I woke up this morning and opened my macbook to see water all over the screen and keyboard I must have accidentally spilt a glass of water over my macbook pro the night before without noticing! Straight away I dried it off with a towel and left it to dry out for about 12 hours. I then turned it on and everything was working, apart from the trackpad which was slow to respond and right click didn't work. I connected my external trackpad from my iMac and it worked perfectly. I was planning to get a replacement through Apple as I still have 1 month left on the warranty. If I don't tell Apple it has water damage, would they be able to replace it still? Are there any water sensors in the Macbook like there are in iPhone?
