The battery was going dead, so i plugged in the cord, and everything went black. just ... poof. dead. no lights. nothing. the light on the adapter was on, so power coming through. did I blow a fuse? is there a fuse that can be reset? or did I blow the power system somehow?

1. Remove all USB devices such as printers, mp3 players etc etc.
2. Remove the power-cable and the battery
3. Press and hold the power button for 30 seconds
4. Put the power-cable back in but not the battery and none the USB devices.
5. Turn the computer on
If this doesnt work can you hear any fans or hard disk activity when you press the power button?

I have the same problem. What I have found with mine is that if I can get the battery to take just a little charge then I can get it up and running. Here is how I do it. Disconnect AC power leave the battery in and start the laptop. As soon as thing start to run I plug the AC back in and it works fine from there on. Now mine is flashing as well now and I have a dead battery and it will not restart. Something I have noticed thought is it appears that the yellow light is blinking a code. This is what I have come up with. I appears to be flashing 323 as the code or could be 2 shorts 1 long then 2 shorts and then 3 shorts.
Anyone know where to find info on these flashing codes.
Thanks

Heres the fix:
This requires access to the cpu and heatsink, remove the keyboard and palmrest to access the motherboard, I think you have to remove the screen too. Remove the heatsink and cpu. Reseat the cpu, heres the kicker, press firmly on the center of the cpu while turning the locking screw. Pressing the cpu hard, allows the locking mechinism to get a good bite. Turn the locking screw hard into the end of the turn. Hook up the heatsink and set it back on top of the cpu. Press down on the heatsink over the cpu, fairly strong pressure.
Now test the motherboard, use just cpu, heatsink, memory, power button board and cable and external monitor, you can use your screen instead by just hooking up the cable to motherboard, leave the screen laying flat on the table. Now push the power button with one hand and the other is still applying pressure to the heatsink, no you dont need to screw it down yet. Keep reseating the cpu with varying degrees of pressure if you dont get it go the first time.
The trick will be to get it all assembled with the same results.
There seems to be a problem with the cpu seating correctly, it must come loose and the laptops exhibit the symtoms of no video. It might even be neccessary to insert a wafer thin piece of copper or something in between the cpu and heatsink if the heatsink doesnt apply enough pressure to cpu to keep it seated deep enough to run the computer.

have you tried either switching between external and internal monitor usally Fn + F5 on toshiba or try plugging a monitor into the back and see if it displays.
if you get a display on the external monitor then its probably a screen or inverter fault if you donot get a display to an external screen then it is likley t be the graphics on the board itself.
hope this helps
