Macbook Pro: Hibernate vs Shutdown I'm using a Macbook Pro late 2011, it has been upgraded with a SSD and 8GB RAM.
I was curious as to whether putting my mac on hibernation would extend it's life or I should just shut it down every night like a regular person...

**Problem: **I have to use this for an another 4-5 years.
**Usage: ** for like 3-4 days of a week, it runs for about 10hrs each day, it is mostly sitting idle.

I have a lot of stuff opened up and I use "Reopen windows when logging back". I just feel like the whole shutting down and booting back up puts excess stress on my CPU.

The CPU usages all the way to the top for like 5 secs on booting up. Would it be better for my CPU's life if I just used hibernation instead?

I could use this command I figure: 

sudo pmset -a hibernatemode 25
Interesting question. Computers have a measurement call MTBF or mean time between failure. The more parts something has, the shorter the period between failures. If the computer is off, then it cannot fail during that time. So you will extend the life of your computer by turning off the power when not in use. Hibernation is still on, and helps conserve battery power. Since your disk is not spinning media, shutting off power to it will extend its life. CPU failure will be due to overheating, so if the fan is not coming on when you boot, it is in no danger.
