Questions about this item

What real-world speed can I expect from the Core i5-1135G7 quad-core processor?

The chip runs at a 2.40 GHz base clock and can boost a single core up to 4.20 GHz with 8 MB of L3 cache, so everyday tasks feel snappy while heavier loads stay within thermal limits.

What wireless standard does the laptop use and what does it limit?

It connects via 802.11ac Wi-Fi, so the practical ceiling is the router’s AC capabilities and local interference rather than any newer protocol.

Will the 15.6 inch chassis fit in a standard 15 inch laptop sleeve?

The three-side narrow bezel keeps the footprint close to a traditional 15 inch body, so most sleeves sized for 15.6 inch devices will accommodate it.
