T440p keeps shutting off. Particularly when I start a game.
What I've tried so far:
Replace fan/heat sink.
Replace i5-4210 with i7-4700mq.
Thermal gel properly done.
Tried four different brands of RAM.
Installed MS Office 2013, and .NET framework 4.5 Both run without a hitch.
Installed The Sims2, and it kicks off on launch. Same thing with Mass Effect 2.
Still kicks off.
It will run all day surfing the internet, running office, etc.

sounds like overheating. Can you install something to monitor temperatures, like TPFanControl?
Also, it works differently with no battery. You should get one.
Do you have discrete or integrated graphics? What is the rating of your power supply?

1) When you changed CPU for i7, did you replace your power supply or you still keep 65W adapter? If you have a model with nVidia graphics, insufficient power supply can be your problem.
3) Run "Lenovo - Updates and Drivers" from Control Panel to update all drivers
4) Run "Lenovo - System Health and Diagnostics" from Control Panel and run full test
Please post your results here for comparsion with other users.
My setup is T440p with i7-4700mq (upgraded from i5-4300), 16GB Kingston HyperX Impact 1600MHz, integrated graphics, Windows 7, 135W adapter (upgraded from 65W) and I run it without problems, even the temperatures sometimes reach 98°C.

My PS is 90w
I have a battery. Computer kicks off at start up with battery installed. Take battery out, starts/runs normally, until I try to install a large program, or run a game.
CPU fluctuates from 46c to 70c, depending on what I'm doing whether it's running the i5, or the i7.
HD4600 Graphics, no nVidia.
Win7 Pro, and WinX. Kicks off with both.I
I'm beginning to think the MB isn't the best
have latest drivers from Lenovo website.
I do not have those control panel options.

I cant recommend pulling the battery out, there is no reason for it!
Did you tried the test?
12-12-2017 11:35 PM
I don't pull battery out with the computer running!
Shut down, unplug PS, THEN unplug battery.
I also have to unplug the PS, and battery, and discharge the computer, before it will start again.

I ran the heat test with the recommended testing software. 46c to 70c Both i5, and i7.
It is not overheating.
I've been working on laptops since they came out. Gotta admit, this one has me a little stumped.
As a matter of fact, I'm watching You-Tube videos on it as we speak.... Seems to be working fine.
I'm wondering if the on board HDD controller is going out. Seems like the only time it craps out is when the battery is plugged in, or doing something that's disk intensive. Video's are running fine.
