Troubleshooting for two old macbooks (one is 60 months old)
Resetting SMC
Remove magsafe power cord from macbook. Wait 15 sconds. Then press the power button for at least 5 seconds. Then reconnect the cable and turn on as normal.
Zapping PRAM
Press power on. Immediately hold down Command-Option-P-R. if you hold it down, the chime will play over and over again. after you hear the 3rd chime let go of the keys and let it go on as usual.
QuietMBP
Old Intel-based Macbooks may have a strange buzzing sound coming from the location of the Esc key. Put your ear to the esc key if you don't believe its coming from that key. Anyway running quietmbp will help make it less scary. It apparently is a sound emitted when cpu is "too idle". Is not related to hard drive whine.
