They don't even want to perform out of warranty, paid repairs if any of the liquid sensors are tripped. A few years back I had an MBP that the battery had worn out on, but several years before, I had spilled some water on the keyboard. The computer was none the worse for wear -- I dried it out quickly and it was fine, but when the battery wore out and I wanted it replaced, they wanted me to pay $1500 for a new motherboard before they would be willing to replace the battery.
