I had Business Billing at work tonight. Always a joy... All my thought is bent on my weekend, which begins in about 24 hours. I've been casually looking around on the internet for ways to power a laptop with an automotive cigarette lighter. The rough industry standard for the amount of time a laptop can stay powered, without being plugged in, is about 2 to 2 1/2 hours. However, I have been told that this is with things that use a lot of power drawing it, such as the speakers, the CD/DVD drive(s), and the screen. My plan will be to be running Winamp on the laptop, with a playlist of all of my songs on it, with a headphone jack-to-cassette adapter for the car. If the screen is runnning, lots of power will be used, but I have it set that my laptop, when closed, has no effect on any running programs. I will get a USB gamepad, and control the tunes with that, making for a safer drive. planning trips, for me, is almost as fun as actually taking them.
