Newegg offers the 3.7-lb. Lenovo Ideapad 510S Intel Skylake Core i7 2.5GHz 14" 1080p Laptop in Silver bundled with the Seagate 1TB Expansion Portable USB 3.0 External Hard Drive for $649.99 with free shipping. That's $20 below our mention of a similar model from last week (which didn't include the external HDD) and the lowest price we've seen for a 510S unit with this configuration. (It's also $61 under the best deal we could find for these items sold separately elsewhere, although most retailers charge over $700 for the laptop alone.)
It features an Intel Core i7-6500U 2.5GHz Skylake dual-core processor, 14" 1920x1080 (1080p) IPS LCD display, 8GB RAM, 256GB SSD, AMD Radeon R7 M460 2GB graphics, 802.11ac wireless, Bluetooth 4.0, 3-cell battery, and Windows 10 Home 64-bit. Deal ends May 21.
