We recommend using a desktop (tower) PC with FOVE, but is it is possible and supported to use laptops.
If your laptop meets spec (see What are the minimum PC requirements of FOVE 0?), then you will have enough power to run FOVE.
The main problem with laptops, besides often being underpowered, is that they typically have two GPUs: The "integrated" GPU (contained within the CPU), and a "discreet" GPU. Laptops with NVIDIA Optimus technology are the most common form of this.
Although there are two GPUs, there is typically only one HDMI port, and thus only one GPU is directly connected to it on the mainboard. If the discreet graphics card is not the one connected directly to the HDMI port, then FOVE will not work.
Some very high end laptops have hardware muxers that allow both cards to access the port, but in most cases, only one card is connected and if it's the wrong one, it wont work. Worse, this information is typically not written in the spec-sheet, so we recommend testing before you buy, if you can.
Any laptop advertised as VR-ready will work fine. We've found that most, but not all laptops marketed as gaming laptops also work, even when not specifically advertised as VR. Non-gaming laptops typically do not work as they typically don't even have a discreet GPU.
If you purchased an Optimus laptop, you should set the discreet GPU as the default GPU in the NVIDIA Control Panel before using FOVE to ensure that all applications use the correct GPU. The FOVE Compositor will search for the correct GPU at launch, but some applications, including Unity-based applications, will just use the default.
Below is an example of a laptop that is not functional with FOVE, because the Intel GPU (instead of the NVIDIA GPU) is the one connected to the laptops HDMI port. (Note that PhysX is unrelated but it's pane in the NVIDIA Control panel has a useful visualization).
Below is an example of a laptop that is functional with FOVE. Note that the FOVE display will not show up as connected like the monitor does (this is intentional for "Direct Mode" so that Windows does not take over the screen).
One final concern is that many HDMI adapters don't function with FOVE, so we recommending finding a laptop with an HDMI port. If you must use a DisplayPort<->HDMI adapter, make sure to get an "active type" adapter of good quality. We use this one.
