 ==== Battery ====
 The battery obviously determines how long the computer will work without being plugged in. There are two sides to this: the total capacity of the battery and how energy efficient the laptop is, particularly the processor. The manufacturers often give a figure of how long they think the battery lasts, which is to be taken with a pinch of salt. Reviews will tell you how well it stands up to real world tests.

+===== Screens =====
 There are many different aspects to the screen. There's the size, the resolution and various aspects of quality of the picture.

 ==== Colour coverage, brightness etc ====
+For those that work with print publishing, the colour coverage is very important. Otherwise, it becomes very difficult to get the screen to match with the printed matter. This is particularly important for professional print colour jobs.
-For those that work with print publishing, the colour coverage is very important. Otherwise, it becomes very difficult to get the screen to match
+For colour coverage there are two standard measurements. One is sRGB which is less demanding, and where really any screen used for print layout should manage to get to the high 80s or 90s. The other is Adobe RGB where the best screens are in their 80s and 90s. Even for black and white printing it could be necessary. Here black level, gamma and contrast ratio will be the important measurements.
+If planning to use a laptop screen outside or inside with direct sunlight, you want the screen to manage a high level of brightness and contrast ratio. Also, you'd want a matt, rather than glossy finish, as the latter reflects background light.
+All these makes for a lot of variables, but a good review should cover all these aspects, and explain where the screen, whether stand-alone or part of a laptop, falls short.
