Hello I noticed that my boot times are heavily impacted by whether my laptop is plugged into the AC power or not. Is there a way in power manager to force full performace at boot time so that I get my fast boot times off battery also??
thanks a lot for the help guys.

Can you please be more specific? HDD or SSD for boot drive? A boot time of 2 1/2 minutes is not uncommon with the HDD. Do you have RapidBoot installed (1.20)? Are you running the factory preload?

I'm using SSD and playing around optimizing my boot time. Yes I do have Rapid boot. I vary about 10 - 30 second difference when off of AC
I figured that I can change my power manager settings to "turbo performance" when off of the AC power, however what I would like to know is if there is anyway to enable Turbo or maximum turbo performance TILL boot is over and then bring it back to a balanced plan to conserve battery life. OR I would also be happy with having maximum turbo the default setting until say 50% batter has been depleted and then change the plan to balanced??
Is power manager accessible from command line? If so I could write a task to change the settings on an windows event.
Thanks for your help!

Remove RapidBoot if you are using an SSD. There's no value in the software for your configuration. There is a parameter in the BIOS that can set performance levels on AC and Battery. Access the section and set to maximum performance for both and then see if your battery times are better. Also, I assume that you have the Display set to Optimus so that the boot will not be using the GPU. The system will limit CPU performance if the NVIDIA GPU is used on battery.
BIOS level? I assume at least 1.36.

Rapidboot is useless for an SSD? How so?
And thats a great idea I didn't even think about changing the bios settings! How does the lenovo powermanger vs bios setting to maxium work out? How will this effect battery time?

that was a great suggestion!
To anyone with an SSD optimizing for boot speed setting the intel speed for maximum performance is a huge help. I now have that set to maximum, thermal set to balanced and my power manager setting set to balance. I feel like this is the best of both worlds.
Is it better to remove rapid boot however?

Yes, RapidBoot has virtually no effect (and some poor effects as well) when booting from an SSD

Is your boot time of 23 seconds from power on to login screen? I am using a SSD and it seems that the bios alone takes 15 seconds of my boot time up, so I would have no clue how to get such a quick startup.

Yes 23 seconds from boot into login then about 12 seconds for startup. I've done a lot for this because I'm a loser with a new laptop :-p
Basically - i tested myself superfetch all the way off leads to best performance
Msconfig - no startup apps sep necessary drivers - i use a program called aquasplash and MSE
Services - don't mess with these because it caused more issues then not
Pagefile - I have 16gbs of ram so Iset my page file to 512mb min and 1024 max
Hibernation file - set the hibernation file to 50% of it's capacity - done through the command " powercfg.exe /HIBERNATE /SIZE 50 "
I also downloaded CCleaner which is accessible through command line. I set my options dictating what I want to clean - and then drop a copy of the ccleaner.exe into system32 - I then create a logoff task in group policy running ccleaner on every logoff therefore on every log in system temps and cache and any garbage is no longer there.
Those are all the tips I can think of right now.
