I have a Toshiba Satellite P755-S5215 Windows 7 Home Premium. My niece spilled juice on the keyboard. I opened the memory slot and hard drive covers and everything seems to be in tact. Is this a memory problem or what? Do you think the circuit board needs to be replaced. Should I take it to the geek squad at best buy. Do you think it's worth my time or should I just sell it for parts?
