I'm working on a coworker's Sony Vaio model: SVF153B1YL. She stated that soda had been spilled in it. After taking it apart and inspecting the internals, I didn't find any corrosion on the MB. So I put it back together and took a few keys off; you can't access the keyboard from under the laptop, and I found what looked like soda under a few keys. When I went to turn on the computer to see if it would even boot, nothing happened. I tried to plug it into charger and it didn't seem like the battery wanted to pull a charge. My question is, how can I test the battery to see if it's dead, or even the board to make sure that it's live? Thanks in advance.
