====== Lenovo Thinkpad L440 ======

===== Hardware Overview =====

  * CPU (Platform): Intel Core i5-4300M CPU 2.60GHz (Haswell)
  * Screen: non-glare (matte) 14.0" HD (1366x768) or 14.0" HD+ (1600x900)
  * Memory: 4GB (up to 16GB)
  * Sound: supported by ''%%snd_hda(4)%%'', works
  * Ethernet: Intel I217-V (supported by ''%%em(4)%%'')
  * [[/WiFi|WiFi]]/Bluetooth: some Realtek chip (only Bluetooth works)
  * Card reader: not supported :(

===== Notes =====

%%FreeBSD%% support of this laptop is very limited.  Sound and Ethernet are recognized by fresh 11-CURRENT (as of [[http://svnweb.freebsd.org/base?view=revision&revision=271243|r271243]]), Bluetooth seems to work (albeit first few times I tried ''%%service bluetooth start ubt0%%'' it did not succeed for some reason), but not [[/WiFi|WiFi]] or card reader.

Does not come back from suspend properly (screen stays dark), tested only on the console (not X11).  From a working system, pressing the power button or doing ''%%shutdown -p now%%'' behaves as expected.

Official specs claim battery life of 12+ hours, but unplugging the AC adapter and running ''%%acpiconf -i0%%'' shortly after estimated just 2:50 of remaining time (''%%powerd(8)%%'' was not running though).
