battery change
I have a lenovo Legion y740 and recently my battery stopped charging. It stays on if its plugged in, but will no longer hold a charge. I didn't know if it was the charger or the battery so I bought a new one of each and the new battery won't charge either, with the new or old charger. But I noticed after I changed the battery, my PCI Device and SM Bus controller are no longer working in my device manager. Is that what is causing the battery not to charge? I ordered another, better battery, which is coming in a day or two, so I'll see if that makes any difference. I tried reinstalling the drivers but it doesn't work. Any advice or words of wisdom? It is no longer under warranty, or even supported anymore, so I'm not sure what to do.
