sent to dell several years ago claimed water damage refused repair. Would not even post back then. now several years later it will post but NVIDIA graphics and external HDMI not working. Will run Linux but windows will not load (acpi bios error) have loaded newest bios set it to factory defaults and used dell recovery img still not working with windows. changed memory not change. have inspected internal components not corrosion or water damage seen. looks almost factory new. The intel graphics works on this machine. not load ing windows is fine but would atleast like to see the hdmi port working and nvidia working
