So, yesterday, I dropped a full cup of tea (no milk) on my Macbook Air mid-2011 (yeah, those good ones) keyboard. I thought this time it was over, and daddy was going to have to get a new Macbook. I have the screwdrivers for the back and the battery (bought a battery off Amazon last year). So I went ahead and took the power cable out and opened the Macbook's behind. Took the battery out. Pointed a fan at it, and left it like that. A few hours later, I popped the power cable back in and tried to switch it on (the battery was still out) and lo and behold, it turns on. Unbelievable but true. Anyhow -- I've assembled the whole thing back together (with the battery). And I'm actually writing this on the very same Macbook. I do have one issue though. Please see the attached image. That's what my battery indicator is saying, and as soon as I pop my power cable out, the Macbook switches off. My question is: from prior experience, does anyone have any suggestions on what I can do about the battery (or is replacing the only option now)?
