Question about Intel CELERON 2.66Ghz CPU AND MOTHER BOARD (CPU4266CEL) Motherboard

Emachine T3828 power switch connection to motherboard

My machine would not power up, I replaced the power supply BUT when I disconnected the wiring from front panel switches I forgot which of the three go where on the board... tried finding diagram to no avail.. anyone know?

I assume maybe that is my issue but I have tried different combinations to no avail... no power to fan etc. However read maybe the motherboard is fried (there were similar posts about not getting machine to power up even after replacing the power supply etc.

Thanks in Advance !

    I have the same issue. I can't get the machine to boot. No fans, nothing. I have tried the CMOS battery, new power supply but still no success. I have a green light on the MB but that's it. I had disconnected the PWR S/W, PWR LED and PWR HDD and I am unsure where they should reconnect. Emachines manual is of no help and the MB manual doesn't help either. It looks like the MB is done but if anyone has fixed this I would love to hear about it.

The "Ultra Helpful Instructions" that Emachines provide (here: http://downloads.emachines.com/userguides/8511279_eM_NG3_chassis_HW_ref_en.pdf) state that when replacing the system board, "18. Attach all cables to new system board", but fails to say where that would be for each cable.

The site below says it's a genuine Intel board in there, so, congrats on that. http://www.e4allupgraders.info/dir1/motherboards/socket478/D845GVSR.shtml

And with that, the link to the manual:
ftp://download.intel.com/support/motherboards/desktop/D845GVSR/SR_English.pdf

You're looking for the info on page 32, I believe.

See if that fixes it up. If not, post back.

I would try a number of things... To start try and find another fan connection like for the CPU or CHASIS. Remove all power from MB even the ATX PSU Connector, then remove all CARDS and RAM so your MB is sitting without any thing plugged up to it. Take out the little battery to the CMOS and let the MB sit like this for 15 to 20 minutes... Replug everything and turn on, if the fan will not come on then you might not be powering the Power SW which you can trip with a metal screw driver to turn the PC on... If your fan powers up full speed and will not lower the RPM's at all then it is most likely a bad MB.... If nothing happens at all then you probably have the pins in wrong like the Power SW... You can find a manual here: http://www.emachines.com/support/product_support.html?cat=Desktops&subcat=T-Series&model=T3828

I have an Abit IC7-G motherboard. Machine has died with no reaction from pressing power on and reset buttons. Power cable in is OK and when connected, green light behind IDE1 socket lights up (which says...


Most obvious problem would be the power supply. The green LED only indicates that the 5V rails os working enough to power the on/off circuit on the motherboard. First disconnect everything except the mother board from power supply. Then try switching on again. If this does not work, then disconnect the power connectors from the motherboard. ON the big power connector (P1) there should be a green wire with two black wires either side. This is the power on sensor wire. Use a paper clip or similar bit if wire to short out the green wire with one of the black wires. This should start the power supply and the fan in the PSU should spin. If this does not work then the PSU is definately faulty. If it switches on when there is no load connected then it is probably only slightly faulty (not able to provide sufficient current). Since the green LED is coming on, my guess is that you have bad capacitors in the PSU (they will probably have domed tops instead of flat). Try a power supply from another PC if possible.

Will not power up


This is a common problem with Emachine motherboards, the problem is the power supply is a best tech and allows voltage surges to the motherboard which fries it too. If available you usually have to replace both the power supply and motherboard. I do not know what exactly goes bad on the motherboard but I have replaced many emachine power supplies and motherboards. The motherboard kit which used to be available from Emachines included a power supply and no warranty if you didn't change the power supply. They knew they had a problem.

Emachine t2824 board diagram


Here is the diagram that shows you how to hook up the wires:

http://www.fixya.com/uploads/images/284ECAC.png

If you still have no video then reseat the memory one stick at a time in one slot at a time.

If you still have no video then reseat the cpu into its slot.

If still no luck try a different stick of RAM by trying it one slot a time.

Last step, unhook the power connectors from your device so the only power connectors that are connected are the power to the motherboard and the p4 connector to the motheboard. Also make sure your power supply is set to 115v. Its the red switch on the back of the power supply.

If none of this works, then the motherboard is bad. Hope this information helps.

I am an emachine specialist. These computer suffer with problem motherboards which often blow the power supply unit. Replacing the power supply on it's own does not solve the problem as the motherboard processor socket is the cause of the problem, the fault in turn blows the power supply. The same applies to all Advent and Medion computers sold via the high street stores.

Power problem


Please do NOT TRY TO SWITCH ON your comp in same condition again as you would be damaging it further. Its not your power supply alone there EXISTS A SHORT CIRCUIT IN OTHER COMPONENTS as well . The SHORT CIRCUIT Protection circuit of your Power Supply senses this and switches off preventing further damage . Well you could try this - Disconnect power to all the componenets like HDD , CD/DVD , MOTHERBOARD and FDD etc.,. Plug in the AC input power to your Power supply and on the 20 pin connector look for green colored wire and black wire on the same connector and short these 2 wires ONLY with a metal paper clip or a piece of wire , if the fan in the PS works and spins at full speed till you disconnect or remove the short between the two wires (Green and Black) then your PS is Working FINE . Now connect each of the component's power connector only and repeat the same exercise you will be able to identify which component is shorted.

Intel emachine t3828


Geeze, after working on hardware for 27 years i love the short circut dummie. Anyway yes, it's the motherboard / yes the green light will still come on on that model and quite a few other models. Dont worry about repairing / i.e. removing components on the motherboard, it's a fruitless endevor but a great way to waste time. A motherboard for that model will cost about 100-150 bucks / easy replacement. It's actually rare for both the power supply and mother board to go out on a tower/mini tower type system. Older laptops had that type of prob. Those emachines were **** for the mostet part. On the other hand Gateway has really gone up in quality and i have been quite impressed with them in the last few years...
