LaCie power supply brick died

sorry, don't know where else to post this.
i have an external LaCie D2 optical drive and after about 5 years of (more or less) continuous operation, the power supply brick died. obviously no power to the drive and clicking noise from the brick.
i understand nothing lasts forever and already ordered a replacement.
i was just wondering if getting 5 years out of such brick is a decent lifespan.
thanks

mine died a month ago after just 30 months.
Seems they may be getting less reliable then.
Thankfull for the 3 year warranty as it was covered and they set me a replacement.
Was so worried it was the drive itself.

Wrong power supply brick provided with laptop, need replacement

I purchased a dv7-4060us laptop from Office Depot about a week ago. When unpacking, it was discovered that it contained a 65watt power brick. While using the laptop with it plugged in, a notification popped up saying the power supply was insufficient and would work, but would be slow to fully charge the battery. After googling a little, it was discovered that it should have contained a 90watt power brick. I tried swapping it at Office Depot to which they responded that they did not have one to give, and to call HP.
How can I get the proper power brick?
Thanks,
Scott

Might be less of a headache to return the unit to OD for a full refund, then shop it somewhere else.
If not,
This us a user to user forum, Contact HP directly, they will guide you on what to do next to get the correct adapter

Power supply retailers near Philadelphia? G5 won't turn on anymore.

When I went to bed last night, my Mac was on and running fine. This morning, it was off, and would not turn back on. When I press the power button, absolutely nothing happens. I plan to replace the battery first, as I have seen recommended. If that doesn't do the trick, I'd like to try replacing the power supply. Does anybody out there know of any retailers in the Philadelphia area from which I might be able to purchase the appropriate power supply? I'd hate to wait for it to arrive in the mail from California or other far-away places if I can get it locally.
Just to preempt two questions I know I might get, the machine is totally out of warranty. Every protection plan, etc. I had ran out not too long ago (of course). Also, I've checked the serial number of the machine, and it doesn't fall within the ranges of the machines that had power supply problems.

I just had my Powermac G5 die on me last night and found your post to be similar. I was wondering what you have done to remedy the situation. Was it the battery? I'm inclined to think that the power supply has died on mine. I appreciate any info that you could share. I, too, am uneligable for the replacement program. have you seen any FREE directions on how to replace the power suply yourself?
Many thanks,

Power supply from iMac through FireWire

Dear all,
The user's manual of my iMac G5 writes: "The FireWire port is designed to provide power for FireWire devices (up to a total of 8 Watts)".
How does this work? Can I operate my DV camera or external HD through it? What do I need to activate this service?
Lacmac

Laszlo-
The only products that I know of that tap into that power supply are flash memory card readers and (physically) small hard drives. You do not need to do anything to "activate" the service-it is just available at all times on a couple of the pins on the six conductor firewire connector.
Video cameras use the firewire port to transfer video information and control the camera functions. Video cameras use their own power supply brick or battery for juice. I do not think that the 4 pin cable that plugs into the video camera end has juice on it.
Peace-

Does Creative sell replacement power supply / ac adaptors for out of warrenty produc

The part I need is the external power supply / ac adaptor. It's rated 3.5 V at 5Am
ps.
I checked every other possibility in the setup of my system and came to the conclusion that the power supply has died. I confirmed this by using a OHM-Meter which showed no power flowing through the device.
The device has a model number on it
Model: UA-450
If anyone knows if/where I can get a replacement part.
I emailed Customer service but have yet to receive any reply.
Thanks in advance,
Steve

Thanks for your note.. I am still not getting any display or Target firewire startup after
several days of off and on attempts to try every variation of reset, pram/nvram reset et.al because i hoped to have one shot at re-booting it to avoid sending it out for repair with data on the hard drive.
I've tried with and w/o battery in... (fully charged). I'm able to get through the PMU using shift-fn-ctrl-power keyboard combo but on subsequent attempts to restart,
power button with T or even power button alone, there is no power-on at all but a few times I've been able to get the PMU reset and before I go to manually restart it, it restarts (chime) itself, however the only thing indicating it is on is that the caps lock key lights and i can hear (listening with my ear to the thing that it's "on..." yet the drive never gets spinning - If there's any other idea to trick this thing into a Target FW startup or other means of accessing the HD to remove certain data i'm still hoping to get this one fixed (esp. if it is only the cost of a Logic Board replacement.
What is really curious is that a few times it has gone to a PMU reset (with the single beep) even when i have just tried to startup with the power-button alone....and then, as i say, restarted (well, powered on..but nothing else...no display, no drive recognition presumably...)

Does the new Time Capsule still have the exploding power supply?

I've always liked the idea of TC, except I read how the design is so bad, with power supplies that explode, fans that simply do not turn on (what is the point to that?) and so have a VERY short lifespan.
Has Apple finally designed the TC so that it will last as long as any other hard drive? That would be nice. Then I would get one.

I doubt the word explode is correct.. overheated and caused the capacitors to die.
The design is fundamentally flawed. There is no way a running fan can draw in cool air so there is no point running it. The unit is sealed so when the power supply does die, it cannot be replaced.. although as a part it is probably $20 and would be around half an hour of techs time to replace if they were made available. But no.. it is a consumable. Someone has been having to many executive lunches to understand the cost is significant to the hoi polloi even if Apple Executives miss the point.
The newer ones are definitely cooler running.. but the same design flaw hasn't gone away.

Compaq CQ56-115DX Recalled Power Supply & Dead Motherboard

Hello,
We currently have a Compaq CQ56-115DX in our shop that we are diagnosing. Currently the computer turns on and sits at a black screen while the caps lock light blinks repeatedly. Upon further research we have found that it may have an issue with the bios. We are unable to get anywhere past that black screen so we cannot update the bios. We have tried pulling the CMOS battery and letting it sit for a bit in hopes that it might reset the bios. Unfortunately that didn't work. We believe the motherboard is bad. Looking at the support page for more resources I saw that there was a recall on the power supply for this machine. I went through the confirmation pages and the adapter is one of the affected models. Is there a possibility that the power supply could have caused the motherboard issue?
Thanks,
ST

It is actually a recall on the cord from the power supply brick to the wall plug, not the brick itself. If that goes bad you just get no power at all so the power supply is not the likely culprit. Is there any evidence of melting or arcing on the power supply at the place where the wall cord plugs into the brick? Does it put out power to specs? I would agree with your motherboard diagnosis, by the way.

Airport Extreme Power Supply Voltage?

We just moved and apparently packed our AEBS separately from the power supply. Does anyone know the voltage and output current (or power) from the power supply so that I might use an alternative until we find the original?
I hate to spend the $20 (and shipping) for a unit I'll find some days from now...
Thanks,

The Airport Extreme power supply brick output is rated at 5.1V DC, 2.4 A. The polarity of the plug's sleave is negative, the center terminal is positive.

Daqcard 6036e affected by laptop power supply?

Hello NI types;
I have a problem that seems pretty bizarre to me, so I thought I would share it with you to see if anyone has any suggestions.
I have a brand new Daqcard-6036E (pcmcia card), with shielded cable and the CB-68LPR terminal block, and I'm trying to use it with a Sony Vaio laptop (PCG-955A) with Windows XP professional. Labview 7, full installation with all the recommended drivers from the Labview 7 cdroms (didn't install anything from the 6036E cdrom, since I figured the stuff on the LV7 disc was probably more current anyway).
The card is recognized by MAX, Labview, etc. I can bring up the test panels no problem. I measure in differential mode, -10v to 10v range, I'm using the proper terminal pairs for the differential mode (aich0 + aich8 for diff1, etc). Problem is, regardless of what I put in for an input (I've used a little dc voltage supply, and bridging the terminals with a wire to enforce 0V) I get garbage not even resembling the proper input. It does random fluctuations all the way up to the input limits (-10/10 V). I measure with a meter and everything looks great at the terminals. I don't have any other terminal block connections (no connections from AIGND's, AO, timers, etc).
Here's the weirdness: the setup works just perfect... as long as I'm running the laptop off the battery and not using the power supply plugged into the wall. This was really, really annoying to try and find (pulling out the power supply to the laptop was the last thing I tried after fussing with it for a couple of hours). Battery only: reads correct voltages, nice and stable. Laptop power supply: reads completely incorrect fluctuating voltages.
I checked that I was trying to read differential mode (in MAX, and my labview stuff I've written), and I have no idea what to try next. I've used NI stuff for years (LV2,4,5, Nubus cards on macs, pci cards on pcs and macs) but I've never had an opportunity to use a pcmcia card before. I've never seen this behaviour on any other setup I've worked on.
I have a few suspicions: laptop power brick (which plugs in on the same side of the laptop as the pcmcia cage) isn't really nice 19.6 V dc @ 3A like the back of the brick says (have not verified this), maybe bizarre ground loop problems (I get this problem even with no external sources hooked to the CB-68LPR, just the differential inputs connected together on the channel). Maybe the power supply brick makes rf interference that annoys the card (I tried moving the brick farther away with no difference). Maybe Sony just doesn't like me.
As a dumb test, I ran the laptop's power brick plugged into a 120v inverter running off a 12V car battery (ie - 12Vdc -> 120Vac -> 19.6 V dc -> laptop) and that made no difference (still didn't wdfdfork). My other thought is to try and run the laptop directly off a regulated dc supply fed by a 24V battery setup, but that'll take me a little while to assemble to test.
Any thoughts on this? Sadly I do not have a second laptop to try this all in to see if that rectifies things. Has anyone else encountered this?
I hope I haven't left out a salient detail. If I forgot to mention something relevant please ask.
Best regards,
Steven Cogswell

Hello Ben and others;
Indeed, you hit the nail on the head, except it was the other way around. I hadn't taken notice of it before, but this laptop (which isn't mine) doesn't even have a 3-prong plug on the adapter in the first place, only 2-prong (the cord/brick have no facility for a 3rd either, and it's the original sony adapter). I ran a connection from the AIGND (AIGND/AOGND/DGND on this card are all the same point according to the manual) to the 120v ground (3rd prong) and sure enough, everything cleans up and voltages are correct again.
And a small note for those taking notes, although I said the laptop is a "PCG-955A" (that's what's on the bottom), it's actually a Vaio FX120 (written in tiny print on the screen bezel).
Thanks for all you

Steve

NC6320 Power Supply Pinouts required please

I have an NC6320 which the PSU has failed on. Whilst waiting for the new one to arrive I bought a Trust universal adaptor, the HP adaptor supplied with it has fallen apart and I am now stuck. I need to know, when looking into the HP plug the voltages as you look into the end,
i.e O o .
These represent the outer metal connection the inner metal connection and the pin. They appear to be separate once you cut open the adapter
I have a variable power supply and I have cut up the broken adaptor, which the connections have broken on so I cannot find out from that, has anyone any info on which is the +ve and the 0v?
If anyone can I help I would be most grateful
regards
Richard

Posting for others who also later find their way here for answers:
The power supply N193 for my Pavilion DV7 notebook uses the center "ID" Pin so that HP can control which power supplies are used on their products, only their own. I suppose there could be two reasons for this, one to make sure the proper power supply is used and second to keep competitors from selling us replacement power supplies but the former reason is probably the real one.
I've done a search on this subject because my power supply has been slowly becoming erratic and today finally failed. I cut the DC side of the cable off near the power supply and have tried to measure voltages coming from it, nothing, zero. There are three wires, the center "ID" wire needs a voltage there or the computer won't power on. Here's the info I found on another web site called fixya dot com which I used as a guide to allow me to use another manufacturers power supply with the old connector plug from the HP power supply which died. I simply put a 1/4 watt 47K ohm resistor between the center ID wire of the cable and the +19 VDC wire and insulated it from the ground wire using tape. After you do that you can just wire the plus and minus or ground wires of the new power supply to the DC power cable from the bad HP power supply together as normal. The +19V wire goes to the inner shell of the DC plug and its ground goes to the outer shell of the plug. I was able to get the replacement off the shelf power supply on a military base in Afghanistan, where I am at. I can't wait two weeks to get something in the mail, had to fix this myself.
I would have included the full URL to fixya.(com) but this web site won't allow us to put URL's so here's the info:
Here is a cut and paste of the text:
I found the solution - and implemented it, it works. The blue (ID) line needs to show 7.5v. The simple way to acheive this is to simply put a 47k resistor from the +19.5v line to the ID line. Apparently there is a pull down at the computer end that means it ends up at 7.5v.
I cut the cable about 6" from the old HP power supply. I then soldered a female power socket onto the loose cable and soldered the 47k resistor between the ID line and the +19.5 line. I then plugged this onto my two pin power supply and the plugged it into my computer. It works very nicely.
Not wishing to junk the HP power supply unecessarily - it was still producing the 19.5v - I then soldered a power plug onto that ignoring the ID line. That now works as well. It seems that the circuitry that provided the 7.5v ID voltage in the HP power supply became flakey. I could have just opened up the power supply (I have already done that) and disconnected the blue line from the circuit board and just tied it to the +ve line via the 47k resistor and then wrapped it with the usual insulating tape.

G4 Dead. Do I need a new power supply?

Recently I tried to start my G4 and nothing happened. NOTHING. The day before I had shut it down using "Shut Down" and it hadn't shown signs of anything being wrong. Yes, it is plugged in.
Does this mean my power supply suddenly died?

I have been messing with my old G4 silver, trying to make it work for the grandchildren. It used to work OK, but the clock had to be reset everytime. Then we didn't use it for about 6 months. Now: Yesterday, I plugged it in and pushed the power button. After some normal-looking gyrations, the screen turned to a black pattern with the message, "You need to restart," which of course did not work. There also was some Chinese (I think) on the screen.
Replaced the battery with one from a friend's computer. Reset the PRAM. Voila, it booted and worked well -- for about 5 minutes. Went black. Would not turn back on.
Took the original battery to the neighborhood Apple shop. It checks out fine.
I put it back in, this time accidentally breaking one of the little plastic side holders. Having now read about the PMU here, I pressed that.
Voila. It booted up, even displaying the correct day and time, and finding the Airport connection. I deleted a few files and was just feeling really good when it went black again. Tried a different outlet. Nothing.
So, is there anything else to try? Is there any hope? I hear power supplies cost $100 or so and must be special ordered (therefore, kids will be home before the computer gets fixed).
I always get the most useful advice in these forums. Hope you can help me this time, too.

Dead Power Supply and LaCie Portable HD?

Here's my problem:
I coordinate a lab that has 8 400-MHz G4's. Four of the computers have just died over the past few months; no power at all when trying to start them.
I've already tried changing batteries and pressing the PRAM button, but that hasn't help. So it seems that there may be a problem with the power supply dying.
But here's the catch: It seems that the computers lose power when I connect a LaCie 80 GB portable Firewire hard drive to them. I was running one of the G4's today when said portable hard drive attached. I turned the computer off, then tried to start it up again. No power!
I know this has to be more than a coincidence, since it has happened once before. And now I'm thinking that is probably why the other computers died too.
Has anyone else had this problem occur? Or is this just my imagination?

Is the LaCie drive able to work with any computer for a sufficient period of time?
It sounds like there may be an electrical problem with the external drive that is causing some damage when plugging it into a computer's firewire port.

Lacie 200 GB FW400 Power Supply

I was doing some negative scanning the other day using my Nikon Super Coolscan 9000 and accidentally turned on my one of my Lacie drives at the time, which the Nikon scanner doesn't like. Every time it happens, the scanner stops in its tracks.
Anyways, this time, I noticed that the Lacie drive didn't power up all the way and just kind of got stuck and stuttered on the power up. I shut it down using the blue button on the front and kept on scanning, figuring a reboot when I was done would fix all, but it didn't.
The drive kept refusing to start up, even after I changed firewire cables and ports. I had given up when I got one last idea... I took the power supply from another of my Lacie drives and hooked it up to the drive in question and it worked. I took the power supply from the drive in question and hooked it up to a drive I knew to be good and the drive wouldn't power on, repeating the behavior of the previous drive.
So my question... is there anywhere I can get a replacement power supply for my Lacie drive? If anyone is wondering, yes, the drive failed once before - it's four years old - but Data Rescue II and Disk Utility resurrected everything that was on it.

Hi willscarlett-
If the drive is still under warranty LaCie will replace the power supply at no charge.
You can also order the power supply directly from LaCie for around $20. I use several LaCie drives, have been burned by a bad power supply or two, and now keep an extra one around just in case.

LaCie DVD-burner and iBook power supply problem

Hello guys!
I bought recently external LaCie DVD burner (USB). I experienced problem connecting it to iBook. It suppose to be possible to be powered up from USB but only possible way to power up burner only via external power supply. Is there is any possibility to adjust power in iBook so burner will work. I'v checked possibility to use it only powered form USB on MacBook of my friend - it works smooth only from single USB...
Thanks for any suggestions,
Ivan

320GB Hard drive power supply died - where to find replacement?

Hi,
The power supply for my external 320Gb hard drive (PX1223E-1G32) which I bought about a year ago has died. I am a bit annoyed as the drive has hardly been used and only just come out of storage after a house move!
Can anyone help track down a replacement in the UK? It is branded Dura Micro Inc AC Adapter 100-240V 1.2A +12V 1.2A +5V 2A and the DC power lead looks like a 4 pin 'DIN' type connector.
Does anyone have a contact email address for Customer service/retruns UK as it may be possible to replace it under warranty.
Thanks in advance,
Mark

Hi,
Thnaks for the reply. Yes - the dealer is the obvious first stop but I am not sure if the warranty is still valid or not as I am yet to find the invoice! I was just wondering if there was a cheap source of power supplies if needed as so far I have only be able to find very expensive suppliers. In fact it may well be cheaper for me to buy a new drive enclosure and to transfer the drive over than to buy an actual new power supply.
Thanks,
mark
