People have an i7 in my laptop
and in my pc an i3 wanted to ask if i could install i7 in the pc.
If so, what should I watch out for?
Usually no, many notebook cpus are soldered onto the mainboard
If this is not the case, the base must also fit…
It may also be the case that your Desktop i3 is even better than your Notebook i7
Would only work if the notebook CPU was socketed and not directly soldered and if your PC and your notebook have the same processor socket.
In all other cases it is not possible.
Unlikely. I've seen motherboards that can hold notebook CPUs. But that was in Core2Duo times, or something like that. So it probably doesn't work
This will not work. The processor from the laptop is usually soldered. In addition, the desktop board will not support the mobile processor.
