When i tried to boot my computer it didnt boot up. I noticed that the green light on the on button was yellow. I tested my power supply and it seem to be bad. I purchased the correct power supply from gateway. As soon as I installed it it booted up right away. However it computer functioned for only 3 days. When I tried to boot he compueter today the powr button was yellow again as opposed to green. I can hear the fan to the processor working and the hard drive but the system wont boot. I cant believe that the power supply would fail after only 3 d ays.
Unplug the power from you 700xl and from you monitor. Try removing the cmos battery and reinstalling it. Then, plug everything back in and try restarting. If it continues to give you the yellow light, you may need to replace the CMOS battery, especially if it is more than two years old.
Another thing to consider is if your power supply is underpowered for the number of external devices you have plugged into it (i.e., cd, dvd, external hard drives, printers, pci cards, etc). Gateway installed very low powered power supplies in their 700xl desktop computers. Usually only around 250 watts maximum.
If you are replacing the power supply with another 250 watt maximum power supply, and you have a lot of external devices plugged in, you may need at least a 350 watt power supply....if your CMOS battery is not the problem.

Re: my gateway 700 xl doesnt boot
It seems you have a motherboard problem which is very common with gateway/emachine and the power supply issue. I hope your pc is under warrenty if not don't spend any more on that machine. Time to look for another or get a new motherboard.

i think you should replace the power supply or try another different just in case to be sure that theres nothing wrong...some times the computer doesnt come because of change in cmos configuration, clear cmos could help..if you dont have any experience doing it dont do it..and ask in fixya .com a i forgot you cant test unpluging all the drives just letting pluged the mother board cables and run a test...if it comes on b
You need to open your from its BIOS page. The way you can do this is to restart it and once it starts up press the delete button repeatly until your BIOS page comes up.. From here you have to change what your comptuer boots from. Change it to boot from CD DVD rom first then the harddrive. once you have this done save and quit the bios and pop in your cd.
Most newer models of Dell computers now
have a diagnostic LED surrounding the power button on the from of the
computer. When you press the power button to boot the PC, the light
should be green and remain green under normal circumstances. Any other
lights will help you troubleshoot the power issue you are having.
A solid green light
means the computer is operating normally. A solid yellow light indicates
the power supply is operating normally but the computer is not
processing data. This could mean there is a problem with the CPu or
another component on the motherboard. A blinking yellow light
indicates the power supply is receiving power from the wall, but not
functioning properly. This generally means the power supply itself is
bad and should be tested or replaced. A blinking green light means
the computer is in standby mode.
So use the LED power light codes if
your Dell computer has them. Also pay attention to any unusual beeps or
sounds coming from the computer.
Well, I was sure that the voltage selection switch was in the right
place. And I found it highly unlikely that the processor power cable
would suddenly unseat itself. Ugh.
Then I had an idea. I flipped off the surge protector and then
flipped it back on. Tada! No more orange lights. Weird. The moral of the story: try the simple stuff first.
I hope this helps and please dont forget to rate my answer. Thank you!
A LOT of Gateway computers will go into this catatonic state because of a dead battery. The battery is on the motherboard -- it looks like a metal disk about 1" in diamter. Check it or replace it. This applies to laptops too (not the actual laptop battery, the CMOS battery -- a laptop will have one on the motherboard too)
Try shorting the power pins on the Motherborad. (establish contact manual. use screw drivers such that they touch both the pins).
The power pins are the one the Start button are connected to. Remove this connection alone.
If this powers up the system, you would have to get the Button replaced. Else there's something wrong with the motherboard.
Kindly get back for any clarifcation.
You are on the right track. First, swap out the power supply. That normally is the issue. If that's not the issue, verify that the power switch indeed is working. You can do that by determining which color wires are for the power switch, then hold a multimeter set to resistance on the ends of those two wires. When the button is pressed, it should go to zero. If not, then the switch is fautly. That is an unlikely scenario, however. If the new power supply fails to work and the switch is okay then the problem is the motherboard.
sounds like something is drawing down on your 12 volt supply drives or on board regulators. Try it without the drives connectged, and see if you can get the system to boot up(you'll just get a notice that your drives are unavailable, but you'll already know that, right?
