I would recommend you to contact Lenovo for further assistance since this is an OEM system and we do not know if this kind of modification are supported or not.
Sometimes, if you make changes on OEM systems, the product is not going to be covered under warranty anymore.
hi sylvia, thanks for your answer.
i dont care for the warranty cuz is only 6 months (lenovo is not new)
do u know to tell me if both laptops will support both CPUs, as is search i see than lenovo have hybrid motherboard so if the socket is BGA maybe can support rPGA but acer?
you may think why i want to buy this laptop very much? believe me i find it in very good deal, almost 300 euro less than normal price...
if u can find something more than me please tell me, i search almost a weak and i dont xD
Thanks again for your time, i really appreciate it.
Since this is an OEM system there is no much we can or suggest you to do.
Again, I recommend you to post your inquire to ACER or LENOVO communities.
