DO NOT USE STOCK THERMAL PASTE REALLY HORRIBLE. .. My CPU temps rose to a dangerous 72 C. I cleaned up the thermal paste and apply Noctua Thermal compound. Now when I game, my CPU does not rise above
No CDDVD ROM
There is a slot for you to buy and install an internal Drive but I'm having some trouble locating the correct Size of drive for this Notebook
SO MUCH Acer BloatWare. .. so much. .. Roughly 30 of Bloated Memory to delete. I'm going to wipe the HD and reinstall Wi 7, Wi 8 sucks in my opinion

If you are not a nitpicker then this laptop is fantastic. Now I am of the school that does not trash a product because of any minor shortcoming so perhaps the other people of my age will find a reason
Everything works (Linux Mint 17.3) out of the box, Wifi, network, chipset, buttons, ATI opensource and proprietary drivers, webcam, sound (sound quality is good), hibernate and sleep modes. Performanc
Difficult to access hard drive and ram
Some keys on the keyboard are smaller and require adjusting to
Bottom case is a bit tough to take apart for a hard drive or memory replacement
Display is not quite as good as you would expect. But the people who review it and say "snarf werst displer evur" are just babies
Battery life needs core speed stepping and ATI shutdown, can probably get 5 6W if pushed. Battery is pretty small for the size
