Two flashing orange light in my toshiba laptop

[Thalecoyg]

hi im using Satellite L755..Recently my battery and the power adapter spoiled..It showed blinking orange light at this time..I then bought a new adapter and always use my laptop without any battery..My laptop was working fine with the new adapter. But this week, my laptop off-ed several time with flashing orange lights(im not using any battery)..I use to run my laptop with dual screen and a cooler pad..And when I plug off my dual screen and cooler pad, my laptop will run longer. At times, when I run graphics game like FIFA Online 3,it will turn of and flash orange light..But most of the time I can play this game..What might be the problem ?

Be sure the new power brick has the correct barrel and amperage!

maybe it is overheating. Are the vents dusty? try using a thermal monitoring software to see what temperatures you are at when running games

also make sure fans are spinning.
