Hello. So my laptop is acting very strangely. It started with turning itself off and the blue screen of death appeard but then it would try to restart itself but the screen was black. Then I started having problems turning it on, it powers on but the screen is black. But after a few tries a managed to turn it on, although it turned off after a while. I tried to auto recover and managed to backup my data on the safe mode and it didn't turn off itself although the auto repair didn't work. I thought there was a malware and I reinstalled it. I installed Ubuntu. It worked but then I turned it off and when I tried to turn it back on it worked but then it turned off itself and I haven't been able to turn it back on. Although I just tried one more time and it surprisingly worke but it turned off again. Also there is that weird light under the F11 key. And whenever the light is on, the screen is black. If i manage to turn it on, the light is off. My laptop is Toshiba Tecra S. Hope someone can help.
