I've had to replace both battery and keyboard twice: I'm on my third of each. The battery was always crap, never delivered quoted run time. I think the keyboard was similarly a weak point in an otherwise pretty solid unit. Buy yourself a replacement keyboard (& battery too, while you're at it) on eBay: Lenovo is no longer carrying either part. Probably dumped their remaining service spares on eBay. You're bound to need them. The screen unit (contains all the electronics) is pretty robust and is serviceable. The keyboard is neither: if it's shot you cannot fix it. Worst case, use an external portable Bluetooth keyboard + mouse.
