# I am having trouble powering on my M-Series smart glasses. What can I do?

This is likely an issue with the level of charge on the batteries in your M-Series Smart Glasses. The M-Series Smart Glasses contain two batteries, the primary battery within the M-Series Battery Pod, as well as a small fail-over battery in the M-Series Smart Glasses main unit to support the hot-swapping functionality of the Battery Pod.

If the internal fail-over battery does not have sufficient charge, the M-Series Smart Glasses will not boot. It is important that prior to first use, the M-Series Smart Glasses are charged, fully assembled, and connected to a power source supplying a minimum of 1.5A.

When not using your M-Series Smart Glasses, it is important to disconnect the battery from the main unit and ensure that the unit is powered down by holding the power button for a few seconds and then selecting power off from the pop-up menu and then confirm by selecting “OK”. The internal battery should not drain, and you can simply charge the battery pod alone from a power source supplying a minimum of 0.5A.

If you are still having trouble, please contact [Vuzix Technical Support](mailto:technical_support@vuzix.com).
