Servicing all here want to upgrade more RAM, want to swap the drive in case of defect or want to install an SSD. There is no service door, you have the whole remove cover, loosen screws 18 and then plastic hooks solve the unfortunately happen very quickly broken. Simple is certainly different. Unlike other notebook where one is ready in 2 min, one needs here sometimes 2 hours to change the SSD and then made half of the plastic clip broke. Video at YouTube helps unfortunately not, because there does not cancel all the clips oddly enough, with me but many, even though I had done carefully. Otherwise, the installation and operation of Windows7 64bit Easy is, after you have set in the BIOS Legacy.
