SOURCE: Not turning on, has power and everything

Do any of the fans spin at all, as though it's attempting to boot up? If not, then double check your power supply to see if it has a switch on it and if it does then make sure it's switched into the ON position. If so, then I would recheck the power connector(s) to the motherboard. If those are well seated then I would start looking at the power switch itself. Those go out from time-to-time. Unfortunately, several eMachine desktops of this model type that I've personally worked on had faulty components on the motherboard; which resulted in having to replace the motherboard. The typical symptoms are that the fans spin and it tries to boot-up, but then nothing else happens: no POST beeps, no video - NOTHING. I have had some of them that just wouldn't show any signs of power\life. I've also had a few of this model type that just stopped working when the power supply went out. The likely cause of that is that the power supply will usually surge when it's dying out; which often results in burning out one or several motherboard components. Once you've reverified that all your cables are connected properly, but you still don't get power, find the 2 wires that connect to your power switch on the case (in your model it's usually the black & white twisted wires. Disconnect the connector, use a small flat-head screwdriver to touch the 2 pins that the connector was attached to. Be careful, there is electricity passing thru these 2 pins when touched together (jumpered), as well as the other pins if you accidentally touch the flat-head to another jumper pin. It should only take a second of jumping the 2 pins for it to start. If it still doesn't start this way, then I suggest replacing the motherboard. You can find good Micro-ATX motherboards on ebay for pretty cheap. If you still want to use your current processor, then make sure you get a motherboard with a CPU socket that's compatible with your CPU. I believe that your CPU is compatible with Socket 775.

Gateway NV5337u Laptop worked yesterday, now only the blue lite comes on when plugged in. No fans or any other sounds.


We might need to talk more, to clarify to solve this promblem. First of all, have you done any update at all to the system? So by what you mean is that when you would go ahead and press the power on button, you get nothing at all... I mean dead, no lights, no fan, completely dead right? But when you have the charger plugged in, the battery light come on only saying it's charging? Is this blue light the battery indicator light, if it is, then that means your battery is fully charged. Try taking out your battery and just using the power adapter and press the power button to see if anything comes on, like fan, lights etc, then try it without the power adapter and only the battery. If you get nothing at all coming at all, I would assume your power button is bad or loose, or the wiring that connects to your powerbutton is loose because i have a gateway Nv series too, and the power button is located where the screen hinges is at, and I'm afraid that when opening and closing, it became loose. This happened to my Emachine, and all I did was took the plastic portion above the keyboard out, and followed the cable ribbon to see if it was loose, or became little disconnect. I kinda just tugged in a little bit and everything worked. I believe it may become loose. Now if the case is that the computer does power on and you get blinking lights, then we are looking at something else.

Nothing on my Emachines computer will turn on.


I would recommend rechecking your connection to the motherboard. All wires from the power supply to board and making sure the front panel switch connection are correct. Also, make sure the power supply is compatible to the motherboare. even though a 20-Pin ps will connect to a 24-Pin board, it still does not work. Good Luck

Need schematics for front panel , power sw , pwr led , hdd led et


Try this link to Emachines page. After you put in the make and model and stuff you should be able to view the user manual for your machine. If this isn't what you need you are able to contact support from this page and maybe they can direct you to a more detailed explanation that may help more.
eMachines use specially-made boards for them so there is no manual as such as the boards aren't made to be distributed. Basically they would all use the same sort of connectors and blocks (and cases) to an extent that anybody can plug a connector into the right place and it will work.

The easy way to get round this is to find the power button first - try each two pin connector first, press the button and see if it comes on. If not, move along on the block until you find the right one. Then it's just a case of trial-and-error on the other ones to find reset, power LED and HDD led.

Power button wiring


A quick google determined your emachines model w2040 is equipped with FIC motherboard AM37. Download the manual from
http://www.fic.com.tw/support/motherboard/motherboard.aspx?model_id=107
You'll find the pinout info for your wiring on page 13.
Most motherboards also have the pinouts silkscreened onto the board itself.
