The notebook is equipped with two 512MB modules of DDR2-533 SDRAM which work in dual-channel mode. One module is installed on the mainboard and cannot be removed; the other is accessible to the user. You can replace the latter with a 1GB one to have the maximum amount of system memory supported by this notebook.

I measured the temperature of the hottest spots on the notebook’s surfaces with an infrared thermometer after it had worked for half an hour in the Classic test mode of Battery Eater Pro 2.60 (the ambient temperature remained constant at 23°C during this test) and got the following numbers:

  • LCD panel – 39°C
  • Keyboard – 38°C
  • Bottom panel – 38°C

The temperature is rather high. I also measured it to be 46°C at the exhaust hole on the notebook’s left side while the touchpad’s temperature was 34°C. These are not critical numbers, yet there’s nothing good about them, either. The small dimensions of the S6F made it hard for the engineers to develop an efficient cooling system even for a Low Voltage processor. But you can use it as a heating pad in winter. J

The table below lists the specification of the S6F in comparison with that of the ASUS W6F:

Test Methods

The notebook’s hard drive was formatted in NTFS before the tests. Then I installed Microsoft Windows XP Professional SP2 with DirectX 9.0c, system drivers (from the included disc), and Windows Media Encoder 9.0 with Windows Media Player 9.0.

The following settings were used for the tests:

  • Power-saving services – Off
  • Audio subsystem – Off
  • Network services – Off
  • Maximum screen brightness
  • Maximum resolution of the display selected (1366x768)
  • Windows Taskbar is Unlocked
  • Windows Taskbar hides automatically
  • Classic Desktop theme
  • No background image on the Desktop
  • No screensaver
  • Low security level
  • Pop-ups blocking disabled

Two power modes were used. First, I selected the Always On power mode for the maximum performance and the shortest battery life. Then I switched to the Max Battery mode for the maximum battery run-down time.

Our tests:

  1. Performance benchmarks: synthetic (SiSoftware Sandra 2005, PCMark 2004), office and multimedia (Business Winstone 2004, Multimedia Content Creation Winstone 2004), and games (3DMark 2001 SE Pro, 3DMark 2003 3.60, Quake 3, Unreal Tournament 2003)
  2. Battery life tests (Battery Eater Pro 2.60)

There are three test modes in Battery Eater:

  • Classic – the system bears the highest and evenly distributed load
  • Reader’s test (the pages are browsed through each 15 seconds)
  • Idle mode

I used the first two modes as they are in Battery Eater, but in the Idle mode (when the test utility doesn’t put any load of its own on the notebook) I played a movie from a CD-R disc. The notebook’s optical drive refused to read DVDs – I hope it is a defect of our particular sample of the notebook, so I don’t count this in among its drawbacks.
