Laptop shuts off when plugged in


Jan 31, 2016
My toshiba satellite c855 shuts off and restarts when the AC adaptor is plugged in. This happens mostly when gaming. If I use it on battery it won't shut off.

I cleaned and added new thermal paste, fan noise is good, CPU temps also good, I even tried new AC adaptor but still having the problem. Also updated Bios. Is a damaged power jack able to shut off the laptop? The only thing I could think of is this.

Please help me!!!! :(

I formated it, also took it to an electrician and they scanned software, so i don't think going to BIOS will change anything.
Thanks for your feedback though. (Even if i go to BIOS, i can't be sure because it shuts off randomly)
