Toshiba Satellite C50 / C50D / C55 / C55D Memory Replacement Procedure


  • To avoid the risk of electrical shock, turn the computer off and remove the AC adapter from the electrical outlet.

  • Because the battery in the computer is left charged, the risk of electrical shock remains even after the AC adapter is removed from the electrical outlet. To avoid the risk of electrical shock, be sure to remove any metal jewelry or accessories such as necklaces, bracelets, and rings before starting work. Never work with damp or wet hands.
