Reach RS+ won't Power On

Hi,
We’ve got two Reach RS+ units. One used as a base, one as a rover.
Yesterday I plugged it into a microUSB to charge, but no blinking orange light. I tried to turn it on, but nothing, no lights at all. I tried the cable on the other RS+ unit and it immediately started blinking orange to indicate it is charging, so I don’t think there is an issue with the charger or cable. I have also tested another cable and charger, and got the same response.

I left the ‘base’ plugged in overnight hoping the extended period might somehow bring it back to life. Today the orange light has started blinking, but i still cannot get the unit to turn on.
If i hold down the power button the other lights (NET and STAT) light up, but go off as soon as i release the power button.

Hi Alex,

Since further troubleshooting requires sensitive information, could you send the Serial number and photos of the unit to support@emlid.com?
