Macbook is setup to hibernate immediately, but it hibernates after ~1hr delay both on AC & battery

I tried to change the settings to all sorts of scenarios, but the laptop just refuses to hibernate right away. I want it to bypass sleep/standby completely, and cut off power to RAM immediately (hibernate). I tried setting sleepdelayhigh/low and autopoweroffdelay to 0, with standby and autopoweroff to 0. Didn't work. Then I changed standby and autopoweroff to 1, but with 0 delay seconds. Again, didn't work. Then I decided to change the delay to 60s. Didn't work. I also experimented with hibernate 3 and 25. It goes into hibernate after about 1 hour and I don't understand why it stays in sleep mode for so long. Another problem that I have is I setup displaysleep to 5 mins with auto sleep to 30mins, but every time the display is switched off, it goes immediately to sleep. Insane! I had to go back to 15mins. This is what I have right now, but like I said, it just doesn't hibernate after 60s. Neither on battery nor on AC. standbydelaylow 60 standby 1 halfdim 1 hibernatefile /var/vm/sleepimage powernap 0 gpuswitch 2 disksleep 10 standbydelayhigh 60 sleep 15 autopoweroffdelay 60 hibernatemode 25 autopoweroff 1 ttyskeepawake 1 displaysleep 15 highstandbythreshold 50 acwake 0 lidwake 1
