Issues with battery and fan
For several months my battery has not been charging or holding a charge as it should. Within a few minutes it drops to 0%. So I always have to have the power cord plugged in.
Then within the last month or so my computer makes a loud buzzing noise. It sounds as if the fan is running on high speeds. This occurs even when I have nothing running. And I usually have to wait a while before starting up my computer again to avoid that noise on start up.
I just recently checked under "About this Mac" - and it says my Hard Drive is verified but my battery is in poor condition and has had 722 charge cycles. Which I believe is way over the typical life span of a battery.
To elaborate - the noise is not a high blowing noise but more like a high speed buzzing noise. And it comes from the top right of the keyboard.
Being that I probably would have to replace the battery anyway - should I first see if that will solve the problem? Since maybe the fan and cooling system is trying to compensate for an all but dead battery?
Or should I have Apple take a look at it and see what they say? Do you think it's more serious than the battery?
P.S. I've already tried resetting the SMC - it didn't work.
Thanks in advance for your help!

Okay I bought the battery today - but I just want to verify that the current MBP 15 in batteries will work without any trouble with my older MBP 15 (from 2008).

So I've been using my computer with the new battery. The one improvement is the charge lasts as it should. But I still get the noise from the top right of the keyboard. It typically starts off as a low humming/buzzing sound and then eventually kicks into a loud buzzing noise - no matter if I am an application open or none. Even if I walk away from the computer for 20 minutes I will come back to the loud noise. Sometimes if it falls asleep it will make the noise or I'll go to wake it up and it makes the noise.
Any suggestions before I take it to Apple?
