 +====== Acer Travelmate P645-M ======
 +===== Author(s) =====
 +Scrandy (Tested Ubuntu 14.10)
 +===== Introduction =====
 +The Acer P645 is an excellent, very robust and very portable subnotebook with very good Linux compatibility. Except the 3G-modem, which I cannot test at the moment, the laptop seems to have nearly 100% compatibility. Powersaving can be tuned quite well with tlp and powertop. Most things work out of the box with Kubuntu 14.10.
  
 +If you want to buy one: watch out for minimal version differences within the same model number (IPS, HDD, CPU)!
 +
 +It would be nice, if someone could post, how 3G can be made to work.

 +|Fingerprint Reader|Not Tested| |
 +|Suspend/​Resume|works| |
 +===== Notes =====
 +UEFI Dualboot needs some work (especially if you are new to UEFI). I made a fresh WIn8.1 installation on the mSata SSD and then installed Ubuntu 14.10 also on the SSD (Both in UEFI Mode). Afterwards I replaced the Windows Boot Manager in the UEFI Setup with Grub2 and it worked.
 +
 +The high 156 DPI with Full HD needs extensive adaptation of the apps. There are several guides available but some Apps (Chrome etc.) still need fixing. I went with KDE and worked on firefox/​thinderbird with the about:​config fix. This worked when I uninstalled the oxygen icons for gtk. Some apps still are a bit small, but all relevant ones work well. If you do not like working on this, I suggest not to choose the HD-version. But this is a general problem and will improve over time, especially because of the emerging retina displays. ​
 +
 +All Chips (3G, NFC, Wifi, Keyboard-Light,​ HDD) can be switched off using tlp and self-congigured hotkeys getting power consumption down to 5.8 W (with 40% display light on) from above 10 W. So the battery saving can be tuned quite well and this laptop is ready for ultramobile linux usage.
 +===== Summary =====
 +The Acer P645-M works really well out of the box with Kubuntu 14.10. I will expand this article, when I have the time to test the rest. (Version tested: NX.V8VEG.025 on Ubuntu 14.10 in Winter 2014)

 +**If you got 3G working please post in the notes section how.**
