  Toshiba 4100XCDT Won't Boot 
 Date Written 
Michael Riley Jul 01, 2005, 07:37am EDT Report Abuse
Recently I dismantled my laptop to fix the power socket on the back. After re-assembling it would not boot up and the only thing that does happens is the orange power L.E.D. at the front flashes and appears to be a series of long and short pulses as if it is a binary code producing an error code.
I have read some information from toshiba Technical Service & Support which states, and I quote :

"Toshiba Europe has identified that some notebooks manuafactured in January and February 2000 may have a fault that could prevent the notebook from starting up. This fault has been reported on some Celeron(tm) processor based Satellite 4090 systems operating at 400 MHz as well as Pentium(r) II processor based Satellite 4100 and Tecra 8000, operating at 400 MHz only.

Affected notebooks can no longer be started and the DC-IN LED at the front of the notebook blinks. Intel and toshiba have developed the solution to this issue that has been implemented in manufacturing (Intel revised up the module to REV 505) and any affected notebooks can be repaired relatively easily."

End of quote. [URL=]

If anyone can tell me what this repair solution is I would be very happy !!!

Having no response from my original posting I had no choice but to continual fault finding myself. Here is my suprise fix.
My first line of thought was that I had cased the fault myself when soldering the power connecter. To rule this out I would have to remove the mother board. I was not looking forward to that.
As I started to remove the heat sink assembly I noticed a board sanwiched between the heatsink and the mother board and it turns out that this was the processor card. Ths card plugs in to the mother board and it was loose because the heatsink had been assembled incorrectly. I plugged the card back in to the mother board and reassembled the heatsink and switched on. It all booted up immediadely and is working fine now.

This may help someone out there !!!

Hi, I have the same problem with the flashing led on a Toshiba satellite 4030CDT. Can you remember the sequence? Mine is short, long, short, short, long, long, long, short. I just replaced the LCD but I might have bugged up the processor while doing so. If its a processor error i'm getting i'll check it out. Do you know of a website that lists all the Toshiba led error codes if yours was different.
