Sleep phantom power drain

I have a strange power drain with my 17" MBP (2010 10.6.4/i7/8GB/500GB 7.2k)
When I have the computer in sleep mode (screen closed, nothing plugged in), the battery drains about 1%/hr, when I have it off, it drains at most 1%/day. I've "re-calibrated" the battery a couple of times now, and in normal use battery life seems fine, "wake for network access" is off, and there's no bluetooth keyboard or mouse paired with it. Anyone have any ideas what might be going on?
Thanks,
Paul

What you are exprence-ing in the delay of your SOUNDCARD trying to genarate the time it moves from the S/CARD the COMPUTER
Its called LATENCY which is only normal. At the stage you are at. Meaning setting up your microphone.
Untill you compansate for it by Adjust-ing the buffer size on A Higher rate that is on right. Now lets say its on 128.
Try going higher maybe 512, then try to match up,
what sounds BANG ON.

  • Massive power drain after Belle Refresh update on ...

    Hello
    From being a minor annoyance the massive power drain from my N8 after Belle Refresh update is now a big problem!
    The battery does not even last a full day now
    No apps running - power save on, but to no avail.
    After advice from Nokia Support I've tried to reinstall Belle Refresh again from Nokia Suite, but it didn't make a difference.
    What else can be done? Is it possible to uninstall Belle Refresh completely?
    Some have suggested it is because of the weather widget. Any confirmation from Nokia on that issue?

    I have Belle refresh for over a month now and I keep running the weather widget permanently on first screen. Overall the power consumption is the same as before on Anna (I skipped the first Belle incarnation).
    The only particular thing here is that I flashed clean the full 111.40.1511 version for my phone language. All I can tell is that in the first days after flashing the power drain was significant, merely because of intense phone usage, part of various customizations or just by curiosity. Since then the power consumption has slowly came back to "normal" for my daily usage habits.
    Currently running widgets: clock, profile, weather, next coming event, BBC feed, WiFi, 3G, data usage counter, Nokia Battery Monitor, locations near me. Also Nokia Sleeping Screen is active. I gave up in using email widgets because I only use IMAP manual fetch mode and in this mode they are completely useless.

  • Macbook shuts down rather than sleeps on battery drain

    If I allow the macbook to go to sleep from the battery being drained, it completely shuts off and fully restarts when plugged in (it's non-responsive, and I have to press the power button to turn it on). This doesn't matter if I plug it in immediately after battery is drained or any amount of time longer. Any ideas?
    I've used several other macs that come back from power failure sleep just fine... could mine be faulty?
    Thanks for any help!

    Thanks for the response! I actually tried resetting the PRAM and it seems to be working okay now, but I've only let it go to sleep from power failure once.

  • Put to Sleep, or Power off?

    Is it best for me to put my iPod Touch to sleep or power it off when I'm not using it?

    are you sure? i read that turning off the iPod completely (and on again) actually drains the battery more.
    since i read that (in a battery saving tips thread) i always leave mine sleeping. my battery behaves fine, it does get low after i've listened to a 3.5 hour radio show via wifi on the BBC iPlayer, or play power consuming games, but wifi/gaming does take up battery.
    i do use it on pretty much a daily basis, and sync it (thus charge it, even a little bit) most days, but sleep mode works just fine for me.
    i'd say if you aren't using it for a long period of time then powering off is probably better for it. otherwise sleep mode is definitely the way forward. (apart from anything else, loading the iPod touch up from scratch, takes a good few minutes, which can be a little grating if you want instant access to your music!)

  • Reboot issues recovering from power drain.

    Hi,
    Am a new user of MacbookPro13'', Mac OS X V10.7.3.
    From the last two times my macbook does not reboot after a power drain. Post power drain when i put the power adapter back on and turn it on using the power button, shows a white screem with status bars showing rebooting status.
    The bars light upto about 70% and then it gets struck and gives a repeating double beep sound with sleep light on base right glowing bright.
    To restart i have to force shut keeping power button pressed for 5 seconds and then do a normal power boot.
    What should i be fixing?
    Regards

    Don't drain the battery all the way. That's very hard on the battery, aging it prematurely and causing the problem you're seeing. Plug it into AC power well before it runs out of juice.

  • Do i need phantom power for a condenser mic to use with garageband?

    i have learned condenser mics need phantom power. if i would hook up a MXL 900 series condenser to my MacBook via an XLR to 1/8" cable, would it work? does garageband have some sort of amplification plug-in? or would i need some sort of mixer or otehr phantom power device for it to work?
    MacBook 2.0gHz (White)   Mac OS X (10.4.8)  

    condenser mics need phantom power to work at all, it has nothing to do with amplification.
    you need an interface or mixer that supplies phantom power, or an external phantom power supply to use your condenser mic.

  • Logic Will Randomly Lose Phantom Power

    I have an Apogee One running into Logic Studio 9. On the Apogee One, I am running and XLR cable to an Apex Microphone, and a 1/4" cable to a guitar (At Different times). When recording either the Guitar, but most commonly with the Phantom Power on the 48V Input, the Microphone will drop out temporarily and not pick up any sound, then slowly it will fade back in. This happens every couple of minutes during a recording. We have already replaced the Apogee One, but the issue still seems to occur.
    Any Suggestions?

    Hi
    This sounds like an issue with the audio interface, not Logic. Does the interface work ok on another computer? If it can, run it with a separate power supply, rather than bus-powering from the Mac.

  • 3GS Fast Power Drain, USB Recharge Very Slow, Unit Stops Responding

    3GS running IOS5
    Mid afternoon yesterday noticed the battery was extremely low and figured it was because I hadn't charged it after it had been on the bed side table all night. 
    Typically it's plugged into a USB port most of the time at the home office and this was the first time it had not been charged first thing in the morning.
    It never fully charged, obtaining only about 70-80% charge before the end of the day when is was removed from the USB.  Woke up this morning and the phone had no charge at all.  It displayed the 'plug it into an electrical source' glyph when the main button was pressed. Plugged it into the USB port it has always used and after reading the forums for a while switched it to directly into an external power source. It's now charging at a good rate.
    However, when connected via USB yesterday, and directly into a wall power socket today, the phone emits a bleat similar to the sound made by a USB connection being acquired, but only a single audible sound, not the dual USB type bleats.  It did this yesterday and it seemed to be coordinated with it loosing and reacquiring the USB connection which occurred several times an hour. Now I can't figure out why it's making the sound, but it's doing so about every three minutes and a half minutes, (3:23, 3:27, 3:22).
    When attempting to use the phone in any way at all if fails:
    - When attempting to make a call, after selecting a contact and initiating the call, it displays 'calling mobile...', but no connection is made.  It never rings through and indicates any other type of response before shutting down. (When testing, the calls are received and answered but no connection was ever made.  Incoming calls are not being received.)
    - When reading a news feed it shuts off after a couple of minutes and when re-activated, it has forgotten where it was positioned. 
    - When accessing Settings and making changes, it will die, but does remember the changes made before dieing but may be ignoring the changes made.  After deactivating notifications on the few that were being used.  The unit indicated they had been deactivated but notifications were still being displayed.
    After each of these occur, the 3GS unit just dies and displays the apple icon for a minute or so during which the phone can not be reactivated.
    Have not had any major issues with the unit since I began using it.
    Am aware of the current power drain problems after the IOS5 upgrade and did the upgrade on the first day it came out, but have not encountered any of the stated problems before yesterday.  No software updates were authorized yesterday. 

    Ok, First off, this is now a concluded matter.  The full restore worked and all is back to the way it was two days ago.  Have no idea what might have caused the problem but after talking with a few associates, one did encounter a similar problem but it required no work to remedy. 
    For any reading this with a intentions of using it as a template to resolve problems, here's where I got the information: Using iPhone Recovery Mode

  • I just added two external firewire drives and they keep going to sleep.  I did not have this problem when USB.  I have turned off "put disks to sleep" in power preference.

    I just added two external firewire drives and they keep going to sleep.  I did not have this problem when using USB external drives.  I have turned off "put disks to sleep" in power preference.

    It is not clear if these are the same drives, just connected
    differently, or different drives?
    One thing that may be happening is that the drives firmware
    itself is putting it to sleep when inactive.  Many drives on
    the market have ths feature and it is turned on by default
    and require a drive utility from the manufacturer to disable it.

  • M-Audio Firewire 410 phantom power

    Hi
    I have a condenser mic and wish to use it with my m-audio firewire 410. I have tried everythiong to get it working but no luck. The phantom power has no effect. There is no levels when tested on the m-audio box. What will make the mic work. I believe it to be more the hardware than the software
    Cheers!

    i suppose you have pressed the button on the left(phantom power) of the interface and you see it on (red),right?
    do you have selected the mic instead of line in the front?
    do you have the pad pressed by mistake?
    move the gain pot to see levels?
    if the above are correct you should have sound.

  • T60 Microphone input: Stereo? Mono? Phantom power?

    Hello,
    Does anyone understand the T60 mic input. It seems to me that it a mono input, but if you plug a stereo cable in it, the middle ring on the cable actually gives a 5 volt reading if you put a volt meter across the middle ring and ground. Is this possibly some sort of phantom power and wouldn't this be shorted out if you plugged a mono plug into it? I would think that shorting a power source would be a bad thing.
    Thanks for anyone's help,
    John

    It's a mono input, and it is worthless in my opinion.  The 5 folts is probably spurious, and shouldn't be there.  If you have tried to record direct from this input, you will probably hear a load of noise in the recording.
    At least, that's what I get on mine. Really made me angry, as I had to buy a Soundblaster add-on card to get decent recording.
    Phantom power is generally a lot higher than 5 volts, but a lot of things in computers run on 5 volts.

  • I need help interface/phantom power

    i'm going to be purchasing the nt2-a studio condenser microphone but i'm under the impression i will be needing to buy an interface, could which interface i get affect audio quality etc, i will only ever be using one microphone at a time.
    Which interface should i get and what should i know as i've only worked with usb microphones before?
    Do i need to buy a phantom power also?
    Do i need to spend 100 odd on an interface or will this work http://www.ebay.co.uk/itm/XLR-to-USB-Interface-convertor-with-48v-Preamp-phantom-power-/16 1105081721?pt=UK_Musical_Instruments_Preamps&hash=item25829c7579
    What is my cheapest option?

    I must confess that I'm slightly at a loss to understand why you want to purchase one of the quietest condensor mics around and then feed it into a piece of junk like that ebay item. The mic will considerably out-perform it. Yes, you need phantom power for this mic, but if you want to use it to anything like its capability, then you'll need rather more than the cheapest usb interface for it.
    You'd be better served by the (cheaper) Behringer Xenyx 302 USB Mixer and interface, or for not much more, the ART USBMix 3 Channel Mixer w/ USB Audio & Phantom Power. Even though I'm personally not a huge fan of Behringer, either of these will do a better job, because the preamps in them aren't anywhere near as compromised. At this price level though, (only 16-bit A-D) you still won't be able to get the full benefit from it. To do that, you're going to need a more expensive system with a better converter.

  • Power drain - app?

    Hello to all. Perhaps someone can help?
    I am concerned about the power drain of my playbook. I always have in on charge, but what if I forget and leave it on standby and it drains down? I have read the horror stories of owners attempting to power from a dead battery.  There appears to be no fail-safe cut off before the battery drains away.
    Excuse my ignorance in asking the below questions.
    Do the owners of Blackberry phone's have the same trouble? Do their phone's switch off before they lose their power, as does and Android, and any other phone's operating system. Basically the message states that the phone is switching off to conserve power and the phone needs to be put on charge.
    Is there an app that can be purchased to operate the discharge of the battery?
    Is there any apps being written for such a thing.  I think every owner of a Playbook would jump on the app to purchase if it were available.
    Regards to all (except BB)

    Not a Dev but I have some advice...
    Before entering Stand By mode (clicking on the battery icon and selecting) click on the gear icon and select Airplane Mode (under About) and then swipe to set this feature to on.
    Close screen
    Then enter Stand By mode.
    This will terminate your Wi-Fi connections and Bluetooth connections if they're on. These are the two biggest "drains" on the PlayBook (besides the screen itself). I think people don't realize that when they put their tablets into Stand By that the radios and their connections are still chugging away pinging servers and doing whatever it is they do. Apps are still running in the background even..The only thing this really does is prevent a full reboot and keeps the screen off.
    So by doing this one simple thing (granted it is a bit of a PITA but it is VERY useful) your battery issues will cease to be a problem unless you willfully let your tablet's charge level get below a suitable power threshold.
    Try it for a day and let me know what you think...
    By the way, I haven't let my cellphone (Torch 9810) ever discharge all the way down to find out if it auto shuts down or not so I can't answer what actually happens.
    I do think a setting could be coded into the PlayBook's OS that you had some control over. I don't see this happening before BB OS 10 and we don't know how that will work until it launches.
    An application would be helpful but not required in my opinion.
