At least for now, you can choose between the 45W and highly clocked Core Ultra 9 285H and the 28W Core Ultra 7 255H. The latter has the same core count and cache size as the 285H chip which makes it a perfect choice for people who don't require top-end performance for everyday tasks and want to save some money.Both CPUs have the same iGPU under the bonnet and that's the Intel Arc 140T. This one is based on the Xe+ architecture. Just for comparison, the Intel Arc Graphics 140V inside the Core Ultra 7 258V is based on the Xe2 architecture [...]

Disassembly, maintenance and upgrade options

Step 1: Opening the ASUS Zenbook DUO (UX8406)Power off the ASUS Zenbook DUO (UX8406) and place it on a soft, clean surface to prevent scratches. Remove the 12 Torx-head screws from the laptop's bottom, including the one hidden beneath the kickstand. The kickstand is secured with two pairs of screws. Unscrew the two Torx-head screws to open the small service door. Detach the battery and the second display ribbon connector by flipping up its plastic cap before gently pulling it out. Use a thin plastic tool to pry open the zone around the second panel, starting from the ba[...]
