Question: Does it have USB 3.0 ports?
Document: This laptop is really great. The only things I would like improved are:1. To have USB ports on both sides. It has 3 USB ports and they are all located on the left of the keyboard.2. I wish the left click part of the mouse were a little longer than the right click side. I often hit the right when I intend on hitting the left click.3. It would be nice if the numlock key and the capslock key would light up when activated.4.
I found that the headphones and microphone input should not be shared. When using multiply USB devices the ports are sometimes too close
This is a bigger problem when using the laptop on something like a bed than it is if the laptop is on a hard surface. Turning the volume up a few notches can help solve the problem, but it is a little frustruating at first.The second thing I an unhappy with is the location of the USB drives. All 3 USB drives are directly next to each other on the left side of the laptop.
It would be great if i could just have it set up preeminently for headphones. (Or even better if there were 2 ports which just worked nice and simply as they should.). Is there a software solution for this?. I've had problems with the headphone jack on my previous Asus laptop (a Netbook bought 3 years ago), which often didn't, or only intermittently, recognise that headphones have been plugged in.It has suddenly turned itself off a few times, for no obvious reason.
I love this computer. It is good enough for my business as a photographer and thus need to do editing. I have no trouble running different editing software. It is also good enough to play online games. The only negative is that it is shy on ports and a space for a compact card which is larger than an SD card. ASUS is by far my favorite brand, I also have a PC in this brand and it is awesome as well.
ASUS X75A-DS51 17.3-Inch Laptop (Black)  Good laptop...Battery doesn't last as long as advertised. That's the only problem I have ran across.
We were a little concerned about Windows 8 but got over that really fast. The laptop is super. It's attractive and the 17.3&#34; screen is great. The set up was very quick and easy. Lots to learn yet but that will come with use. Very happy with the delivery and price.
My 3-star rating may reflect more my frustration with Windows 8 than the machine itself. I tried to link it to a friend's projector for my video presentation, but my ASUS wouldn't &#34;talk&#34; to his projector. So we had to disconnect mine and use his to laptop, so I could do my presentation. I may change my mind, but as of now, I loathe Windows 8 and am thinking about installing Windows 7.
I just bought an inexpensive wireless mouse so this should no longer be a problem.Both of these problems are small details and can be averted by simply using the laptop on a hard surface, turning up the volume a bit, or using a wireless mouse. The i5 processor and 5400 rpm hard drive help the laptop continue to run fast even when handling heavier loads while the 17.3 inch screen allows me to have multiple programs open on the screen at the same time.
I have owned multiple laptops and so far, this one is in my top 3 especially at this price range. I did a lot of research before purchasing and for what you get out of the box and compared to others is excellent. Nice bright display with good color depth. Performance wise it has a dual core, hyper threading Intel i5 with 8 GB of Ram. Compared to some other brands, you're going to pay a little more. The audio sounds goods, but I prefer headphones probably like most.
Answer: yeah, one.
