I went through this same process a couple of years ago. Initially it made no sense that a computer that uses components running on 12, 5, 3.3 and maybe 2.5vdc couldn't run off of a 12 vdc car battery. Ultimately it turned out that it was the vendors choice of laptop battery that was the problem.

The Ah of a battery may depend quite a lot on the current drawn from it; I'd look for a datasheet, it probably has an Ah/current graph. You need a pretty high-power switcher to feed that current at 19.5VDC, in electronics-land that's a TON of power. Definitely something with an external power FET
