Emachine w2646 won't power up

I have an emachine 2646 which seems to have blown the power supply. After some research I learned that this is a very common problem which often results in damage to the motherboard. Would the damage be visible? Is it still possible to retreive my data from the hard drive. Thank you

The damage would not be visible. 9 times out of 10, a dead power supply does no damage to the motherboard.

You might try posting a request on freecycle.org for a working power supply from a used (dead) computer. That way you could find out if a new power supply will fix your problem without spending the money up front. You could also go to a local PC repair shop and ask if you can return a power supply if it turns out your PC is fried. Many folks will let you do this.

Put the hard drive in another computer as a slave drive or second on cable select. boot and then access the hard drive. Your data should be there.

Hi Nicki,
Sorry, this really sounds bad, it would seem that the hard drive is shot from your description. The data may or may not be recoverable. If you get a new drive, you will have to partition it first, then set it as your Master drive, then set the old one as a slave, install your operating system onto the master drive and try to recover the information on the old drive after you have that done. If you cannot successfully recover the information that way, you most likely won't be able to get it at all unless you backed it up onto a flash or cds or dvds.
Sorry for the news but that is what it sounds like

1.) remove battery
2.) press and hold the power button for 10 - 30 seconds
3.) replace battery.
4.) when the system boots it will say press XX (e.g F2) to load defaults and continue ,, press that key.

If you have a Yellow light on power supply, chances are you have blown the power supply.
Even with a PC unplugged in a Bad Storm, I have seen many PC's and Laptops with Supplies shoot.
If you have a little computer savvy, the best thing to do is,
1. Disconnect power.
2. Open unit.
3. Disconnect all Devices from supply.
4. Disconnect 20 04 24 pin power supply connector to mother board.
5. If you have other connectors such as 4-pin 24 Volt acc. you can disconnect that as well.
6. Now plug in the supply. Note... Some supply's have a reset located in the rear of the supply, where it makes its input ( A/C connection. ) If so try the reset. Some supply's also light up or have a service light when sensing input power, some do not.
7. If all looks good and no sparks or flames, re-connect the mother board connection, (only)
Try to power on computer.
Note..... If you still have the Yellow light, Replace the supply.

In some cases, the power supply sees a fault and fold back to a protection mode.
The supply has several Capacitors in which hold a charge and when connected to the mother board retain that charge. Disconnecting the Mother Board 20- 24 pin connector will allow this charge to dissipate.
If all works after reconnecting supply, Your Good To Go.!!!
If not, you may need another Power supply.
Or may have done other damage.

Hope all works out for you.
Try it, it may work...

Thank you.

E machines w2646 video card replaceable


It has only some shared video memory onboard, so it won't be replacing.
The information i can find tells that the motherboard features an AGP-port, so you can just buy an AGP video card and place put it in the agp port on your computer.

W2646 crapped out


Some eMachines computers (like many from Dell) use a non-standard pin out for their power supplies, so if you try a standard ATX power supply it may not function.

However, in my experience it IS likely to be the motherboard. Luckly I have been able to replace quite a few of the eMachines mobos with a standard mATX mobo, since you can probably remove the IO plate. You'd certainly want to replace the power supply when doing so.

Power Supply Problem


Hi, I came acroos a similar problem on an older model of emachine. If I remember it right what I did was to update the chipset and agp and other drivers (especially the lan card). The T5026 uses Intel 915GV. Most of what you probably would need can be found at http://downloadfinder.intel.com/scripts-df-external/Support_Intel.aspx?lang=eng. Most of the updates are chipset and OS specific. Good luck and please let me know how this works out for your. Cheers.
