Ok so my friend has a 13" MacBook its model identifier is 4,1 the machine is a little older then 4 years. And has been used primarily for web browsing. Now apparently he used some sort of cleaning *cloth* on the keyboard area because it was dirty. I'm not sure what was on the cloth but it was one of those kinds that have some sort of liquid on them. So then when he went to go use it it was black and when it was powered on it was letting out a *BEEEEEP* every few seconds until you shut it down. Now I've went underneath and unplugged the battery and hardrive plugged them back in after giving it a second and when powered on had that same beep going. My guess is that since it was used around the keyboard area it wasn't the hardrive or the battery that got damaged but the CPU or a circuit. I've never ran into this beeping issue in all my days as a mac user but could really use some help for my friend. Thanks EDIT: I've looked around some more and people say that the certain amount of beeps indicate certain things. Well the laptop went all the way up to 7 before we turned it off again and from what I understand it only goes to 5 if it means something is wrong with the ram/hdd/cpu.
