This is a model from around 2012. It has a built-in Blu-ray drive. The HDD has been low-level formatted, and a clean installation of Windows 10 has been performed, with Windows Update up to date. All device drivers are installed. Office software and DVD playback software are not included. Battery life cannot be guaranteed. The AC adapter may not be the original for this model. It powers on, but it sticks out slightly when plugged in. The exterior is in fairly good condition. There is no fading of the keyboard characters. Accessories include only the AC adapter. It is not compatible with Windows 11. Given its age, the performance is quite sluggish, but it might still be usable if you upgrade the memory and replace the HDD with an SSD, so how about considering it as a customization base?
