Dell T3500 Power button blinks yellow 3-5 times and the 1 and 3 numbered lights blink as well - then they go off together and computer will not turn on

you need to talk to the person that programmed it

An amber light means your computer isn't reading the hard drive or CD right, Take it to a professional to get this corrected

wait for the light to go out then press power. Then if it doesnt power up hold the menu and the Device/input buttons on the set both in together for 5 seconds the light will blink a series of blinks pause briefly then blink another number of blinks then pause then it will repeat the same two digit blink sequence a few times . Let me know the two digit blink sequence.

How many blinks? Count and notice the patterns of the blinks (3 long blinks or 1 long blink followed by two short blinks).

Remove the Power Cord, Open the Case and remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.If all the above fails, you problem could be your Video Card or a motherboard issue.

Try running diagnostic test press the power and the windows key at the same time and it will run in diagnostic mode and hopefully that will reveal the trouble. Also, you may wish to try reseating the memory.

the continuously blinking yellow litght indicates that the power supply gets juice from the line but cannot distribute powe to the components. the first thing to do is to check and see if the power supply is working. dell power supplys have a test button, if you turn the computer around and hold the button on the power supply down for a few seconds the light should turn green, if it dosen't then you need a new power supply. if the power supply is ok, turn the computer on and have a look at the diagnostic lights (on the back, labeled 123 and 4) if you call the dell support line and tell them your model number (or give them the service tag) and which of those lights are on they will be able to tell you what the problem is. if you are still in warranty they will fix you, if not they will direct you to someone who can.
