Not sure if anyone has seen anything like this before- I have bought a second hand Toshiba Tecra 750cdm (a Pentium MMX 233mhz, 160mb RAM, 4gb HD, Yamaha OPL-SAx, S3 ViRGE MX) and after using it for about 4-5 hours nonstop, it powered off by itself when I was booting to the Ultimate Boot CD to run diagnostics for the HD (which is failing). Then after that, every time it powers on, it turns itself off after 13~ seconds.
I tried letting it be for a while, unplugged everything and still the same thing happens. Unplugged the hard drive and the CD drive, still happens. Even when I'm inside the BIOS setup, it still happens.
I'm guessing it is the power adapter, it's what makes most sense to me, as it is not overheating for sure.
I was going to try and tear it open but I couldn't find any service manual so I decided not to try and pry it open. Well, not for now at least 😀
