had a deal with him.. swap laptop + cash. Mine is dell latitude d820 + cash , his was asus f8sn. I thought ok na ung unit niya, in good condition no defects, kaso dami plang defects, mainly ang blue screen na halos 1month hindi ma solve ng ASUS support center(hindi ata marunong mag diagnose ang mga engr nila trial and error).. problem din ung webcam ng unit at ung battery hindi umaabot sa 100%.. Npka hassle ng unit na nabili ko di2.. Another thing, 1hr+ akong npahintay sa supposedly agreed time..
