The low-power charger Chromebook notification might take you by surprise. You can see it due to many reasons on various models of Chromebooks.

If you’d like to resolve the error or want to confirm if your battery is faulty and needs repair, read this guide until the end. My DIY troubleshooting methods will help you fix the problem at home.

What Does”Low-Power Charger” Mean on Chromebook?

Low-power charger is a ChromeOS notification found near the clock on the Shelf. When you connect a Chromebook battery charging source with a lesser rating than the rated power adapter, you’ll see this message.

For example, the Google Pixelbook Go comes with a 47 Wh battery. Now, if you connect any charger less than the rated charging power (47 Wh), you’ll get this notification.

It also tells you that the battery is charging but the speed isn’t reliable or it’s very slow.

I already mentioned the primary reason behind this notification. Here are the other possible reasons:

  1. The original charging adapter is faulty.
  2. The third-party charger you’re using is of substandard quality. It might be rated 50 Wh but it’s delivering merely 20 Wh.
  3. Your ChromeOS has a bug and needs updating.
  4. The Embedded Controller (EC) of the Chromebook PCB isn’t functioning properly.

What To Do When You See the Low-Power Charger Message on Chromebook?

Here’s how to handle the low-power charger notification on your Chromebook of any model:

Solution 01: Inspect the Power Adapter

Regular wear and tear affects the power adapter cable. It might not be carrying enough power needed to charge your Chromebook in its rated Watt-hour (Wh) value. You can remove the power cable from all of its connection points. Then reconnect and try to charge the Chromebook again.

Sometimes, there could be dirt, dust, and carbon build-up. Wipe clean these connecting ports with a dry cotton swab. After the cleaning, try charging the device.

Solution 02: Plug In the Original Power Adapter

If you’re using a third-party power adapter and you see this notification, it clearly means that the charger isn’t suitable for optimum or fast charging.

Switch to the original charger that came with the device. If you don’t see the notification anymore, your Chromebook and battery are in good condition.

Sometimes, you may intentionally use a low-rated battery charger for your Chromebook. Even I do this to extend the lifetime of the battery.

A rechargeable Li-ion battery comes with a limited charging cycle. Most laptop batteries of the Li-ion class including your Chromebook come with 500 to 1,000 cycles. After 500 or 1K cycles, battery capacity decreases.

Solution 03: Use an Alternative Power Adapter

If the issue persists, you may need to use a completely different charger. If you’ve got a USB Type-C power adapter with a 45 Wh or more power rating, you can use that. Here’s how you can use a USB-C adapter:

  1. Click the clock and then click on the gear icon to open Chromebook Settings.
  2. Click on the Device option on the left-side navigation panel.
  3. Under the Device section, you should see Power. Click on that.
  4. On the next screen, click on the Power source drop-down list.USB c source
  5. The list will expand and there you can choose any of the USB-C ports.
  6. Now, connect the USB-C charger.

If you don’t have an alternative USB-C charger or a pin-type laptop charger, you can get one from brands like Belkin, Anker, etc., on eBay or Amazon. Go for 45 Wh USB-C type chargers.

Solution 04: Perform a Battery Health Check

Find out if the battery is in good condition using the following methods:

Using the Terminal App

  1. When on the Chromebook desktop, press Ctrl + Alt + T.
  2. This will launch the ChromeOS Terminal.
  3. On the Terminal app, type the following command and hit Enter:
    battery_test 10battery test 10
  4. After a while, the Terminal window will show Battery health: (with a percent).
  5. If the percent value is below 50%, it’s not in good shape.
  6. If the percent value is above 50%, move on to the next troubleshooting method.

Using ChromeOS Diagnostics Tool

  1. Click on the ChromeOS Settings icon.
  2. On the Settings screen, click About Chrome OS.
  3. If it’s ChromeOS 90 or newer, you should see the Diagnostics option on the right-side menu.
  4. Click the Diagnostics link.
  5. Under the Battery section, you should find the Battery health indicator with a percentage value, like 50%, 70%, etc.

  6. If it’s above 50%, the battery is okay.
  7. If it’s below 50%, go to an authorized service center for repair or replacement of your Chromebook battery.

If you find the battery is faulty, contact the manufacturer for hardware support or warranty claims.

Solution 05: Power Cycle the Chromebook
