All the built-in reports can be found in the Report center. Here is the direct link to the report you are missing: https://www.lansweeper.com/forum/yaf_postst15174_Windows--Laptops-and-desktops-list--Built-in.aspx#post51424
Additionally, if you want to filter for laptops only, I recommend using the tblPortableBattery.AssetID field. This will only have a value for Laptops. You can then also add a criteria to tblAssetCustom.Manufacturer to filter for a specific manufacturer.
