The fan noise on this laptop is so bad that when you first hear it you're going to think your next door neighboor is using a leaf blower outside. I DARE you to tell me i'm wrong. I have an Acer aspire E15 and an acer aspire 5 (5504) and the fan noise combined from those two laptops are less than 1/8th the loudness of this new laptop. IT IS TERRIBLE. Think you can live with that? There's more: If you're a long time user of acer products you've become used to the 2nd function keys being assigned between the F3 to F9 keys and in blue. Thats GONE with this laptop. Here's the new configuration. F1 (previously f4) is the sleep function key, F2 (previously unassigned) is now airplane mode/wifi disable key, F3 and F4 (previously wifi and sleep respectively) are to adjust screen brightness, F8 (previously mute function key) has switched places with F9 now serving the keyboard backlight on/off function, F9 (previously keyboard backlighting function) is actually the mute function key. F10 and F11 (previously unassigned) are now the volume down and up function keys respectively. Just to add some additional frustration to the mix none of these keys are the second function anymore. So if you're used to hitting F5 to refresh browser windows or F3 to search now you'll need to hit the Fn Key first as the media functions take precedence in this new keyboard layout. This can actually be changed by rebooting and pressing F2 to enter the bios settings before windows loads. Even if you change the F1 - F12 keys back to their original hierarchic order the arrow keys are no longer the keys to access brightness or volume control but instead are music media keys. Good luck with that confusion. This new laptop basically is an all out attack on keyboard shortcut users even the Home key is now a point of frustration since they removed the dedicated home key and you're only left with the numlock access only home key that shares functionality with the number 7 key on the keypad. I also had to finish install necessary driver level software like the "acer quick access application" because as this was not installed there was no way to know if num lock or capslock was engaged as there is no LED indicating the status of these keys. Even if you Update the bios to the latest firmware version like I did it still won't solve the problem of the USB 3.0 ports having slower read/write speeds than a typical USB 2.0 port.Anyway At least THANK GOD on the plus side as a result of all that fan noise you do get ample cooling so the laptop does stay nice and cool..... HAHAHHAHAHAHAH PSYCH NOOOOOOOOOOOO no such luck my friend this laptop gets VERYYYYYY HOTTTTT in your lap and it is just pathetic that for all the fan noise you have to deal with it can't even keep the laptop at a comfortable temp while sitting there idle without a single thing going on. The charger is also not the regular acer charger so if you have other acer laptops that can share chargers interchangeably this one will not work with them.  BTW this is all within the first half hr of use. Imagine what I'll discover by this time tomorrow. Seriously guys and gals if you're a long time acer product user and you've become accustomed to any level of consistency across their products just forget it with this laptop. I currently use the A515-51G-5504 aspire 5 for productivity and while you may think that the only difference between the two is that one has a dedicated graphics card and the other does not TRUST ME those two laptops are like NIGHT AND DAY different when it comes to speed, noise levels, and general build quality. I cannot overemphasize how much you should AVOID buying this laptop. You are going to HATE IT!
