Almost 2 years ago I decided to roll the dice on a refurb from www.woot.com. It was a Lenovo M90P I5 8GB memory 500 GB hard drive. It arrived without the optical drive it was supposed to have-a bad keyboard and a visibly damaged POWER button. On the first use I thought it was virus-infected...but that proved to be wrong. I later figured out that it was maxxing out my DSL connection while doing a Win 10 Pro update. Since then it has been okay with one exception. Sometimes I use it to stream video from ESPN and FOX SPORTS. I've experienced crashes with it that I think/guess may be due to the onboard Intel video being overwhelmed. I only spent $200 on it, so I'm not sure it's worth bothering to fix it. It's al least 8 years old if not more. Next time, I probably will use someone else and not Woot.
