Put them on the charger correctly  \n- The **left arm** of the Ally Solos contains the **magnetic charging port and an LED indicator**. For charging to work and for any visual indication, the charger must be properly connected to that left arm.([support.letsenvision.com](https://support.letsenvision.com/hc/en-us/articles/38093860157969-How-do-I-charge-my-Ally-Solos-Glasses?utm_source=openai))  \n- Be sure you're using a **wall adapter** (not just a laptop or PC USB port). The official support articles state that wall power ensures enough voltage and current; charging from a computer or laptop may not deliver a visible light due to lower power delivery.([support.letsenvision.com](https://support.letsenvision.com/hc/en-us/articles/38093860157969-How-do-I-charge-my-Ally-Solos-Glasses?utm_source=openai))\n\n---\n\n### 2. LED colors and what they mean  \n- When charging via the magnetic cable, the **LED turns red** to indicate \u201ccharging in progress.\u201d([support.letsenvision.com](https://support.letsenvision.com/hc/en-us/articles/38093860157969-How-do-I-charge-my-Ally-Solos-Glasses?utm_source=openai))  \n- When fully charged, the LED should turn **blue**.([support.letsenvision.com](https://support.letsenvision.com/hc/en-us/articles/38093860157969-How-do-I-charge-my-Ally-Solos-Glasses?utm_source=openai))  \n\n---\n\n### 3. Verbal cues via audio feedback  \n- If you can\u2019t see the light (due to its location or ambient light), there are **audio messages** that the glasses speak when plugged in or unplugged, announcing battery level status.([visionmatters.net](https://visionmatters.net/wp-content/uploads/2022/09/Envision-Glasses-User-Guide.pdf?utm_source=openai))  \n\n---\n\n### 4. Use the Envision / Ally app  \n- Your phone app should show battery details once the glasses are properly charging. You can usually find this info in the \u201cGlasses\u201d or device status section of the app.([letsenvision.com](https://www.letsenvision.com/start?utm_source=openai))  \n\n---\n\n### 5. Common reasons why the indicator isn\u2019t lighting up  \nHere are possible reasons if you see **no light**:\n\n| Issue | What to check/do |\n|---|------------------|\n| The charger or port isn\u2019t making good contact | Ensure the magnetic cable is fully snapped into the charging port on the bottom edge of the **left arm**.([support.letsenvision.com](https://support.letsenvision.com/hc/en-us/articles/38093860157969-How-do-I-charge-my-Ally-Solos-Glasses?utm_source=openai)) |\n| Adapter not supplying enough power | Use a wall adapter that supplies adequate current (not just a laptop USB port).([support.letsenvision.com](https://support.letsenvision.com/hc/en-us/articles/38093860157969-How-do-I-charge-my-Ally-Solos-Glasses?utm_source=openai)) |\n| Battery fully depleted | If the left arm drops to 0%, it may need to be charged via USB-C (not only via magnetic cable) to restore enough power for LEDs and functions.([support.letsenvision.com](https://support.letsenvision.com/hc/en-us/articles/38093860157969-How-do-I-charge-my-Ally-Solos-Glasses?utm_source=openai)) |\n| Firmware or hardware issue | If none of this works, there may be a software or hardware fault. Contact support or check for firmware updates through the app. |\n\n---\n\nIf you tell me whether \u201cthere is no light at all\u201d or \u201cyou can\u2019t see the light,\u201d I can help you pin down which of these might be the cause for your situation."

It might not light immediately if the battery is severely depleted. ([support.letsenvision.com](https://support.letsenvision.com/hc/en-us/articles/38093860157969-How-do-I-charge-my-Ally-Solos-Glasses?utm_source=openai)) |\n| USB-C connector issue with left arm | Make sure the USB-C cable is fully and properly inserted in the **left arm\u2019s port**, which is near the hinge. A loose or misaligned connection could prevent the light from turning on. ([support.letsenvision.com](https://support.letsenvision.com/hc/en-us/article_attachments/40477988619153?utm_source=openai)) |\n| Power source insufficient | The support article mentions that USB ports on computers or low-quality adapters might not supply enough power to trigger the LED on the left arm until it has regained some charge. A wall adapter delivering adequate current is preferred. ([support.letsenvision.com](https://support.letsenvision.com/hc/en-us/articles/38093860157969-How-do-I-charge-my-Ally-Solos-Glasses?utm_source=openai)) |\n| Firmware/hardware issues or loose connection after detaching/re-attaching | If the left arm has been removed earlier (for USB-C charging or other reasons), ensure it\u2019s reattached securely\u2014flush and without any gaps\u2014because poor connections can prevent the arm from charging or lighting up properly. ([support.letsenvision.com](https://support.letsenvision.com/hc/en-us/articles/38093860157969-How-do-I-charge-my-Ally-Solos-Glasses?utm_source=openai)) |\n\n---\n\n### \ud83d\udd0b What you can try\n\nHere are steps to help ensure the left arm is charging (and signaling properly):\n\n1. **Use a wall adapter** rather than a USB port on a computer, especially if the left arm is very low on battery.  \n2. **Leave the left arm plugged in via USB-C** for at least one hour. If it was at 0%, this gives it time to climb out of the deep discharge and allow LED behavior.  \n3. **Check the cable and port** for damage or debris, and make sure the arm is fully and firmly plugged in.  \n4. **Visually inspect or ask someone** to watch the LED on the left arm, since angle, lighting, or obstructions could make the light hard to see.  \n5. **Power button test**: after charging for a while, press and hold the power button for several seconds (about 6 seconds) to hear \u201cPower High\u201d\u2014this may indicate battery health and charging status. ([support.letsenvision.com](https://support.letsenvision.com/hc/en-us/article_attachments/40477988619153?utm_source=openai))  \n\n---\n\nIf after trying all this the left arm still shows **no red light or visual cue**, then it might indicate a hardware issue\u2014something like a defective LED or charging circuit. In that case, contacting **Envision support** for repair or replacement under warranty would be recommended.\n\nIf you like, I can walk you through checking your firmware version and doing some manual diagnostics to help Envision support diagnose things faster. Do you want to try that?"
