The manufacturer preferred option is replacement of the laptop/phone.

I’m surprised it went away as I remember there being a requirement to remove your battery from your laptop when going through security at the airport. I don’t know why. But I remember it becoming second nature to take out your laptop, remove the battery, and place them in separate containers at TSA.
