My 13-week-old cat knocked roughly 12–16 fluid ounces of soda onto my Acer Aspire 3 laptop. The liquid went through the keyboard, and the speakers stopped working shortly afterward. The speakers were already unreliable, so I'm assuming they may need replacement.
I shut the laptop down as soon as I noticed the spill, positioned it so the liquid could drain, and removed the bottom panel to inspect the inside. Most of the visible liquid seemed to have reached the speakers, with a smaller amount near the battery and nearby components. I used isopropyl alcohol and a microfiber cloth to dab away sticky residue from the case, battery area, and surrounding parts.
What else should I do before trying to use it again? How long should it dry, and are there safe ways to clean the keyboard? I need this laptop to last through my final year of undergraduate studies.

Don’t assume it’s dead just because it doesn’t work immediately. Sugary drinks can cause delayed corrosion or short circuits, so drying alone isn’t enough if residue remains. Use isopropyl alcohol on accessible affected areas, keep the battery disconnected if you can, and test only after everything is completely dry. If you’re unsure about opening or cleaning it, a repair shop may be safer than risking the motherboard.
The speakers may be permanently damaged if soda soaked their cones. They can sometimes be replaced, but cleaning them without causing more damage is difficult. The more important thing is removing all sugary residue from the motherboard and keyboard and making sure there is absolutely no power connected while the laptop dries.
Do not power it back on yet. If possible, disconnect the battery from the motherboard, then clean any sticky residue with high-concentration isopropyl alcohol and cotton swabs. Pay attention to the keyboard area and connectors, but don’t scrub aggressively. Leave it open and unpowered for at least 24 hours; 48 hours would be safer before testing it.
I’m not confident I can disconnect the battery safely by hand, but I’ll look for a teardown guide for this model. I’m planning to leave it off as long as possible and ask my professors for extensions on the assignments due tomorrow.
The speakers were visibly covered in soda, so I’m treating them as ruined for now. They appear to be the main part that was hit, aside from some liquid around the battery.
