What kind of power supply do laptops use?
Computers use multiple DC voltages, and the power adapter is the external part of the power supply for a laptop. The additional DC voltages are created by internal circuits. Desktop computer power supplies are in one internal unit, which converts AC to all DC voltages.
How do I know if my power supply or motherboard is bad?
Check the connection for each PSU cable running to the computer hardware component. Look inside the case for the motherboard light. Usually flashing lights on a motherboard indicate a faulty or misconnected power supply.
What is the average power supply on a laptop?
