This is a job best left to a technician. The power connector runs through a motherboard with about 8 layers of PCB.
If you want to do it yourself, then you will need a temperature controlled soldering iron and some quality solder to reattach it.
Heat the area to be soldered, and add the solder as you go. Becareful not to leave any splatters of solder on the board or it will be game over the second you apply power to it.
The other thing you will need is patience..lots of patience.

There are screws, alot of screws, and they are all tiny. Did I mention patience?

Getting them apart is also a job in itself. Sometimes just when you think you have all the screws out, there are still a few not visible. The best method is to gently pull at each item you think should be free. If it catches anywhere, then look in that area for more screws.
Oh, and did I mention patience.

It's a good idea to get a snaplock bag to hold the screws in, or get a few magnets from the fridge to keep them together.

Good luck =)

Msi laptop keeps shutting off


Is the plug in pin for the power supply unit located near the hard drive casing? if so you will need to have this input plug on the board for the power supply unit replaced. If this is not the case something is loose or cracked or shorting out when touching the HD. Make sure to see if this is plugged in correctly and the HD is not loose or dirty on the connectors. Clean the connectors with alcohol really good replace and see if that solved the problem.
I suggest because it is electrical that you take it in and have it repaired. John

Fujitsu tower smoke out of rear no power


Sounds like you need a new power supply. Have a look at the labels on the old one inside the tower. The thing to look for is the total power output in Watts.
If it's 300watts for example then buy another with the same or higher wattage, I would go for a higher one. Then check the leads that come out the back in to the drives and motherboard etc. Especially the power to the motherboard. If it's a 20 pin socket thats the standard, if it's a 24 pin socket thats the more modern type but can still be used on a 20 pin connector on the motherboard, you just don't use the other 4 pin plug thats usually seperate at the end of the plug. The power supply is usually only held in place with 4 screws on the outside of the tower.
The main power connector to the motherboard has a little clip on the side of the plug that you have to press in to remove, it's like a little hook to stop it comming loose. There may also be a black and yellow wire 4 pin plug near the pocessor heatsink on fan, that also has a clip to press.It's not a hard job, just take your time and don't apply to much pressure when connecting the new leads to the board.

Removed power cord from back of pc and after plugging it back in I suddenly had no power. Replaced original power supply (Bestec 300 W 24 pin main connector) with a new Dynex 400W 20+4 pin and still...


Before calling it quits on the motherboard, try disconnecting ALL non-essential devices from the motherboard.

This includes drive cables, all slot mounted cards, etc.

Leave the processor and ram in place. Make sure ALL power cords from the power supply to the motherboard are properly plugged in. Some power supplies have 2 cords to the motherboard, a large plug and possibly a separate 4 pin that plugs in near the CPU. After checking your plugs, see if the board will power up. If so, you should get some beeps or status lights. If not, then it is likely the board has failed. Since you have replaced the original power supply, (assuming the replacement is compatible), it is not likely you have 2 bad power supplies.

If the board DOES power up, then plug in 1 internal device at a time to determine what might be "killing" the boot. A bad hard drive or DVD/CD drive can cause this as well as a shorted USB or firewire device.

How do I replace a power supply on a Compaq Presario SR5110NX Desktop PC


you can purchase a power supply from any computer store *********** board supports both standard IDE and Serial ATA connections, so you want a power supply that does SATA power as well. Unplug the power cord from the back of the computer. remove the cover from the case and verify that there is no green LED on the board that is lit up (if there is, there is still power on the board). unplug all connections from the current power supply, including all drive power and the large 24pin plug (actually a 4 pin plug that is combined with a 20 pin plug) on the board, then unplug the 4 pin plug near the processor. careful that the 24 pin plug and the additional 4 pin plug near the processor have latches on the side. Remove the 4 screws that hold the power supply in and remove the power supply, install new supply and reinstall the 4 screws. first plug in the 4 pin plug that connects with the 20 pin, the 4 pin plug has no latch, it is held in place by the 20 pin plug. then plug in the 20 pin plug and the 4 pin next to the processor. then plug in the drive power to all of the drives. Install the power plug at the back of the system and you should see a green LED on the board when you insert the power. replace the cover and power the system up.

The internal power supply prongs are bent. How do


Hi,

Thanks for using fixya..

If the prongs are bent, all you need to do is to get a pair of pliers and try to re-align them. If that is not possible, you can try to open up the power supply and directly tap the power cable into the prong's cable line (if you have an idea how to do this, go on and try it. If you have absolutely no idea how to do it, then its better to just bring your power supply to a local electrician, they can probably fix the problem in no time)

Thanks and have a nice day

CASE DISASSEMBLY


first unscrew the cover of the computer, then
i suggest you take out all the connectors, so that you can dettach the power supply easily.remove the screws at the back of the power supply, which is in the back panel of the cpu chassis.
unplug the 24 or 20 pin connector from the cpu and all the power cords that supply the peripherals, take out the power supply and replace with a new one.
Plug the screws, plug the 20 or 24 pin power connector into your motherboard, and supply devices like your hard disk, cd rom by plugging in the power cords.
note, if your computer has a 4pin connector, make sure that you plug it in.

Heres a video tutorial on the step by step process.

Power supply installation in gateway 610xl


to replace a standard ATX powersupply;

remove left hand side cover (ensure power is disconnected first);
disconnect the 20.24 pin primary power plug (big wide white one plugs directly onto the mainboard, also disconnect the 4 pin AUX power plug, looks just like the other one but is a smaller square shaped plug (older P3 boards will not have this)

disconnect all 4 pin power plugs from hard drives/cd drives and aftermarket fans (if any are installed), disconnect SATA power plugs from any SATA devices installed (flat black plug, 4 wires)

disconnect floppy drive power plug (if app) small while 4 pin power plug, once all of these are disconnected, looking at the rear of the computer there will be 4 screws holding the power supply in place, one screw will be more to the centre slightly to ensure you do not put it in upside down, once you remove those screws the power supply will slide right out.. simply re-do these steps in revers for instaling the new power supply
