With the charger plugged into the lap top, but NOT connected to the mains, the laptop functions properly. If you plug the power supply into the mains, the laptop goes stupid and hangs up. IF that's the case, I would suspect that something is wrong with the charging supply. Such as the voltage is way high, causing the laptop top get annoyed and hang up. Have you measured the charger output with no load on it?

I measured the voltage and it's normal, tried several chargers anyway

I have plain Windows 7 installed at the moment, no Toshiba nor other utilities, even never connected to the network. Anyway it freezes even in the BIOS when connecting power.

Since the unit seems to be locking, the driver software could be most likely is the issue and maybe proprietary to that lap top Things like this happen after a Windows update, unexpected error on the HD, some one removed something they shouldn't of or, a funny program is running on board.. It's possible a bad onboard support circuit but I doubt that very much. A simple test to prove this would be to boot to bias so the basics of the machine is on and energize the charger to see if a lock takes place there. Next, boot into safe mode, and try the same thing.. If all is ok up to this point. correct the software on board. Have a good day. P.S. some Laptops have a partition on the HD that has special set up software at boot time to configure the proprietary onboard chips.. This also could be an issue..
