Fixing power supply part on motherboard on V560

Hello, I have a broken V560. Actually, the notebook dont responses to anything, only what event is, the charger is blinking. So that is mean is somewhere a "cut-off" (short curcuit) in power supply part. Well, i disassembled the notebook and connected a charger, well, two Transistors 4407A is so much hot. I little measuring and i get is there a INPUT voltage, but OUTPUT is nothing. I calculated the temperature of 2nd CHIP, its got a 50Celsius... Well, here in Slovakia i think on all repair shops is says "only motherboard replace". But i think is another way to fix it homemade. Im not a electric newbie so i will maybe take that.. But, my question is, it is trouble only on that transistor or something other? Or, what u will be recommanding to try measure etc.. ? :-)
Thank u

HP Deskjet D1560, Need Part numbers for power supply parts

I have an HP Deskjet D1560 still in the box. Does not have power adapter and power cord. (My daughter took them for her printer.) Where can I find the part numbers for the power supply parts? I live in the U.S., so I need the power cord that will fit in a U.S. outlet. The power cords in the product section are for the Middle East, Europe, and England. I need the one for the U.S. Where can I find that part number?

The power supply is part number 0957-2231 and the associated US cord is part number 8121-0889. I usually pick these up on eBay if I need a power supply, see the listings here. Make sure the power cord is included, it may be listed as a seperate item.

Could it really be the power supply?

Having read similar instances of G4s not starting up, I have nearly concluded that my power supply is at fault. If there has been an interruption in the electrical supply, the computer of course switches off but wont reboot for many an hour afterwards. But recently it wouldn't start up after two days, and now as it shuts down it hangs just before it goes to the black screen with the ghostly image of the desktop picture. Now I have tried all that I can think of to reboot, pram and things. Replaced battery and even fuses in the plugs. I hope it isn't but I fear something is not right in the power supply part of the mac, but could it be some setting on the computer which is behaving badly, some glitch or other?
p.s. After it shuts down you can hear electrical clicking coming from the power supply box.

Hi Michael,
This is exactly the same symptons I had with my quicksilver and I managed to pick up an earlier model of the machine and swapped over the power supplys which fixed the problem. The clicking noise is a definite sign of this, something to do with the PSU being unable to sustain the load.

Depending on what company made the PS, most companies over exagerate what they will do, or give a peak power output instead of a constant rated amprage. If thier PS will maintain a constant 200watt under full load, then it will get the job done in a all-in-1 unit. Check this page for power consumption of all your parts. It`s kinda old and the values for the VC and processors could be a bit higher, but it will give you a good idea.

Power supply for HP Pavilion m7-1015dx Entertainment Notebook PC

I have a HP Pavilion m7-1015dx Entertainment Notebook PC.
The power supply (AC adaptor) that it comes with is HP part number 608428-002.
I also have a different power supply (AC adaptor) that came with a much older HP Pavilion notebook. This older power supply is HP part number 519329-003.
Is the HP Pavilion m7-1015dx compatible with the older power supply (part number 519329-003)?
Thanks!
Mike

519329-003 is definitely the right part number. I just double-checked, and that's what's written on the hardware. If you do a google search for "hp part 519329-003", you get a ton of results.
The older HP notebook has another power supply, with HP part number 608428‑002 608428‑002 608428‑002 608428-002. So I know that 608428-002 and 519329-003 are equivalent.
Is the newer notebook (the HP Pavilion m7-1015dx) compatible with the power supply that has HP part number 608428-002?

How to check the power supply? iMac G3 233

How to do it?
Can i just take the case with the mainboard out and "short" the pins Power on (pin 8) with GND and check the voltages on the connector that comes out of the monitor case?
I know that the pin 8 is the power from articles about imac>atx case conversion.And i know that you can power up a normal ATX power supply by shortening two pins, and want to know if i can do the same with iMAc power supply. I don't want to fry anything.

Sounds like you have eliminated most of the possibilities, other than power supply board or motherboard. But it may also be the CPU daughter card that is faulty. I had one (233 MHz) that would run Mac OS 9 just fine, but it was unable to run Mac OS X reliably (crashes and freezes after a few minutes). I replaced it first with a 333 MHz G3 card off of eBay and later with a 467 MHz G4 card from the Fastmac booth at MacWorld San Francisco two years ago.
If you are comfortable disassembling the iMac to the point of removing the power supply board, you can layout the PS board and the carrier assembly (the thing you pull out with the motherboard, CPU card, and drives) on a table top. Then connect the power supply board to the carrier assembly, and connect the external power cord plug to the power supply board, and connect a keyboard with a power button to the carrier.
To measure the voltages, you can disconnect the 4-pin connector to the hard drive. If you turn it on using the power button on the keyboard, it will not start up with the hard drive not powered up (unless you use a bootable CD), but the system should be powered so that you can take your measurements.
Hope that works. Be careful with the exposed back end of the CRT. Keep any curious cats out of the room while you do this...

HELP!! K8N Neo4/SLI Power Supply problem

Hi. I really need help.
I'm upgrading my computer and using my old case, a raidmax case with a 420w power supply.
The problem is, i discovered that the power supply for the motherboard is only 20 pin, while the motehrboard asks for 24 pin. I discovered that I can fit the 20 pin in theere, but still, 4 pin will be left empty. Is that okay? Or do I need a new power supply.
Thanks!

Broken power supply: is there an easy fix?

Somehow when I plugged my iPod into a (usually reliable) AC adapter at work, it horrendously bent the pins inside the power supply. Now I can't plug it in at all - and it's dead, which is heartbreaking. Perhaps I'm a bit of a fool, but I thought all iPod adapters would fit my iPod (the adapter at work had always worked before). Why did this happen?
Anyway, is there a way that I can fix this cheaply? The curt, unfriendly guy at the Apple Store told me it would cost over $100 (He was a jerk! Come on, Apple Store, upgrade your staff.). Is there a home-repair solution? Or contractors who do this sort of repair for a more reasonable price and with a nicer attitude?

No, I think I have damaged the docking port on my iPod. Or "dock connector". The pins (or whatever they're called) are bent and possibly broken. Someone said to me I could just buy a broken iPod (like with a cracked screen) and use it for parts - does anyone know if that's possible, or know of any resources for that sort of thing?
Thanks for replying, by that way.

Fixed broken power supply plug

Hi and thanks to everyone for all the info I have picked off this site.
I have read from quite a few people that they have had problems with the computer side plugs of the power adapter. My first adapter was replaced by apple when it gave up the goast. Unfortunately the replacement adapter started to show signs of impending death. Not being an expert fixer upper, but being aggressively cheap, I timed my moment perfectly. I waited until I really had to work the cord to get power, called the local apple shop and made sure they had a power adapter in stock.... then got out the knife!
Using a utility knife and a small screw driver, you can seperate the plug jacket from the meat of the plug. I then cut open the plastic packing around the cord, and unsoldered the wires connected to the plug. I cut back the wires to before the short, rethread the wires through a plastic anchor that was lodged in the packing, put that back in the cut packing and resoldered the wires to the plug. One of the wires was actually a sheathing that was wrapped around the second wire.
After putting it back together, I put some white heat shrink wrap over the plug and melted it on for support. Knowing where these supplies tend to break, I am quite confident that the shrink wrap will really protect the pluc from future breaks. Being white, it does not look like a fix!
Presto... no flickering...expensive power supply.
Hope that helps!

Dead motherboard and power supply.. now what?

I am pretty upset that my iMac had a meltdown. It worked wonderfully and perfectly until last week. The Apple store told me that the motherboard fried and so did the power supply. They told me it wasn't worth it to replace the parts since it would cost over 1200 dollars to replace. I seriously do not have money for a new computer and I do not have the credit rating that could help me finance a new one.
I've had the computer since 2004, you could say that over 4 years of perfect performance could be good, but the computer was a gift from my dad who has recently passed, and I don't think it's going to be easy for me to give it up. If I were to buy the parts myself and do the install, would be it be worth it? My questions are ... where can I buy the motherboard and new power supply? Can I buy directly from Apple and install myself? Thanks in advance for your help.

Welcome to Discussions - sorry about your loss, there certainly are places that sell replacement parts for your Rev A - look at [welovemacs.com] to get an idea of prices. Buying from Apple usually means higher prices, but you can check with them as well, part of the $1200 was surely labor costs.
Let us know how things turn out,

Problem with power supply and motherboard

I got problem with the cpu.this is the 2nd time my cpu cannot on. It keeps on off.

Help I think my power supply is going bad! Where can I buy parts?

I am getting random reboots and it doesn't seem to be the OS... My first guess is the power supply but I can't seem to find one to buy... Does anyone know where I can buy one at? Is there a good place for parts for the MEGA 180?
Thanks
Mobile Bob

you need to post more information about the problem you're having, before we start pointing the finger at the PSU, which is the one part that is difficult to obtain now
>> Getting help with random restarts and blue-screens <<
Post more info on the hardware in your Mega PC, refer to >> Moan Guide <<
Download Speedfan and use it to measure CPU temps both at idle and under load and post them here. >> How to use Speedfan <<
Test your memory using >> Memtest86 <<
The thing is that windows never leaves an error... I get nothing in the event viewer except windows was shutdown error no other errors are listed so I don't think it's windows... I ran a CPU Burn in test for over 24 hours and never had a problem so I don't think it's heat either... And the reboots are quite random I will go two weeks without one and then get them two and three times a day... To me the power supply seems to be the easiest answer but since there hard to get I guess it's not so easy to check eh...
I have done the fan mod (Turning it so it sucks in cool air) and I have a slot fan dumping tons of air out the back so I don't think it's a heat problem... I started to have the problem running Windows XP SP2 so I did a complete reload from scratch to Windows Vista (I know not completely supported but it works fine) and am still having the same problem... I have a Haugpauge 150 pci card, Haugpauge USB2, A usbuirt pluged into usb and thats about it... 2 gigs of ram 2x1gig sticks from Crucial, yes I have already run a memory check and it passed...
Is there not anywhere to get a power supply? Or is there another model that fits the mega 180 case?

2253iX California Power Supply USB Communication Issue FIXED

I figure I would post this in the event someone else runs into the same issue.
When trying to communicate to an 2253iX California three phase power supply through USB using labVIEW, it would always fail in the initalization block, when asking the unit for the model ( *IDN? ). The display on the instrument would display Error -113 "Undefined Header" Turns out the USB Com port driver doesn't work when registered as COM9 or greater. It has to be COM0 through COM8. Uninstalling a device in that range and reassigning the power supply's COM fixed the issue.

not surprising...
I have been using California Instruments 5001iX AC source and 3091LD AC load for years and communications (RS-322, GPIB, USB) have always been hit and miss when answering an *IDN? query.
Even the newer series 2 models have these issues, but seemingly only with *IDN? query.
I just put a loop in to query it several times before giving up.
Also I have found Ci's set of IVI vi's are usless crap and have made my own using SCPI that work a lot better.
What really makes me sad is Ci is still far superior than Elgar when it comes to AC power sources.
