Laptop purchased around 2018. The display and touchpad are good, though it shows some signs of age. All keyboard keys work normally, except the F4 and Shift+C combination does not work (the C key works fine individually). The original battery has been replaced, which gives about 2 hours of backup on light usage. A cooling fan has also been replaced with a new original fan. CPU, GPU, Wi-Fi 5, and all ports are functional. The built-in speaker and microphone do not work, so a FONENG M1 Bluetooth Speaker will be provided with it. There is a facility to install an M.2 NVMe SSD. Thermal paste has never been replaced. Original Windows 10 is installed.
