No charge after water damage
A few weeks ago my laptop got wet, so I put it in rice for 2 days and it started working again. A week later, it will no longer charge, but the laptop flashes on but will not turn on because it has no charge. I've set it in rice for the past 2 days to see if it would help anything, but nothing has worked. I've taken the back off of the laptop but am not sure how to disassemble it further.
