Hi guys, does anyone know how to fix this problem that happens every now and then on lenovo yoga slim 6i. Last time I got charged $150 asking someone to fix it , they said something about it being a software problem then they fixed it. Then this problem happened again last month and the laptop magically fixed it on its own after a week and now it happened again. I swear this is so annoying because I can't use my touch pad. So I'd really appreciate if anyone would kindly give me some advice on how to deal will this because I'm a student and it seriously affects my life in a lot of ways. Thank you very much!
