Tested and working laptop. I7 2920XM, 16gb RAM, 500gb ssd and 500gb hdd, GTX 560M. Was disassembled and both fans cleaned, new thermal paste, and new thermal pads. Item shows wear.Backspace key is very loose, c key doesnt work. Cant confirm functionality of ALL keys, but during my testing, most worked. Cmos battery holder is broken and does not hold cmos battery. As a result, everytime you boot it will throw a beep code. Boot it again and it works. In bios you MUST change the sata operation from RAID to AHCI. If you do not, windows cannot load.Windows hasnt been activated, battery holds a charge but is weak.Will answer any questions
