YouTube videos only play on unplugged Toshiba - dark otherwise

Toshiba laptop. Videos from YouTube go black unless it is unplugged...user has upgraded the drivers. Any idea what could cause this and how it can be remedied. Thank you.

Try with this. Or you can tell us which graphic card are we talking about.

Hello There

Which drivers? Chipset drivers? Video drivers? Start with that. Check the compatibility of these drivers if the laptop is older.
Is there any power management tool installed?

Try to change the power plan to High Performance.

Most Toshiba laptops have 2 graphics cards. One could be NVIDIA which is a higher performance, the other one an Intel card. The Intel card is usually more energy efficient so that is most likely the default when the laptop is not plugged in, the secondary card, is usually the higher performance card. This Card is most likely utilized when the laptop is plugged in. This would explain the two separate responses when plugged in and not plugged in.

This however is just an educated guess at the moment as we do not have any information on the model or the exact errors.

It's a Toshiba L-50D-B-179. I've attached a video that shows what happens..
