Lenovo has posted an order page for the IdeaPad S10 mini-notebook. For $429 you can get a laptop with a 10.2 inch display, 512MB of RAM, an 80GB HDD, a 3 cell battery, and a 1.6GHz Intel Atom CPU. And as one Engadget reader points out, you can apparently knock 15% off the price with the coupon code USPIDEAPAD15.

But the checkout process doesn’t seem to work just yet. While you can add a computer to your cart, add a few customization options, and proceed to checkout, when it comes time to process your payment, an error message pops up telling you to try again later.

While you can add software and hardware (like a wireless router) to your order, there does not seem to be an option to upgrade the RAM, get a 6 cell battery, or change the hard drive to an SSD. Perhaps these options will be available later. Oh, and if you want a red or white unit, you’ll have to pay an extra $10. The $429 price only applies to the black model.

The laptops also won’t actually ship until October September 9, so it probably doesn’t matter too much if you get your order in this week or next.

Update: It looks like orders are going through now. Just placed mine!
