Does it have two batteries I have changed small battery of 1.5 V but not working. Then if I will change this bigger battery then will it work

It worked for Me, my calculator is Fx-991 ES Plus 2nd Edition. When I first bought it I tested it at the store, works well. But 2 days later when I brought it to school during my engineering classes, it just wont turn on, but it turns on when there's sunlight on it's panel, and so it's "solar powered" now, I struggled with it up until I saw this video. Thank you very much! I opened my calculator and I tried removing my battery, and placed it back again (I failed at removing it because it got locks, and I was hesitant to remove it and lazy haha) and when I pushed it down I tried to click the on button, and it worked! I closed it again and sealed it and voila. Thank you thank you thank you!

When I keep my calculator warm it's working so whenever i do calculation i placed it under my buttock for a while and after that its start working . 😂😂
