The A Series was launched in 2010 and initially consisted of the "all-round" models A530, AH530 and AH550, which are offered in different variants.
Similarities were displays with 39.6 cm (15.6 inches) diagonal, false led backlighting and 1366 × 768 pixels (16:9 aspect ratio, with or without anti-glare protection), as well as the built-in Intel HM55 chipset and keyboards with a numeric keypad.
The devices are mainly equipped with mobile processors from the Intel Core i series offered.
The special thing about the larger (DIN A4 format) successor models B213x (1999) was the touch-sensitive 10.4" TFT screen and the input pen.
The E series usually has a high-quality, high-contrast 15/15.4-inch screen that is specially designed for office use, since no reflective displays are used and 4:3 formats are mostly available.
This series is particularly optimized for mobile operation, which is why only ultra-low-voltage processors from the Intel core architecture are used, the main memory is soldered and two batteries with a runtime of more than 10 hours can be used.
The performance is roughly comparable to the E series, but the construction is a bit lighter and the notebooks are smaller due to 14/13 inch displays.
Today (2017), powerful notebooks that are light but not extremely small are sold in the series, which usually have a 13.3 or 14 inch screen diagonal (U747, U757, U937).
