George reports that his laptop will not power up. He says that he received a warning that the battery was low before the computer powered off. The laptop was plugged in to a wall socket. You plug the laptop into a different wall socket and no power light comes on.
What should you try next?
1. Plug in the computer using a working AC adapter with higher voltage.
2. >>Plug in the computer using a working AC adapter with the same amperage and voltage.
3. Remove the battery and plug in the computer using the same AC adapter.
4. Plug in the computer using a working AC adapter with higher amperage.
Explanation : The problem is most likely caused by a faulty AC adapter because the battery did not charge even though the adapter was plugged into the electrical socket and the laptop did not power up when you tried a different electrical socket. If the AC adapter was working, when you plugged it into a different socket, the light would be a solid alternate color to indicate that the battery was being charged. A laptop's AC adapter has a specific amperage and voltage that must be matched. If the amperage and voltage do not match, you could damage the circuit board.
You should not remove the battery and plug in the computer using the same AC adapter. The problem is most likely the AC adapter. Also, some laptops will not power up when the battery is removed because the battery is necessary to complete the circuit.
You should not plug in the laptop using an AC adapter with higher voltage. The AC adapter must have the same voltage as the one that shipped with the laptop.
You should not plug in the laptop using an AC adapter with higher amperage. The AC adapter must have the same amperage as the one that shipped with the laptop.
