Spilled drink on keyboard, had to replace upper case.

我的问题

Accidentally spilled my drink on my laptop, which rendered my left Return key, left Shift key, and the Z key non-functional.

我的修理方法

Not too bad. It was slow, but I made sure I had great lighting, the right tools, moved carefully and slowly, and read everything carefully before doing anything. I've bricked an old iPod by not making sure to follow those tips.

我的建议

As I said, go slow, be careful, and work gently. Absolutely get the right tools and read everything before doing anything. Keep an organized workspace and make sure you can see everything clearly. Get a magnifier or extra lighting if you need it. Work without interruption.
