New power supply and sleep light question

I just got my iMac back with a new power supply and logic board installed under the Apple repair extension program. I had diagnosed the problem using the Apple troubleshooting assistant online. When I did this I also reset the SMU (system management unit) per the instructions with the troubleshooting assistant.
My computer is now working correctly but when I run Software Update I am prompted to install the iMac G5 Sleep Light Update version 1.0. I had previously installed version 2.0.0 back in July/05. I don't have the ambient light sensor iMac. I am a little nervous about installing this version or reinstalling the version I alreay have in my utilities. I realize this is a firmware update and cannot be reversed.
Anyone else experience this with 2 different versions of the Sleep Light Update, I don't seem to be able to find any info on the Apple site.
Thanks for any info
Scott

"reinstalling the version I alreay have in my utilities"
Please correct me if I'm wrong, but if you have it in your utilities folder, I believe that means that the installer folder has been downloaded, but the install was not done. I am thinking that once installed, it disappears from the Utilities folder.
I see no reason why you would need to do that firmware update if you don't want it. In the future, if you or someone else wants to do the update, it'll still be available on the Apple website.

IMac G5 ALS not booting with new power supply and perfect capacitors

Hey guys. Just got this beauty yesterday for cheap. Came with the box, 2 of 4 Styrofoam inserts, the manual, the power cord, and the keyboard.
I was told it has a brand new power supply. When I plug it in, LED #1 on the motherboard comes to life. pressing the power button does nothing. I have tried everything: blowing out any dust, reseating all connectors, booting without RAM, adding a hard drive (did not have one), removing the optical drive, modem, and BT/ap card. The only sign of life is when I press the internal power button, and the light flickers. This is promising.
I did notice when it is plugged in, there is a high pitched whine coming from where the LED is. I hope this is not causing the problem.
All capacitors are perfect, and not burst or leaking. I had a 1.25ghz eMac with bad caps, so I know what they look like.
I removed the motherboard, and there is no sign of any fried component on either side. It looks like a brand new machine basically.
I was thinking of just getting another good logic board for it, as they are cheap, or ask a friend to recap the board anyway.
Anyone here know what could be wrong with it? I hope I did not just waste money on this. It was relitively cheap though.

Hey Lam,
The only sign of life is when I press the internal power button, and the light flickers. This is promising.
I did notice when it is plugged in, there is a high pitched whine coming from where the LED is. I hope this is not causing the problem.
I'm with Miriam on this one. That "new" supply sounds bad. Look very carefully inside the power supply (through the little perforations in the case) I'll bet you see caps w/ the same domed tops like you've seen before. That whine is also a symptom of a bad PSU. It's not even strong enough to power the soft start.
I've seen 2 20" and 3 17"ers recently. Replaced caps on 3 of the PSUs and got one to work on a 17" that belonged to a teacher so that went back. Swapped the working PSU from one of the 20s w/ a bad GPU into the one w/ a bad PSU. It's working but in a place where I can keep an eye on it since I don't trust it since the caps don't look good.
I've done this hack:
http://gallery.me.com/iamkimc#100033&view=grid&bgcolor=black&sel=12
and can get all the iMacs to work that way. Advantage - cheap, totals 1/3 or the replacement Apple part (used). Con - boxes outside the nice iMac case.
The auto laptop supply loads the Sparkle down too much for the 20" however. I'm working on finding an auto supply that saps less Amps or a simple voltage doubler for the 12V supply to solve that problem.
The ATX hack is pretty simple and only requires switching two 12V leads. Oddly one of the early versions of the 17"ers ran fine without the 20V inverter power. Go figure.

New power supply - constant sleeping

Hello all
Power supply recently let go so had a new unit fitted and the the machine returned as working.
Unfortunately machine constantly sleeps. I have chucked out PLIST and tried to run from disc warrior (the machine just shuts down befor full load up from DW).
Any clues before I throw it back in through the shop window?
S.

Hi Mack
Thanks for stopping my lonely feeling!
Got to the second Panther install disk and the sleeping sickness started again (thankfully a reasonable backup discipline and the ability to run the machine for a few minutes before I wiped the old startup disc prevented any disasters).
So it is back to the Alfreton (Derbyshire, UK) Mac hospital and more expense I suspect for my MDD.
Anyone know how much a logic board is in UK beer vouchers?
Depressed....

Cisco power supply and APC UPS question

Good afternoon, I am running a 4507 with the Power Supples PWR-C45-2800ACV
http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps4324/product_data_sheet09186a00801f3dd9.html
Can I plug this power supply into this UPS unit?
http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=SMX3000RMLV2UNC&tab=models

Jason:
My guess is that 2800w power supply is looking for two legs of AC in to make the DC stable on the switch.   I've installed a lot of 45XXx over the years but I never have more than 100 ports of active POE on them as most buildings have lots of computers and printers and a few VOIP phones and access points.
Now, those power supplies are pretty fault tolerent and well built. They can take (probably) swing voltage from 40-240V and 50-60Hz.    You can wire up the L6-30 into the TWLK cable and only have 20A of 120V on one leg from the output of your UPS.     You just have a single 30A hot, neutral and ground and a dead leg for hot into the power supply.   You use half the power supply.
The capacitors on the power supply will just have to absorb that and deal with it.   That's their job. Short term batteries.
One thing you need to realize is that you don't have to have two full-capacity 2800w circuits for the switch.   The 2800 is a reference number and that's based on a lot of inneffiencies in the entire system.
You've got at max a 2800w load and either 1 or two power supplies will feed it.    Two power supplies will be slightly less efficient than one but you're not pulling 5600w.
If you could, answer the questions above on the number of POE devices you've got and we can work a solution to solve the power to the switch and to your nodes.
You've got a lot of expensive, quality gear and the best solution isn't always to double up and re-buy what you've got.
I am going to recommend a metered PDU so that you can watch the amperage as when you approach the limit of what your wires can haul, you need to pay attention to the national electric code.
If you can PM me, do.

Power Supply and Graphics Card Question for HP Pavilion a6432p

Hello!
I have the HP Pavilion a6342p, and I'm wanting to install an NVIDIA Graphics Card either 512MB or 1GB. However, I'm not sure what is the power supply to this model (most graphics cards are saying 300-350W supply required).
Can anyone tell me what is the power supply to this model, and what would be a good graphics card model to look at to upgrade my graphics card to with this model? I believe the expansion slots are PCI-Express, but I'm not sure on the power supply so I can get the right graphics card.
Thanks!
Nathan

No the 9100 is not just an integrated video chipset and is available in both AGP & PCI form.
The Antec is a good PSU but I would recommend getting something better such as the OCZ or Enermax as they have a higher +12v rail amp.

New power supply and graphic card for Compaq CQ3232L

Hi all,
I am using Compaq CQ3232L and would like to upgrade the graphic card with one of the HD 5770, Sapphire HD 5770 Vapor-X 1Gb 128Bit DDR5 to be exact.
My current power supply (Bestec Model ATX01...) specs are:
+12V/11A, peak 13A
+5V/10A, +3.3V/10A,
-12V/0.3A, 180W according the manual.
I've been looking a replacement for the power supply but not sure which one will fit the case? And how much power will be need to run the Sapphire card and future upgrade (Blu-Ray drive and another HDD)?
Regards,
Eko

WSH, besides measuring the PSU, you should assure that there is sufficient space for the video card. Open the case. Measure from the edge of the case to the opposite side of the motherboard where the PCIE slot is located. This is the approximate length of the card that will fit.
Also, I like OCZ and Corsair PSU's. They are both enthusiast/gamer manufacturers. Their products will provide clean, stable power for your system.

MDD power supply and fan upgrade kit question.

Hello, Its been a few years since I posted anything here and I'm getting ready to (possibly) trade in my mirror drive door 1GHZ dual processor machine on one of the current imac-s.
I'm not real hopeful that putting much work into my current machine is worth it. Here's why:
1) crazy levels of noise - I wear woodworking hearing protectors when I surf the web. Listening to music on itunes is fine so long as you like a background of low level blow dryer noise!
2) I'm still running OSX version 10.2.8, I have been too cheap to buy the latest OS. I'm tempted to go out and spend the $119 on 10.5 but I only have the original 256mb of ram installed and since the min requirement of ram is 512, I know I'll need to spend an extra ~50$ on a 512mb PC2700 ram chip. My price tag to do a minimal update is rising...
3) I would love to neutralize the noise and install the Apple provided MDD power supply and fan retrofit kit that they sent me at no charge several years ago while I was still under warranty. But I never did because the tech at my local (Dayton Ohio) reseller told me that the kit only addressed high noise levels when rebooting in OS9. So I never bothered. Looking on ebay, I see where power supplies for G4's could fetch 75 or 100$ or so.
In summary, here are my questions.
1) Has anything come along recently to tame MDD G4 fan noise that is easy to install, cost-effective and most of all, something that actually works to decrease the noise?
2) To get the quietest, quickest performance with the current OS 10.5 should I cut my losses now and trade (or sell on ebay) my MDD, sell the new power supply and just purchase a new machine with the OS already installed?
Thanks a bunch in advance for any assistance...
from Bill.

Bill,
Carl has some pretty good points that I'd agree with - trying the replacement PSU and fans should quiet it down somewhat and replacing the stock main fan with a newer, quieter unit will also help. But I'm going to disagree with him on running Leopard on the G4's with a few reservations.
As you might notice from my profile, I'm running Leopard on my dual-867 MDD and find the performance acceptable; perhaps a little slower than Tiger in some respects but it does run well enough within the limitations of the G4's capabilities. The reservation I have about recommending Leopard on a G4 is the graphics card - without Core Image support (which you won't have unless you upgrade the video card) Leopard is going to tax the CPU more and may bog down in some tasks like Quick Look and Cover Flow.
In the end, whether to continue upgrading the G4 is a matter of use and economics. Tiger would be a fine upgrade with minimal cost and squeeze a few more years out of your G4 if you're not requiring software that needs an Intel CPU (like certain iLife '08 apps).

Problem with NEW H520 when installed new power supply & graphic card. Please help!

My H520 was working perfectly and was running FAST..especially when rebooting. ( It was AWESOME! )Then I installed a new power supply (Coolmax 400w) and a new graphic card (Sapphire Radeon HD6450) and then everything changed. Now my computer is booting very SLOWLY and all the programs are taking a long time to load too. I was getting a black screen for almost a full 2 minutes before the windows 8.0 screen would finally load up and then it hangs there for a few seconds and finally goes to the start screen in windows. But BEFORE I installed this new hardware, when I would reboot, I would see the Lenovo splash screen come up for a few short seconds and then it instantly went to the windows welcome screen. And even then I would barely have enough time to see the welcome screen before it instantly loaded into the windows start screen. Everything would load up fast on the desktop too and we'd be good to go. It all took about 30 SECONDS.
But now? It takes MINUTES to get everything going. After it FINALLY loads up (it takes almost 2 full minutes now!), everything hangs up. When you first click on the desktop, it takes a few seconds for all of the icons to pop up. Before I loaded the new hardware, everything loaded up instantly. I didn't even see the icons load because they were already there. But now I have to wait for them to load up before I can even see them. And it's like that with every program and web browser I try to use now. Everything hangs up at first and then finally loads. The programs work but they are sluggish.
So I uninstalled the new power supply and put back in the original 280w power supply and I took out the graphic card but it did no change. The machine is STILL running slow on everything it does and booting very slowly.
I have seen this problem mentioned elsewhere about Lenovo computers but there is never a solution. Please help! It took me a long time to save up for this computer and I have been babying it ever since. I will never be able to afford a new one or pay for tech repair. I need to fix this! I was so thrilled with this computer before the hardware upgrade. This is devastating to me that it is working so poorly now when all I was trying to do was upgrade it a little bit.    Now it's performing horribly and it's only 6 months old.
I ran a four hour test on the hard drive and it is fine. I ran all the system clean ups, optimizations, registry cleanups, windows disk cleaner, defragger and virus scans. Nothing is showing up as not working but there is CLEARLY a problem. It was never this slow.   And why is it STILL acting this slow even after I uninstalled all of the new hardware that made it start acting this way and went back to the original setup?
I'm trying to run a memory test on it now but the BIOS will NOT allow me to select another drive to boot from so I can't boot from the flash drive or CD drive to run the memory test. I have NO IDEA what to do next and I am starting to pull my hair out in frustration.
Please, is there anything that can be done to make it better again?
Any help would be HUGELY appreciated. Thank you!
Sincerely,
Jennifer

I totally give up!! I restored everything to the ORIGINAL state with drivers AND hardware and STILL everything is not working properly like it was BEFORE the upgrade.
So this has been the WORST experience with Tech support EVER!! I have spent DAYS on the phone for HOURS with these technicians and nobody seems to know what they are doing. They put me on hold every 10 minutes and are gone for 10 to 15 minutes and when they come back, they seem all set on a new solution but when you ask them questions about it, they have NO CLUE how to answer and then they put you on hold again. Nothing gets solved and after HOURS on the phone, I just tell them to stop because we are getting no where but running around in circles that make no sense. THIS A NIGHTMARE!!
So I totally gave up on being able to upgrade this machine. To any future buyers, I STRONGLY recommend you do all upgrading BEFORE you get it home for the first time. Make sure you have your power supply and graphic card INCLUDED before you bring it home or you're mostly likely going to have a NIGHTMARE upgrading it later.    Technical support is a HORROR STORY and expect to be WAITING for LOOOOONNNNG periods of time both ON THE PHONE and ONLINE and probably ending up with NO SOLUTION in the end.
I've VERY upset with how this turned out!! I'm just gonna have to deal with the fact that my computer is permenantly messed up and NOBODY AT LENOVO knows how to fix it. So I'm stuck.
I decided to send back the new power supply and the new graphic card because of this nightmare with tech support. I put everything back to the way it was when I bought the computer and it is STILL acting up!! I just want to revert it back to factory settings .. INCLUDING THE BIOS... but Lenovo said I have to send the WHOLE computer back to them to do that. All I can do from home is restore from a point in the hard drive and that's not enough. I need a TOTAL CLEAN INSTALL. Everything needs to be wiped out and reset, not just restored to a previous restore point. I've done this multiple times and all it does is erase all the programs and stuff I put on the computer. The drivers and other codes are still the same. And then bugs come up and things get all wonky. I NEVER HAD THIS PROBLEM BEFORE I TRIED TO UPGRADE IT!!
I am NOT comfortable with Lenovo's "solution". I do NOT want to send my computer back to them for them to reset it with factory disks ESPECIALLY when they stated that they are NOT responsible for any damage in transport or otherwise. I have to buy extra packaging to make sure it gets there safely. They told me to use the original box and packaging, that is the only way they can be sure it will get there safe. Who has the original stuffing SIX MONTHS LATER?!?! I don't want to be sending my computer across the country to get jostled all over the place and have that add to the slowness of the hardware because it was jostled.
Can't I reset it from home? Can they not send ME the disks instead of me sending my whole computer to them?
I'm so incredibly frustrated with this. I hope somebody answers quickly and that I don't have to wait DAYS to get a response again.
I absolutely LOVED my Lenovo computer! And then I tried to upgrade it. BIG MISTAKE!! Now everything is totally messed up and Lenovo's customer support for technical problems is HORRID!!
Somebody please help. This is driving me crazy with frustration and totally breaking my heart. It took me a VERY long time to save up for this computer and it was my most loved possession. It was a reward for a lot of hard times and now it's all broken and acting slow. And it's only 6 months old.
Is there a solution to this very frustrating problem?
I just want it to go back to the way it was before.
And is there a very low cost KNOWN TO WORK WITH THIS MACHINE upgraded graphic card and power supply? Is there a very specific brand and make? If so, could you let me know what it is in case I try to upgrade it again someday?
Thank you for your time and for reading this!
Please have a FANTASTIC day today!!

Elite m9200t. Just quit working. Does not go into bios. new power supply - nothing but fans.

HP Elite M9200t

Error Messages: None
No changes made to system.
I hit the turn-on button one morning and nothing happened. Looked in the case and was running except the case fan. No lights were on. I tested the power supply and it tested good. Tried again - nothing. Connected a new power supply and tried again; Lights worked and cpu fan worked, but no attempt at boot.
I have disconnected everything - same result.
Does this sound like a bad ASUS mortherboard?

Heather, the PSU for the first gen G5 iMacs and the ALS models are the same physical size, but the ALS PSU is an auto-switching 110-220v model. Nice to have, but not the cause of the problem if it is working correctly.
Is your first gen one of those effected by the Repair Extension Program? If so, you actually have 2 years on problems related to the PSU and video.
Give Apple a call back and see if they have any suggestions, but don't let them put you off as you are still within the warrantee.

DC5750 New Power Supply Problems

I have a DC5750 (mini case). Everything is working fine with it. It comes with a 300W power supply. I am in the process of purchasing a new video card for it but the video card requires at least a 500W power supply. I purchased a Cooler Master Extreme Power Plus 550W PSU (http://www.coolermaster.com/products/product.php?act=detail&id=5888).
When I plug in the new power supply and turn on the PC the fans start to spin and then stop and the front power LED goes red and i get 9 continuous beeps followed by a couple of seconds of silence and then the pattern repeats itself. I have checked the HP website documentation for the DC5750 and it says that when you get these beeps to make sure that the correct voltage is set on the back of the PSU. I have made sure of this, it is set to 115V. There was also a long paragraph about the kind of power cord that you should use and I did use the one that came with the PSU and also the one that I was using before hand, but no still dice.
I have unplugged everything except the power to the motherboard when testing it and still nothing. I have sure that the 4-pin connector that goes from the PSU to the mobbo is labeled P3 to match the label on the motherboard. I tried putting in the old power supply and everything works like a charm again.
I read somewhere on these forums last night something about the CPU fan sensor and how some people had to trick their systems into thinking the power supply was putting out the same voltage as the original one. They did this by connecting two pins together but there was something about the fact that the pain had to be rated at 100ohms or something. I couldn't quite understand the solution and since it wasn't my same PC model and it was an old post I decided not to try anything of that sort just yet.
Like i said, the PC was running fine before and it is still running ok right now with the old power supply, I would like to upgrade the PSU though with the new 550W one. After i put the old PSU in i went back into the BIOS to see if there was anything related to the power supply that would stop it from booting but I didnt see anything relevant.
Does anyone have any ideas?
Thanks,
BD
Edit: I just tested the new PSU on a different system and it works just fine.

Do you remember that post about creatind a resistor connector to bypass? I have a fan not detected eror with my new PSU on the DC5750.

New Power Supply - Can't detect Driv

I installed a new power supply and once booted there is no sound card detected. I re-installed the latest drivers with no change. Anyone have a clue?Audigy 2 ZS PlatinumMessage Edited by cashmoney88 on 03-6-200706:54 PM

I had similar problems when I tried to use an MSI GF4 Ti4600 and Windows XP Professional locks up at the splash screen. I also tried a Leadtek GF4 Ti4600 and got the same results. I had already upgraded my power supply from a Antec TruePower 330 watts to 480 but to no avail.
Turns out the problem was caused by my brand new Gigabyte GA-8IEXP rev. 1.2 motherboard not fully supporting AGP 2.0 voltage requirements required by the power hungry GF4 Ti4600 cards though their tech support would not confirm nor deny this. Even upping the core and AGP voltages via the BIOS didn't help.
I then bought an Intel D845EBG2L motherboard (that stated AGP 2.0 compliance in the manual in addition to AGP 4X support) and the GF4 Ti4600 ran great :P

New internal power supply and iMac still not powering up

I recently purchased a new internal power supply for my Intel iMac and after being installed by a local Mac repair shop it still will not power up.
Are there any other issues that could cause an iMac not to start up? The logic board?

I did try to reset the PRAM and SMC before the iMac went completely kaput. But now, even with a new power supply, it won't even turn on. Maybe my replacement power supply is damaged somehow. But the repair shop said my original power supply looked like it was in good condition. Maybe they can test the original one somehow?
So my question is still: If the power supply is good, and if the hard drive is good, but the computer will still not turn on, what is left? Could the logic board be the only remaining culprit here? Are there other factors that could cause my iMac to not start up?

Green light on new power supply but no power

I have a 2 year old HP Pavillion p6654y desktop. It was working excellent until the 2012 olypics when it just shut off while i was watching table tennis. the warranty had run out and it was cheaper for me to just buy a laptop at the time. I recently plugged it up just to see if it would work. It would not work, so i looked at a couple of forums and it seemed as though i had a power supply problem. I purchased a new one and installed it, took out the battery that looks like a watch battery for 3 minutes and put it back it in. there is power going in because I have it the ethernet wire plugged in and the light on my modem/router is on. Also the light on the power supply is a steady green. lastly the motherboard light is on. I have checked all the wires blown all the dust out. I still have nothing, any suggestions?

Hey denwood35,
I'm sorry you're running into this no power issue.
I would first suggest trying different monitors.
Next you could try swapping out the RAM. If you have two sticks, try just one stick in one slot at a time, or try known-good RAM from another computer.
Does the computer stay on indefinitely when you press the power button to turn it on? Just no image on the screen? Or do the fans and lights go off on their own after a few seconds or any length of time?
What wattage is the new power supply?
Let me know the results of those tests above when you get a chance
