NEC LaVie Notebook PC LL750 F [Manufacturer] NEC [Series] LaVie [OS] Windows 7 Home Premium (64bit) [CPU] Intel Core i7-2670QM (2.20GHz) [Memory] 8GB [Storage] HDD Approximately 650GB [Optical Drive] DVD / BD Playback Possible [Screen Size] 15-inch class [Speakers] YAMAHA [Included Items] AC Adapter [Condition] Initialized / Operation Confirmed AC adapter included. Mouse is also included, but it has discoloration and deterioration due to sun exposure. Battery life is estimated to be around 1 hour. (See image 3) I have taken good care of it, but the OS is old, and its uses are limited for a novice, so I am selling it. There seem to be no operational problems, but please understand that it has been stored by a non-professional and is an old model before purchasing.
