Is it the motherboard or the battery?

Someone spilled chocolate milk on the really nice gaming laptop. We tried to quickly turn off the laptop, but it just stopped itself. I took it apart (cleaning up the chocolate milk of course), and carefully inspected each part. As far as I can see, the liquid did not touch the motherboard. The largest concentration of liquid was on the battery. I used alcohol (96%) to clean up the liquid. I also inspected the motherboard for broken or scorched areas, but everything looks fine.

Here is what I have tried:

1. Plugged in cord and attempted to turn it on.
Result: LED is lit up (orange color). Machine will not power on.

2. Left cord plugged in overnight (to charge the battery). Kept cord plugged in and attempted to turn it on.
Result: LED is lit up (blue color). Machine will not power on.

3. Unplugged cord and attempted to turn it on.
Result: No LED is lit up. Machine will not power on.

4. Removed battery, plugged in cord, and attempted to turn it on.
Result: No LED is lit up. Machine will not power on.

I have a decent knowledge of computers, so I understand the basic workings of a computer. I have limited funding, so I can't afford to buy something that won't fix the problem. My guess is that the motherboard is dead because plugging the power cord in lights up the LED and the color of the LED changed overnight, indicating to me that the battery was charged by the cord. Without the cord, however, the LED does not light up, so it could be the battery. Worse yet, it could be both.

I have an Acer aspire vx5-591g. Acer does not cover liquid spills in their warranty.

I also found chocolate milk near a contact for one of the wires (the big wide one that is taped to the battery). I cleaned that the best I could, but reaching inside was very difficult. I don't really have the proper tools.

My questions: Do you think it could be the battery? The motherboard? Both? Is there a way to find out without spending too much money? I have a multimeter, but I don't quite know how to read it.

Thanks so much!





 
It may need more time to completely dry out. Try leaving the back cover off with a fan blowing air over it.

You could also try unplugging the laptop, then remove the battery, next remove the coin battery powering the BIOS for 60 seconds and hold the start/power button for 60 seconds to drain any remaining power in the system. This may reset the BIOS. I don't know if that will help, but at this point you don't have many options left.
