Accidentally leaked user manuals from PC maker Lenovo show that the company is preparing a new laptop that runs Android instead of Windows.

Called the IdeaPad A10, the laptop has a 10.1 inch HD screen and is listed as an Android device, according to the manuals uploaded on Lenovo's site.

The laptop's 10-inch display also functions as a touchscreen. It can be opened up to 300 degrees, supporting the screen for reading or touching while the keyboard rests face down. In addition, the keyboard has signature Android buttons for "home screen", "previous" and "apps screen", found on the bottom of many phones and tablets running the Google OS.

Lenovo had planned on making an official announcement for the device, said Chris Millward, a spokesman for the company, on Thursday. But somehow, Lenovo unintentionally leaked the user manuals online, he added.

"The product has not been canceled. It will be going out to the market," he said. Lenovo will later announce launch dates and pricing information.

The laptop's specs show that it could be a budget product. It has an Arm quad-core 1.6GHz processor from Chinese firm Rockchip, 1GB or 2GB of RAM, and 16GB or 32GB of storage. There is also a 0.3 megapixel camera, a microSD card slot and an HDMI port.

Tech vendors are increasingly experimenting with Android at a time when demand for traditional Windows PCs has been waning. Earlier this year, Acer and Hewlett-Packard showed all-in-one desktops using the Google operating system. HP's product, called the Slate 21, has a price of $399.

On the convertible PC side, Asus has shown a hybrid device that can run both Windows and Android. Called the Transformer Book Trio, the product operates as a stand-alone Android tablet, but when attached to its keyboard it can also boot up Windows.
