Alright so here's my situation, I just bought a Toshiba Satellite C55D-B102. Not the best laptop but it was a great deal. I want to know if I can upgrade the RAM and possibly the CPU, I've done a lot of research and I have found out that the mother board is the TOSHIBA ZBWAE. Toshiba says that the ram is not upgradable but it came with a 4gb stick and two slots which i find really dumb if you cant upgrade it. But i have no idea where to begin with the CPU it has an AMD A8-6410 with Radeon R5 APU running at 2.00 GHz.
