G771 Upgrade Guide

You should be glad to know that you don't have to be computer savvy to upgrade G771 by yourself, and that's great news if you've always wanted to upgrade a PC.  Before you know it, you'll be building a liquid-cooling system with sound-activated bling.   You'll need a place to work where you won't be losing screws and scratching up the laptop surface.  Let's start here by opening up the back cover.  Just unscrew where indicated (red), then pull off the cover and now you have successfully voided your warranty, just kidding, if you follow this guide your warranty will be safe.  No separate compartments nor multiple screws, just one screw holds the cover securely (the screw is hidden under a rubber stopper which needs to be removed first).

 

Upgrading RAM

G771 has two SO-DIMM slots right in the middle.  If you don't get 16GB of DDR3L 1600MHz RAM pre-installed (two 8GB DIMMs) then it is possible to upgrade.  This uses DDR3L RAM which only requires 1.35V.  Just gently pull apart the latches (blue), and the RAM will pop up, allowing you to slide them out.  Obviously the top one needs to be taken out before you attempt the bottom one.

Voila! Remove the memory and you have a non-working system!  Now you can insert any new DIMM(s) by doing some reverse-engineering; insert the new RAM (it only goes in one way), and push down until both latches lock into place.

M.2 PCI-Express SSD

 You could get m.2 PCI-Express SSD pre-installed or you can upgrade by removing another cover located below the RAM.  In this model, there is an SSD pre-installed and secured by another screw.

Dual Upgradable Drive Bays

There are dual 2.5-inch drive bays on each side of the RAM.  In this model there is a hard drive in the first bay on the right, and the left, second bay is available for expansion.  These bays will fit any standard 2.5-inch drive, may it be a larger HDD, SSHD, or a pure SSD.

They use the standard mobile SATA connectors you can see below.

Upgrading the Optical Drive

In the unlikely case that you have maxed out both bays and the PCI-Express slot with storage and STILL need more, you can remove the optical drive.  Again, there is only one screw (yellow) needed to secure it, just unscrew and slide the optical drive out (as illustrated).  G771 uses a standard mobile SATA connector for the optical drive which allows you to easily upgrade it or use the bay for anything else. With a 3rd-party caddy that's a total of four storage devices possible.

 

 

Battery Swap

If you are going on a 12 hour flight or long gaming session without access to a power socket, an optional second battery could come in handy.  It is easy to lock and load, well, actually it is more like unlock (slide the locking mechanism) and reload.  No you cannot replace the battery with another hard drive...
