After putting it to sleep and making sure the LED in the front of the computer was NOT pulsing (i.e.
By doing this I was able to force safe sleep to happen without waiting for the battery to be drained. Where, setting hibernatemode to 1 tells your mac to always go into safe sleep. I learned a new terminal command to force the computer to always go into safe sleep. Now, I needed the Mac to go into "safe sleep" which is challenging, because normally this would only happen if the battery was completely depleated. I decided to delete the file so that it would get re-created the next time the Mac was put to sleep. I had read that any time you put your mac to sleep the sleepimage file will get created, if it doesn't exist already.

I proceeded to re-seat the RAM and run a RAM diagnostics test ("rember" from Kelley Computing, ), the test passed.

the battery went completely dead while the computer was asleep, causing it to resume from the sleep image file when power was plugged in) when I would bring it out of safe sleep it would make it 50% through the resume process and then I would get 3 tones/beeps separated by about 5 seconds and then repeating the same sequence.
