Get your keyboard at a comfortable angle. Laptops used to come with little pop-out legs in the back to set the keyboard at an angle (I'm really dating myself). These days, to position the keyboard at an angle, you can prop the back of the laptop on a small book or other widget.
Make the screen brighter. Dim screens are better for battery life, but you'll get a headache staring at a low contrast screen for hours on end. Bring a power cable so you can plug in and crank the brightness until it's comfortable to see.
Use a separate mouse. Integrated touchpads or pointing sticks are clumsy to use for extended periods. Invest in a small portable Bluetooth mouse. Likewise, many ergo experts advise using a separate keyboard so you can position the laptop for optimum display position. This isn't practical on the road, but you might consider it if you use the laptop as your primary PC in the office.
Position the laptop for the task at hand. If you're doing a lot of typing, your wrists should be straight and elbows at a 90 degree angle, as if you were typing on a keyboard in the office. For many people, that might mean putting the laptop in your lap. But if you're mainly reading, that's a bad place for the screen -- elevate it to near eye level (you can put it on a stack of magazines or books).
Carry it in comfort. Your laptop, mouse, power supply, and other accessories probably weigh anywhere from 5 to 10 pounds. Be sure to carry it all in a bag that has a wide, padded strap to distribute all that weight comfortably across your shoulder. Even better -- consider a rolling case so you don't have to carry it at all.
