Power supply and start up the computer

Hi there,
I got a Gateway Astro [all-in-one] from my friend. After I plug- in and switch-on, the computer does not start. It seems power is coimming to the copmuter but computer does not respond - no light, nothing. Even the keyboard does not light up.

Thanks,

Sharif

Here's the steps for troubleshooting Gateway systems that don't fully boot. It is based on BIOS beep codes which are beeps that occur when you first power the system up.

Sounds like a power supply failure, it sounds like your going to have it replaced.

Gateway blank screen


Here's some tricks I would try. Something here, might help...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your monitor on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
Good luck.

Gateway server 9510T


Check to be sure the power connector isn't loose on the back of the computer. If your plugged into a UPS be sure the UPS isn't switched off and the plug is completely in and the UPS is firmly plugged into the wall. If plugged into the wall be sure the plug is completely inserted.

If your still having no power open the side panel and be sure the power supply connectors to the motherboard are not loose, also check the plug from the power button to the motherboard to be sure its firmly seated.

If it still won't start call Gateway Tech support be sure you have all the docs for your computer handy, and your at the server when you call.

Computer will not power up


There may be a short on the motherboard. If the power supply senses something wrong they system will not boot up - unless you bypass the On switch.
I had a friend do this but he was building a system, he put all the standoffs in the case and the ones that didn't line up with the motherboard holes shorted components - he was fine until he bypassed the on switch.
Your system is a Gateway, so unless you have a screw rolling around in there (did you install a hard drive or something???) then the problem is something component failed.

Gateway computer 310 series wont power up when


It sounds to me like the power switch is plugged into the motherboard incorrectly. I would need to know the type of motherboard you have to get you the proper schematic for hooking up the power switch and reset switch to the board. If you have the manual to the motherboard, there should be a detailed picture showing you how it is to be hooked up. Please let me know the motherboard model for further assistance.

Good Luck,

Hpw do you replace the power source on a gateway MFATXPNT ESX 500S.


How do you know the power supply is the problem?
What issues are you experiencing?
Have you done any trouble shooting first? It could be a bad hard drive.

If you should need to replace the power supply first you need to get a replacement power supply for a gateway MFATXPNT ESX 500S - 300 watt power supply you can get here.

The next step is to unplug the computer from the wall > remove the case side access panel > ground yourself with an Anti-Static wrist strap cord so you don't fry *********** board electronics from static electricity discharge which can cost you a lot more to replace > now disconnect the plugs from the power supply wire harness, it may help to count the connections and mark them with a piece of tape or draw a diagram so you don't forget which loose cables should get reconnected to the new power supply. There will be at least one that connects directly to a plug on the mother board, DO NOT put tape there. > Next remove the screws which mount mount the power supply to the metal frame and slide out the power supply > slide the new power supply in the same way the other other was removed (note top from bottom) and then screw back to frame and reattach the cables > close the case > remove your grounded wrist band > plug computer back into wall and start the computer.

Congratulations, you have just replaced your power supply and ready to go.

IMPORTANT: Do not switch the power output selector switch on the power supply. Usually a recessed re switch which will adjust for european vs. US power input conversion.

Gateway 4016 will also not boot.


Certainly could...when all else fails check the case. I had an issue like this with my last computer. Turned out to be the case. A friend of mine had the same issue and his turned out to be the video card...it was drawing more power then his PS could handle. Either way it sounds like your on the right track.

I can already tell this isn't going to be an easy one. Let's try a few more things.
  1. Unplug the power supply from everything inside the PC. Leave it plugged into the AC cord. On the main motherboard (ATX) power connector, find the pin that goes to the green wire. Use a modified paperclip to short that pin to the next-door pin that should have a black wire. This should cause the power supply to turn on and you should hear its internal fan spin up. If not, this could be a sign the new power supply is also dead.
  2. Plug the power supply into only the motherboard and AC cord. Remove all unnecessary PCI cards and peripherals. Also, if the system has multiple RAM modules, remove all but one. This should leave the power supply, motherboard, video card (if it's not built in), CPU, and RAM as the only items connected. Power up the system and see if anything acts differently.
  3. If there are multiple RAM modules, try every different combination of modules and slots.
  4. I will ask this only because I've done it myself. In the swap between the old and new motherboards, did you verify there were no extra mounting stand-offs that might be touching something on the bottom side of the motherboard? If old and new motherboards are the exact same model, this shouldn't be an issue, but you never know.
  5. Verify there are no jumpers on the new motherboard that might need to be set for the front side bus, memory speed, etc.
  6. Ask your friends, family, and neighbors if anyone has a Pentium 4 in an LGA775 package that you could "borrow" to verify it's not your CPU causing the troubles.
