How can I reset the service battery warning? I learned from one of my other questions that the "Service Battery" warning will limit your CPU power and slow your computer down - this is a problem I've been having with my MacBook Pro. 

I have 906 cycles on it but I'm still getting good life and unfortunately, I don't have time to go to get my battery replaced ATM since it's the middle of exam season for me. 

Resetting the SMC gets me going for a while with full CPU speed, but then it slows down again.

How can I disable this warning and get my computer back for the next week?
The bad news is you can not reset the cycle counter, it is a part of battery circuit. Your battery is at its end of life (EOL).

Temperature

How to keep battery running just a bit longer, keep it cold.

Do not have your laptop on your lap even if the name says so.

Go to your fridge and get one of those jelly-packs and put it under the laptop.

Energy Saving

Quit or disable any applications you are not actively using.

Dim the screen as much you can.
