When I press the power button on my Lattitude D600, the power light comes on dimly, and I hear a light "clicking" sound for about three seconds, then it dies. I can't boot it up. I checked both the charger and battery, and they are fine. I'm thinking maybe the inverter has gone bad.

Re: D600 Power problem, Won't boot up
I agree. Try to turn on your computer using the ac adapter only. If the system won't hold power using the ac adapter. I suggest to call you computer manufacturer to check the warranty . I am seeing a problem with the motherboard.

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.Just because you see lights around the power button does not mean that the Power Supply is ok. I've seen many times when the Power Supply makes the light around the power button come on and makes the light on the motherboard come on, but it does not have enough power to make the Fan inside the power supply come on or anything else.

When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?
When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.
Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.
Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.
Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.
You need to be more specific and tell what happens when you plug in the power cord and press the power button. There are a number of reason why a computer will not boot, but if you tell what's going on someone can help you.
Computers don't boot for basically the following reasons, 1) the power supply is bad. That means when you plug it in you don't see any lights, and when you press the power button nothing happens, you hear no fans, no beeps, no blinking lights, no hard drive spinning, no cd drive clicking and nothing appears on the lcd screen.
2) A motherboard issue, usually when this happens you will either see blinking lights or hear beeps. Those blinking lights and beeps are codes that tell the technician what is really going on.
3) Static Buildup - try removing the battery and the power cord then Press and Hold the Power Button for 30 seconds. After 30 seconds put the power cord back in (leave the battery out) and Press the Power Button. If it boots up you had static buildup and can replace the battery, count your blessings and Thank The Lord cuz a dishonest repairman would have told you he had to replace the motherboard for $300
When you press the power button do you hear the fan running, hear the disk drive running, see any lights, do you hear the cd drive click once and see the light come on briefly on the cd drive door? If you see all the aforementioned then it is surely trying to boot. Computers don't boot mainly because of the following problems. 1) Bad Power Cord or Power Supply. 2) Electro Static Buildup. 3) Bad Motherboard 4) Bad boot or system files. Remove the Power Cord and the battery if it's a laptop. Press and Hold the Power Button for 30 Seconds. Then replace only the Power Cord and try hitting the Power Button. If it boots you had an Electro Static Buildup. If you have boot or system files that are missing or corrupt normally the system will be telling you that on an error message that appears on the screen. Does your system show you anything on the screen when you press the Power Button? If not you have a Power Supply or Motherboard issue.
I am sure Not the CPU or fan problem. Follow the below step to repair it.
1. Just press the power button 5 seconds or more to see the laptop can reboot or not.
2. replug the memory modules.
3. maybe the power supply device failed that the electronic volt is not enough to boot the laptop. Just replace a new Dell latitude d600 battery power supply.
Okay, I had that problem with my HP less than a minute ago.
Maybe it is the same problem. See if the battery light comes on. Press the power button again and again if it doesn't start, for some time. It may show the boot screen and hang. Now, the battery must be charged. Shut it down directly and switch the AC off.
Now, switch it on and see if the battery light comes on. If it does, it is the same problem as mine. Now, turn the PC over and remove the battery carefully. There may be switches for that.
Now, plug in the AC and start it without the battery in. If it does, you're done. Now, plug in the battery again.
