Hard drive installation instructions for
Predator Helios 300 laptops
This article only applies to: Predator G3-571, G3-572, G3-
573 and PH317 models.
The Predator Helios includes a storage bay that allows for installation of a secondary 2.5" hard
drive or solid state drive. If your system does not include the hard drive caddy for installing a
second drive, please contact Acer support.
Use the steps below to install a secondary drive in your system.
Note: Acer recommends use of an anti-static wrist strap when adding hardware to your system.
1. Remove the AC adapter and make sure your system is completely powered off.
2. Remove the screw securing the hard drive door to the lower case, and remove the door by
lifting at the cut corner.
3. Check to see if there is a hard drive caddy in the drive bay. Continue to the next step if
the hard drive caddy is in the bay. If there is no caddy in the drive bay, skip to the
Extended installation instructions section at the bottom of this article.
