Guys I bought good used yoga 2 13 from e bay for 240 last year. Laptop is good but I need stronger cpu and gpu I was wondering is there any change I can upgrade motherboard if other versions fit ?
You need to discover what socket the CPU is in.
If it is a BGA socket, you are 100% out of luck.
Something else, you can maybe change it, within a small range of other CPU's.
So...what CPU and socket do you have?
