WRT150N power supply humming?

Hi,
I have been having lots of issues ever since I upgraded my firmware.  I have been changing the wireless channel on a daily basis trying to find the best one with the least intereference.  Then last night when my router locked up as I was power cycling it to bring it back I heard my power supply making a buzzing sound while plugged into the wall.  I unplugged it and left it that way all night and when I plugged in this morning no buzzing sound.  I am wondering if maybe my power supply is faulty and causing my router to lock up.  When it kicks me off today I will check again.  Anyone else have this problem?

Power off the AirPort Extreme for a few minutes and start it back up to see if a simple reset will get things going again. If not, replace the power supply.

  • Power Supply Hum

    I have a new iMac G5 that has a high pitched-medium volume hum (loud enough to hear from another room). The Apple servicer replaced the power supply and the hum still occurs.
    The problem seems to be that the hum only happens in my house, not in the shop when I was there for the re-test.
    I tried plugging the mac into different parts of the house, with and without the surge strip, with and without accessories (printer, etc.).
    Any ideas about how to filter, or solve?

    Then there may be some electrical issue in your home which needs looking at by an electrician. The fact it is unique to your home and not your computer, seems to say the computer is drawing just enough power that your home electricity is doing odd things whenever your computer is on. I had a hum come from several of my outlets, and learned that because my home wiring was done by the previous owner and not an electrician, some of the wiring was beginning to have some of its own arcing. Sometimes just leaving a lamp plugged in and not turned on would cause the hum to start.

  • Mac Pro 8-core Power Supply Making Humming Noise That Comes And Goes

    This is in reference to a Mac Pro 3,1 8-core purchased around Feb 2008.
    Lately, I've noticed a strange noise coming from my power supply that sounds like the noise a refrigerator radiator makes. It's a humming noise that rapidly comes and goes, constantly.
    The power supply fan speed is running at 599rpm
    I'm not sure if the problem could've been caused by adding additional ram (12GB, OWC) or an additional HDD (3rd HDD, WD), but I didn't really notice the noise until after adding these components.
    What could be the cause of this problem? What are my repair options if necessary (without Apple Care)?
    Thanks in advance.

    I know for a fact it is not any of my hard drives because the noise is becoming more frequent no matter what hard drive I use, I actually have a 1.5tb, a 1tb, two 500gb and two 320gb drives, I have set an appointment to take my system in and have it tested, it is starting to crash 5-6 times a day. I can not get a lot of work done with this annoying spinning noise and the shutting down. Thank god for my Apple care, and I have visited various forums that lead me to believe its the power supply going out, with the symptoms it is having. This article and others like it explain what to look for when a power supply is going bad.

  • MBP ac hum power supply

    All was perfect Monday. But today, while finalizing an audio-visual setup, I was getting an AC hum/noise from my MBP's 85W MagSafe power supply/charger.
    I could swear that ALL is the same from Monday's setup. I thought it would go away after the battery pack was fully-charged. Nope - noise still there.
    Is it worth me trying a backup power supply - or should I just un-plug from AC for our one-hour event?

    P.S. - It is a cool event - students will be talking to an astronaut in the morning ... an astronaut who is aboard the International Space Station!

    Humming noise from a power supply can come from a loose winding on one of the components. From reading up, I glanced that this doesn't influence the working. Could have happened if you dropped the power supply. They stick some white goo in places, perhaps that got loose.

  • Humming power supply?

    Apart fro the slight fan whirr...which appears to be normal, I get this slight deep humming noise...possibly from the power supply or hard drive. When I lift the iMac up, it is gone. I have a piece of foam on my wooden desk, which reduces the humming a bit. In the past the humming went away once the computer had warmed up properly.
    Do you experience the same?

    "All this ramping up and down of the cpu temp and fan speeds, when the unit goes to sleep, can't be doing it any good."
    The CPU temp & fan speed varies with processing load under normal usage, even with CPU prefs set to a fixed performance level. When the machine is unattended but not asleep, various background processes will still run (maintenence scripts, Bonjour & USB 'discovery' probes, etc.), so sleeping the computer may actually reduce the net thermal cycling.
    It also will reduce physical wear & tear on moving parts (fans, hard drives) & the time electrical parts are exposed to elevated temperatures, which may extend their lives. Balancing that, the "ramps" are obviously more extreme when going from sleep to wake states.
    Overall, I think the best compromise is to set sleep time to an hour or so, or whatever setting for your usage pattern that avoids sleep kicking in frequently throughout the day but does allow overnight sleep.

  • Humming sound coming from power supply after new battery update?!

    i've heard of MB whining.. but not power supplies...
    it's new with the latest battery update.
    it stops when i touch the power supply.
    it also stops when the processors rev up.
    is this normal??
    it's annoying as ****, and it never used to do it.
    any help will do.

    Hi, Dan:
    I don't have your model PC, so here are some generic instructions.
    Turn on the PC and at the beginning of the HP welcome screen, tap the F10 key to gain access to the BIOS.
    There should be a menu to Save Defaults and Exit, when you go to exit the BIOS.
    That is all there is to it.
    I can't find your model number to give you the link to the audio driver from the support and driver page.
    If you have the IDT audio chip, below is the latest driver for it.
    Or let me know what model audio device you have and I'll see what I can find if it is not the IDT audio.

  • Power supply vs. logic board?  turns off in sleep mode.

    My imac g5 (2004 - 1st generation?) is either turning completely off or going into some un-wake-up-able mode after it's put to sleep. (I have to switch off/on the power strip and turn the computer on all over again.) And sometimes if it's sleeping (power light pulsing on front) it may or may not wake from sleep by pushing the power button. Often touching a key in that circumstance will cause it to crash, so I've quit using that altogether as a method of waking it up. I've reset the SMU a number of times throughout the past few months and it has not cleared up this problem.
    Last night after I put it to sleep it switched in to the un-wake-up-able mode. I could still hear something running (not a fan, just an electrical hum) where it seems like it's crashed and can't shut itself off. I had to turn off the power and try to turn the computer back on. It wouldn't respond the first couple times. Then the power light glowed for a while but it still didn't turn on completely. After a few more minutes I tried again. Maybe I held the power button for too long, but I heard a long single beep, the fans whirred, and then everything started up as usual.
    I've read a number of threads seemingly related to these issues, but am now not clear about whether this is a power supply issue or a logic board issue. I have yet to open the back and check for bulging capacitors. Just thought I'd ask here first.

    I am having a very close issue too (posted also in a more recent thread about power button not functioning). My old iMac G5 20 inches got a power supply that went bad two years ago. I had it replaced and all went fine until two weeks ago.
    My wife was using it, while I was away: machine shut down with a 'pop!' sound.
    She tried to start it up again, but after pressing the button a couple of times - the last one longer - she had a long strong peep. The machine went on for a while and then off again. Scared, she left it off.
    After checking, no reported issue seems to fit to the problems shown: power supply is working; logic board too. The machine is working fine, but on sleep, it dies out. While doing tasks, at undetermined times, it shuts down with a 'pop!'. Sometimes you can restart it immediately. Sometimes you can't and have to wait one or more hours. No evidently bad caps on board, led check returns 1 (no 2 flashing or attempting to turn on) with dead computer, otherwise all working fine. Hardware test also passed. Console messages have nothing relevant or clearly understandable to offer.
    Still can't figure out a solution. Many user are pretty fast in suggesting to bringing the machine to Apple. Unfortunately not all around the world we have/need cars. And getting the 20 kg of iMac by feet/metro to the shop it ain't such a nice walk. When I fried the power supply, there was no sufficiently large box on sale to pack the computer and have it send to the shop. I had to wait for the technician - on a convenient day - do drop by and take it (and he knew he was going to repair it)!
    Will post, if I have further developments.

  • UPS Causing Disturbance to Mac Pro Power Supply

    I have been doing a lot of work on upgrading two Mac Pro's over the last few days. I have one attached to an APC UPS 1300VA 780W rated. Normally this Mac Pro is under my desk, so I do not here it. During the process of one of the upgrades I had the Mac Pro sitting right in front of me on my desk. As soon as I powered it up, I could hear this disturbing "hum" or "buzz" coming from the power supply of the Mac Pro. However the Mac Pro seemed to operate fine.
    I decided to unplug the Mac Pro from the APC UPS and into a regular Tripp-Lite wall surege protector with no UPS. The noise was significantly reduced. Therefore my question to you is:
    1. Do you think the fact that the APC is creating the problem or introducing a different signal (maybe not true Sine Wave) than what is required by the Mac Pro?
    2. For those that have a newer Nehalem Mac Pro and they have access to the back, how would you rate the "hum"? Is it what you would expect? Now that I have it off the APC UPS, it seems more normal (it is audible, but only with my ear close to it).
    3. How well are the power supply units in the Mac Pro designed? Enough to handle immediate loss of power? What about cleaning the power coming in? Sometime the voltage drop across my AC outlet is 110V to 120 V.
    Mike

    RS? XS? something other than those? The linked discussion OP had an XS and went to SMART unit. Before I bought CyberPower to replace one of my two 1500VAs (one XS and other RS) I decided to ditch APC this go around. And, glad I did. Quiet, green, stand-by mode.
    The 2008 had bad inrush current, and ever since the G5 Quad with 1kw PSU people have been looking for the best UPS.
    One article talked about PSU efficiency, and apparantly Apple's didn't match the 85+.

  • 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.

  • G5 iMac Will Not Turn On - Power Supply Diagnosis?

    My A1145 20" iSight PPC G5 iMac will not turn on - it doesn't respond to the power button. It had been shut down for a few days, I turned on the power and it booted up as normal, the desktop appeared and I was about to open the web browser when it suddenly went dead; the screen immediately turned off with no warning or noise. There is no fan or disk noise coming from it when the power lead is plugged in, just a very, very faint electronic hum from inside.
    From reading various webpages, it seems possible that the power supply could have failed. Is there a simple way that I can diagnose this before deciding whether to attempt to replace it myself or not? I understand that there should be some diagnostic LEDs which could help identify a problem - I've removed the surround from the iMac and peeled back the black EMI film below the display but I'm not sure for what or where I should be looking (they seem to be easier to find on the 17" models).
    Whilst I know a repair might not be cost-effective on such an old machine, I have 220GB of photographs, documents and music on it - none of which is backed-up - so I am very keen to get it working and backed-up as soon as possible.
    Could anyone suggest how to diagnose the problem?

    Hi there:
    My experience with Macintosh computers has not included the G5 iMac even though I almost got one to replace a failed-under-AppleCare iMac G4 17" 1.25GHz after three/four major failures and no local support.
    ...So, I think you may be able to pull the hard disk drive out of that computer and see if an external enclosure could allow you access those files IF the drive spins up at all. Sometimes odd things happen, and the G5 iMac had some history of capacitor and other failures that could be a problem. I see there are a few free information guides here that may be helpful: http://www.ifixit.com/Device/iMac_G5
    If the battery on the logic board was dead, but the computer kept in running condition by leaving it plugged in, once the computer was left unplugged for a time then the device may fail to start. There is a way to reset the power management chip (different names for same idea as technology moved forward) and that could help in the process of troubleshooting most power related issues in the PPC Macs of later G3/G4/G5 design.
    There are troubleshooting items of interest in here http://www.apple.com/support/imac/g5/ ie: what to do when your computer won't turn on...
    Sorry to not be of direct help in this matter.
    Good luck & happy computing!

  • Anyone having Power Supply Failures with 4305's

    For some reason over the last 6-8 weeks I am getting multiple power failures on my 4305DMPs, replacing the power supply/wall plug brings everything right back but I'm wondering if there is a bigger problem.
    All DMP's are connected to APC power bars with Surge Protection, and the LCD Screen continues to work fine. The DMP will just quickly flicker both Red and Green Lights, and remain unresponsive. We have tried cleaning teh contacts on the power supply but have had no luck.
    I have had to swap 10-12 of them now, these have been working with no issues in the field for over 3 years.
    I guess I am just wondering if anyone else has had this problem, a search on here didn't reveal anything.
    Thanks,
    Jh

    I haven't heard anything about this on the 4305, but just pointing out that this is a 2-year old post.
    We're using some Linksys POE -> 5V splitters and they've been humming away for years. I listen to feedback about reliability, but it would be helpful if a specific part # / manufacturer on the brick were identified along with any complaints about it.
    As far as replacements, be sure to use the right specifications, other DMPs operate off of 12VDC but the 4305 uses a 5-volt adapter.
    Input voltage: 5V
    Input current: 3 ADC
    Power consumption: Peak: 12W; average: 5W

  • C3750X get power supply errors

    Hi, I got a problem with some phones connected to a C3750X-48PS. Phones are Polycom SoundPoint 560. Ports most critical: gig 1/0/9 & 1/0/31.
    Actually, the C3750X belongs to a stack, with the IOS: 12.2(55)SE3.  The environment conditions: power supply working ok, temperature level: ok. (show env all). Physically the LEDs are in green, and the room does not have temperature issues.
    Also, the phones present a humming noise (high pitch). The noise keeps happening even if the phones are plugged in other ports of a stack. It was attempted to connect the phones directly to the stack ports instead of the ports in the cubicules, and the issue keeps happening.
    The Stack presents also sudden fan to spin up / spin down for a couple of minutes, and within a couple of minutes from working on and off.
    Customer has another facility with the same switches but with IOS12.2(55)SE1, in there the same phones were tested and they are working fine.
    A reboot was performed, but now the C3750X show these messages:
    %ILPOWER-3-CONTROLLER_PORT_ERR: Controller port error, Interface Gi1/0/9: Power Controller reports power Tstart error detected
    %ILPOWER-3-CONTROLLER_PORT_ERR: Controller port error, Interface Gi1/0/31: Power Controller reports power Tstart error detected
    Thanks!

    I've found it!  In case anyone is wondering, a lot of server information is available by querying with the iLO xml tag "GET_EMBEDDED_HEALTH".
    This returns, buried way down in the results, information about power supplies (section POWER_SUPPLIES).
    While there doesn't seem to ask for just information on the power supplies, this works!

  • HD power supply under Optical disk.

    Hi,
    I have Sonnet E4i, a Pci-e card that has 4 internal esata ports.
    I know there is the Maxupgrade way to fit more drives under the optical bay, but I'm wondering if I can accomplish putting more drives there using the card I have. I think I can but I'm wondering about the power supply for the drives. I have a 4 disk connector that came with a G5 Jive I bought. Could I use that to connect to the one free set of HD cables under the optical tray and thread my esata cables from the card to my drives?
    Thanks much for any info.

    If storage is your cup of tea, here's another sweetener:
    http://www.xbitlabs.com/articles/storage/
    $200 use to be sweet spot I thought. When the 100MB drive gained popularity, they went from $1K to $300 rather quickly at one point.... for real? a scam? and snapped up like crazy. $395 for a number of drives (100/120/160) for awhile. I 'splurged' on a couple 9 and 18GB, and I just did not like the humming pitch of 10K Cheetah - at all! 10K Raptor saved me from some more 36/74GB SCSI drives. I got "paid" in Raptors, but they were really 1.0 anyway.
    My project is to build a nice system, and I've got bookmarks, reviews on cases, coolers, what to know about PSU, all in spreadsheets, "wish lists" and more. Unfortunately and happily, I'll wait for more R&D results.
    I lost some hearing on the firing range and then during fire fights, but you needed ear plugs (and wool socks) in glass cage and those old timer systems. If someone said I'd have 8GB RAM and 10TB of storage, I"d think HAL9000 got to them!
    A case of Ensure is more my cup of tea today I'm afraid!

  • MSI Vox Power Supply...awesome!! PLEASE READ

    Hey,
    Welll, alll I can say is anyone that's been having issues with their Vox unit....get the power supply!!!
    I had sound, picture, record issue's!! Gone. Plugged in the power supply, no humming sound in the background, picture quality has improved 100%, over and above the improved picture quality of new Beta MSI PVS 3 by Stu. I wasn't able to record a program, once I setup for the recording of a program and hit the button close, the MSI PVS crashed...no more!! I say the power supply should have initially been sold with the unit, but as MSI put it. " the Vox unit was sold to be a portable device and with the power supply it is no longer portable". My answer was, "if the unit will perform the way it was manufactured to perform only with the power supply, package it with the Vox. If those in certain parts of the world do not need to use it they can simply put it aside".
    Anyway, that's my 2 cent's of a possible solution to a lot ot the problems posted here.
    Hope this help's a few people out!
    Cheers!! 

    I received it from MSI. I had sent and e-mail to sales which had been forwareded to tech support. They contacted me for address and payment info and I had it 8 days later. They sell it for $10 US and the shipping was $4.
    Stu's right though. The only thing for me is my retailer wasn't able to get it for me so I contacted MSI.
    Hope this helps.
    Cheers

  • An ATX P4 power supply and a MSI-6119 motherboard. Does it work?

    I am reparing my computer. (Power supply broke down)
    I found a cheap ATX 350W P4 power supply.
    It is intended for P4 motherboards, and has the same connectors as my old PSU, except one more: the ATX 12V connector (4 pin , 2 yellow 12V and 2 black earth), that you normally have to plug in a 4 PIN connector called JPW1.
    On a PII/III board such as the MSI-6119, there is no JPW1.
    Apparently the PSU doesn't start up if the ATX12V connector iis not plugged in.
    How can I make it work?

    Thanks for the manual.
    No beep when booting without RAM. No sound at all. power supply does not start.
    I did the following:
    1. Disconnect PSU from everything - do not plug ATX connector, but short circuit pin 14 (green) and 15 (black) of the 20 pin ATX connector - put in external power cable. The PSU starts humming.
    Apparently, when pin 14C is pulled low, the ATX PSU jumpstarts. ( see http://www.duxcw.com/faq/ps/ps4.htm ).
    2. disconnect all drives ( HDD, CD, FDD ) (power supply and ATA66 cable) - plug 20 pin ATX connector in motherboard - connect power cable -  no boot;
    CONCLUSION 1: Pin 14 is not pulled low by the circuits of the motherboard, which it should. why?
    3. connect all drives ( HDD, CD, FDD )  with power supply cables to PSU and ATA66 cable to motherboard.
    PSU not connected to motherbord
    short circuit green and 15 of the 20 pin ATX connector.
    Power supply starts, HDD and CD however not ( FDD starts ).
    CONCLUSION 2: connection of ATA66 cable disables power supply to HDD and CD/RW
    4. connect only power supply cables to HDD/CD /FDD and not the ATA66 cables.
    No connection of PSU with mothetboard
    short circuit green and black of the ATX connector. ( So Motherboard not implicated )
     - Power supply starts, HDD / CD and FDD start also.
    CONCLUSION 3: my HDD etc and internal power cables are OK.
    And I am no step further.
