Pros: I've been using the 840 for a year now and absolutely love it. Our business is switching over exclusively to these to replace our aging fleets of xx40, xx60 and xx70 series of Elitebooks. Users of the older models complained of the weight and bulk and love the new lightweight and slim desgin of the 840. Those that used the 12" model appreciate having a 14" screen that weighs much less than their 12" did. The backlit keyboard is a huge improvement over the LED light that used to be on the screen by the camera of previous models which didn't work most of the time. The speed and performance boost from the SSD is also a big improvement. A lot of our sales force is on the road and they can be a bit rough on PCs so not having a mechanical drive means much less support is needed because drives aren't crashing like they used to from being bumped, dropped, etc. We order all our 840s with 8GB RAM standard which is more than sufficient, but they can run up to 16GB which again for those with resource intense applications is a great option. There is also a USB port on the left side (lightning bolt) that you can use to charge your phone even when the PC is off which I find as a great benefit when needing to charge while on the go (such as walking through the airport or taking a bus/taxi someplace).
Cons: The only con for me is the 180GB SSD that comes standard. For most of our users it is more than sufficient, but some of the IT folks and power users could use a 250GB or 500GB SSD (I happen to run multiple VMs on mine for testing) so space is tight but it was easily fixed by installing a larger size SSD. Some people might find the lack of a CD/DVD as a con, but let's be serious. If you're still using CD/DVD media, you need to get with the times. USB sticks are cheap and hold a lot more data than a CD/DVD can and are much more portable. That combined with cloud and network based storage there is no reason to need a CD/DVD drive anymore. All media can be downloaded and installed directly. As a member of the IT team responsible for all client applications, I can't recall a time when we had any physical media to install software over the last 2-3 years unless it's a really old program that should be retired or upgraded to a current and supportable version anyway.
Overall Review: Had been a fan of the Lenovo line of notebooks for a long time but the newest Elitebooks have finally tipped me in favor of the HP notebooks. My brother got a new Lenovo notebook from his company recently and my HP 840 blows it away across the board: weight, size, features, performance...you name it.
Failed on power up
Pros: Great price, it's modular so I didn't have extra power cables i didn't need stuffed into my case.
Cons: Got everything connected and hit the power button and only the power supply and 1 case fan came on for about 3 seconds before it popped and tripped the breaker. Unplugged everything, and then tried applying power to just the power supply and it popped, sparked and smoked...DEAD.
Overall Review: Newegg support was fantastic. Issued an RMA for a refund with no hassles.
