Satellite power supply dead

Greetings,
My Satellite U505-S2950 power supply had no output.
After about an hour, I was looking for a replacement at Walmart.
I bought one and tryed the original Toshiba. It worked! Oops It lasted about 10 minutes!
It's out again, this time for the count. Dead, Dead.
Has anyone had this happen?
Thanks,
Bigdrag

Hi, Please take extra care with replacement parts. It is a geniune part? Does the part number matches with your original adapter part number? Also make sure that the output corresponds to your laptop power source specification as doing otherwise may damage your laptop.
My suggestion is that when dealing with chargers and batteries always go for original parts. Although might be more expensive they are the safest.

IMac 700SE - power supply dead? can i get a new one?

well the power went out last week, and when it came back up my iMac did not
right now, i plug it in, hit the power button, the power light flashes, i hear a click (about a half second later), then it just goes off and the power button stops responding it to anything, i unplug it, plug it back in, hit the power button and the same thing happens, to me this sounds like a dead power supply as i have had this happen on a few PCs and when the power button stops functioning that to me sounds like its the power supply overloading, and in this case meaning its dead
now i don't really want to spend the money on a new computer as this is only used by my mom every few couple of days for email/IM/web, so does anyone know where i could get a replacement power supply? (i think) its a sliver shaped board that attaches to the main board and makes me think that i will never find a replacement unless i buy another 700SE iMac off ebay

nope, didn't help, nothing changed with the new battery
though i did notice that it booted when i didn't power up the drive (no power cable to it), but that has nothing to do with the battery, i also tried pressing every button attached to the board and nothing helped, so to me it looks like the power supply can't spin up the hard drive (the drive is good too, its in my other comp right now)
does anyone know how compatible the 400Mhz iMac is with the 700Mhz parts wise? i'm suppose to be getting a 400Mhz iMac soon, and would like to know if i could swap out the logic board on the 400 with the one from the 700 as that 400 one has a better screen and working power supply, but i would like the nice speed boost

Power supply dead? Can I get at the Hard drive?

I recently had a storm which blew one of my external firewire drives (it goes on but won't mount) and when I tried using my older G4 (Quicksilver, with OS10.3.9, and Classic) to boot up in OS9 and try my Norton Utilities, the G4 froze. It did it several times. I eventually pulled the power cord. When I plugged it back it, there was a spark (at the plug in point on the G4, not the wall outlet. Since then, it won't power up.
I tried booting it up in firewire disk mode and using my Intel MacPro, but no dice.
I did a search and have seen discussion on what sounds like my same problem. I hold the power button and the light goes on, but goes right off as soon as I let go.
I tried pressing the PMU; I saw a lot of discussion about the CUDA button but it seems these are one and the same thing. I removed the small battery and tried to get a replacement but have not succeeded as yet. Though I don't think that's the problem. It might be the power supply.
Anyway, here's my question: can I use the power supply and/or battery from an even older Mac, a PPC 8600?
And, whether or not that works, can I yank the hard drive from my G4, along with a second internal drive I put in (slave) in order to get data of it? (I'll give up trying to fix the G$ itself if I can just get my files off it.
*While I'm at it, can I take apart the external firewire drive that won't mount, and get at the files on that in some way. I tried Data Rescue ll but the drive still would not mount so that was useless.
Any help on any of these will be greatly appreciated. (Yes, I do have a nice big powerful UPS but the G4 and the external were no plugged in to it).
Thanks

Hi-
To recover your hard drives and data (including the external) get yourself a housing, and insert a drive, and move data to a different computer.
You'll want a firewire external housing with the Oxford chipset. I can recommend any of the FW or FW combo housings by OWC on the following page:
http://eshop.macsales.com/shop/firewire/add-ons-and-hubs/enclosure-kits
You will need a QS power supply-others won't work.
If you end up wanting a power supply for the QS, check eBay, or the following:

As for the battery, as long as it is the same 3.6v and form factor, any will do:

Power Supply Dead?

I recently and unexpectedly acquired an iMac G3 DV (transparent graphite case/400MHz/Slot-loading DVD-ROM). It's not working--when you push the start button, you hear a series of quiet, quickly-paced putt-putt-putt sounds and nothing else happens (drive doesn't spin, display stays black). Anyone know what's up (or not up) with this thing? Thanks.

It has 10.4.8 installed on it but it has yet to boot; the previous owner is an idiot who has no idea what ever happened to it. If it were the logic board, you'd probably hear something moving--a drive spinning or whatever--but there's nothing making a sound except for this sound. PRAM battery and power supply are good guesses. I'm not interested in this thing enough to pursue it much, but thanks for your help/

PMG4 MDD Power Supply dead? Where can I get one?

Does anyone know of another source for the PMG4 MDD Power Supply? When I press the power button to turn it on, nothing happens. Yes, I have reset the PMU, replaced the battery, left it unplugged overnight, and still nothing at all, no lights noises or anything.
I think it's the power supply, and my Apple Authorized Service Center says they haven't been able to get a power supply for over a month now.
Is there a shortage of the Samsung Power Supplies for this?
Thanks,
Jay

Thanks for the help. After calling my Apple Authorized Service Center asking what the ETA was, they told me to call 1-800-MYAPPLE and ask about the status of the Power Supply they ordered on April 24th. I called Apple yesterday, and today I got a call that the Power Supply was being shipped out today.
Not sure where the bottleneck was (Apple, AASS, etc.) but it took over a month for one to get shipped out, when the MDD G4 that blew a PS last month had one replaced in 2 days.
I am speculating that these Power Supplies have been failing at an abnormally high rate lately, and are out of production. Of course, that is just a guess.
Hopefully someone out there benefits from my info here.
Thanks,
Jay

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.

Power supply fan dead - help? (400mhz AGP G4)

Hello!
Unfortunately, my PowerMac G4, a 400mhz, AGP Sawtooth model, has a dead fan.
Over the last few weeks, I've noticed that my G4 has been running quite hot. I figured it was due to the hot dorm room that it's being used in. Then, I noticed that when it booted up, it would occasionally make a vibrating, or rattling noise - I figured the fan was wobbling. Since air was comming out of the fan opening at the top, I didn't worry about it.
Today, I used the "Temperature Monitor" widget to check the temperature of my SMART Hard drive (the G4 itself is not sensed). It was 133 degrees!!! This is the bay on the back-right, just under the CPU fan. I looked at the fan again - not much airflow. I pulled out a flashlight and pointed it in, and the Fan that's inside the power supply unit is dead.
So, how can I fix it? It's far far too hot, so it's not usable until I can cool it off. The first idea I had was to take a particularly powerful desk fan, and make a paper "tube" that connects both to the G4 and back of the fan - so it'll pull the hot air out. Needless to say, this is not a good log-term plan as it's easy to fall apart and will have leaks, but it works for now. I realize you can buy power supplies, but for ~$100, it's far too much for the old G4.
Second idea: The fan is inside the "non-user servicable" power supply, but it's also next to the back of the G4 - right inside what appears to be a panel that holds the power supply in. At the very least, I'd like to make sure that the cable is attached and not loose, but I have to open the back. Is that possible or safe? If so, can I replace the fan?
My third idea was to attach an extra fan to the inside of the G4, on the outside of the power supply - pushing in. Unfortunately, the IDE cable from the DVD drive is in the way, and there's not much room for a fan. Plus, there's no fan power supply. Is it possible to convert an ATA power plug (there are 7!) to a fan-power supply? I'd require a small circuit and a lot of resistors, obviously! If so, what would I need to do to convert it?
Thanks a bunch,
-Dan

Thanks!
Interesting, this "Piggy back power adapter" will allow me to plug the fan into one of the ATA/IDE cables? Or do you mean the extra port on the power supply? (it has one plug for the outlet>G4, then another to support something like a monitor or similar) The G4 has a DVD burner, but no ZIP drive, so this is quite do-able if it uses the ATA power.
When you say "lower rear", do you mean at the bottom? Below the power supply, to the right of the PCI slots? If so, this is the inflow for the CPU fan! I can understand mounting it outside the current outflow-vent for the dead power supply fan, although I'm not sure the best way to proceed with attaching the fan.
Another question: what tools and supplies will I need? I may need to remove the plastic cover on the back of the G4 - the one that is outside the power supply - as there's a gap between the gray plastic and metal chassis that lets air from outside the machine come in. The screws for this cover use a funky, hexagonal screwdriver. If I need to take this cover off, what kind of screwdriver will I need? Also, should the fan not include screws/etc, what's the best method to attach it? Glue?
Secondly, to cut a hole in the G4, will I need some variety of drill? I don't have one, so i'll have to borrow one... Since there's nothing in the ZIP slot, I can run a cable out through here (assuming it's long enough), and make a new bezel to keep the airflow inside intact.
Ah! One other (somewhat related) question: my USB 2 card includes a power adapter, for use when several un-powered devices (flash drives) are attached. It works just fine with a flash drive and a small media reader, but it's slow to sense the drives - I think it's low on power. Unfortunately, this power plug uses the same variety of plug as the floppy disk drives found on many win-boxes - of which the G4 possesses none. Is there an adapter/cable for this purpose?
Thanks, this is a HUGE help, I appreciate it.

QuickSilver G4 (M8360LL/A) Power Supply W/Dead Fan, Would Like To Discuss

Hey Everyone,
I recently discovered my Power Mac QuickSilver G4 (M8360LL/A -- http://support.apple.com/specs/powermac/PowerMac_G4Quicksilver.html) has a dead fan within the power supply. Running an open-case test shows all other fans are working fine. Currently I have a high RPM floor fan blowing A/C air directly into/against the rear of the chassis.
I've done some research on my options, but would like some help making the best choice:
(1) Purchase a replacement power supply.
(2) Install a replacement fan directly into the power supply since it still appears to be functioning normally.
(3) Purchase a cheaper alternative, but compatible power supply?
I'll discuss my research into each possibility in order:
(1) I've found a small number of sites selling replacement power supplies for the QuickSilver G4 systems (shipping not factored into the prices I'm listing):
(a) $174.00 from DV Warehouse (http://www.dvwarehouse.com/Power-Supply-344-W-PM-G4-Quick-Silver(733-800-867-933-1ghz/Dual)-p-20361.html)
(b) $179.99 from Mac-Resource (http://www.mac-resource.com/store.php?item=6612513.PART)
(c) $219.95 from WeLoveMacs (http://www.welovemacs.com/posu344wapog.html)
(d) At the time I searched, I didn't see anyone selling the same model power supply on eBay.
If I choose to purchase a replacement, I'll most likely go with the cheapest vendor since it's listing the part as new.
(2) I'm not confident enough to attempt a fan replacement, and since the power supply fan has been dead for an unknown length of time, I'm not entirely confident it hasn't been damaged from excessive heat. If anyone has a link or useful document that explains how to replace the power supply fan safely, I'd be open to the option. Right now, the most information I currently have is the physical specifications of the original fan (correct me if I'm wrong!):
Protechnic 80x80x25mm MAGIC (made by Sechang Micro)
12 Volt, 0.24 Amp
38.27 CFM, 3000 RPM (max), 29 dBA
P/N: MGA8012HS
I would probably want a better alternative if I went this route, since I didn't expect the fan to die quite this soon (although I generally run my system 24/x7).
(3) I found this other post where another G4 QuickSilver user had the same problem: http://discussions.apple.com/thread.jspa?messageID=2198292
That thread has a link to the following site with recommendation for purchasing power supplies:
http://www.Performance-PCs.com/
However, I've limited experience with voltage requirements and I don't know anything about the physical connector or dimensions of the power supply itself. At best, I know the model of my power supply is 614-0157 and can max out at 344 W.
If anyone has input and suggestions to help me fully explore my options, I'd really appreciate it. Otherwise I'll land on safe ground by buying an entire replacement of the same model, swap it out, and be done with it.
Power Mac G4 QuickSilver (M8360LL/A) Mac OS X (10.3.9) 2 GHz Processor Upgrade (Giga Designs), 1.5 GB RAM, 5 Internal HDDs

I decided to purchase a replacement power supply from DV Warehouse, since it was the cheapest vendor I could find selling the part as new.
When time permits, I intend to open the original power supply cover to see how challenging it would be to replace the fan. When I do, I'll add more about it to this thread.
One thing I'm noticing with this power supply fan while it's still in use with my system: If I push on a fan blade with a plastic stick while the system is powered up, I'll see the fan revolve a little (very slowly) before stopping. Not sure if that can be a useful clue as to which component within the power supply could have failed.
PB PM - About your earlier comment to blowing A/C air against the back of the case being more of a hinderance than helpful, is that true even when the component has no assisted airflow at all? In other words, my logic in using a floor fan to force colder air into the power supply is to help cool the components within it since there is otherwise only natural airflow to help keep the PS from overheating.
Thanks!

HT201263 iphone has completely dead, it wont connect to power supply or PC and won't re charge

My iphone 4 has completely died - it wont connect to the power supply, wont connect to PC nothing - any suggestions ??

Maybe the fact that it's dead has something to do with it...?
If a reset didn't work, make an appointment at the Genius bar and let them look at it.

Satellite P55W-B5318 Power Supply Very Hot

I purchased a Satellite P55W-B5318 yesterday. While charging the laptop the power brick got very hot, too hot to handle for more than a few seconds. The model number of the power supply is PA5177U-1ACA. I read Toshiba has replaced some power supplies which ran hot. Should I request a new power supply?

You should call Tech Support at 1-800-457-7777 immediately. It should only get warm to the touch. But the best thing to do is take it back where you bought it for an exchange.

Satellite Pro S300L-105 - Whistle when power supply is removed

I recently bought a Satellite Pro S300L-105, it works normally except that it produces a slight, pointed whistle, witch can be heard when the power supply is removed. After less than 10 minutes using, I feel pain to my ears and brain and it becomes unusable.
I do not have any hearing problem or so. and I've never had such a problem when using any other computer.
What is it due to, and what can the manufacturer do for me?

Hi
Very common problem with all sorts of electronic equipment.
The whistle is caused by the high frequencies used by switch mode power supplies. It's a bit like a car where you have a rattle that happens only at certain speeds, and that speed creates a certain frequency that resonates with something in the car that then makes a noise. The same thing happens in the power supply.
When you remove the power the laptop enters a different power mode and starts running things on a lower voltage to save the battery power, and the way the power supply does this is by changing the frequency the power supply runs at. This frequency is just right to cause something to start vibrating within it, and as the frequencies are very high, you get a high frequency squeal. It may be so high in frequency other people can't hear it, which can be a problem when support or the shop are checking are it if you take it back.
Just like a car with a rattle, not every car of the same type will have the problem and the same goes for laptops. Someone may have a squeal only when on mains power for example, or only when the back light is on full or on dim, or they just don't notice it.
The manufacturers do a lot to try and dampen down anything that might vibrate and squeal but are not always successful.
You might find turning off power management settings help as the power supply is then forced to supply more power and so the frequency shifts to one that doesn't cause a squeal, but then you will find battery power doesn't last as long.
It could easily go away after a few weeks or months and never come back, or could get worse.
Mostly the noise isn't any sign of an impending problem or breakdown.
Getting the laptop replaced will most likely get you one that doesn't squeal.
Hope that information helps a bit, I know it can drive you mad when you get a high frequency squeal, and even madder when other people can't hear as their hearing isn't as good.
The same sorts of noise are now used in areas where children hang out causing trouble, a high frequency noise is blasted out at a frequency that most adults can no longer hear but children can as it drives them insane, so if you can here the squeal and others can't that is quite normal and shows if anything you have younger hearing or are indeed younger.

S5-1554 Dead - power supply?

Computer found dead. Tried start button, no response. Followed hp troubleshooting guide: power supply has solid green light, and when paper clip placed across p1-17 and ground, power supply fan came on. However, when reconnected and push start button absolutely nothing happens. Once, all fans started to spin up for about one second, but stopped. Troubleshooting guide says if power supply fan comes on when the p1-17 to ground connected, the power supply should be good, and should then consider motherboard, memory, other causes. However, I'm skeptical. My gut still says it is the power supply. I have an older computer that died but has a good power supply that wouldn't fit, would it work to connect to see if it would power up just as a test? Other thoughts before starting to swap out parts as diagnostic?

Grumpy44, welcome to the forum. I agree with you that it could be the PSU. I have heard of PSU's working using the paper clip, but still not being good enough to power the computer. If you try to use your old PSU make certain that the ATX Power connector is correct. Please click the "Thumbs up + button" if I have helped you and click "Accept as Solution" if your problem is solved.

Dead iMac G3 suddenly won't power on. PRAM battery or Power Supply?

iMac G3 350 slot load USB only running 10.4.11
i love this little guy.
it's been running almost non stop for a few years as a file server... only restarted maybe a dozen times during that period. i can't remember ever shutting it down.
i had to move it recently. might have been unplugged from a wall socket for a minute or so. plugged it back in but left it powered off for a few days.
went to turn it on recently and nothing. not a chime, not a light, not a click or hard drive spin-up. zero. pushed the PMU reset button once. still nothing. i've taken the PRAM battery out for now.
my question is this: is it possible the power supply is dead and a PRAM battery will not fix the iMac? is there any way to tell before spending money on a new battery i may not need?
thanks!

Hello Nicholas,
I recently retired my hard working 350 slot so I know how great the computer can be.
Unplugging for a moment should not have affected the battery.
I would respectfully suggest you start with the simple things such as:
1. - Make certain the power source is not on a switch and that it is good
2. - Be certain the power chord is fully seated in the back of the computer and wall socket.
3. - If trying to start from the keyboard button, try using the button on the face of the computer
perhaps the keyboard is not fully plugged into the usb port.
I always like to start with the simple things when I have a problem.
Now that the battery is removed it could cause a bit of a problem. I think I would install the battery
and check the above mentioned ideas. If still no power, then I would replace the battery.
It doesn;t seem logical that the power supply would just go as a result of the board.
I would try to get the computer up and running.
One last tip.......when my slot load was starting to go it acted odd. I would let the computer sit for a day or two and it would then start. It was irratic at best but the old computer allowed me a few last
boots so that I could back up to my external.
It is a great computer and sounds like it served you well it deserves a few chances.
I hope you replace the battery, plug and it re-starts. Keep it plugged in once the battery is replaced/returned .....Best of Luck Jim

Satellite C660 - WLAN disconnects on battery power supply

HI
I have a new Satellite C660 which is a great wee machine BUT every time I disconnect the power cable the wireless connection looses the internet connection. Wireless is fine and all settings accurate. I have checked the amended the power settings and they are set to be ok whether on battery or power.
But still I cannot disconnect the power cable without losing the warless connection. The modem is still on and functioning and even more strongly I can access other peoples wireless connections whilst being off line.
Please any ideas?
Thanks

When you use notebook on battery power supply and use FN+F8 can you enable and disable WLAN module properly?
Ave you checked WLAN settings in device manager properties (click here )?

What power supply do I need for a dead AGP G4 with upgraded processor

I recently upgraded my 400Mhz G4 to a dual 500Mhz board and a bigger, faster HD. I also replaced the internal battery but now the Mac... she is dead. No power, no lights, no nothing.
Will I need an upgraded power supply for the new board, or is it just old and time for a replacement power supply.
I found this on Ebay... will it work?
"This 237W Astec power supply (Apple part# 614-0108) is a clean, working pull from a revision 2 Power Mac G4 AGP Graphics/Sawtooth series computer (e.g. 350/400/450/500 MHz single processor) and will also work perfectly in previous models as well. "
Thanks!
AGP G4, Dual 500, 768Mb RAM Mac OS X (10.3.9)

Hi,
The AGP Sawtooth Mac can be switched to an ATX PSU. Later models (Gigabit G4, Digital Audio, Quicksilver and later) have a different power supply and motherboard that passes 28 Volts DC from the power supply to a connector for the ADC port graphics card. (28 VDC is passed to the Graphics card ADC port to power Apple's ADC monitors, introduced in Summer 2000 MWNY.) A standard PC ATX Power Supply does not have 28V DC and will not be pin compatible with the Gigabit G4 and later G4 systems.
