Before tweaking for performance, let’s break down the exact hardware this laptop ships with.
The ES1512 features a matte silver finish (often dubbed "Iron Gray" or "Silver"). It utilizes a plastic chassis, but Acer has managed to keep the weight under 1.8kg, which is relatively light for a budget 15-inch laptop. The cooling system is usually quiet, utilizing a single fan and dual heat pipes, which is sufficient for the low-power U-series CPU. acer es1512 ms2394 specs best
