In this educational video I will disassemble and upgrade the Toshiba Satellite C855 laptop CPU or Processor from an Intel i3 2nd gen to an i5 3rd gen processor next I will replace the HDD with a SSD and replace the 4GB DDR3 RAM with an 8GB DDR3 RAM memory.
I had to also remove the CMOS battery the keyboard and unplug the touchpad and power button to continue going inside the laptop and replace and upgrade the hardware parts inside.
I will also clean the CPU fan and remove the old thermal paste and add fresh one at the end I will also install a fresh copy of the Microsoft Windows 10 Pro operating system.
Thanks for watching and have a great day hopefully this helped you out.
