This article provides step-by-step instructions for safely accessing the SSD, RAM, and CMOS battery on 15-inch Elo E-Series 3 systems with Intel processors.

Upgrading the SSD or RAM can improve storage capacity, speed, and multitasking performance. Replacing the CMOS battery may be necessary for system maintenance or to resolve hardware issues. This procedure is sometimes required for troubleshooting or routine servicing. However, it should only be performed by qualified personnel—improper handling may void the warranty or damage the device.

Note: Following this procedure improperly may void the IP rating or damage the unit. Handle with care.
⚠️ Important: Damage sustained during this process is not covered under Elo's warranty and may void the manufacturer's warranty.
