1st one i got, Windows didn't even load, called for Support, got transferred to the manufacturer, Lenovo, who said product was out of warranty, take it to a store and have it repaired. A certified refurbished laptop, day 1 out the box, never used, never got it to turn on, I have to pay to get repaired? After a terse argument with the rep, I was sent another one.This one I currently have, the fan is always vibrating loudly, always, the DVD drive randomly pops open as does the memory card slot, the Esc to all the Function Keys are all raised meaning I can literally see inside the keyboard from outside so i have to be mindful where dust etc is concerned. The left click sometimes I have to click three times for it to accept. I used 2 wireless mice and 1 wired as well as checked the drivers to ensure they were up to date. Issue still persist, solution? Clean install perhaps, another headache.Easily my worst Amazon experience to date and I love Amazon
