[omair.mi.16]

How can i know if my Motherboard is able to be modified by Improving the CPU and the RAM, since i have got a FUJITSU laptop.
what should i look for at first? the Motherboard name, model... and where can i find these details? then how can i know what CPU and RAM is compatible with this motherboard that i have.
thank you so much for helping me

you said you have a FUJITSU laptop right, so a laptop?
and what do you mean by improving CPU and RAM? upgrading to a new CPU and RAM? RAM, you can, but CPU, no

You google model name of your laptop and look for motherboard images.
If cpu is in a socket, it can be changed. If it's soldered onto motherboard, then it can't be changed.
But you have to account for cooling solution also, so in reality cpu can be changed only to one that has ~ same TDP as original.
Compatible cpu will have the same socket and same generation (code name).
Compatible ram will have the same type (DDR3, DDR3L, DDR4) and form factor SODIMM.
