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! :)

  • 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.

  • 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.

    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.

  • 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>

  • 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'?

  • Display the power supply status in the IPS 4270

    How to display the status of the power supply on the IPS 4270
    since the IPS has two power supplies and one has failed, so i want to check what is causing this failure (i am looking for a message from the CLI describing that the IPS power were failed).

    At this time, there is no method to display the status of the power supply from the CLI or IDM GUI of the IPS-4270.  There is an open enhancement request to have this capability added in a future release of the IPS software.

  • The Power Supply Fan is still working, but does not appear to respond to increased loads, and its speed cannot be increased using SMCFanControl. Any suggestions?

    Hi all - My mac pro 1,1 has an enigmatic problem. It's quad-core, 3Ghz, running OS X 10.7.5. The problem began some months back, when running HD video conferences, HD streaming videos and some other graphics-moderate (I won't say intense) uses, such as slide shows in Just Looking. My machine has an ATY, RadeonX1900 card and 2 monitors - both Apple displays, one being 30 inch 2560x1600, the other being 24 inch 1920x1200.
    When I start those types of graphics-moderate apps, after about 5 minutes, something would crash (the monitors making a noise as it did) and the displays would both go black. The power did not appear to be fully cut off from the monitors. I think that the underlying applications, however, did not crash. So, I could still hear and speak to people during video conferences, and I could hear the sound tracks of videos.
    Attempts to restart the computer and get the monitors back did not immediately work to undo the problem, if done straight away. The only way to correct the problem (so as to have the monitors work) was to wait for a few minutes and then restart.
    After a lot of puzzled looking at console logs (and I confess that I am not an expert), I ran into a blank.
    But, because of the timing of the crashes (after ~5minutes use) and restarts (after some minutes wait), I reasoned that the problem might be temperature related.
    Once on that path of thought, I found this article:
    http://worldtv.com/blog/guides_tutorials/fixing_an_overheating_mac_pro_no_expens e_required.php
    I installed both Temperature Monitor and SMCFanControl. And I experimented, and got interesting results:
    Now to the puzzling bit: SMCFanControl shows that the speed of the Power Supply Fan doesn't vary much, even if I use SMCFanControl to ramp fan speeds right up. All of the other fans react to SMCFanControl, going up to and above 2500rpm when commanded. But the Power Supply Fan does not.  Having watched it for a few days now, the Power Supply Fan, according to AFCFanControl, never varies outside of a range from about 600-640 rpm, regardless of what I do with AFCFanControl.
    Also (and not surprisingly), whenever the graphics-moderate apps run, when I ramp all the fan speeds up using SMCFanControl, Temperature Monitor shows that the all of the temperatures within the machine plummet, except in the power supply locations. Power Supply Location 2 is the worst affected. Because the Power Supply Fan does not react as the other fans do, the "crashes" still occur.
    I could post some screen shots of the read outs of SMCFanControl and Temperature Monitor, although I think I have covered the key points in this post.
    It seems that the Power Supply Fan is still working, but does not respond to increased loads.
    Instinctively, I'm worried that if that's right, it might be a hard problem to fix. Any suggestions? Help! I would really appreciate them!
    Cheers

    Thanks for your response Grant. I had already read about, and I think excluded, dust in graphics card/fan/assembly as a cause. The entire inside of the computer, including the graphics card/fan/assembly, is as clean as a whistle. It looks clean. I've cleaned the dust out every now and then (including a few days ago). Also, my undersanding (derived from the article, linked in my first post) is that I might expect to see high temperatures in the Northbridge and memory module B if the graphics card was overheating. According to Temperature Monitor, however, locations do not increase in temperature when I run the relevant apps. Finally, the graphics card/assembly does not feel too hot to touch.
    It is strange that SMCFanControl lists the Power Supply Fan as being software controllable, if that fan is not. Still, your comments are consistent with my observations, as the fan simply does not respond to software control.
    There are two upsides: First, I've something of a work-around. I've worked out what temperature must be achieved in Power Supply Location 2 for a crash to occur, and I can watch that location in Temperature Monitor, terminating the process before that treshold is reached. Of course, that's not ideal. Second, ramping all the other fans up does significantly delay the onset of the problem, and makes recovery time much quicker.
    Is there any donwside to peridically ramping up the other fans when running the relevant apps? Given that it causes all of the other locations to cool significantly, could this lessesn the life expecancy of the mahcine? (I don't want to run the fans up all the time - that's like sitting next to a jet ready for take off!)
    Also, a correction to my first post: Yesterday, with all the other fans running on full and running an HD streaming video, the Power Supply Fan did, eventually, slowly, come up to ~740rpm, which is much higher than the ~640rpm maximum I had previously seen, and this may have aided delaying the onset of the problem. 
    I'm not sure where this leaves me? The problem might now be able managed. Well, sort-of. But it's not eliminated.

  • 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?

    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.
