Laptop Power Problem

"No matter what you do, you can't get your laptop to turn on."

Faulty charger connection

The reason that the laptop does not turn on is that the charger is not functioning

properly. It could be that the wires inside the charger may be broken or the jack that connects the charger to the laptop has been broken. Another cause is that maybe the connection between the charger port and the motherboard has been broken. In order to determine where the connection is broken, you need a digital multimeter to test where the wires have broken connection.

Faulty Battery

Before taking off the backing or bottom of your laptop, plug into charger and make sure it is charged. Another cause of a faulty battery may be an indicator that your battery needs to be replaced. Make sure to note the exact battery model and replace the battery. Also, make sure that the battery is properly connected to the laptop if you have replaced your previous battery.

Bad display

The tablet portion of the laptop may have a bad screen so consider replacing the screen. Also, consider checking the status of the graphics cards to ensure that they are compatible with the display status settings. If that is the case then consider upgrading the graphics cards.

Bad logic board

Overall, the laptop's logic board may have a problem receiving or transmitting power. Consider replacing the motherboard to a newer, compatible model if it is the situation. Otherwise, determine which part in the logic board is having problems that hinders its operation. Consider replacing that specific part of the logic board.

BIOS problem
