Re: need help to upgrade lenovo z51 - 70 RAM

Hi theuser1 , 


Welcome to the Community Forums.


Ram specification as per hardware manual page 28:


DDR3L-1333 MHz / 1600 MHz SODIMM × 2 (max 16 GB)


Lenovo Service Center are tied to the original parts that came with the warranty .

Upgrade parts holds it own warranty depending from where you purchase it . 

Upgrades should not void the warranty as long as such changes would not damage the machine during and after the process. 


More about how warranty works on upgrades  :


As a general rule , from the hardware manual under Part Listing CRU (customer replaceable parts ) are ok .

However most upgrades on this model shows that such are considered FRU (field replaceable unit page 94-95 item 11 for recommended ram ) , meaning you would have to open up additional parts and might require skill and specific tools (CRU ID. N). We had same issue discussed on this thread " Similar to this query is this case  for the Z500 replacement of optical drive which is also a CRU Id - N and this thread


Warranty agreement :


What this Warranty Does not Cover 

- failure or damage resulting from misuse, abuse, accident, modification, unsuitable physical or operating environment, natural disasters, power surges, improper maintenance, or use not in accordance with product information materials 

-damage caused by a non-authorized service provider

-failure of, or damage caused by, any third party products, including those that Lenovo may provide or integrate into the Lenovo product at your request


For best measure , you may give Lenovo Tech a call so that they would be able to note it on your account for the pc that you have plan for upgrades as warranty condition may differ per location.


Hope this help answer your query.
