### ⭐ Computer did not work on arrival.

This computer was supposed to be refurbished. It was not tested. It does not work. Fan turns on, Power light turns on, that is it. It does not start the BIOS. IT does not talk to the screen. New M2 drive and new DDR5 memory.

### ⭐⭐⭐⭐ Buen rendimiento. Pequeño y compacto. Silencioso
*by A***O on November 11, 2025*

Llego todo bien en su caja cables completos. Calienta regular al trabajar al 100% . se instalo sus driver sin problemas. no da tirones al trabajar al 100% el procesador. 32gb de ram se llena súper rápido solo con navegadores y programas de edición abiertos. Y por el cual hace que el ventilador gire rápidamente y suene un poco. Recomiendo un ventilador de laptop para los días de verano ya que al trabajar al 100 % si bota mucho calor el equipo.
