SmartCard Reader

  • It seems that the integrated smartcard reader does not work under linux (see HP Support document, Ricoh Smart Card Reader Stops Functioning After Installing Linux).

Power consumption

  • On Linux, get instant battery power consumption with (unplug power cord first!):
watch grep rate /proc/acpi/battery/BAT*/state
  • Maverick
    • Luminosity set to lightest
    • Text console (X at login console, no X activity)
    • Wireless off
    • Lowest we get on idle is 947mA on BAT1.
  • Precise
    • Stock install, default driver: 1898mA on BAT1.
    • Stock install, default driver, min. luminosity: 1631mA on BAT1.
