Acer Predator Helios 18 AI in-depth review

The Acer Predator Helios 18 AI (PH18-I71) is an ultra-premium, desktop-replacement behemoth engineered for hardcore gamers, creators, and extreme power users. The very first thing that strikes you is its colossal footprint, immediately followed by the stunning 18-inch Mini LED display - in our configuration, a razor-sharp 3840 × 2400 panel that can also switch to 1920 × 1200 at 240Hz when speed matters more than pixel density.During our review, we were absolutely blown away by its staggering upgradeability: four RAM slots supporting up to 256GB and three M.2 slots, including one Gen 5 slot, are a massive surprise in today’s laptop market.

Disassembly, maintenance and upgrade options

Step 1: Removing the bottom panelPower off the laptop and place it on a soft, clean surface. Undo the 10 Torx T6 screws securing the bottom panel. All screws are the same length, which makes reassembly easier. Use a thin plastic pry tool to carefully release the clips around the perimeter. Keep the tool shallow while prying, so it does not slide too far inside and touch the motherboard or internal cables. Lift the bottom cover away from the chassis.More info: The bottom cover has thermal pads and copper plates for the SSD area, including the empty upgrade positions,[...]
