12v Laptop Recommendation?

Can any one recommend a laptop that can be run/charged from a 12 volt power supply like those found in cars (cigarette lighter sockets). I know that some laptops have a power rating far to high for a 12 volt power supply.

IBM Thinkpad (or Lenovo as it's called now) - They will work from a cigarette lighter socket.
Get a power inverter and you can run any laptop from your car.
You should just get a power converter from Radio Shack or where ever ,I have one that I use for my cell phone ,lap top etc.They're pretty cheap and plug into your lighter then have a normal house electrical plug on the other side. I have only used it with my laptop when the vehicle was running (it worked good)so I don't know if it would kill the car battery quickly -ask before you buy.
Have a look at the website below for power inverters.
Get an inverter off ebay, So much cheaper than shops!
