110V power inverters with R60

[allan]

Hi all - I've done a lot of searching on this but still am not sure. The best I can find is that "some" laptops shouldn't be used with a modified sine wave 12V to 110V AC inverter. Only a true sine wave output can be used.
I was wondering if anyone had looked into this and found out anything specific to this laptop.

Thanks in advance,
