3. Installation Guide
Installing a RAM module requires careful handling. Please follow these steps to ensure a successful installation:
Safety Precautions:
- Power Off: Completely shut down your computer and disconnect all power cables.
- Static Electricity: Ground yourself before handling the memory module to prevent electrostatic discharge (ESD), which can damage components. Touch a metal part of your computer chassis before touching the RAM.
- Handle Carefully: Hold the memory module by its edges, avoiding contact with the gold connectors or the chips.
Installation Steps:
- Access Memory Slots: Open your laptop or AIO system's casing to access the memory slots. Refer to your system's specific manual for instructions on how to do this.
- Locate Slots: Identify the available SODIMM memory slots. If replacing existing modules, gently push the clips on both sides of the module outwards to release it, then pull it out.
- Align Module: Align the notch on the A-Tech SODIMM module with the key in the memory slot. The module should fit only one way.
- Insert Module: Insert the module into the slot at a 45-degree angle, applying even pressure until it is fully seated.
- Secure Module: Gently push the module down until the clips on both sides snap into place, securing the module horizontally.
- Close System: Reassemble your computer's casing and reconnect all power cables.
- Power On: Turn on your computer. The system should automatically detect the new memory.
