+= Overview =
+
+Most of the features seem to be working with Linux >= 3.9
+
+== Hardware ==
+
+* CPU Intel(R) Core(TM) i5-3317U CPU @ 1.70GHz
+* RAM 4 GB
+* HDD 128GB SSD

+= Configuration =
+
+Full configurations is in my
+[https://raw.github.com/grwlf/nixpkgs/local/machines/samsung-np900x3c-v2.nix nixpkgs branch]. Note, it requires several local packages.
+
+=== Touchpad ===
+
+Touchpad is detected as 'ETPS/2 Elantech Touchpad'. xf86-input-synaptics handles
+it well. Corresponding config lines:
+
+<pre>
+  services.xserver = {
+    synaptics = {
+      enable = true;
+      accelFactor = "0.05";
+      maxSpeed = "10";
+      twoFingerScroll = true;
+      additionalOptions =
+        ''
+        MatchProduct "ETPS"
+        Option "FingerLow"                 "3"
+        Option "FingerHigh"                "5"
+        Option "FingerPress"               "30"
+        Option "MaxTapTime"                "100"
+        Option "MaxDoubleTapTime"          "150"
+        Option "FastTaps"                  "1"
+        Option "VertTwoFingerScroll"       "1"
+        Option "HorizTwoFingerScroll"      "1"
+        Option "TrackstickSpeed"           "0"
+        Option "LTCornerButton"            "3"
+        Option "LBCornerButton"            "2"
+        Option "CoastingFriction"          "20"
+        '';
+      };
+  };
+</pre>
+
+=== Wireless ===
+
+System requires iwlwifi-6000g2b-6.ucode in order to work. I've extracted the
+file from some debian package and placed it into /root/firmware. Corresponding
+config settings:
+
+<pre>
+  hardware.firmware = [ "/root/firmware" ];
+</pre>
+
+= Problems =
+There are some. See

+
+=== BIOS problems ===
+I had to disable SSD boot completely in order to boot from USB. Just changing boot priority didn't help.
+
+Fix: Update BIOS up to recent version
+
+=== Battery ===
+Battery charging/discharging indicator doesn't work good.
+
+Fix: Update BIOS up to recent version
+
+=== Lid ===
+Acpi thinks lid is always open
+<pre>
+[ierton@greyblade:~]$ cat /proc/acpi/button/lid/LID0/state 
+state:      open
+</pre>
+
+Related [https://bugzilla.kernel.org/show_bug.cgi?id=44161 Kernel bug #44161]
+
+=== Multimedia keys ===
+* rfkill/fanless don't work
+* volume up/down don't work
+* brightness up/down work, but release is broken
+* touchpad disable works
