Disconnect all cables including power. Remove the battery from the bottom. Then hold the power button down for 20 seconds. Replace the battery and plug cables back in. reset the cmos if asked to don't save changes. You will probably need to reset your computer clock. This should work.
I tried your "holding the power button" suggestion but it didn't work. I still got no response to turning on the computer but a series of amber blinks (8 blinks with #2 and 8 lasting longer than the others) from the power light. Thanks for your suggestion.
i got this exact same problem. the amber power light flashes all night. when press the on button u her the hard drive start up but then it stumbles and switches off. nothing comes up on the screen it doesnt switch on. i will try the holding the power key trik above will report back tomorrow!
I had this problem, too, and found somewhere a tip that it is a loose video card - a known problem (among many others) with the SP 6100. All that needs to be done is to put the video card firmly back in its slot. It worked for me. Apparently where this problem is recognized the repair centers also add a device to fix it in its place permanently. Some repair centers, however, recommend a complete exchange of the motherboard, which is unnecessary.
I'm having the same problem as everyone else. I've tried the battery, checked the outlet voltage, pressed the on button for 20 seconds (with and without the battery, and the power supply). Also removed the extra memory that I had installed, and no luck. I suspect is the video card as mentioned in one of the replies above. Can someone give me brief instructions on how to get to it and check if the card is properly installed, or how to replace it myself? Thanks.
I had the excact problem your talking about and it was indeed the video card.
I just had to open the computer, take out the video card and put it back again.
If you need pictures, I can post them.
This is the way:
Unscrew all the screws under the computer, remove the small cover on the upper side of the keyboard and unscrew the two screws underneath. Lift up the keyboard and loosen the flat wide wire on the motherboard side. Loosen the two screws on the back of the computer. Open the small cover underneath the computer with the star screw and loosen the wire inside from the tape.
Now loosen the two wide flat cables running from the monitor into the video card, same locking mechanism as the keyboard.
You should now be able to totally remove the top cover including the monitor from the base of the computer. There should be two clips in front of the computer, use a flat screwdriver to loosen them. You can hear the click.
The Video card is the biggest card in the middle of the motherboard, unscrew 3 screws on this card and lift it straight up. Then you can put it firmly down on place again. Alternately you can look for some bended pins to make sure theres nothing else wrong.
Put everything together and start it up.
Helped for me!
OMG..you Rock dude....i followed your instructions to the letter and it worked. system is up and running...i even identified why i would occasionally would get the display blinking on and off....that was loose as well.
Thanks a million. The process took a little over an hour and it was tedious but worth it.
I had this problem 4 times and Toshiba Australia refused to get me a replacement because I bought it in the US.
I would be happy as long as the machine get fixed.
But this is 4th time and I can't live without computer!!!!
The machine is still with Toshiba and I hope this time they fix it permanently......
But I strongly doubt it.
I look for the cause and solution from web many time and I found the real cause and solution.
But it is a little different from video card problem mentioned here.
Actually, the problem is in the power supply/system board connector.
There also may be a problem in a video card problem.
I will try to fix the problem myself when my machine comes and break again.
I have a similar problem, except mine is a satellite 5105. I assumed the design would be very similar so i went ahead and started taking it apart to see if the video card was lose. I failed because i got lost in Tor's explanation:

> Lift up the keyboard and loosen the flat wide wire on the motherboard side.
> Loosen the two screws on the back of the computer
which two screws? Do you mean the bottom of the computer or the rear of it? Since I already removed all of the ones on the bottom i assume you mean the rear, but there are no screws there to be seen.

> Now loosen the two wide flat cables running from the monitor into the video card
I dont see these. Is this step supposed to come AFTER i "totally remove the top cover including the monitor from the base of the computer"? I tried this but it didnt come apart easily enough even with every screw removed... and i didnt want to break anything so i aborted the mission.
Yes, pics would be great please... or a guide directed to a 5-year-old.
The solution from Gert Westermann above worked for me but now the laptop (Toshiba SP 6100) is just looping while powering on. It just restarts over and over again. I have tried to boot from a winXP CD but nothing doing. Could someone please help me.
OK. I gave up waiting. I used the Toshiba recovery CDs to reinstall the OS. This involved reformatting the HD. I had to buy a tool called USB case so as to suck out all the data from the HD. Could someone please tell me how to go about filing a lawsuit against Toshiba? I am in Kenya, Africa.
Guess what? Apparently, Toshiba kept up the "great work" with their Tecra 8100's as well. I am getting the same problem...and now it is not even attempting to turn on. I tried taking out the hard drive, which worked before; I could at least see the BIOS screen. Now i see nothing, but the lights DO turn on when the hard drive is out. When the hard drive is in, amber light flashes in something like this: . . --___. . .___..--___.___, where "." represent short flash, "--" represents long flash, and "___" represents a pause in the blinking. I have pretty much ruled out the fact that it could be the hard drive, because I purchased a 40 gig brand new from Newegg.com, which failed to fix my problems, and was promptly returned to yield more frustration on my part. I suppose I will try reseating my video card (?) and power supply cable (?)...although I can tell you for sure that the little 20 second CMOS battery reset deal did nothing for me. What I can't believe is how Toshiba hires people that don't even speak english. They are too hard to understand, and just shoot me around their tech support hotlines, not one of them directly answering my pleas!
my toshiba has the same problem of you (sigh...), my toshiba seller told me that it is a problem about the internal alimentator and it is not possible repare it. Is it correct?
If I should know what is the model of the alimentator, i should try look for it on web and then buy and change the mine... Is it possible, you think?
thanks for your help
