Reconnect the power cord, wait thirty seconds, and then power up the computer. If your laptop powers on, remove the battery and replace it. Reinstalling the battery may not get the laptop up and running, so you’ll need to buy a new one. Having a laptop that won’t boot up can be a nightmare. Work, photos, and documents could all be lost if you don’t take precautions. Even while it may be frightening, there are often simple solutions to have your laptop running again.
Cause of Laptop Not Turning On
There are several possible reasons why a laptop won’t turn on. Laptop screen, battery, and power adapter issues are among the most common causes of laptop malfunctions.
How to Fix It When Your Laptop Won’t Turn On
You should start with the most likely and easiest-to-fix causes of a laptop not turning on and work up to the more challenging ones.
Change the power supply if necessary. This may seem obvious sense, but make sure you haven’t connected your laptop to the wrong power supply. The majority of laptop AC adapters are the same in appearance. Your laptop won’t work if the adapter doesn’t provide the appropriate voltage and amperage.
In other words, if your laptop’s power light is on, the power source is likely operating. An issue with the laptop’s battery may be indicated if both the laptop’s light turns and the adapter’s power light are on.
What happens to the battery when you’re not using it? We’ve been found without a fully charged battery at least once in the past. The screen should not be the culprit here. When the screen is black, it’s easy to assume your laptop is shutting down, but that’s not always the case.
Start by increasing the volume on any external display you’ve connected to. Remove the extra display and see if your desktop shows on the laptop’s primary screen instead. To brighten the screen, use the brightness function key on your keyboard. To determine if the issue is specific to your laptop’s display, connect various external monitors to your laptop’s HDMI or other visual output port.
If nothing appears on your laptop’s display or monitors but the power and/or keyboard keys, your laptop’s display adapter may be malfunctioning. A computer specialist would be required to replace the adapter in this instance. Discard any media capable of starting a computer. A USB stick or DVD could create starting issues if you’ve used them to launch your laptop and then forgot about them. Leave all docking stations behind. When you try to start your laptop with a docking station with a malfunctioning power port or power supply, problems can occur.
The power adapter must be connected directly to the laptop, not the docking station. The docking station must be replaced if your laptop is able to start. Be on the lookout for any beeps. A sequence of beeps may be heard if a laptop motherboard component fails. You may tell which component has failed by counting the number of beeps. You can learn more about your laptop’s make and model by looking up the number of beeps on the manufacturer’s website.
Attempt a hard reboot. If your laptop unexpectedly shut down while you were using it, this could be because an electric shock prompted the motherboard’s safety mechanism to disconnect power. This is done to prevent overheating of delicate components.
The battery, power adapter, and the power button can all be held down for 30 seconds to clear any remaining electricity. Reconnect the power cord, wait thirty seconds, and then power up the computer. If your laptop powers on, remove the battery and replace it. Reinstalling the battery may not get the laptop up and running, so you’ll need to buy a new one.
Cooling vents should be clear. Laptops feature built-in safety mechanisms that shut down your computer if any of its components overheat. Overheating can occur for a variety of reasons, but the most common is that the laptop’s cooling vents are blocked when it is resting on a pillow or sofa. Avoid this if you want to keep the temperature of your laptop under control.
To avoid overheating, it’s also a good idea to thoroughly clean all of the vents in your laptop casing. In this case, the CMOS battery needs to be swapped out. The CMOS on a laptop motherboard is powered by a small circular battery, which enables the BIOS to load the os and all input and output devices during bootup. The laptop won’t boot up if the battery isn’t fully charged. If you feel confident opening the case, you can change the CMOS battery yourself. As a result, the majority of people choose to have it changed by an expert.
Any parts that have been installed recently should be removed and replaced. Please tell me if you recently installed any new RAM or HDDs. If your laptop didn’t start after that, it could be an indication that the new hardware isn’t working properly. The old component can be returned and a working replacement can be obtained by sending the new one back to the place of purchase for testing.
Go to a repair shop for the laptop. It’s possible that a failed part on the laptop motherboard is to blame if none of the aforementioned troubleshooting methods worked. If your laptop is still covered by a manufacturer’s warranty, sending it in for service is your best bet; otherwise, you can get it repaired by a third party.
Laptops, like all electronic devices, have a limited lifespan. If your laptop is out of warranty and repair costs are high, it may be more cost-effective to buy a new one. If you do decide to replace it, consider repurposing the old one rather than throwing it away.
