Questions about this item

How loud or hot does the 10-core i7-1255U get during all-day workloads?

The 10-core processor runs at a 1.2 GHz base frequency and can boost to 4.7 GHz, while the integrated Iris Xe graphics share the same thermal envelope inside the 0.83-inch chassis.

Which cables or peripherals must I already own to use the video and data ports?

The laptop provides two USB 3.2 Gen 1 Type-A ports, one USB 2.0 Type-A port and an HDMI 1.4 output, so existing USB-A devices and an HDMI cable will connect directly.

Will my older USB 2.0 flash drives and external hard drives work at full speed?

The single USB 2.0 Type-A port runs at native 2.0 speeds, while the two USB 3.2 Gen 1 Type-A ports will operate older drives at their own rated limits.
