Only an inspection of the plug-in area should be done. if possible remove the bottom cover and check the innards for any damage at that area. Excluding any s/w glitch, many times the physical plug-in connection is broken or about to be, as in loose. If the past battery was used too long it caused the charging ckt. to become "over-stressed" and it causing issues. Understand, on some newer batteries have a "smart ckt" to maintain battery readiness as for a charge and tells the adapter and mtrbd. to allow this action, this all depends on the design. Typically besides starting a charge it ALSO! tells it to stop charging. Overcharging or anything related to that can cause a battery failure or simply added heat to the laptop. All this isn't good for the long haul and falters in some way. Since a video port(int. video) can be stressed by added heat this in turn starts to falter, etc.. It maybe too late the damage is already done unless s/w related. All too often the mtrbd. has to exchanged or if small adapter plug-in, replaced if broken. Is that adapter plug-in loose?
For now, I exclude s/w issues. But, checking at the Toshiba support forum(website) see if similar issues aren't cropping up. You provided no Toshiba model#. It always helps to provide full details.

My Toshiba laptop has been having a variety of issues all involving the adapter. Replacement adapters have been tried as well as replacement batteries. Still resulting in same issue. I've gone as far as doing a system restore and resetting it to the factory settings.
When the laptop is turned on unplugged it has no issues. Once the laptop is on the adapter can then only be plugged in as long as some kind of video or game is running in the background. If not the screen will go black with multicolor stripes going through it that very much remind me of the matrix. Sometimes plugging it in will make it shut off entirely. I've even purchased a cooling pad and used canned air to clean the vents.
Is this issue in any way related to my display driver or video graphics? And is this something that I can fix on my own?
