Tested and working! Still usable! LIFEBOOK A577/S Touchpad and the two keys below the touchpad are unusable due to connector damage. Please use a mouse you provide. m(_ _)m Instead, I've added a WiFi card and antenna! WiFi card, 867Mbps Antenna, 5dBi 2.4GHz/5GHz CPU, I5-7200 Memory, 8GB x 1 Storage, SSD, 6Gb/s, 128GB OS, Windows 11 Pro Charger available for an additional fee! Storage and memory can be upgraded for an additional fee! For memory upgrades, I will purchase the memory. For storage upgrades (SSD replacement), I will purchase and install the SSD, and then reinstall Windows, so it will take a little time!
