The HDD has been replaced with a 120GB SSD. Because the memory has been upgraded and the SSD has been installed, it should run smoothly without stress for everyday tasks. USB has been tested and confirmed to work, but Thunderbolt?, CD tray, and SD card slot have not been used, so they are unconfirmed. Also, the power button sometimes requires a firm press to respond. The power cable is from a different model. The exterior has age-related scratches and scuffs. Please understand that this is a used item. Thank you for your interest.
