts simply will not come apart and the plastic is just getting all mangled and making it more difficult. Is there some sort of trick to this?

Don't keep forcing anything or you'll end up having to replace those cables/connectors.
This is what I might try, however, I have to say I have never had to do this and maybe someone who has will have a better idea: You might try dribbling an extremely tiny amount of silicone spray downwards into the connector. Don't allow it to get on the outside of the connector where you need to grip it. And don't spray the silicone directly; first accumulate a little in a small container (one of those small cough syrup measuring cups would do), then try to get some on something that will hold only one or two drops and feed it in from there. I don't think it will reduce the conductivity of the contacts, but try to keep it only on the plastic, if possible. Shake the can of silicone spray well before using.
You might also try using a small piece of a non-slide rubber mesh pad, the kind used under rugs, to help grip the connector better. And jiggle it a little from side to side while pulling it out.

How can I replace the power supply IN the time capsule

I have a TimeCapsule that has a bad powersupply. I have opened the timecapsule to confirm this. Has anyone done this before? If so, where did the power supply come from? Cost? I took this to the Apple Igneous bar and they said there is nothing that can be done about it.They said it couldn't even be opened, but simply peeling the rubber bottom off and unscrewing a number of tiny screws and that's it. The 1 TB drive is LOOSE in there. That was a bit of a surprise. I had thought that the issue was the drive itself was bad. I had hoped that if I removed that the AP part would at least work, but after opening it up and firing it up I could hear that the power supply was buzzing thus the conclusion it was the issue.
I am going to put the SATA drive in a reader to see that it is indeed ok. If that checks out, then I know for certain it is the power supply, but I don't know what to use as a sub since the unit needs both 12V and 5V. I'd just as soon find a good supply and use that. Any help would be appreciated.
Thanks,
John A Kostelac

What version is your TC.. A1xxx from the rubber foot?
Power supplies are not available from apple. They do not consider it repairable. It is a sealed consumable.
Power supplies are available from ebay.. simply type time capsule power supply into search.
This is absolutely standard issue that has been ongoing for ages and ages.
See https://sites.google.com/site/lapastenague/a-deconstruction-of-routers-and-modem s/apple-time-capsule-repair
For a multitude of ways to fix it.
The 1 TB drive is LOOSE in there.
No, it is not loose, it has rubber mounts with pins in the bottom base plate. You cannot see the mount points with the base off. This is standard hdd mount for low noise and vibration.
I had thought that the issue was the drive itself was bad.
Drives seldom are the problem. The Gen2 WD black has been less than great though.. and later spinpoint in Gen3 not so good.

Can I use adapter of the iphone (not the cable), to attach the power cable of a macbook pro bought in Canada? The power adpter for the macbook pro is two pins because it was bought in Canada. Thank you.

Hi! I will get a macbook pro bought in Canada soon. Can I use the adapter plug of my iphone (ireland) not the cable, as the adapter to plug my macbook? The power adpter of the macbook from Canada is a two pin. Thanks for any help.

I wouldn't, the Mac draws significantly more power than the iPhone. Why risk it.

Does Mac still sell the power cables for the late 2005 version of these?

I recently purchased a PowerMac but the pervious owner did not have the power cable. I assumed it would be no problem and that I could take a power cord from one of my other Macs, but I now see that this late 2005 model has a different socket then most macs it is square with horizontaly running bars and looks like [--_--]. I want to know if Mac still makes replacements for these and if they sell them at the Mac stores.
