Groupon offers the refurbished 4.9-lb. HP EliteBook 8440p Intel Core i5 2.4GHz 14" LED-Backlit Laptop for $279.99 with free shipping. That's $5 under our mention of a refurb from last month and the lowest total price we've ever seen for a HP EliteBook Core i5 model. (It's a very strong price for a laptop with a Core i5 CPU in general, and a current low for a comparable refurb now by $29.) Features include an Intel Core i5-520M 2.4GHz dual-core processor, 14" 1366x768 LED-backlit LCD, 4GB RAM, 250GB hard drive, 802.11n wireless, Gigabit Ethernet, 6-cell battery, and Windows 7 Professional 64-bit.

A 90-day warranty applies, but it is unclear who backs it.

Update: As one of its daily deals, Woot has the same laptop for $249.99 plus $5 for shipping. Deal ends today.
