Hello there, Something about warranty, what I do know OEM-builders only give warranty for hardware problems. So if your HDD dies they will replace it for example. If you repartition your harddrive or if you delete the recovery partition and do a whole new install of windows they don't care. In the past I send some laptops back where I did a complete new install and repartition, after some time something went wrong with for example a memory module, those laptops came back with a new module and they didn't care about the harddrive that was comletely repartitioned. At least, you don't get warranty about software problems, only hardware problems.
