laptop charging light

Laptop charger lights are not all the same. Some are solid. Others will blink. Some are green. Others are red. You even have a few that are yellow. Which light is good? Which one is bad? This guide will attempt to provide some answers.

Laptop Charger Green Light Meaning

A lot of laptop chargers use a green light to show that they are working.

But the meaning behind that green light will vary depending on what the light is doing, that is to say, whether it is blinking, flashing, staying on, going off, etc.

You should always consult the manual if you have any questions about the meaning behind a green laptop charger light.

Laptop Charger Green Light Won’t Turn On – Why?

If the green light is off, start by finding out whether or not the charger has been plugged into an outlet. The green light will only go on if the charger is connected to a power source. If the plug is inside an outlet, make sure it is firm. A plug whose prongs are exposed can damage the charger.

It may also refuse to transmit the power the charger needs to operate your laptop. If the plug has been securely connected to an outlet but the green light is still off, turn your attention to the laptop.

Is it charging?

If the answer is yes, a defective component in the charger has compromised the green LED. This shouldn’t concern you if the laptop is still charging.

On the other hand, if the laptop shows no signs of charging, you should assume that the laptop charger is dead. Get a new one.

Green Light Is Blinking In Laptop Charger – Why?

A functional laptop charger should display a solid green light. If the laptop charger light keeps blinking, the charger is defective.

Either the adapter is failing or the power jack has a problem. Power jacks tend to develop problems because people keep flexing them. Fortunately, they are cheap, so finding a replacement shouldn’t take long unless your laptop model is rare.

Laptop Charger Flashing Green Light – Why?

Flashing laptop charger lights are caused by a short on the motherboard. The light will only flash when you plug the charger into the laptop. The adapter may respond to the short on the motherboard by shutting itself off and refusing to charge the battery.

Green Light Goes Off In Laptop Charger – Why?

If the green laptop charger light goes off when you connect the charger to the laptop, the battery is probably at fault. If the battery is so old and defective that it cannot hold a charge, the charger will stop working whenever you connect it to the laptop because it cannot transmit power to the battery.

You can test this theory by taking the battery out. If the charger starts working, you should replace the battery.

But if the light is still going off and the charger has refused to work, you have a bigger problem on your hands. More than likely, you have a short on the motherboard.

Depending on the seriousness of the problem, your technician may encourage you to replace the entire motherboard.

Laptop Charger Yellow Light Meaning

In many cases, a yellow light shows that the battery is almost out of charge. The computer is telling you to charge the battery before it’s too late.

But It really depends on your machine. Different models will use different lights to refer to different things.

But you cannot be certain until you read the manual. It will give you a definitive answer. In some models, a yellow light could mean that the charger and battery are working optimally.

Laptop Charger Orange Light Meaning

An orange light shows that the HP notebook is charging. The color will change to white once the laptop is fully charged. In brands like Asus and Toshiba, the orange light is similar to the yellow light, that is to say, it shows that the battery is low and you should charge it.

Laptop Charger Blinking Orange – Why?

A blinking orange or amber light indicates that the battery is low. The orange light will start blinking once the battery power falls below 10 percent.

If the battery has plenty of power but the orange light is blinking, you may have a damaged and defective laptop charger or battery.

Once again, the easiest way to decipher the meaning behind the blinking light is to consult the manual.

Laptop Charger Red Light Meaning

A red light alerts the user that the battery is depleted and requires charging. Red light can also indicate that the laptop is charging.

Laptop Charging Light Blinking Red – Why?

A solid red light suggests that the battery is either dead or very low on charge. A blinking red light has a similar meaning. It shows that the battery has very little charge, so much so that it cannot start the computer.

According to Gemwon, the red light will start blinking once the charge falls below a certain threshold. It will keep blinking until you connect the computer to a power source.

Laptop Charger Blue Light Meaning

A blue laptop charger light is similar to a green light. It shows that the battery is fully charged. A blinking blue light indicates that the battery is charging normally.

Laptop Charger Blue Light Turns Off – Why?

If the blue light goes off whenever you connect the charger to the laptop, you may have a damaged or defective power jack. If the power jack is fine, the best-case scenario is a dead adapter.

Replacing an adapter sounds annoying. But it is better than replacing the motherboard, which is what the technician may suggest if a short on the motherboard is causing the charger to turn off whenever you connect it to the laptop.

Laptop Charging Light Solid White – Meaning

A solid white light means that a laptop is fully charged. The power is somewhere between 95 and 100 percent.

Laptop Charger White Light Blinking When Plugged In – Why?

A blinking white light can indicate a defective battery. The white light will also blink in situations where the battery is not properly connected. Blinking lights are normally a sign of trouble. Check the manual for confirmation.

Unless you know what you’re doing, you should hire a technician to troubleshoot the computer. They may solve the problem by simply updating the BIOS.

1). Solid White – This means that the computer is on

2). Flashing White – The computer is in standby mode.

3). White Light Off – This can indicate hibernation, the absence of AC power, or a battery

4). Flashing Amber and then White – This happens when people use an AC adapter the laptop doesn’t support
