So I recently updated my M18x r1 from 580m's to 780m's and it went flawlessly thanks to all the help i received. Well i sold my 2 580m's on ebay to an electronic parts company from what i can tell. They paid for the cards and installed them then contacted me and said that one of the cards was giving them an error and shutting off the system. Both cards were in full working order and handled with care after they were replaced. They are currently shipping the supposedly bad card back to me for a refund. with it being an electronic component that is sensitive to esd and user error i am hesitant to just say it is bad and hand them back their money when it is much more likely that if the card is bad they damaged it. I was hoping to gain an understanding of just what to look for as far as user error goes. i have before pictures of both sides of the board but i find it unlikely that it'll be sent to me with such an obvious user error. guys I am hoping my card boots right up but it'll be hard to say and I've got to disassemble my painstakingly reassembled laptop just to make sure it is bad. is it worth the trouble? am i better off eating the 250 refund and attempt to have it repaired or checked for problems? Thank you anyone for any advice and i hope i didn't post this in the wrong place.
