Heat and Noise
Sony has improved the cooling slightly in this refresh of the VAIO P. Sony maintained passive cooling for the VAIO P and we recorded temperature drops for most of the hotspots recorded during our test; but some of them were very slight. The netbook ran our 3D graphics and CPU benchmarking software for 20 minutes without stopping and here are the temperatures that were recorded (listed in degrees Fahrenheit):

Since it is still passively cooled and all of the models now feature a SATA SSD, there was hardly any noise whatsoever. In fact, in order to hear any noise during the test I had to put the bottom of the netbook up to my ears.

Battery Life
Our model comes with a 4-cell standard Li-ion 2500 mAh battery pack with 19Wh. It was tested in our labs on the “balanced” battery profile, 70% screen brightness, wireless on, and a webpage was set to refresh every 60 seconds. The Sony VAIO P second generation stayed on for 4 hours and 20 minutes, which is significantly higher than the 2 hours and 39 minutes that the 4-cell battery pack the original VAIO P was able to deliver in our test (keeping in mind that the testing method was slightly different last time). Lowering the screen brightness or turning wireless off will allow the battery to deliver even more life.

Battery life test results (higher scores mean better battery life):

Sony offers an extended life battery that has been tested in their own labs to last up to eight hours on maximum screen brightness and up to nine hours on “default power settings.”


While some would welcome the better processor speeds and cache, new touchpad, and display orientation; others would not think these options were worth sending their old VAIO P in or buying the refresh altogether. Whether or not this redesign is worth the higher price tag or not is up to individual taste and preference. This refresh has improved the processing speed and cache size but stuck with the Intel Atom, greatly improved the standard battery life, added a touchpad and an orientation and display switch option, improved the outer casing style, and more—all the while keeping the ultraportability of the prior version.


  • Extremely ultraportable (1.3 lbs, 8″)
  • Excellent keyboard and sturdy chassis 
  • Useful display-switch feature
  • Larger solid state drive


  • High price
  • Weak audio
  • Still uses an Intel Atom
  • Minimal upgradeability
