Why is the Razer Nabu X not charging?

Many factors can contribute to the Nabu X's battery not charging, including:

  • Dirty charging contacts.
  • Faulty charging sources (e.g. USB port or plug).
  • A defective USB charging cable

Please go through the following steps:

  1. Clean the charging contacts by using warm water and a cotton swab. Carefully clean the charging contacts on your Nabu X and charger. If a cotton swab does not fully remove the dirt or debris, use a toothpick or toothbrush. Do not submerge your Nabu X in hot water or use abrasive cleaners. Thoroughly dry your Nabu X before attempting to charge.
  2. Try a different USB port. Your charger may not be getting enough power from the USB port it is plugged into or the USB port may be defective. Avoid using USB hubs.
  3. Try restarting your Nabu X.

Power or unpowered USB hubs do not always provide a consistent output to charge your Nabu X. If you are using a USB hub, try connecting the USB charging cable directly to your computer's USB port or a USB wall charger. If your Nabu X starts charging while directly plugged in, the USB hub is not providing enough power and should not be used.

If you have done these steps and you are still having trouble charging the Nabu X, contact Razer Support for further assistance.
