I have a Lenovo Yoga 710-14IKB. It went dead and now doesn’t charge or power on. I think the battery might be drained. I...

I never did. I didn’t want to buy a new battery unless I knew it was 100% going to fix it. I ended up dropping it off to best buy to recycle it

Thanks Mike. The problem I have is the laptop is 100% off and will not power on at all. When the laptop is plugged in the charging light does not come on either. I have disconnected the battery and plugged it into the main power and still nothing.

I don’t believe these laptops have a cmos battery
