The HTC Vive VR headset has its own set of controllers when you buy it. But there are times where they may simply give up the ghost.
There are ways to fix these issues, and we don't recommend doing it yourself; have it checked with a professional.
And the good thing here is, there may be an opportunity to send them back to HTC themselves.
With that, here's how to fix the HTC Vive controllers.
Fix your HTC Vive controllers by checking its available charge capacity
According to VR owners, one way to fix your controllers if it doesn't work properly is to check its available charge capacity.
One indicator about a not-so-good state of your controller's battery is when the signal light set on it turns into a blinking red variant.
In case this happens, immediately plug in the controller that is currently having a low battery charge.
If the indicator light turns orange, it's now charging and stacking power again.
