In addition to the EliteBook series, the ProBook series was also upgraded, in many respects similar to the first. It includes 7 laptops with a diagonal of 14 to 17 inches: 4440s, 4540s, 4545s, 4740s, 6470b, 6475b and 6570b. Detailed specifications are described in the two tables below, compiled by our colleagues from Laptop Mag . We'll tell you about some features. So, the chassis and body of the models whose names end with b are made of aluminum and magnesium alloy of dark color, resistant to scratches and other elements of spoilage, and for models ending in s, from gray aluminum covered with a special composition against scratches. Funny, but all models, despite the difference in size, have a completely identical set of connectors (separate lines s and b). As for prices, in the US HP ProBook 6470b and 6570b start at $ 770, HP ProBook 6475b - c $ 670, and line s - with $ 590. The start of sales is scheduled for June 4 (something recently, many manufacturers are obsessed with this date, do not you think so?).
