My laptop freezes when I connect the power cord, works well on battery
only.

I want to check the motherbard in search for the faulty component,
where could I find pinouts and voltages to check for?

I don't know about acquiring a schematic for trouble shooting the MB,
but the first thing I would do is test the power adapter with a load
attached. I have repaired several that output the correct voltage but
failed to regulate when loaded down.

Also, some Toshiba Satellite computers were notorious for having power
connector problems. I trust this computer does NOT have such a problem?

no problems on the connector
tried different power supplies, even stabilized laboratory psu

Did you try cleaning the air ducts? When on batter the CPU 'may' be at a
reduced clock speed via Toshiba Power Management when on battery. When on
the PSU, the CPU will go to full speed and may just be over heating.

thank you, anyway please consider the laptop is completely teared a
part, non problems of air flow, and when connectinh power it locks
immediately even if in the BIOS pages
