Hello ! Both in my linux and windows operating system the battery information shown is wrong : In linux the battery is always seen at 0 percent. In windows the battery is always seen at 100 percent. Sometimes linux and windows will agree in a percentage but it won't ever go up or down. The battery percentage sometimes changes if I plug/unplug the laptop multiple times, but afterwards it will stay stuck at the "new" value. My Product number is : RZ09-02386G91 and I would gladly like to know how to fix this issue.
