My Toshiba Satellite R10 suddenly stopped working. It's just past its warranty period, so no help from Tech-Support.

I can get no response from the battery (which was working fine earlier). I plugged it in to a NEW DC adapter and was not able to power it up. When I plug in the AC adapter the single AC LED light is green. When I try to turn on the computer the led changes to a flashing amber (yellow-orange) pattern. It gives four short blinks, one long blink, three short blinks. I understand that this may be a binary code (00001000) which may be converted to some hex code (h8).

I can do the work myself, but I cannot find out ANYWHERE what this code means. Please help!!!

Welcome to DAL;
Ok, you could try getting some support from them anyway.. unless you already have. After a little searching I found this;
http://www.hardwareanalysis.com/content/topic/51345/
It may be of use, good luck

Thanks. I found that site also, but all of the links are "forbidden". I found the cached pages from Google, but my code is missing from the list (from chapter 2).

Can't think of much else; you say new dc adapter? have you got any others you can try? any way of resetting the bios on the lappy or something?
