+ | ====== 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. | ||

+ | |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) | ||
