Questions about this item
How loud does the Inspiron 3520 get when the Core i7-1255U runs at 4.7 GHz all day?
The 10-core processor has a 1.2 GHz base clock and 4.7 GHz turbo; fan speed scales with load, so sustained heavy work will spin the fans higher than light tasks.
Which cables or peripherals must I already have to use the HDMI 1.4 and USB 3.2 Gen 1 Type-A ports on this laptop?
You need an HDMI 1.4 cable for external displays and standard USB-A cables or devices for the two USB 3.2 Gen 1 ports and the single USB 2.0 port.
Can I keep using my older USB 2.0 flash drives and SD cards with the Inspiron 3520?
Yes, the laptop includes one USB 2.0 Type-A port and a multi-format SD card reader that both work with legacy drives and cards.
