A laptop with built in GPS? Cool. Brand/model?

Go into the tools section. Find add a GPS. Open CPN should be able to sense the GPS, Usually this is done through a comm port.

Re: Open CPN ??

Legacy programs under Windows 8 or 10 do not typically recognize the GNSS hardware that is built into laptops and tablets. In other words, the new tablet-style "apps" recognize its API, but old-style "programs" that look for a COM port or TCP port do not.

So you need a separate program running in the background that will bridge between the GNSS API and the old-style program, emulating a TCP stream that OpenCPN can see. There are commercial paid options available, but I have done perfectly fine using the free GeolocationTCP software by Petr Simon:

More info on these issues is best addressed on the CruisersForum section devoted to OpenCPN:

OpenCPN - Cruisers & Sailing Forums

FWIW, I use OpenCPN with NOAA's RNC and ENC charts as my primary chartplotter. I have two Miix2 8" touchscreen tablets running Window 8. One is a backup. These tablets have GPS built in, but equally importantly they have extremely bright daylight-readable screens (helped with a matte screen protector). It also helps that they are polarized in a way that allows me to wear polarized sunglasses with no loss of screen brightness. The tablets have been discontinued for a couple years, and I haven't seen anything that works quite as well. I've posted more info over on CF.
