When it is plugged in, a blinking HP charger could be an indicator that either the battery is defective or your laptop battery is not properly connected.

Therefore, if the battery is defective, you may want to replace it with one compatible with your HP laptop model. If this is not the case, consider confirming and ensuring that the laptop battery is properly connected.

A common reason your Asus charger blinks when plugged in is that the laptop battery is getting older.

It can also be due to a damaged laptop charger. You need to check the battery icon on the taskbar of your laptop and confirm if the battery icon has an electric plug above it.

An absence of an electric icon will confirm to you that your laptop charger is damaged.

Therefore, you can fix that by replacing your laptop charger with a charger compatible with your Asus laptop.

The blinking can also be a short circuit or temporary failure of the AC adapter. In this case, you should unplug the AC adapter from the power outlet and laptop and plug back all the cords correctly.

Besides, the orange blinking in your laptop charger when plugged in could mean that your laptop battery sensors need recalibration.

There are three types of Dell charger blinking that you might experience when your laptop charger is plugged in.

1. Amber light and white light alternately blinking.

This indicates that a non-Dell or unsupported AC adapter is connected to your Dell laptop.

You can fix this by first disconnecting and reconnecting your AC adapter. If this does not work, you can try a known Dell AC adapter.

2. A constantly or steady blinking amber light

This will be a signal that there is a possible fatal laptop battery failure.

Here is how you can fix it;

Step 1: Turn off your laptop

Step 2: Disconnect the AC adapter

Step 3: Reseat the laptop battery

Step 4: Replace the laptop battery with another compatible or similar Dell laptop battery

3. Steadly blinking white light and an alternately blinking amber light

A temporary Dell laptop battery failure causes this.

The following steps will help you fix the issue;

Step 1: Turn off your Dell laptop

Step 2: Disconnect the AC adapter

Step 3: Reseat the battery and replace it with a similar Dell laptop battery.

Typically, there are two scenarios when your Lenovo charger will blink when plugged in. First, a slow blinking will indicate that your Lenovo laptop battery is being charged.

Secondly, a quick blinking will be an indicator that there is a possible battery or AC adapter problem. It might be associated with a faulty charger that is not sending power to your laptop battery.

To fix this issue, you will need to do the following;

  • Shut down your Lenovo laptop
  • Remove the AC adapter and battery
  • Press and hold the laptop’s power button for 20 to 30 seconds.
  • Replace the AC adapter and battery
  • Boot up your Lenovo laptop

It is vital to note that the above fix will not resolve the issue if it is associated with a faulty charger. Therefore, if the above fix does not resolve the problem, consider replacing your Lenovo laptop charger.

In most cases, whenever an Acer laptop charger blinks with an orange color when plugged in, it will indicate a possible faulty laptop charger. It may also be due to a lower power supply from the AC socket outlet.

You can easily fix this problem by replacing your Acer laptop charger or adapter. If the issue is associated with a lower power supply from the AC source, you will be required to check and ensure that the electric voltage supplied to the AC socket-outlet is enough to charge your Acer laptop.

A blinking white light in your Microsoft Surface charger when it is plugged in can indicate a problem with the power supply, or the power supply connector could be incompatible with your laptop.

You can fix this by removing the power supply connector from your laptop and checking for debris or damage that can cause a bad connection. If this does not resolve the issue, you may want to replace the power supply.

A blinking red light on your MSI charger can be a signal that your laptop battery is not being charged properly. This could be due to a dead battery, faulty wall socket, or a faulty charger.

Depending on the specific cause, you can fix this by;

  • Changing the wall socket
  • Replacing the MSI battery charger with one that is compatible with your laptop
  • Replacing the MSI laptop battery with a compatible battery

In most cases, your Razer laptop will stop charging, and you will notice a charging light that is slowly blinking green (low light). This issue is associated with a faulty Razer laptop charger in most cases.

You can fix this by buying a new charger compatible with your Razer laptop.

If a Samsung charger blinks when it’s plugged in, it may indicate a problem with the laptop battery. The power usage of your Samsung laptop is greater than the recharge capability of the Samsung battery.

In such a case, if the battery is damaged, you should consider replacing it to fix the issue.

Laptop Charger Light Error Codes

The laptop charger was equipped with this little light as a way for the charger to communicate or display its status. It sends error codes by displaying lights in different colors and patterns. The meaning of these lights can differ from one model to the next.

Some error codes are, however, quite frequently used by manufacturers all over the world. These include:

  • Blinking Amber: The laptop’s battery is low
  • Blinking Amber and White: The laptop isn’t compatible with the charger used
  • Blinking White: The laptop is in sleep mode
  • Steady White Light 1: The laptop is turned on
  • Steady White Light 2: The laptop’s battery is being charged
  • No Light: This can be seen when the charger isn’t connected to a power supply or working battery, but also when the laptop is fully charged
