Before you start: Shut the laptop down completely, unplug the charger and peripherals, and hold the power button for a few seconds to discharge residual power. Use a plastic pry tool (not metal) and keep track of screw locations.

Opening the bottom panel

Remove the 13 Torx T6 screws that secure the bottom cover.
The panel is also held by clips. Use a thin plastic pry tool to work around the perimeter and release them gradually.
Be careful around the heatsink/radiator zones—avoid pushing the tool too far inward to prevent accidental contact with fins or small components.

Internal layout overview

Once inside, the layout is service-oriented: cooling hardware at the top, the motherboard centrally placed, and the battery spanning the front edge.
Most upgrade points are accessible without removing the cooling assembly.

Cooling system

The thermal module uses two fans and a large shared heatsink assembly over the CPU and dGPU.
Multiple heat pipes route heat into fin stacks for each fan, supporting sustained gaming loads as long as the vents are kept clean.
For routine maintenance, clean dust from the fins and fan intakes periodically; hold the fan blades in place if you use compressed air.

Storage upgrade

You get two M.2 slots for PCIe 4.0 x4 NVMe SSDs.
The primary slot in our unit is populated and sits under a protective cover that also acts as shielding; reinstall it exactly as found to preserve EMI control and SSD thermals.
The second M.2 slot is open and ready for expansion, making a dual-SSD setup straightforward.

Hint: If you’re choosing a new drive, you can cross-check options in our Top M.2 SSDs Performance Rankings.

Memory upgrade

Memory is user-replaceable via two DDR5 SO-DIMM slots.
Our configuration has one slot occupied and one free for easy dual-channel upgrades.
The platform supports up to 64 GB total and memory speeds up to 6400 MT/s (final speed depends on CPU support and module selection).

Wireless card

The Wi-Fi module is socketed and replaceable. This series uses a Killer Wi-Fi 6E AX1675i card.
To swap it, remove the single retaining screw, then lift the antennas straight up and press them back down cleanly during reassembly—misaligned antenna seating can reduce signal quality.

Battery removal

The laptop uses a 4-cell lithium-ion pack rated at 90.61 Wh typical (88.03 Wh nominal).
In our unit, the pack is not held down by visible screws; once you disconnect the battery cable, it lifts out without additional brackets.
Always disconnect the battery before upgrading RAM, SSDs, or the wireless module.

Reassembly checklist

Confirm the SSD shields/covers and thermal interfaces are seated flat.
Confirm SO-DIMMs are fully inserted and latched.
Confirm Wi-Fi antennas are snapped on and routed away from fan blades.
Reconnect the battery, then press the bottom cover around the edges until all clips engage.
Reinstall the Torx screws evenly—snug, not over-torqued.

Summary: The Predator Helios Neo 18 AI (PHN18-72) is easy to maintain, with straightforward bottom-cover removal and direct access to the two DDR5 SO-DIMM slots, dual PCIe 4.0 M.2 bays, the replaceable Wi-Fi card, and the high-capacity battery.

Acer Predator Helios Neo 18 AI (PHN18-72) in-depth review

The Acer Predator Helios Neo 18 AI (PHN18-72) defies the stereotype that 18-inch gaming laptops have to be thick, cumbersome tanks. It arrives with a surprisingly svelte profile (it's 14.9 mm / 0.59" thick at the front!) that houses serious firepower, including a high-wattage RTX 5070 Ti. This machine aims to deliver the best of both worlds: the immersive, expansive screen real estate of a desktop replacement, packaged in a chassis that doesn't require a forklift to move. But has Acer sacrificed too much performance to achieve this slim design, or have they struck the perfect balance for b[...]
