Fundamental problem with laptop is that its memory is too small you need something above 4gb. or else it will just crash. if you managed to upgrade it to 8gb it would be usable
Considering desktop machine you can easily get it for very low price next to free specs do not matter, so main issue is not so much about money but whether you have space to keep it.


If you want to use your laptop so much you can do it at some extent, but you will be required to use 3delight rendering engine which output is not very realistic and to make things reasonably fast you will need to limit amount of light sources and avoid using complex structures like hair and you will have lots of other limitations.
It is real pain in the as in comparison to using decent machine where all you need to do is to set your scene add some HDRI environment and get great results without any effort


Here are some tests:
rendering only one naked genesi3 character with hair required 900mb in 3delight and 1800mb in iray mode
adding clothing increased memory requirements twice


reality or lux renderer have to be installed as separate plugins reality is essentially same lux renderer with complex gui
