Bluetooth 5.0 connects compatible accessories, and the full-size backlit keyboard includes a numeric keypad for productivity workflows.

Questions about this item

Does the G15 5520 include a Thunderbolt 4 cable and an SD card reader, or must I buy them separately?

The laptop has one Thunderbolt 4 port with DisplayPort alt mode and three USB 3.2 Gen1 Type-A ports; no Thunderbolt cable or SD card reader is included in the box.

Should I choose the 16 GB DDR5 configuration or look for a larger memory option for the i7-12700H?

This unit ships with 16 GB DDR5 and a 512 GB PCIe SSD; the 14-core i7-12700H handles modern titles well at this capacity, and both memory and storage can be upgraded later if needed.

What does the 120 Hz 250 nits screen mean for actual gaming on the RTX 3060 6 GB?

The 15.6 inch FHD panel refreshes at 120 Hz with 250 nits brightness, so the RTX 3060 can push high frame rates in competitive titles while the anti-glare coating keeps reflections low.
