I have been working laptop mostly cause I like working on them,did anyone else find out that it is almost impossible to validate vista oem and I mean and I mean legit install when you have to reinstall on a new hdd,it always says that it is not valid and tells you to buy another windows,some of these laptop are about 3 years oldand they work fine once you do a good repair job,maybe they want us to do the unthinkable and "'fix them up"" so they work?i don`t like doing this but Microsoft are acting like pirates themselves so I don`t see poor people paying for something they already paid for,they don`t do it with win7 only takes about 10 minutes and it is validated.how do you guys cope with this? any way out? I would like to hear from you techs that work on laptop,
