Why is my Laptop not powering on?

If your laptop is not powering on, or does not turn on, there are several issues that might causing your laptop not to power on.

1. Power Adapter

If your laptop runs out of battery and it is not plugged in, it may not power on until you plug in the Power Adapter. 

Ensure that the laptop Power Adapter is plugged in on both ends correctly and securely. If your laptop works only with Power Adapter plugged in, then your laptop battery is dead or defective.

2. Battery

The laptop can also be in a power state that prevents it from booting. Disconnecting the power cable and then removing the battery from the laptop. Leave both disconnected from the laptop for at least a minute. Then, put the battery back into the laptop, connect the power cable, and try turning on the laptop.

Removing the battery on some laptop models could be tricky, you might have to remove the bottom cover to access the battery connector. Some laptop battery connectors can break off easily during disconnection from the motherboard.  

3. Residual Charge

Sometimes, a residual electrical charge can keep your laptop from turning on. You can think of it as an “electricity clog.” By performing the following steps, you effectively drain your laptop of any electricity and start over, which can result in it powering up.

1. Disconnect the AC adapter and remove the battery.
2. Hold down the power button for thirty seconds to drain any residual power in the laptop.
3. Without replacing the battery, plug the AC adapter back into the laptop.
4. Press the power button to turn on your laptop.
5. If the laptop powers on, shut down the laptop normally.
6. When the laptop is powered down, put the battery back in the laptop.
7. Power on the computer, and verify that it boots correctly.

4. Bad Hardware

If, after going through the suggested troubleshooting steps above your laptop still does not turn on, the problem is likely a hardware failure. The most likely hardware component to be at fault is the motherboard or processor. Unfortunately, more in-depth troubleshooting is required to determine the cause for the laptop not working. If faulty hardware is the root cause, repair or replacement of that hardware component may be necessary to fix the problem.

We recommend to contact PC Expert Services to have your laptop diagnosed and have them to replace the faulty hardware professionally.
