This laptop has been completely gone through. The operating system was freshly installed and updated. I updated bios and drivers as well. I cleaned the heatsinks and applied new thermal paste. Fully checked for function of all ports and devices. This is a good laptop for general everyday use. If you have any questions, please feel free to ask, I am happy to answer what I can.
