Hello my name is abbaty from Nigeria i buy a toshiba c55d-b5310 AMD A8 from a company called Darodaz, i have been using it for the past 1 year and it’s one of my best laptop i have ever buy and use, best for my work. so one day i try to (power on) the laptop, it does’nt on. when i press the power button a white light shows and stay on but the system will not show, meaning the fan will not work, the screen will not display and that is how its stay. so i take it to one of my friend that repair computers, he figure out the problem is from an IC label U2, the IC is burnt so he replace it with another one, but it does not solve the problem the IC is hot when he power the computer, so please i need an advise and if you can help to find a way that i can buy the IC to replace it with i could like it more. i really love my toshiba. Thanks you. my email: abbaty48@gmail.com

Try plugging in the power cord and restarting it. You also might have a clogged fan. You can also try starting it in Safe Mode by pressing the power button and then quickly and repeatedly pressing the F8 button.
