This is a Panasonic Let's Note, known for its robustness and reliability! Despite being a 12.5-inch model, it boasts Full HD resolution for incredibly sharp visuals. While Windows might feel sluggish, it runs Linux Mint, a particularly popular distribution! It has two batteries: one built-in and one removable! However, there is some degradation, so please check the images. An AC adapter is included, but it's from another model, so please be aware of that. Furthermore, the speakers on this model don't seem to work well with Linux. If you play something like YouTube without any adjustments, no sound will come from the built-in speakers (headphones work fine). Regarding sound, it seems you can get it working by running a command while the system is running.
