Concerning the T440p and the T540p, this is information that I have put together concerning the heatsink/fan assembly. As you know the T440p has the same CPU and GPU choices as the T540p, so you would think that heatsink specs would be about the same for both models using Intel I7 cpu’s with 47 watt configuration along with the GT730m GPU. However, based on the images from the following links, it is easy to see that T540p (see the fan intake and exhaust ports images and service video’s) has a more robust copper heatsink/fan assembly which is likely similar to the W540 that is soon to be released.

Google Translate 2. ThinkPad T440p Service Training After reviewing many articles about the difficulties concerning cooling the 47 watt I-7 Mobile CPU’s with discreet GPU’s along with the fact that the link images that show the T440p has a dark colored plastic looking fan exhaust similar to the T440s and the Training Video does not seem to show a copper Heatsink, I can only conclude that in a T440p setup with a I-7, 47 watt CPU with a GT730m that I would want the same heatsink/fan assembly that the T540p has and not the setup that theT440s uses which only uses the imbedded Intel Ultra 15 Watt CPU’s. Please feel free to help me change (post some pictures of T440p Heatsink) my mind because I am trying to convince myself to purchase the T440p as it has a very nice FHD display that is actually the same FHD display used in the T440s (same part number). However, the T440p/T440s panels are not IPS panels but AHVA panel displays made by AUO (AU Optronics) which is okay because it is an advanced version of VA panel technology. Also, both the T440p and the T440s use the same panel part numbers (see the Lenovo PDF Parts FRU Listings on the provided Links above). Correct me if I am wrong but please carefully review the following links first. I do wish Lenovo would stop labeling the panels as IPS and use AHVA instead because IPS and AHVA are not the same.

Monitor Specifications T540p FHD DisplayPanel Information to consider: I was also interested in purchasing the T540p for the better heatsink/fan setup and the numeric keypad until I discovered that the FHD (1920x1080) panel used in the T540p is definitely a lower end TN panel. (See the link to the LCD Panel part number from the FRU Parts List) The specs on the 3K panel look good at a glance but I do not want 3K resolution because of the small text and the added power requirements leading to more heat(work the CPU and GPU harder) and lower battery performance. Please correct me if I am wrong as I would rather buy the T540p, but only if it had a high quality FHD panel choice.

INNOLUX N156HGE-EA1 Overview - Panelook.com Otherwise, overall, I really like everything else about both the T440p and the T540p a lot and the prices are better than HP’s Mobile Workstation (HP ZBook) prices when custom configured. The HP’s do offer a lot of Workstation features but it gets pricey. Questions 1. Any Thought about the above Info? Do you think the T440p should have a better Heatsink/Fan assembly(more copper) so that the system will last a long time like laptops have in the past? 2. Do think the T540p should have a better FHD Panel, IPS or AHVA instead of TN display technology? Don't you think they should list it on their website as a TN panel and that it is not the same FHD type panel used in the T440p?
