There are lots of Android OS that support laptops like LineageOS, chromeOS, primeOS, etc.
The most commonly used is usually ChromeOS and is even also available in the form of Chromebook Laptops with chromeOS that work within the Android operating system.
@OP can you provide the model and details about your laptop or take a picture of your laptop? Maybe we can check the specs online if we know the exact model of your laptop maybe we can help you how to install the Bitcoin node.
For the details of the model and specifications, OP doesn't seem to give any more answers.
But maybe it is some kind of Tablet or Chromebook laptop as the RAM embedded is only 3GB and internal 380.
If it's a laptop that dual-boots Windows and Android OS, then the laptop specs are still very minimal.
It may be an old laptop or tablet device that is available with Android OS with a physical keyboard button that is integrated and detachable.
