Sleep usage question - not problem

Sleep seems to work differntly on my new iMac compared to my old G4 FP iMac.
Question - are these observations below normal?
1. When I used to put my G4 to sleep (by clicking apple/sleep), my G4 would seem to more completely sleep. Even my external Lacie firewire drive wuold turn off its light and shut down. But with my intel iMac, the light on the external drive does not turn off.
2. It seems like the iMac fan is still running after putting it to sleep. When I check the next morning the iMac still seems warm/hot with the fan still running(though amost silently).
3. Also I notice that my G4 would provide the stobing light only when the computer was put to sleep, if the monitor alone was sleeping the strobing light would not flash, but with the intel iMac the strobing light will flash if the monitor has timed to sleep, but the computer has not.
4. I'd also note that I have the preference set to allow hard drive to sleep. And I do find that I can hear the hard drive starting up again (especially the firewire drive) after not using the drive for a while. Nevertheless, the firewire drive light is on all the time.
Thanks for any comments,
Tony

Hi Tony,
Yes, it seems the light (steady or pulsing) "tasks" have changed since the G4 iMacs.
See here:
- http://docs.info.apple.com/article.html?artnum=58016
So it may very well be different again with the new Core Duo iMacs?
Of course your computer is awake and works, if it's only the display sleeping.

  • JButton wont resize - Question not Problem

    Hi,
    I'm wondering if you can give me the reason behind this behaviour.
    If you add a button to a panel, then call setSize(), the button doesn't resize itself on the panel. I've tried setting the setPreferredSize method as well, but the button always stays as the size it was created.
    I know there are work arounds, but how come you cant just set the size of a button on an empty panel?
    Cheers
    Dave

    setSize(...) won't work, because the LayoutManager will override whatever you set. (Although setSize(...) is require when using a null LayoutManager).
    setPreferredSize(...) should work. If it doesn't then you have something wrong with your program.

  • Questions Not Answered. Problems Not Solved.

    Hi,
    I have downloaded and installed Mac OS X Lion.
    During the Installation and usage of the Lion, I have encountered  some problems.
    "I posted these questions and problems on Apple Support, but MOSTLY not answered".
    So, "please, apple tech people'', solve the problems for us...
    I'd be greatly apjpreciated if you could check out my posts(through my Apple ID "EDLIU") and answer my questions.
    Thanks in advance.

    To echo what Michael has just said we're all just people like yourself trying to help each other out.
    I normally display 30 entries per page and if I want to go back to yesterday I have to page back to round about page 30 - that means that many questions are disappearing from the front page. Luckily us helpers seem to span the globe so there's nearly always somebody here trying to help. His day in Australia is my night in the UK

    What can I do to boot?

    Restart with the Option key held down.
    If the internal drive shows up, it's the PRAM battery.
    If it doesn't, insert a compatible Mac OS 9 or X install disk, click the button with the circular arrow, and either repair the internal drive or install a new OS on it. If it doesn't show up in Disk First Aid(9) or the Disk Utility(X), it's either not plugged in or needs to be replaced.

  • Broadband Usage and speed problems.

    Hi.
    I have question about broadband usage.
    Its 11 days and bt website says I used more then 20GB!
    Its nearly 1.8 GB per day! I used Internet for browsing website and receive one email pre day, I download twice large amount (about 1-1,5GB) and nothing more!
    I just wonder what going on? I try monitor my usage day by day from 5 days ago and its worst and worst!!!
    I nothing download but my usage going very fast.
    Its looks like I will be download about 3 movies per day that means I will have now more then 30 movies! Its must be something wrong!
    I used before VM and my average Internet usage was about 15-20GB per Month with solid 10MB speed.
    Now my speed is **bleep** from 8mb to 1mb and sometimes less then 512kb!!! And usage is higher !!!
    How can I see details about my usage?
    And q2
    About speed - in my area BT Infinity will be available from 31.12.2010
    Its mean still BT have same works, it might be cause my slow broadband?
    And from 25.11 till now is same problem with broadband, in three days I must reset BT Hub because there is no Internet. On BT Hub anything looks fine, Is IP address etc... But is no Internet telephone and no Internet as well.
    I check by used ping bbc.co.uk

    Hi.
    I hope you don't mind me asking a few questions, this may help to determine why your usage is as high as you're seeing.
    Do you have more than one computer connected ? Do you use iPlayer, or watch lots of youtube stuff ? Do you have any games machines such as XBox connected to the Internet ?
    Are you uploading lots of things ? uploads count as well as downloads.
    Are you up to date with all security and anti-virus packages, and have you run any scans recently ? (sometimes viruses and trojans can cause a usage problem).
    Your inherent speed problem could be due to various reasons, for example worsening line conditions due to weather and general wear and tear. Strangely viruses can cause a noticeable slow down, but mainly due to the computer being infected rather than the line being slow.
    Can you posssibly post the hub stats ?
    If you're using a PC, download something like Networx usage monitor and see if that can help. Of course it needs to be on each PC, but can't see the usage of games machines or Internet TV (or iPhone use etc).
    I used only 2 machines. Desktop PC and laptop. Laptop very light, just 1-2 hours per day only websurfing (3-5 websites with no movie or high quality images, 90% is just plain text)
    I not download lots of stuff, Like I just say, in VM my average monthly usage was 15-20 GB and I download few movie and lots of music.
    In December I just download one movie other traffic is just webserfing email.
    Youtube - yes I watch, but its not new staff for me, like just say my usage is not deferent then was in VM!
    Now usage monitor on BT web site say I used more then 20GB! in 11 days!!! if one movie will be 0.7GB its means I download about 30 movies!
    Its massive! I never download 30 movies in 2-3 months )
    This start about 5 days ago, when my strip goes to orange. My average Internet usage is 1.8GB !!! Even I for 2 days used Internet very little.
    I nothing upload.
    It is not possible, to anny worm or viruses used so big bandusuage if any software used Internet connection in background (like systems) its just kilobits not gigabits!
    If I will be use very hardly Internet I will be no rise alarm. But I now what I used. I have Internet for more then 7 years and now how far I go.
    And now is very strange - I less used inherent I have more GB used!
    In my calculation if my average usage per day will be 1.8GB I will used 55GB!!! I never used more 20 - max 30GB! It must be something wrong on BT site.
    I get BT Broadband option 2 be cause, I now I used about 15-20GB per months and BT Broadband option 1 is not for me, but 20GB in 11 days!
    We not talk abut 100MB! or 500MB per day we talk about nearly 2GB per day! Its massive!
    Is any chance to get detail Internet usage?
    Q2
    I loose Internet connection 3 times per week, so I need push reset button on hub.
    I left once Hub with no reset but in 5 hours it will still no Internet.
    Its looking very strange, because anything looks OK except I loos Internet phone (no blue telephone light)
    In hub stats is IP, is Downstream etc... but when I ping bbc.co.uk it say: host unavailable or similar.
    After reset working well. My be my Hub is faulty?

  • Ipad dipped in water and sleep/wake button not working properly?

    My son dipped my ipad 2 in the water bucket for like half a second the ipad,before this ipad was out of battery and was off! i quickly took it out dried all the excess water and even used a blow dryer to dry it,after a quick dry i tried to swtich it on and everything is working okay till now except the wake/sleep button,its not locking the screen or not switching off the ipad. it did turned it on but its not locking the screen or turning off the ipad!
    when i tried reseting it from the general menu in settings it turned off and then the apple logo kept on coming for like 5 seconds and then going away this keeps on happening till i dont keep a hold off the sleep/wake button to switch it on or till the ipad runs out of battery,then if i hold the wake/sleep button to turns it.
    One more problem im facing as soon as the ipad turned.it gives me power off option everytime then iv to cancel it to use my ipad.
    so the main question is my sleep and wake button is turning on my device but not working while its on,what would be the problem and whats the solution?
    p.s. i was tensed about it so i quickly turned it on to check whether its working,i know i shouldnt had turned it on :/
    currently my ipad is off and iv put it under a fan to dry,thinking this might might help but im feeling it wont now its too late:(

    Hello:
    Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
    That resets the iPad.  If that does not work, I am afraid it has been damaged by the "water dip."

  • IPhone 6 Battery Usage setting not working.

    When I go to my setting and check my Battery Usage setting it states: "Battery information will be available after using iPhone for a few minutes". I've been using it for hours and I get the same response when I go to the setting. I've turned off my phone multiple times to see if that would resolve it, but it hasn't. Is anyone else experiencing this behavior?

    Hello.
    I have the same problem. iPhone 5, iOS8.0.2, used for a few days - still no usage statistics, only "Battery information will be available after using iPhone for a few minutes".
    I tried restore iPhone (DFU) without restoring backup from iCloud/iTunes, resets, hard-resets, erase all settings, drain battery to 0% and charge to 100% overnight etc. - nothing helps.
    I wrote to the Apple about this problem.
    Here is the page that you can use to contact with Apple and report a bug - https://www.apple.com/feedback/iphone.html
    Please, give the title of "iOS8 battery usage statistics not working" (or something like that), choose the "Bug ​​report" and describe the problem. Perhaps it will make that Apple will eliminate this problem in the next version of iOS. More report - greater chance.

  • IPhone 6 Battery Usage function not working

    Battery Usage feature continues to read; "Battery information will be available after using iPhone for a few minutes" even though I have now had the phone and used it for one week. Using iPhone 6, 64G, IOS 8.0.0.(no iOS updates have yet been applied) 
    A few days ago I attempted some suggestions posted by others. One of those was to let the battery drain to zero then fully charge. This had no affect on the Battery Usage feature. Another suggestion that i tried was to close all open apps on phone, then shut down phone and then turn back on. This did not resolve the Battery Usage issue either.
    Is apple aware of this issue? Any help would be appreciated.

  • Since I installed Lion on my macbook the LED light does not pulse when I close the screen - the sleep function does not work.

    Since I installed Lion on my macbook the LED light does not pulse when I close the screen - the sleep function does not work neither when chosen after pressing the button nor chosen in the apple menu..

  • Every time my MacBook Pro is put to sleep, it will not connect to the internet when reopened unless diagnostic assistant is performed. Ridiculous!

    Every time my MacBook Pro is put to sleep, it will not connect to the internet upon reopening unless I perform diagnostic assistant.

    Test after taking each of the following steps that you haven't already tried. Back up all data before making any changes.
    1. Make sure the network is on the preferred list by following these instructions. It's important to read the article carefully, as it's the starting point for any further efforts to solve the problem. If you skip any of the steps, the problem may not be solved. Make sure the box marked
    Remember networks this computer has joined
    is checked.
    2. Follow the instructions in this support article under the heading
    Symptom: After restarting or waking from sleep, my computer might not connect to the Internet
    3. Reset the PRAM.
    4. Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
    5. From the Location menu at the top of the Network preference pane, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.

    7. Repair permissions on the startup volume.
    8. Turn off Bluetooth and test.
    9. Reset the System Management Controller.
    10. Reinstall OS X.

    Hmm... I've had this macbook for a while now (?? a year maybe ??) and about 2 months ago I started having this exact issue, close lid to sleep returning it would not wake and a hard reset (hold power for 5+ seconds) is required.
    I too discovered such links as this and also the older (also unanswered):
    http://discussions.info.apple.com/message.jspa?messageID=8690782
    But as others have said there doesn't appear to be a solution?
    RESET THE SMC (http://support.apple.com/kb/HT3964) does appear to work, however the issue returns again after a few days or weeks... I cannot find anything that guarantees to return the issue it just starts happening again after a while.
    The battery appears to be in okay condition, although I think it might run down a little faster now days than when I first bought it, but I assume this is to be expected.
    I also had suffered from what sounds like an issue with wifi weirdness - signal would drop to 0% suddenly, no longer "see" the wifi hub that it has been using forever (although it still, randomly, sees other nearby hubs) for no apparent reason, and that kind of thing - all these times the only solutions that have worked have been to stuff around with the wifi hub turing off extas, flipping from "Auto" to a specific Number (1 to 13) and turning on (OR OFF!) Mixed B/G to just B OR G... very strange... and random.
    The only things I've changed recently are, upgraded to snow leopard (from leopard) and got an external display. But I cannot say if the incidents coincided or not, as I didn't realise the sleep/wake issue was an issue for a while, as the first few times I just thougth "Oh, something weirds happened... Reset..." and didnt' really think too much about it until it happened for the 3rd or 4th time and I could see there was a pattern...
    The external monitor via minidisplay port adaptor i got from teh apple store.
    I don't use it with the machine closed or external keyboard/mouse, although I've heard you can do this, I use the monitor as a secondary display when I'm at the desk, the rest of the time I just use it as I have always done.
    I would love to see a solution to this, I guess I could try warranty, but I dunno if the issue is warranty "level"...?
