macbook pro running slow after a few minutes

[cnks]

hello. firstly sorry my english. i pilled water on my macbook one year ago. but just the part of trackpad. then i removed the battery and used the computer without it. computer started not recognizing wifi and bluetooth. i used the macbook like a desktop for one year.

for 3-4 months, it started running really slow. but main point it runs slow after 2 minutes. i open it then i can use it normally for 2 minutes. but then it runs slow again. if i close and open again i can use normally for 2 minutes again. what is the problem? i think it is not about a program or something like that. because hdd is empty and there is not any "hard" program. and i installed the os x again.

The problem is likely damage from the water spill. Water spilled on your MacBook one year ago has probably resulted in corrosion on the logic board and components. It's time for a new MacBook.

i thought like that but it doesn't run slow always. just after 2 minutes it runs slow. before 2 minutes i can use it normally without any problem. wouldn't it always be slow to run if there was a hardware problem?

How much can you do in 2 minutes? Spill damage can show up long after the spill occurred. And a water spill will cause corrosion to the logic board and components. Who knows what's happening after the initial 2 minutes? With all the problems you stated above, it's definitely time to think about a new MacBook.

I also had a hot tea spill on my macbook pro. Result was the same as yours: fans were revving and wifi/bluetooth/screen glitching. So i checked activity monitor, and it looks like CPU was stalled at 99% usage because it was trying to fix lost signal from wifi/bluetooth. So it was acting like that for 2-3 weeks and now it is normal at all except that Bluetooth is not working.
I would say that extracting airport card should help you. And maybe you could replace it if u want.

I am also pretty sure that a MacBook will be much slower without a battery in it. It does not matter if you have the MacBook connected to a power source. As long as the battery is missing it will throttle. So maybe this is the case for you. (This could also explain the 2 minutes as the MacBook may double check if there really is no battery and then start throttling - but this is just speculation on my side).
