Looking for a notebook with a long running time?

Does / does one have a notebook with a long running time? So under continuous load and not in standby or something… Most of the battery life of manufacturers is usually at standby… I've gotten one, where it stood up to 8h and under load, it was only max. 2h through

priced best under 400 euro, need only for Uni, so no big bells and whistles

Under 400 euro, there are few. Since you can manage with a spare battery such as a laptop power bank. In the higher-end segment, Microsoft's surface models such as the Surface Book, the Surface Laptop or the Surface Pro are ideal.
