Lenovo Googlebook leak reveals the name of Google’s new laptop operating system

With Google’s New York media event happening next week, the early leaks continue to roll in. Just yesterday, we saw how Bluetooth SIG filings confirmed the commercial branding for Lenovo’s upcoming 15.3-inch flagship, the Lenovo Googlebook i (15″, 12).

Now, a fresh report from The Mac Observer claims to have obtained high-resolution product renders alongside Lenovo’s official product spec sheet for the device. For anyone who has been around here over the past month, much of the hardware listed in this latest leak isn’t brand-new territory; it simply provides concrete, manufacturer-level backing for the press renders (I’ve included below) we discussed back in August.

However, hidden directly inside Lenovo’s documentation is one massive detail we’ve all been waiting on: the actual commercial name of the operating system.

Is it officially called “Googlebook OS”?

Ever since Google first pulled back the curtain on its desktop ambitions back in May, the software branding has been a bit of a mystery. We know the platform is built on an Android foundation, and internal activity has continually used the codename “Aluminium OS”. But when it comes to what Google will actually call the software on the retail box, we’ve all been left guessing.

According to Lenovo’s product sheet that Mac Observer obtained, the operating system powering the Lenovo Googlebook 15 is simply listed as Googlebook OS.

If this documentation reflects final retail marketing assets, that naming makes total sense. Google has never shied away from straightforward platform branding: ChromeOS runs on Chromebooks, Wear OS runs on smartwatches, and Google TV powers streaming dongles. Calling it “Googlebook OS” instantly communicates the platform identity to everyday consumers without confusing them with mobile Android terminology.

Of course, until Google officially utters the name on stage in New York, we have to take any pre-launch product sheet with a grain of salt. But having Lenovo print “Googlebook OS” on their official spec sheet gives us the strongest hint yet about what we’ll be calling this software moving forward.

Everything else confirmed on the Lenovo Googlebook i (15″, 12)

Beyond the software label, the leak doubles down on the premium hardware package we’ve been tracking for the past few weeks, including:

• 15.3-inch 120Hz OLED Display: Lenovo is equipping the machine with a 2.8K (2880 x 1800) OLED touchscreen boasting a 120Hz refresh rate, 500 nits of peak brightness, and 100% DCI-P3 color coverage.
• Intel Panther Lake Silicon: As the lowercase “i” in the Bluetooth certification confirmed yesterday, this is an Intel machine. The document explicitly lists the Intel Core Ultra 5 325 processor paired with Intel Graphics.
• Memory & Storage: Buyers will see configurations featuring 16GB or 32GB of LPDDR5x RAM alongside 256GB or 512GB of onboard storage.
• Weight & Battery: Despite packing a sizable 15.3-inch panel, the aluminum chassis weighs in at just 2.84 pounds (1.29kg) with a 70Wh battery rated for up to 11 hours of runtime.
• Port Selection: Dual Thunderbolt 4 ports, a full-sized USB-A port, HDMI 2.0, and a 3.5mm headphone jack.

With HP’s Snapdragon X Elite Googlebook 14c clearing Energy Star and Lenovo’s 15-inch Intel flagship fully laid bare, we’re continually inching closer to knowing all there is to know before the media preview on September 15th. There are still other devices out there that we don’t have all the details on, so stay tuned. I’d expect more to leak out in the coming days for sure!
