The reset button is good advice which we should take note when troubleshooting any piece of electronics. Unfortunately not every electronic device has one which includes the Geekvape Aegis Legend.
@dylantyqq – Sorry to hear about your troubles. A device not booting up or even recognized by your computer leads me to believe there maybe a hardware fault in which case you will have to follow the RMA procedures. I do not know what they are.
There is a multitude of components needed to build what is referred to as the “chipset”, all of which are picked out of a bin. A small component such as an inductor or capacitor may pass their initial QC but could fail during prolonged use or under stress. It happens with even the best and most sophisticated of electronics. A tighter, more strict quality control ads cost to production which in turn ads cost to an end product. In order to stay competitive, manufactures have to sacrifice a certain level of QC so that their product is not priced beyond the reach or interest of your average consumer.
A Geekvape representative does frequent these forums. Perhaps post your issue in the Geekvape Aegis Legend thread where they have been known to respond. Link below.
