How to Fix Laptop Not Turning On

If your laptop has stopped turning on, you need to know how to fix it. The problem could be a faulty power supply, hardware, or software. Fortunately, the majority of problems are easily fixable with basic troubleshooting methods. The first step is to check the voltage on the power cord. If it is not a voltage issue, try to replace the CMOS battery and reset the BIOS settings.

Check for voltage at the end of the power cord.

If you have a laptop that isn’t turning on after plugging it into the wall, check for voltage at the end of the power cord. If there is no voltage, the laptop’s power supply is faulty. You can check the voltage with a multimeter. You can purchase one online or at Radio Shack.

Next, check the power adapter. The power adapter should have a plug and a pilot light. You should also check for any damaged insulation or warped or worn insulation. If the power adapter smells of burned plastic, it might be faulty. If all else fails, you can take it to a repair shop to have it tested. Once you have it checked, you can order a new adapter if necessary.

Replace the CMOS battery

The CMOS battery is located inside the motherboard. It must be replaced carefully, or it can cause severe damage. When removing the CMOS battery, do not damage the plastic casing. Replace the battery carefully and turn the laptop on to ensure it’s working correctly.

The CMOS battery is usually a CR2032 battery. It is attached to a metal clip with wires going into it. This is the only part holding it to the motherboard. Be sure to remove the clip and battery before replacing the battery. This may require some disassembling of the laptop. If this does not work, you can take it to a retail store to get a new one.

While the CMOS battery is a relatively inexpensive part of your laptop, it is essential to remember that it will drain over time. If left off, it won’t hold enough charge. If the CMOS battery has completely discharged, you may be able to jump-start it again, but it’s best to replace it sooner rather than later.

Restore the default BIOS settings

If you’re having trouble starting up your laptop, you may want to restore the default BIOS settings to fix the problem. The BIOS is the software stored on the motherboard chip and starts the operating system when the computer is switched on. This program will run a series of instructions to load the operating system. This process is similar to most computers.

If the storage drive causes the issue, you can disable it in the BIOS. This can help the system recognize the storage drive properly. You can also unplug any USB-powered peripherals, such as USB-powered mice. Unplugging them may also fix the booting problem.

To restore the default BIOS settings on a prebuilt computer, look for the manufacturer’s serial number on the case. If you can’t find the serial number, you can manually reset the BIOS settings on the motherboard. Usually, this is done by pressing F9 or F5 and selecting Yes to restore the default settings. Depending on the model, you may need to use different keys or menu options.
