Question:

What could be the cause of a laptop not powering on despite having a new battery and a working charger?

I have a four-year-old Acer Predator Helios 300 Model: PH315-52-710B running Windows 10. A few days ago, I woke it up from sleep mode and the screen remained black. I had to force a shut down and then it refused to turn on again. This issue occurred sporadically in the past month but it always resolved itself eventually. The charging indicator light is blue when plugged in.

I have tried the following troubleshooting steps without success:

• Disconnecting the battery and holding the power button for a few seconds before reconnecting it and trying to turn it on.
• Removing the battery and plugging in the charger only and trying to turn it on.
• Draining the battery completely and recharging it fully and trying to turn it on.
• Replacing the battery with a new one from Acer and trying to turn it on.

The

charger has been tested and confirmed to be working properly. I am at a loss as to what could be the problem and how to fix it. Any expert advice would be greatly appreciated.

Answer:

If your laptop is plugged in but not turning on, you may be facing one of several possible problems. The most common causes are a faulty power supply, a broken power jack, a damaged motherboard, or a corrupted BIOS. In this article, we will explain how to diagnose and fix each of these issues.

Power Supply

The power supply is the device that converts the AC current from the wall outlet to the DC current that your laptop needs. It consists of a power brick and a power cord that connects to your laptop’s power jack. If the power supply is defective, it may not provide enough power to your laptop or it may damage your laptop’s components.

To check if your power supply is working properly, you can use a multimeter to measure the voltage and current output of the power brick. You can also try using a different power cord or a different power brick that is compatible with your laptop model. If you find that your power supply is faulty, you will need to replace it with a new one.

Power Jack

The power jack is the port on your laptop where you plug in the power cord. It is connected to the motherboard by a cable or a wire. If the power jack is loose, broken, or short-circuited, it may not deliver power to your laptop or it may cause a short circuit on the motherboard.

To check if your power jack is the problem, you can wiggle the power cord while it is plugged in and see if the charging indicator light flickers or goes off. You can also inspect the power jack for any signs of physical damage, such as cracks, bends, or burns. If you find that your power jack is damaged, you will need to replace it or have it repaired by a professional.

Motherboard

The motherboard is the main circuit board of your laptop that contains the CPU, RAM, BIOS, and other components. It is responsible for managing the power flow and the communication between the hardware and the software. If the motherboard is damaged, it may prevent your laptop from turning on or it may cause your laptop to malfunction.

To check if your motherboard is the problem, you can try to reset the BIOS by removing the CMOS battery for a few minutes and then putting it back in. The CMOS battery is a small coin-shaped battery that stores the BIOS settings and the system clock. You can also try to reseat the RAM modules by removing them and then inserting them back into their slots. If you find that your motherboard is damaged, you will need to replace it or have it repaired by a professional.

BIOS

The BIOS (Basic Input/Output System) is a firmware that controls the boot process and the hardware settings of your laptop. It is stored in a chip on the motherboard and can be updated or corrupted by software or power issues. If the BIOS is corrupted, it may prevent your laptop from turning on or it may cause your laptop to display an error message.

To check if your BIOS is the problem, you can try to access the BIOS setup menu by pressing a certain key (usually F2, F10, or Del) when you turn on your laptop. If you can access the BIOS setup menu, you can try to restore the default settings or update the BIOS to the latest version. If you cannot access the BIOS setup menu or if the BIOS update fails, you will need to flash the BIOS using a USB drive or a CD-ROM.

Conclusion

In summary, there are four possible causes of a laptop not powering on despite having a new battery and a working charger: a faulty power supply, a broken power jack, a damaged motherboard, or a corrupted BIOS. To fix each of these issues, you will need to either replace or repair the faulty component or update or flash the BIOS. We hope this article has helped you to diagnose and solve your laptop problem.
