HP Envy 14 and Envy 17 finally revealed

Well, they’re finally official now and I can quit receiving these kazillion emails about the upcoming Envy 14/17 models… wait, at least until the Envy 11 and Envy 18 emails start flooding in a couple months’ time HP Envy 14 and Envy 17 finally revealed . Right now, the information being provided by HP is scarce. But after some “digging around”, I’ve managed to compile a much more comprehensive list of specifications for the Envy 14 and Envy 17, more than you’ll find on other sites out there. All the info I’ve listed below are accurate/confirmed except where noted otherwise.

For both the Envy 14 and Envy 17, the following things will come as standard/available features:

  • Choice of Intel Core i5 dual core, Intel Core i7 dual core and Intel Core i7 Quad core processors (yes, the Envy 14 can be configured as a quad-core machine!)
  • Fully backlit, chiclet style keyboard; NO annoying ‘quick media/quick launch’ buttons to hinder typing
  • Metal/aluminum chassis with metal etching design (same patterns on the lid/palmrest as Envy 15)
  • HP True Vision “HD” webcam (I think they can record/webconference in 720p; haven’t confirmed, I’m not really a big webcam user)
  • Built-in slot-loading optical drives (contrary to earlier documents and HP info; somehow someone managed to squeeze in those optical drives)
  • 7200 rpm hard disks will come standard; solid state drives (SSD) will also come as an option
  • Dual built-in microphones
  • Extra large button-less trackpads with brand new trackpad firmware/software for improved operation (really)
  • Much improved cooling/airflow and heat dissipation
  • LAN port for you network cable users
  • Dedicated audio in and audio out ports for microphone and headphones respectively (unlike the single combo port on the Envy 15)

And looking at them individually now, first we have the HP Envy 14:

  • 2 dedicated USB ports + 1 combo eSATA/USB port
  • Standard full-size keyboard without numeric pad (doh!)
  • 14 inch 16:9 aspect ratio “HD” (at least 1366 x 768; higher resolution panel options unconfirmed) LED backlit display; this one’s an “extra-bright” HP Radiance display (similar to how the Envy 13 had a 13 inch Radiance display)
  • Two speaker Beats-branded (or logo stamped) speakers
  • Single hard disk bay
  • 2 or 4 DDR3 RAM slots
  • 1 GB (confirmed) of ATI Mobility Radeon 56xx or 57xx graphics(unconfirmed; dm4 has ATI 5400 series graphics so the Envy 14 should have something higher)
  • Optional (or probably standard in some countries) slim battery slice (styled ala Envy 13/Envy 15 battery slices) brings battery life to “up to 13.75 hours”
  • Mini Display Port and HDMI port (No VGA out)
  • Thin design, around an inch thick

The HP Envy 17

Next up is the much-discussed Envy 17:

  • 3 dedicated USB ports + 1 combo eSATA/USB port
  • Standard full-size keyboard WITH numeric pad
  • 17 inch 16:9 aspect ratio full HD (1920 x 1080) display; appears to be a non-Radiance display
  • Two speaker Beats-branded speakers plus “Triple Bass Reflex” (fancy name!) miniature subwoofer
  • Dual hard disk bays (HP says you can have up to 2 TB of storage, not sure if they made a typo there because 2 TB in a notebook sounds… wrong)
  • 2 or 4 DDR3 RAM slots
  • 1 GB ATI Mobility Radeon 5850 graphics with Eyefinity “enabled”
  • Optional extended primary battery juts out the bottom of the notebook
  • Whopping THREE display output ports: Mini Display Port, HDMI and VGA out
  • ATI Eyefinity support allows you to hook up three displays to the said three display output ports without any adapter needed
  • Thin design, around an inch thick

And finally, we have a bunch of question marks floating around which I’ll post answers to when I get more information:

  • Do the HP Envy 14 and Envy 17 support USB 3.0? If yes, how many of the ports are USB 3.0 and how many are USB 2.0?
  • Is dual monitor “Eyefinity” enabled/do-able using the Envy 14?
  • Seeing the Envy 17 has a  “stick out style” optional primary battery, will there be any (if at all) sort of slim battery slice for it?

I’m sure one of these days, either the Envy 14 or Envy 17 or both is gonna show up at my door, so meanwhile let’s discuss. You can start shooting me your questions so I can find answers to them the minute I get the chance to test out the new HP Envy’s.

Elitebook 8440 and 8540 have better heat dissipation than old generation

I just finished several hours of intensely working out HP’s new Elitebook 8440p, Elitebook 8440w and Elitebook 8540w models this week running several games in a row (special thanks to several friends who helped). Well, to be frank, we weren’t just ‘officially’ testing them – we had lots of fun playing the latest game titles and creating fancy CAD car models while at it!

I’m not gonna post a whole bunch of benchmark and temperature numbers here, perhaps at a later point in time, but today, I want to keep things simple and straightforward. The HP Elitebook 8440 and 8540 models have very much improved heat control compared to previous models. So far, I’m not sure what’s bringing such a huge improvement – better fan speed control, reshuffled component layout or more efficient components – but there was a tangible difference I could feel. After about 8 hours of running a mix of AutoCAD, 3Ds Max, Left4Dead 2 and Need for Speed Shift, I could literally hold the quad core Elitebook 8440w and 8540w models using my bare hands, by the bottom of the notebook, without getting my fingers and hands fried. The dual-core Core i5 running Elitebook 8440p fared much better: after going through the same stress test, it really didn’t feel as if the notebook had been doing any work at all – it was as cool as a notebook that had merely been idling with some windows open.

For comparison’s sake, I wouldn’t touch the bottom of any old generation Elitebook that I knew had just undergone some heavy task lifting because they can literally burn!

Off topic: Anyone know why notebooks can suddenly ‘switch off’ and how to solve this problem? There was an Elitebook 8730w (among other various notebooks) at the gathering which frequently (and suddenly) switch off without warning. I suspect it’s due to overheating (processor can go up to 90-100 degrees Celcius running the same apps/games as above) though I’ve tried cleaning the fan and even removing the bottom panel for better airflow – but no luck.
