Note that running a laptop with no battery is not necessarily a good idea - some laptops rely on the battery to act as a voltage regulator. Running a laptop without its aku pack is how I fried a RAM bank in my Toshiba T1100 a couple of years ago. I realized too late that the power supply was delivering a much higher voltage than what the laptop expected, and needed to be brought down by the battery not to damage anything. More recent constructions are probably sturdier, but one should be careful nonetheless.

Not necessarily. As a laptop with a full charge battery should not be power through the battery when connected to the mains. And for what it is worth, I have one Dell laptop that I am running for more than 10 years now without an inserted battery, as the charging circuit is not operational. But it works just fine, with a great 1600x1280 screen, when just ran off the AC adapter.

But then this is a pure hardware issue, and nothing related to FreeDOS...
