A user plans to use her laptop computer while she is traveling. She will be driving across the country and will not have access to a standard electrical outlet.
What should she do?
1. Purchase a Y-adapter.
2. Purchase a PCMCIA card.
3. Purchase a larger transformer.
4. >>Purchase a 12-volt power adapter.
Explanation : The user should purchase a 12-volt power adapter. A 12-volt power adapter can allow you to plug your laptop computer into an auxiliary power socket or the cigarette lighter in an automobile or into a power socket on an airplane. These adapters are often referred to as inverters.
A larger transformer will not solve the problem. The transformer (also known as the power brick) is located on the power cord. A larger transformer will not allow the battery to retain a charge longer. Also, a laptop must have a transformer with the correct power settings.
You should not purchase a Y-adapter. A Y-adapter is used to connect a keyboard and mouse to the same PS/2 port. It is not related to power.
You cannot purchase a PCMCIA card. A laptop does not receive power from the PCMCIA slot. Instead, a PCMCIA slot is used for peripherals, such as external drives, network adapters, or other peripherals.
