You are looking at a lightly used, barebones Acer Aspire 9410z 17" Laptop computer, with Windows Vista code for activation on the base. This laptop was tested with universal power supply (not included) to boot to the BIOS as pictured. Includes a Pentium T2060 1.6ghz processor, 1GB ram, and no hard disk. Some keys on the keyboard stick and are difficult to press/register on the computer. This is the extent of testing of this particular unit. Please purchase it knowing that it will require some parts/repair to be a functional unit.
