Dunno. I bought a 12 volt universal PS for my laptops which works with both of them in the car. Cost under 20 quid.

I've used one with an IBM laptop. The fact that it was IBM, not Lenovo, does however tell you it wasn't last week.

It depends on the PSU. Cheap ones (yes I'm looking at you Targus) can fail when used with "modified sine wave". Some others (Apple I'm looking at you) make alarming buzzing noises. Some (Dell, IBM, Samsung) don't seem to have a problem.

Given that sine wave inverters have dropped in price I would use one of those.
