Here is exactly what happened. I was coping a video to my laptop from my flash drive. Then suddenly my laptop turned off. If you look closely you will see three lights(look at the arrow) on the front of the laptop. usually those lights are always on, as long as the laptop is not been shut off. Now when i press the power button those ligths won't stay on, they only flash, and neither will the computer. I did have the laptop on my bed, but now i moved it to a flat surface. it was not overheated and it is pluged in.

Re: Laptop won't turn on
I have noticed sometimes with my D600 that happened once to me scared the heck out of me because I was doing the same thing as you where, What I did was shut everything down on my 600 and then removed the battery the hard drive and any other drives, then took out the memory modules and after everything was out of my D600 I truned it back over and pushed the start button and held it for 10 seconds with NO POWER ON, after that I replaced My memory mods frist then the HD then The dvd,last but not least my battery. Hit the power button on thank the computer gods It turned back on and has been working ever since, My opinion was It was the Memory Modules Had got loose somehow But Its been working great ever since. So I hope It helps you, Let Me Know Thanks Bear001

You say the battery is charging? Have you tried another Cord/Charger with the EXACT same power specs? Has the AC jack been damaged due to pulling on the cord while plugged in? Any damage? Drop? Do you leave the Laptop plugged in while not in use?
so easy, u need to download a software called WinToFlash, that will solve the problem, after coping the windows usin that software on ur flash drive, u may need to do a bios setup if F12 didn't work to start the laptop from a USB DRIVE . GOOD LUCK
The problem is most likely in the DC jack in the laptop, "common issue" the laptop must be dismantled down to the motherboard level, chances are the main board must be removed from the bottom chassis and flipped over to expose the solder joints underneath the DC jack and a resolder touch up done.
you connect the external monitor & nothing is displayed on it, then
this means that both the backlight lamp & the inverter board are
fine. The main indicators in these cases are the sound, and the hard
drive LED on the laptop case. If the laptop sounds just like it always
does for a minute or two after being turned on, it means it's going
ahead and booting the operating system, but the video processor or part
of the motherboard circuit for video output has failed. If the laptop
just sits there and beeps when you turn it on, or if you hear the fan
but not the hard drive chuckling with its active LED flashing away, it
means the laptop isn't getting as far as trying to boot the operating
system. While this could be due to any number of hardware problems, the
most common and easiest to troubleshoot or repair is RAM failure. If
your laptop has two RAM modules installed, try booting with just one
and then the other in the primary slot. If your laptop only has one RAM
module, you might consider buying one online from a site with a good
memory selector, like Crucial.com
Start taking your laptop apart piece by piece and test it after each removed component: 1. Remove the hard drive and test the laptop. 2. Remove the DVD drive and test the laptop. 3. Remove the wireless card and test the laptop. 4. Unplug the display panel from the motherboard/video card and test the laptop. etc.... Continue taking it apart until you have only three major components connected: motherboard (with video card), processor, and memory. If you still experience the same problem, most likely it's bad motherboard. By the way, before you start, try reconnecting the memory module. If you have two modules installed, try removing them one by one and test the laptop with each one separately

the hard drive is definitely bad so take it out of the laptop, clicking noise means the platters inside of it are misaligned.
After taking out the hard drive then turn on the laptop and see if you get video. If you do then you know the hard drive was shorting out the motherboard. If you still don't get video then unseat and reseat the memory sticks one stick at a time in each slot one at a time and try turning it on after each memory reseat.
If the laptop still doesn't turn on then take out the dvd drive as well.
If you still have no video then that means not only is the hard drive bad but also the motherboard.
I think it might be the motherboard, if its not regulating the voltage properly then to much will go thru the motherboard and the fan won't be able to cool things down properly. Eventually then the motherboard will fail and then no video like your having now.
Try these steps anyway just to be sure:
only hook up the AC Adapter keep the battery disconnected. See if it turns on, if you still get a blinking green light then go ahead and turn the laptop off.
At this point, unseat and reseat the memory one stick at a time in each slot one at a time. Try turning on the laptop after each stick reinsertion.
If that doesn't do it then disconnect the hard drive and the dvd drive from the laptop.
Then try turning on the laptop, if you still can't get video then the motherboard is bad and would need to be replaced.
