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.

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.

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.

Where do I find the power adapter for my Cinema Display?

I have recently aquired an older style of an Apple Cinema display. It didn't come with a power adapter, just the DVI cable coming out the back. I have done some research and understand that power and usb and video signal come through this one cable, but I have also come to know there is supposed to be a converter power box type thing between the display and the monitor. I can find boxes similar to the one I believe I need on Ebay and other sites, but not the exact one. They vary in style somewhat. Wondering if someone could steer me in the direction of where to get one and help me understand more of what I need and how it all works? The model/serial number on the monitor is CY3041XSLFA, it's a 23" Cinema HD Display, made in 2002. - Thanks -

If the display uses the Apple Display Connector (ADC)
<http://upload.wikimedia.org/wikipedia/commons/thumb/0/09/AppleDisplayConnector.j pg/800px-AppleDisplayConnector.jpg>
you will need a DVI to ADC adapter.

HP S3120N. I replaced the motherboard, and the power supply, now the recovery discs wont work.

I am a not so proud owner of a HP Pavillion S3120N. I am running windows vista home edition. The motherboard went out, so I replaced it with a Zotac GeForce 8200-ITX Wifi Series. Now the computer says it is noa a valid hp solution, and the recovery discs do not work. is there a way to fix this problem without buying a new operating system?
This question was solved.
View Solution.

Yes, return the Zotac motherboard and get a HP/Compaq OEM M2NC51-AR / HematiteXL-GL8E motherboard. I know that isn't the answer you want to hear but the recovery discs are locked to a specific set of HP/Compaq machines with specific HP OEM motherboards. Outside of that, you will need to purchase a new OS.

My ipad2 crashes when it is removed from the power supply. It can't be reset?

My ipad2 crashes when it is removed from the power supply. It can't be reset? Doesn't respond when plugged into my pc?

Hrm... that may be true and this may be a function of the phone email client that Apple just doesn't do.
No, I can easily MANUALLY delete the messages. I would prefer if I didn't have to do it twice, tho. Once on the mail server and once on the phone.
What I think the phone needs to do is, when it checks the POP, anything NOT there should be removed locally. I think you are correct on POP; the phone will poll the mx (mail exchanger) and the mx will pass off the messages to the phone. The phone then keeps ALL of that unitl you manually delete it.
If, say, I remove a message from the mx, I would like the phone, when next polls, to see that that particular message isn't on the server anymore and remove it locally.
Perhaps it's just me but if I delete the message on the mx itself, via my ISP's webmail interface, I really don't want to have to remove it again from my phone.
thxs!

Mac Pro won't start up. What's the best way to check the power supply?

Hello. I'm having a severe problem with my 2007 Mac Pro. The symptoms are very easy to describe. The computer apparently shut itself off overnight, and when I press the power button to turn it on, absolutely nothing happens. No lights, no chime, no signs of any power whatsoever in the computer. I have never had major problems with the computer before. (Although I had recently noticed some minor skipping problems with streaming videos and Firefox had started hanging occasionally.)
So far, I have checked the power cable and the power outlet. I have also reset the SMC (holding in the Power button for 5 seconds with the unit unplugged). I am unable to see any light in the diagnostic LEDs (including LED 1) when I press the DIAG_LED button on the logic board.
While I welcome other suggestions, all I can figure is that this is either a power supply problem or a major logic board failure, but I don't know which. I have a multimeter and would like to test very directly if the power supply is the problem, because they are very expensive and obviously I do not want to order a replacement supply if it would not fix the computer. Does anyone know what the best way to test the supply directly is? What pins on what cable should I test, and what voltage should I look for?
Also: No the computer is not under any warranty. If at all possible, I would like to fix this myself. Thanks for any help you can give.

Well, I may have found the answer to my question as to why replacing the fuse dows not seem to be encouraged. I cut out the failed fuse (fast fuse, ceramic, 16 Amp 250V), and replaced it with another that was as close to it in spec as I could find (15 A instead of 16). Then I put the supply back in the case.
When I tried to plug it in, I got an immediate spark, followed by an acrid smell from the power supply. Later inspection revealed that the new fuse blew, as did another component nearby (not sure what it was) where I could see blackening and the smell was concentrated. At this point, I would consider myself lucky if the power supply didn't take anything else on the computer out with it.
Lesson learned; will try a new power supply and go from there.

Battery Life is short and when i do charge the power supply gets to hot to touch?

Hi! I'm not sure whats Wrong with my MacBook Pro 15" - Mid 2010, i7, 4gb RAM, 512mb Graphics.
When i charge my MB it has a really short life (50 - 60 min) without using high demanding programs. I've had a look in system information and i found this; Full Charge Capacity (mAh): 4858
im not sure what it should be but does it sound like a healthy battery?
My second question, the power supply is hot to touch is this a contributing factor? I took it in to apple and they suggested to buy a new charger, so £65 later and i still have the overheating of the power supply and the short battery life problems, HELP!

That is not a good sign. Check the connection on the MBP to see if there is any foreign matter or discoloration evident.
Open System Information>Power and post this from your MBP:
(make certain that the charger is attached)
Also run an Apple Hardware Test. You may use the appropriate original install disk for this which has the AHT instructions printed on it.
Note that an error free AHT is not definitive.
Ciao.

Understanding the Power Supply?

I hope I can get help identifying a problem within the power supply on my Mac G4 DA computer.
First let me say that I have ordered a new power supply unit from a reputable dealer. However, I wish to identify and understand the problem, and hopefully make a repair with the intent of keeping it as a spare unit. I would also mention that I fully understand the dangers involved in working with potential high voltage.
What happens, is that the six-year old computer works well for about 10 minutes, then a noticeable speed change starts to occur at the Power supply. When the speed drops lower, something within the power supply starts an annoying vibration or humming that will persist until the computer is put to sleep for a few minutes. On restart the problem noise is gone, until the computer works for the usual time and then the speed starts to drop and the noise reoccurs. The noise and vibration are louder than I would expect from the fan, especially when running slow?
I believe it is an energy-saving feature of the Power Supply to lower speed when there is no great demand placed upon the computer (when it is idling). I'm finding it difficult to determine if it is specifically the fan that sets up the vibration or something else in the power supply. The fan is a replaceable item, but beyond that there would seem little I could do in the way of repairs.
Do any of you have any thoughts on this?
Thanks in advance

Hi, Barry!
Insure that the PSU case is relatively clean.
Disconnect the power cord. Using a pin oiler, place a tiny bit of fine lubricant at the base of the fan shaft and then see if the noise resolves. If it does, the fan bearing is likely worn or insufficiently lubricated.

HT2811 If the display flashed short long short could the power supply be bad?

If the display flashed short long short could the power supply be bad?

Hello,
In order to determine what might be going on, I am going to need a little more information about your setup such as:
-what version of the cFP drivers are you using?
-where/what device are you outputting voltage to? at what voltage? how much current do those devices require?
-could you explain further by what is meant by '[at] approximately 30 seconds, all channels on that PWM shut off'. Are the lights on the modules still illuminated when the system 'shuts off' or do they remain on?
-Do you have another power supply you could try this with?
-Does the power supply meet the specifications for use with this module per p. 4 and 5 of the FIELDPOINT AND SPECIFICATIONS™ OPERATING INSTRUCTIONS FP-PWM-520 and cFP-PWM-520 Eight-Channel, 5 V...
-Does the power supply continue to output 24VDC even after the 'shut down'?

Is there any way to change the power supply on a hp elite 8100 sff

hello . Is there any way to upgrade the power supply from the standerd 240W psu . the pc is a hp elite 8100 sff ( quad i7 2.8ghz nvidia quadro 295 nvs and 8 gb ram )

Joleney-
I do not know of any way to turn off the Sleep button. If yours does not work, there might be an internal problem like a loose connection in the iPad.
One thing you can try is to hold both the Home and Sleep buttons for several seconds until the Apple logo appears. Ignore the "Slide to power off" arrow if it appears. If successful, the iPad will restart after a couple of minutes.
If the Apple logo never appears, it is likely your Sleep button is bad. If the iPad is still in warranty, show it to an Apple Store Genius. You may get a replacement iPad if the Genius can not fix it.
If the iPad is out of warranty or there is no Apple Store near you, look for an Apple Authorized Repair Center near you. There may be one in your city. If out of warranty, the cost of a repair would most likely be less than Apple's replacement price. <Apple Authorized Repair Centers>
