I have a technical question. This may not be where to post it, but I'm shooting in the dark, anyway!

I have an old Dell 7500 laptop that works fine. I also have two batteries for it and the plug-in AC charger for the unit.

Here's my question:

Has anyone seen any way to use a 12-volt car battery to power the unit, instead of the built-in batteries, which are apparently 10.8 volts? I'm an amateur radio operator, so I have knowledge of electrical circuits, but I also don't want to mess up my laptop or the charger. Obviously, a couple of silicon diodes in series with the 12 volts could drop the voltage down to about that level, depending on the load, but I just wondered if anyone here had done anything like this.

Anyone out there have ideas or an answer?
