Hi everyone - hoping someone might be able to help me with troubleshooting a non-boot behavior on my old Toshiba 410CDT. I've seen a couple threads relating to similar behavior on this series of machines, but none describes exactly what I'm encountering, so I'm hoping this new thread is okay.
Behavior is as follows: when I power on the system, both the power and battery/AC indicators light up green as expected, but after about two seconds, the Caps Lock indicator will also start to flash repeatedly and regularly (about one flash every two seconds, until the machine is powered off manually). The screen stays dark, and there's no beep indicating the computer has posted (I also don't get video if I hook the unit up to an external monitor while this is occurring). I've removed/reseated the main battery, expansion RAM module, hard drive, and internal CD-ROM drive, all without a change in behavior. The only thing that does change anything at all is removing the video board from its motherboard connector, at which point the Caps Lock indicator no longer flashes; I didn't know whether that was "something", so I swapped the video board for a different one out of a donor unit, but no change in the behavior there either.
I've done a cursory inspection of the motherboard and don't see any obvious electrical/component faults, nor do either of the MB batteries appear to have burst/leaked. As far as I can tell, everything is in the same condition it was in a couple months ago, when the machine was working just fine. And, as has been pointed out in the other threads, no mention is made of this "error code" in the maintenance manual, so I don't have any clue what it's trying to indicate.
Is anyone familiar with what might be going on here? Thanks!
