Reply To: chuwi hi13 not working

We can only speculate at this stage, but it’s possible that the unit is only “charged” at the factory during the windows image upload, which I imagine should only take them a couple minutes to do…..and if this is the only “charge” the unit get before shipping(which is very little in that case), it does not seem impossible that it has enough time to decline close to the critical 0% capacity.  Batteries are also faster to discharge, when stored in a cold enviroment. I remember touching my Hi13 unit it felt cold like ice, so I left it to dehydrate/warm-up for 6-7 hours before even attempting to turning it on.

You are right in your assumption, that leaving a battery discharged can make it impossible or at least risky to attempt to charge it again.  As I mentioned before, the battery will suddenly act as an electrical shorted wire and for a short time(miliseconds)create a very high peak powerdraw, which could posibly lead  into damaging the powersupply unit, as the peak power will go higher than what the powersupply can deliver/is rated.  And again, this action can lead to anything from a defect powersupply or/and damage to the electrical battery/power- curcuit inside the unit.

There is also the “easy fix” possibility, if the battery works and then suddenly drops to 0%…..this could be caused by something as simple as the battery connector being loose and be repaired by tightening/re-connecting the plug. But of course, there is the issue of openening the unit will void the warranty….
