IdeaPad S series
The IdeaPad S Series is a series of notebook computers launched by Lenovo in October 2008. The IdeaPad S10 was initially scheduled for launch in September, but its release was delayed in the United States until October.

The S series began with the IdeaPad S10, the lowest cost model, powered by an Intel Atom processor in a 10.2-inch subnotebook. Later, more expensive laptops in the S-series also powered by Intel Atoms were released. Once the Atom CPU line was discontinued, the main line of lightweight S series laptops switched to alternatives, such as the low-power AMD A-series, Intel Celeron, Pentium, and low-cost versions of Y-series CPUs.

2008
The IdeaPad S10, the first laptop in the IdeaPad S Series of netbooks, was released in 2008.

S10 
The IdeaPad S10 was Lenovo's first netbook. While Engadget found the design unremarkable, the low starting price was well-received. The S10 featured a  TFT active matrix 1024×576 or 1024×600 display with an 80 or 160 GB hard disk drive and 512 MB or 1 GB DDR2 Random Access Memory, both of which could be upgraded via a trap door on the bottom of the netbook. The initial S10 featured 512 MB of RAM soldered to system board with an expansion SO-DIMM slot for further upgrades to 2 or 2.5 GB (2.5 GB was only usable with an operating system with support for sparse memory regions). The processor was an Intel Atom that ran at 1.6 GHz. The S10 supported IEEE 802.11 b/g wireless networking and had two USB ports, an ExpressCard expansion slot, a 4-in-1 media reader, and a VGA output. These computers received positive consumer reviews and a 9/10 rating from Wired magazine.

In May 2009 Lenovo introduced the S10-2. While the S10-2 shared many traits with the S10/S10e, it omitted the ExpressCard34 slot, featured a new physical design, added an additional USB port, and enlarged the keyboard, touchpad, and sizes of the hard drive and SSD.

2009
The IdeaPad S Series netbooks released by Lenovo in 2009 were the S10e, S10-2, and the S12.

S10e
The IdeaPad S10e was a re-launch of the IdeaPad S10, with features updated for the education market. The netbook included a quick start operating system and 5 hours of battery life at a low starting price. It weighed 2.8 lbs, with a form factor of 9.8 x 7.7 x 0.9–1.4-inches. The netbook offered a wide keyboard occupying almost the entire width of the chassis, and LAPTOP Magazine reported that it was easy for even adults to type on.

S10-2
The IdeaPad S10-2 was a 10-inch netbook with a 1.6 GHz Intel Atom processor, 1GB RAM, a 6-cell battery, and Intel GMA Integrated Graphics. Notebook Review reported that the netbook's design offered "a cleaner and smoother appearance all around". The specifications of the netbook are as follows:

S10-3
The IdeaPad S10-3 netbook was praised for its full-size keyboard, design, light chassis, and low price. It was criticized for its navigation experience, touchpad, low capacity hard drive, and the lack of options for customization. Michael Prospero from LAPTOP Magazine indicated in his review that Lenovo had addressed some of the issues raised about the S10-2 netbook and praised the keyboard and the design. He also indicated that the storage capacity was not on par with competitor offerings and that the touchpad could have been improved.

S10-3t
The IdeaPad S10-3t was a netbook that was also a convertible tablet. The S10-3t netbook was among the first computers to use the 1.83 GHz Intel Atom N470 processor. The software BumpTop was preloaded and offered a desk-like view of the desktop in 3D for ease of use.
