Does the device do anything? Is it completely dead? If it is, then there is a good chance the power supplies have failed. Power supplies use electrical devices called "capacitors" to filter out voltage variations which are created during the process of converting alternating current to direct current. If the capacitors have shorted out, they should have caused a fuse to blow.

Do yu have the manual for the machine?

XPS M1210 Laptop not powering up


No Power Issues on Laptops

There are 3 things to consider in order for you to determine a No Power Issue

1. Battery
2. Mother Board
3. AC Adapter


1. Remove the battery from the laptop

2. Disconnect all non essential cables (external hard drive, usb memory key, printer...etc.)just connect the AC Adapter

3. Take out the Battery....Usually there is a battery indicator that you can push at the back of the battery

4. By Now the battery power indicator should be full since it was never taken out

5. If still theres no light on the battery.... replace battery

6. Turn the laptop on without the battery

7. If the computer still did not turned on check the AC Adapter if there is light coming out

8. If there's no light that comes out from the AC Adapter. Reseat the cable from the AC Adapter to the Cord

9. Check if there is no light that comes out from the AC Adapter. AC adapter needs to be replaced

10. Otherwise the Mother Board needs replacing

1 long beep and 2 short beep


One long beep and 2 short beeps means that there is something wrong with your video. Open the side cover and make sure all cables are plugged in and also make sure your video card is seated all the way in. If it is on board video then it may be the drivers or the mother board. Check the main board for blown caps. The tops of the caps have an X cut into them. If this bubbles up then the cap is no good and the board needs replacing.

It is hard to write how to do something likethis but you should be ok if you just use a little common sense.

Things you will need: Static Wrist band (Optional) and some Thermal CompoundSuch as Artic Silver 3 and your New Mother Board manual. I would also have someQ-Tips and Alcohol on hand

Tools: A Screwdriver set (Non-Magnetized) and a small socket set or nut driverset

If you decide not to use a static wrist band you must always ground yourselfbefore touching any of the electrical components. This can be done by grabbingthe metal portion of your case with one hand and pull the parts with the other.

1. Find a nice flat surface to work on and lay an old towel down.
2. Un-hook all cable from your computer
3. Lay your computer on the towel and pull the covers.
4. Open your new Mother Board and take it out of the static bag. Lay the newMotherboard very close to where you are working. But lay it on top of thestatic bag.
5. Start pulling all your components from the Mother Board IE: Sound Card,Video Card, RAM and any other component that is plugged into it. Now would bethe time to insure that the new Motherboard is compatible with all yourcomponents. Look at the plug styles of you Video Card, Sound Card and RAM toinsure the are the same style.
6. Now I would unplug all the wires from the motherboard except the very smallwires that control your reset button, power and lights. These will be last.
7. Ok once you have unplugged everything but the control wires start taking thescrews out of the Mother Board. When n you get all the screws out slide theboard a little to the right (To get the Plug ports out of the case)
8. Now with the Power, LED and reset wires still hooked up.(This should be the only thing still plugged up) lift up and lay the old motherboar on the upper corner of your case in a fashion that it will sit withoutholding it.
9. Now grasp your new board with the static bag still underit and sit it on the corner across from the old boar. You now need to locatethe pins on the board that the LED, Power and reset wires plug into. If theyare not marked on the board you will need to look this portion up in yourmanual to figure out which pins go to what.
10. I would now (Once you locate what pins do what) Unplugeach wire from the old board one at a time and plug into the new board.
11. When all the wires are on the new board move the old oneout of the way. (Depending on how old your case is you might need to usespacers that usually come with the new motherboard to line up with the plugports on the back of the computer)
12. Now do everything in reverse order.

If your new motherboard did not come with a new Processor youwill need to pull the old one before you install the components back to the newboard.

  1. Take the fan off of the top of the processor on the old board by taking the screws out. Once the screws are out carefully wiggle the fan back and forth until it frees itself from the processor.
  2. Now you should take some alcohol and clean the old silver off the top of the processor. Once its clean you will see a lever on one side of the processor you will need to un-pin and lift upward to free the processor.
  3. Once free carefully lift the processor out of the socket and lower it into the socket on the new mother board. This will only fit one way and don’t force it or you will bend the pins. It should freely drop into the socket as long as your lever is in the upward position. Now you can snap the lever back down to lock it in place.
  4. Take a little more alcohol on a q-tip and clean the top of the processor again to get any oils or dust off. Now apply a small amount of the Thermal Silver to the top of your processor but cover the whole area.
  5. You can re-install your fan and plug it into the motherboard.

I tried to be as descriptive as possible and if you know alittle bit about computers your will be able to replace the motherboard withoutan major problems from this list. Some things in this process are common sceneso just think about what your doing and move slowly. I hope everything goeswell and if you have any questions feel free to ask.

EMachine T2482 Computer won't power on or boot up.


Try removing the power cable from the power supply. Wait 10 seconds, and replace it again. Try powering up the computer. If it doesn't power up, check that the motherboard has power (there should be a LED on the board which is lit up. Of course, check the fuse also in the plug.

If the LED is on, you have a failed motherboard / Switch. If the LED is off, then you have a failed power supply. Beware though, if the PSU has blown, it could easily have taken the motherboard with it.

Battery in a gateway gt5404


The battery on a desktop computer is on the mother board. It looks like a large watch battery. Very inexpensive and easy to change. But make sure all power is disconnected before touching *********** board and do not use and sharp object to try to pry the battery out.

Till (cash register)


Can you open the cases and see if there are any batteries inside? The batteries will probably be on a board and look like a coin inserted into a holder. If you are not electrically inclined, perhaps you should take it to a computer store and have them check it out.

No boot up screen


Hello.

The mother Board is a possibility, but I think that first I would check the main power supply. It is best to substitute in a known good PS to verify. If a good power supply fails to correct. I would look on the mother board for obvious hot spots or electrolytic capacitors with bulging tops or shrunken PVC outer coverings. Manufacturers have built with defective or incorrectly marked capacitors before. I have repaired several by just replacing the caps that had overheated and started to vent pressure after doming their tops.

Good luck.
