My Dell dimension 8200 will not power up when I hit the power button.
I did check and there is pwer to the mother board, I know this because the LED light on the mother board is on.
Try a new power button. Also does the machine power light turn on at the front of the machine? if so check that the CPU is seated correctly as if it has come out of position then the machine doesn't boot. I would like to think power switch though.
Thanks J
Not to worry the CPU is located under the small fan and heat sync on the main board. To access the power switch take both sides of the computer off and at the front of the machine(Inside) you may see some plastic lugs just unclip those and the front comes away the you will be able to access the power switch. But before this check that the power switch or the reset switch are not stuck in. You can free them by spraying anti static cleaner over them and letting it soak for a few seconds then press them a couple of times then clean them off and try powering up then. It is best to do this with out the power cord plugged in.
Thanks J

Elleth,
It's very possible that your power supply has gone bad. A friend of mine brought me a Dimension 8200 to look at a few months ago that was acting exactly like yours. At first glance, I assumed that the power supply was ok because the LED on the motherboard was lit up. I decided to check the power supply with a tester and found out that the only live lead was the +5 VSB (5 volt stand by) which explains the LED being on. I replaced the factory 250 watt power supply with a 350 watt and it happily booted up. Keep in mind though that you may need to make a slight modification in order to use a non-Dell power supply. I had to make the opening in the back of the case slightly larger so I could plug the power cord into the power supply.
Good luck,
Mark

Thanks for the quick response!
When the problem first started there was an orange flashing light on the power button if I held it down for a time,now nothing. CPU? Where is that? I have the machine open, but I'm not sure how to access the power button? (Sorry for the stupid questions).
Thanks!
I have the same problem, the green led is showing on the motherboard. I tried replacing the powersupply with the exact same results. My question is: once I pulled the casing away and was able to access the poser button assembly, I found that it is a curcuit boad and ribbon type instead of just a standard power button. How in the heck do you get this off, assuming that I can even find another one that is...I noticed that this seems to be a common problem with this 8200 model after reading all the posts here on fixya...any help? Thanx a bunch in advance
same ****!
Dimension 8200 will not turn on after a power down. If the light at the power button is on or flashing, it will start after a few tries but now no light at the power button and it will not turn on. is it the power button or the power supply or something else? can i test any or it?
