Not having the spec's or model of your gateway
I would look for a wire lead inside your case that would be coming from the front most are blk/red and marked pwr/led this could have worked itself lose off the pins on the motherboard.
Being I don't have the model gateway I can not tell you where the right jumper is or setting would be for it if it did come off. The other could be power supply or motherboard itself.

Word of caution: When working inside the computer wear static free strap and touch metal to ground yourself. Not to cause static inside around motherboard or any of the components insides.
This is only a speculation without knowing much about the model

Hello Jeff,

If your computer does the same problem after each cold start or every after sometime, that tells you that the power supply is working fine.

If so, well... check the CMOS Battery inside try replacing it must be 3V to maintain the BIOS settings of your computer. Also, clean the heat-sink of the processor if necessary to avoid overheating.

After that try to switch the computer ON. Post us back if there are problems, also don't forget to rate us so we could continue helping others.... good luck.

from Philippines.

Without a specific system designated I can only give a General answer.

On desktop/Tower systems, if there is NO POWER indication when attempting to turn on the system, the most likely point of failure is the power supply.

ATX power supply is about $30 and most are a one size fits all, but there are some variations in case design for low and high end systems

Gateway computer power light flashes before booting up.


Hmm. I wouldn't have thought it had anything to do with pressing the button. It sounds more like a failing power supply or lack of current for startup. Did you make sure you plugged the power into the video card power connector (if it has one)? I know it worked ok at first but a heavier load can cause older or under-rated power supplies to fail soon after. Just a thought.

Acer x3400 wont start up


Remove the Power Cord and then press and hold the power button for 30 seconds. After 30 seconds plug the power cord back in and press the power button. If it reboots you had a Static Charge Buildup and released it by holding the power button for 30 seconds.

When you press the power button do you hear the fan running, disk drives running, cd drive clicks once, anything on the lcd screen? If not I would think your Power Supply is bad and needs to be replaced.

It's either the Power Supply or Motherboard.

What causes red led on starting?


Remove Power Cord then press and hold the power button for 30 seconds, then put the cord back in and try to start it.

When you press the Power Button are you hearing the fans run, the disk drive running, the cd drive click and the light on it comes on for a second or two?

Anything shows up on the LCD Screen?

If you press the power button and absolutely nothing is happening then you most likely have a bad power supply.

If you press the power button and you start hearing beep sounds or blinking lights in a continuous pattern (ex. 1 long followed by 2 short) then you have a motherboard issue. Those beep sounds and blinking lights tells the technician what is going on with the computer.

I press my power button on and nothing comes on the screen. My screen is black as if it wasn't on. Please help me I have a Dell VOSTRO 1000


does a light come on when you press the power button? Remove the battery then just use the power adapter.Then check the cables of your power adapter if it is connected properly. Try unplugging and replugging the cable at the back of your laptop. Make sure that on the the power adapter ( the small rectangular boxlike) has a green light. Then try pressing the power button again.

I press the power button on the front and no fans run


Sounds like your power supply is not supplying 12v to the system. Check all your power connectors are seated properly on your motherboard, if so then i'm afraid you need a new power supply.

THe pc gives a steady orange light when power


Sounds like its in either standby or hibernate. Try unplugging it if it wont power on, press the power button, wait for 2 minutes then plugging it back in then turn it on. Afterwards, go into power managment, and find where it asks what do when you press your power button change from hibernate/standby to ask what to do.
