The Clevo W840SU is a low-voltage ultrabook, which allows to easily change hardware components (components are not - as usual for ultrabooks as well as macbooks - soldered onto the motherboard). It is reselled under various names, including Schenker S403, Tuxedo Book UC1402 and Nexoc B401. BT - not included WIFI - not included LAN: Realtek RTL8111 - working, needs kext by Mieze USB 3.0 - working, may cause crashes without DSDT patch on AppleXHCI Sound: Realtek ALC282 - working, needs DSDT and AppleHDA patches QE/CI - working, needs DSDT and SSDT patches VGA - not included HDMI - untested Trackpad: Elantech v3 - working with kext by EMlyDinEsH Sleep - working, super fast with apsd disabled Battery - percent working with kext by RehabMan, The battery does not report any discharge information, causes OS X to complain about the battery to be empty, even if it will still last for hours. Easy DSDT work-around is to set a static discharge rate in case battery does not report any. Camera - working, needs to be enabled using Fn-F10 first. SD card reader: Realtek - not working PCI device listing: lspci-nnvv-nowifi.txt IOReg: ioreg.txt Patched DSDT: DSDT-SSDT.zip - Replace SSDT with table id "SaSsdt " to have QE/CI, DSDT contains patch for BCM4322x Wireless devices --- I use OS X Mavericks. After adding my Dell Wireless 1550 Wifi card, i have problems with standby: The notebook wakes up immediately. Since I got bluetooth up and running (using BTFirmwareUploader), wake up is deferred by about 30sec. From the syslog I still suspect bluetooth to cause the problem (wake reason is EHC1 XHC, with no usb device plugged in). I did not have this problem with my Dell laptop running OS X - maybe I'm missing a DSDT method? As I don't need bluetooth, I'd even like solutions, that break Bluetooth in favour of sleep mode. Thanks in advance.
