Comp won't power on

Comp was plugged into surge protector box. comp was in standby. Also plugged into surge box was guitar amps and pedals, etc. being used at the time when surge box started making high-pitched sound - alarm? So turned off everything plugged into surge box EXCEPT for comp. Then turned surge box off and back on and discovered comp will not power on. No LED light, nothing! (Yes, everything else plugged into the box still goes on).
Have tried hint from Dell of unplugging comp and holding power button to discharge flea power and then plugging in comp directly to wall outlet. Still won't power on. Hope you can help! Thanks

Try unplugging the power cord from the PC and the wall outlet or whatever it's plugged into for a couple of minutes and then reconnect both ends. I've seen this fix a lot of PC's that wouldn't power up after a power fail.

Gerry is probably correct. Try it without the surge box, if that does not do it change the Power Supply. You zapped it with a petty big surge with all the noise etc. Run your computer on a seperate connection. The power amps can feed back via the power line. causing all kinds of problems in the computer.

It won 't turn on

check your power cords, check your outlets, check your surge protector, check the switch on the back of the pc. there may be a black toggle switch with a circle and a line, make sure it's flipped to the line side. if all that is normal, unplug the cord from the computer and open up the case. look at all your power plugs and make sure they're all secure, try and reseat the 1 or 2 main plugs, there should be a rectangular 12 pin plug and maybe a 4 pin plug. unplug them and then plug them back in. put the case back together plug it in, and give it a go. if still nothing then you have to troubleshoot whether the power supply is junk or if your motherboard died. we'll move on to that if it comes up. good luck!

My Gateway Essential 450 won't turn back on from the front power switch. Where can I buy a new switch or is the problem something else?

This is where you can buy a new ATX power on switch,

The Power On switch is located inside the plastic Power On button assembly.

Age plus the heat developed inside the computer, have made the plastic of the Power On button assembly, brittle.

I suggest removing the Power On button assembly from the Front Panel.

(And disconnect the Power On switch cable from the motherboard.
BEFORE you do I suggest you make a drawing, and possibly some notes, as to where that cable's wires plug into the motherboard)

Computer unplugged from power, follow Anti-Static Precautions.

I would suggest using a hairdryer set to low heat, and moving the nozzle slowly back, and forth at the plastic until it slightly softens.
(Or you can use a bowl of VERY warm water. The switch is no good now anyway)

Is the problem something else?
It's either a bad Power On switch, or a bad Power Supply.

(Provided you are sure the surge protector is getting power, AND you have ensured that THE receptacle in the surge protector that the computer is plugged into, has power.

I have had a few surge protectors where just THAT receptacle was bad. Surge protector power LED light was on. Monitor, printer, and router had power. Just ONE receptacle was bad)

There is a simple test to perform to see which component is bad Power On switch, or Power Supply.
IF you do not know how, and wish to, please state in a Comment.

Computer will not boot or anything

Does it have power? Have you tried hitting the F8 KEY repeatedly after the initial windows screen starts? Do any of the pc's lights come on (hard drive usage,lan,cap lock,num lock, etc)? If you have absolutely no power try another outlet, if your connected to a surge protector see if the surge protector reset has tripped (found on medium to expensive protectors - if you hve a inexpensive one you probably wont have a a reset on it) try to plug something else into the outlet like a lamp, if you have no power check your household circuit protector and reset the fuse, but of course be leery. If something tripped the circuit something isnt right, indicating a power surge. Storms in your area or construction nearby?

Dell speaker connection color code needed

  • *Turn off your Dell laptop.

    *Connect speakers to the speaker control box. The speaker control box varies depending on the speaker system you have. Two-speaker systems will have a female jack on the back of one speaker that you plug the other into the second speaker. If your system has a sub-woofer, all of the other speakers will plug into it. The connecting cords are color-coded to the jacks on the back of the control box.

    *Plug an audio cable into the "Audio-In" port on the back of the control box. If the audio cable is color-coded, it will be green.

    *Plug the other end of the audio cable into the headphone jack on your laptop.

    *Plug the speakers' power cord into a surge protector to protect your system from power surges. *Plug the surge protector into a wall outlet.

    *Turn on your speakers and set the volume at a medium level. Be prepared to turn the volume up or down after you turn your laptop on.

    *Turn on your laptop and confirm that sound is coming from your speakers.

    Thanks for rating

    Good luck

    It will not turn on please help me

    Hello, I will try my best to help you, ok? I need to ask you a couple of questions so I can understand your situation more clearly ok?
    1) Do you have your power cord plugged into a Power Strip or surge protector? If so, check and make sure that the switch is ON and/or the surge protector button has'nt been tripped.
    2) Is there any sign of power to the Power Supply Box that your power cord is plugged into? (ie: led light, or sound of the fan inside of the Power Supply Box?)
    3) Is the outlet that you are connected to live with power? (try plugging a lamp into the socket to make sure)

    After you have ruled out the above possibilities, let me know, and we will go from there, ok?

    My desktop dont come on

    1) Check THE receptacle in the surge protector the computer is plugged into.

    I have found more than once that One bad receptacle in the surge protector is bad.

    "Hmmm, surge protector power on light is lit." "Monitor has power, amp for the speakers has power, and the router has power."
    All plugged in to the same surge protector.

    Tried a table lamp into the receptacle the computer was plugged into, Nothing.
    Replace surge protector.

    2) Bypass the Soft Power On of the Power Supply, and see if the problem is the Power On switch, or the Power Supply.

    If you bypass the Soft Power On of the Power Supply, and the Power Supply comes on, the problem is a bad Power On switch.

    If you bypass the Soft Power On of the Power Supply, and the Power Supply does Not come on, the problem is the Power Supply.

    If you wish to know how to perform this simple test, just state so in a Comment.

    Last night I turned-off my PC througg Windows and when I pushed the power button this morning nothing hapened. There is no sign of "life" from the PC.

    Check the power source to the computer (both ends of the cord), if a surge protector is in line with the power , remove it and plug the computer straight into the wall. also check the wall plug with a lamp or something to ensure power there. make sure the switch on the power supply hasnt been changed to the 220v side.
    If no power at the wall- check your breaker box in the house
    If it works plugged straight into the wall- check the surge protector
    If power at the wall and plugged straight into the computer (no surge protector) and nothing lights up when you turn it on- have your power supply checked.

    Computer power won't turn on

    First thing to do is try to plug the pc in another wall socket to see if it goes on, If not, the MB could have gotten fried, even though the other plugs seem to work. Hopfully you just need another surge protector as that could have gotten damaged.

    HP M1050Y - not powering up after power surge

    The green light at back is probably the NIC or network interface card, which means the computer is receiving power. Just not enough apparently. Try changing the power cords from being plugged into the surge protector to being plugged dirctly into wall socket. When you do this take the ethernet cable out before turning it ON.
