in simple terms as Brian Matthews suggested, attempt working a cable from someplace else. the subject right here sounds such as you're overloading a circuit. the subject right here is that there are too many stuff linked at as quickly as drawing greater potential than meant, despite in the event that they're at distinctive plugs and such, that is nonetheless one cable. an hassle-free math will answer issues right here. permit's in simple terms say that your cables are 12 Gage and the voltage is a hundred and twenty Volts. 12 X a hundred and twenty = 1440 Watts there's a thank you to come to a decision what plugs are interior the comparable line of the cord. Now, shall we are saying your Microwave takes a solid a million,000 watts, and you have a heater engaged on that comparable circuit, which will take a substantial quantity of wattage, making something circulate incorrect, like something shutting down. long tale short, you're drawing too lots from something which could not save up. decide your circuits at your place so which you would be able to locate the place issues are. as far as your laptop is going, the potential grant could constantly take care of the the remainder of the pc, yet on specific activities, there could be Motherboard harm or the different components. returned, I advise you do what Brian Matthews stated.
