Toshiba HP ProBook 4520s. Intel® Core™ i3-M350 2.26GHz Memory: 4GB SSD: 120GB 15.6 inch (1,366 x 768 dots) OS: Zorin OS 18 (Core). This PC was used at a company with Windows 7, then Windows 10. However, due to the high system requirements of Windows 11, Windows 10 was erased and ZORIN OS 18 was installed. The operability is very similar to Windows, and even those who have never used Linux can use it intuitively without feeling out of place. Web surfing also runs smoothly. This is a good item for those who want to try moving away from Windows but don't want to touch their current PC. Software can be installed from the ZORIN OS 18 standard software menu. I installed Google Chrome from there and confirmed its operation on YouTube. It works very comfortably. There are some scratches on the top panel, palm rest, power switch, etc., due to use, but it is in good condition. Battery operation was confirmed. DVD playback was also confirmed. An AC adapter is included. *The password is set to USER. Please check the photos for other details.
