Is it worth disassembling keyboard from front-cover to fix 2 keys?
My kid spilled a cup of tea with sugar on wife's Air. Now it doesn't charge with it's own charger (14.5V, 3.1A) but it does with macbook pro's charger (18.5V, 4.6A). This is weird. Our local "certified" reseller (we don't have Apple Store in out country) suggested to avoid fixing it, since they could not identify the problem. I think they're lame but I'm ok with uncomfy charging. But there's still 2 keys not workng. The comma and period keys. These are quite important and used very frequently. Resseler suggested to replace keboard, but €250 is a bit pricey.
So what I was thinking — to get them fixed by myself. This is apparently circute closing, which in theory is easy to fix. I have experience disassembling our mid 2011 Air. Not the keyboard, but I did clean the logic board and most of other compartments.
What do you think? Is it worth disassembling the front cover from the keyboard and fix it? Are there any downfalls assembling it back?
Another idea I had is to wash the I/O board. I thought that if I could wash it in fresh water it would remove the left sugar out of the connectors. Sounds a bit ridiculous, but what do you think? :)
Notes: it does turn on, it works, just doesn't charge. Actually charging became unstable. I now cannot charge it with charger that I used just 10 mins ago, the one 18.5V.
