Needed this laptop to work remotely from home.  Wow!  Love it!  The speed, the ease of the keyboard, separate number section on the keyboard (I do a lot of numerical data entry) - not a scratch, mark, discoloration - nothing.  Bought as renewed and really love it!  Battery lasts for at least 8 hours - I usually use plugged in so its not a problem for me.Once I figured out the remote program - it works beautifully!  Thanks Amazon for a perfect product (yes I only had for 3 days & used).  Will definitely update this review if I come across any glitches - most are operator error!Thanks again, Amazon!
