Which laptop Microsoft max. 400 euro for office work and microsoft teams meetings can you recommend?
No special performance is required for this. I would look around the used market and look for a Lenovo Thinkpad T series.
There are various dealers who sell remanufactured leasing returns with a guarantee.
This one here:
LincPlus laptop 14 inch Intel Celeron N3350 4GB RAM 64GB eMMC expandable up to 512GB by SSD thin metal with Windows 10 S notebook, QWERTZ DE keyboard Ultrabook https://www.amazon.de/...07MLFD19X/
For 30 euro more I would recommend:
https://www.cyberport.de/?DEEP=1CA2-027&APID=14&iaid=20200426124312540992b5eaf1253c
Has only Win 10 S (no EXE programs executable, only MS Store software) and 64 GB mass storage.
The CPU is also not a hit, but it is enough for Office.
It also costs 00 euro
If you could wait a few more days for the device, I would recommend the following device: https://www.cyberport.de/?DEEP=1CA2-02C
It is a 15.6-inch device with a full HD display. An AMD Ryzen 5 3500U, 8 GB RAM and a 256 GB SSD are installed.
Would be enough for your projects.
If you need the device faster, then this one: https://www.easynotebooks.de/Notebooks/Hewlett-Packard/200-250-255-350-355/231058/HP-250-G7-silber-2D197EA-ABD-15-6-FHD-Core-i3-8130U-8GB-RAM-256GB-SSD-DVD-LW-FreeDOS
The size of the device, the resolution, the amount of RAM and the size of the SSD are the same. Instead of the Ryzen 5 3500U, an Intel Core i3-8130U is installed, which has less power but is also sufficient for your requirements.
Just don't.
Are both without an operating system, a problem for the non-experienced user.
Would generally take the i3 for the purpose, for the purpose of power consumption (and thus also battery)
Yes, if you want an operating system, your recommendation would probably be a better choice. If not, you could save another 10 - 15 euro here and would have the device faster ^^
