What does an inverter do in a laptop/notebook computer? An inverter changes direct current to alternating current. All computers use both AC (alternating current) and DC (direct current). On a laptop computer the devices that use AC current are the cooling fan, floppy drive, hard disk drive, CD-ROM or DVD drive and the backlight for the LCD panel.owever, laptops run on DC (battery) voltage. Therefore, the inverter is required to convert that DC to AC to light the backlight. In your case, the inverter probably is bad, especially if the laptop is relatively new, but the fluorescent backlight itself can also burn out.

Power supply unit (computer) While an ATX power supply is connected to the mains supply, it always provides a 5 V standby (5VSB) voltage so that the standby functions on the computer and certain peripherals are powered. ATX power supplies are turned on and off by a signal from the motherboard. They also provide a signal to the motherboard to indicate when the DC voltages are in spec, so that the computer is able to safely power up and boot. The most recent ATX PSU standard is version 2.31 of mid-2008.

Power Supply Since the power supply is the first place an electronic device receives electricity, it is also the most vulnerable to power surges and spikes. Therefore, power supplies are designed to handle fluctuations in electrical current and still provide a regulated or consistent power output.t receives power from an electrical outlet and converts the current from AC (alternating current) to DC (direct current), which is what the computer requires. It also regulates the voltage to an adequate amount, which allows the computer to run smoothly without overheating.
