After i replace my battery with a new one, my calculator still didn’t work, except if i remove the battery and use the solar panel, before it comes on. Please help
Possible issues are the battery you got is dead which is possible, the battery connector isn’t making good connection (Normally will look as if the clip is lifting, try putting the battery in and holding it with your finger), you used the wrong battery or there’s a trace somewhere that’s broken. Try looking for these things. Hope this helps!
Try checking whether the battery is placed correctly or check the wires connecting the batteries to the m- board
Same problem for me. Above methods doesn’t work. Did it work if I replace the wires to solar panel in to the battery? Or have to do anything more?
