Lol,Worked great until 5490 laptop did a total system crash within the first 12 hours.If you're able to get a non-defective 5490, these are great laptops and the keyboard is as awesome.To this vendor:If you refurbish, then run it to death to make the software and hardware are stable.But ***** stars for Amazon's computer tech support.Final resolution after A's Tech support (and advice) took the full refund and shipping the 5490 back.
