The ExpertBook BR1104CGA budget educational laptop from Asus impresses with long battery life, as well as silent and cool operation. It might not be the fastest educational laptop out there, but it offers a good price / performance ratio at under-400 EUR.https://www.notebookcheck.net/Power-efficiency-champ-Asus-ExpertBook-BR1104CGA-educational-laptop-gets-the-Intel-N100-treatment.844198.0.html
For that price far better choice are used HP EliteBooks or Dell Latitude laptops. Situation with ASUS showed clearly that RMA especially with anything produced by that scam company is a complete joke so better to buy anything that is little older but much more solid from HP/Dell.
