Power switch does not turn computer on

I have a e machines desktop computer. When I press the circular button on the front of the tower, nothing happens. It is like the power is dead. I tried switching out the power cord, but that did not solve the problem. There is a switch behind the button, but I do not know if that is the problem.

FIXYA The power supply output of my Dell Dimension 8200 desktop pc is delayed for minutes after i press the ON button in the tower front. The momentary button switch is OK. The delay is 15 minutes if

It's not about the switch, a problem may be caused by bad power management control driven by XP. Ask on DELL's forum about any patches about this. Finally, check-up your power management scheme.

No power to tower. Pressing power on button on front of tower fails. Is there some kind of reset or fuse to look for?

There is no easy fuse. Did the computer get turned off at the back? Some power supplies have a switch on the top of the tower. Did the power strip get turned off? Have you verified that the outlet has power?
If this is not the problem, it sounds like a blown power supply. Do you have any lights on the system? If not, take the tower to a local computer shop and they can very quickly diagnose a failed power supply.

The Power Button on the front cover of the PC tower no longer turns the PC On!

check on the back of the pc tower where the power cable plugs in, there may be a small switch that needs turned on again, failing that i would open the tower and trace the wires back to the mainboard one may have come loose

My emachine T1742 desktop will not turn on. When plugged in the power supply's fan turns on, cpu fan doesnt start, both hdd/power led's flicker and pressing power button doesnt power on/off system.

Disconnect all the devices from the computer(tower) including keyboard, mouse, monitor(everything)..even the power cable

Now keep on holding down the power button on the computer tower for 15-30 seconds..

Now release the power button, plug in the power cable, monitor, keyboard, mouse and turn on the computer...

If it works, great!!!

Otherwise, take it for repair..

I am giving you a step which you should try once and see if it makes any difference.

Method (Power cycle)

You need to unplug the power cord from the tower and also remove any other device connected to the computer (May be any additional cards or any wires as for Ethernet or speakers mouse, keyboard).

Nothing should be connected at all to the tower.

Now Press and hold the power button on the tower for 25 seconds (It wont show anything). This is a step to release any static charges developed, which may surely caused the kind of issue you are facing.

Now connect the Power, keyboard and mouse and check, it should certainly work now.

Hope this should help

E-machines desktop PC will not power up at all

1) Check and see if the switch on the power supply is turned on (if there is one).

If it still won't turn on then most likely the power supply is dead. It's not very expensive to replace.
The other explanation might be that the power-on switch maybe broken...

Power problem

look for a switch on the back of the computer by the power supply it must be in the I position not the O . if that will not work then the motherboard my be damaged or the power supply itself not the cord for it is very rare for a power cord to polarize any more. last the power button itself may be damaged but in al my years I have not found a bad power button yet. Always it has been the motherboard or the power supply.
