Put a MacBook pro in to cex to sell it as I hardly ever use it. They said they needed an hour to test it so left it with them. Came back to them telling me it hadn't passed the test as the battery power had dropped below 20% in an hour. This surprised me as I had never really used it but had kept it charged up as I charge a couple of torches through it. Went home and thought I must test it myself. So ran it for an hour with the TV on and it only dropped 8% over the hour . And when I actually looked at it in the daylight I could see they had scratched the cover in four places,they hadn't bothered to put the power cable in the tray under the computer and left it on the lid .
