Not turn on


Unplug all power cables and check for bad connections. Reconnect all cables. Does the power supply fan rotate? Yes or No? Looking through the vented left side of the tower with the power cable plugged in do you see an LED lit? If no fan spinning in the power supply and no LED lit, then I suggest you change the power supply. Either do it yourself (very easy to do or have a tech shop do it for you - it's cheaper to do it yourself).

1. Un-plug all power cables.
2. Unscrew side panels.
3. Count how many of each type of power cable is required for on board devices.
4. Calculate power requirements by watts.
5. Purchase new power supply that has the cables you require and the required wattage to support your devices.
6. Unplug all power cables inside.
7. Plug in new power supply.
8. Plug in power cable first before turning on the computer. The green LED on the motherboard should come on. Congrats you have power.
9. Turn on the computer.
10. Enjoy!

Plug into outlut but screen and power buttons dont light and dvd player doesnt work


Do you get any indication that the laptop is trying to boot - do you have a Power LED that is lit, any other LED indicators that flash at all?Have you tried to connect the laptop to an external monitor and if so, do you get any error or progress messages shown on that display?If the laptop will not power on at all, then try removing the battery then plug back in the power supply and see if it will boot with the battery pack removed.

Gateway 503gr has no power, the standby light flashes green when I remove power. Tried new PS and the standby LED stays lit. I then tried both new and old PS disconnected from board and shorted...


Disconnect everything from the motherboard except the power supply connections and cpu fan. Install one stick of RAM and connect your monitor. Then try starting up. See if you get any BIOS boot messages. This will tell you that the board and processor are okay.

With what you say you've tried already, I'm thinking you might have a bad processor. Most every other problem would result in some kind of error like POST beep codes or messages on screen. If the system still doesn't boot with the bare minimum parts installed, replace the processor.

Normal shut down on pc, now it will not power up.


if you can figure out what pins your power switch is plugged into you can try and bypass the switch as for the power supply itself i know theres a way to trick it and boot just the power supply but i cant remember what pins on the plug it is try and google the power plug layout it should tell you what pins to connect to boot it

Dell dimension 2400 blinking amber light


1. Remove All External Devices
2. Check the Computer's Power LED
3. If the power LED has not changed unplug the Power Cable From the Computer Disconnect All Hard Drive Power and Data Cables and power on the computer. If still no go.
4. Remove All PCI, PCI-E, and AGP Expansion Cards .
5. Remove All Memory From the Computer
6. Reseat the ATX and 12-Volt Connections . The ATX connector will be a 4 pin square connector connecting to the motherboard from the power supply and the 12-Volt Connection would be the biggest connector with a lot of colored wires.
7. If still no go.
8. Disconnect the Power Connection to the Chassis Fan
9. If the light still flashes then it could be a power supply or motherboard failure. Try a good know power supply first and if that does not fix the problem it is the motherboard. Also check the back of the tower for 4 lights lables ABCD or 1234.
Rate if useful.

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.

Front panel Ac Switch failing to start computer.


Try these steps.
If Power supply light does not turn on (or no power supply LED)
Perform the following steps, in order, until power is restored or it is determined that there is a hardware failure:
NOTE: If the Power Supply fan spins when the PC is turned on but the light does not come on, it is possible the LED is defective. If this is the case, use the section Power supply light comes on or flashes .
1. Disconnect everything from the PC, including the power cord.
2. With the power cord disconnected, press the power button on the front of the computer. Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
3. Replace the power cord with another power cord, like the one used by the monitor.
Test to see if the computer can turn on. If not, continue using these steps.
4. Ensure that the voltage selector switch is on the correct setting, 115V for North America.
5. With the power cord removed, flip the red voltage selector switch to the opposite position, wait about five seconds, and then switch the red voltage selector switch back to its original location.
This ensures that the voltage switch is engaged and set correctly for your country/region.
6. Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
7. Plug a lamp into the same outlet to see if the wall outlet has power. Try the computer in a different outlet in order to eliminate the outlet as a possible source of the issue. Test both to see if the wall outlets have power.
8. Remove all extension cords, power strips, surge protectors and any converters that remove ground. Plug the power cable directly to the wall outlet. Test for power. If this fixes the issue, find the device that is causing the issue and do not use it.
9. Use a vacuum cleaner to remove the build-up of dust from the power supply fan vent holes. Make sure that the PC is turned off and that the power cord is plugged into a grounded outlet. Only use the end of the vacuum hose near the outside of the fan entrance.
Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
10. If all of the above steps have been tried and the power supply light remains off, use the steps in the next section, use the next section Power supply light comes on or flashes , to reseat the cables and check the power switch connector.
