Dell has the best warranty support in Malaysia, upgrade to 3 years on site for RM300, best peace of mind for students

(anything go wrong with hardware, give Dell a call, technician will go to your place to fix it next business day)
agree... when your dell falls apart (trust me it will), at least they will come repair it for you, no need you to take back to service center fix and wait and blah blah blah, same day can settle, but you must "smart" enough to do the pre diagnosis and tell them which part is fails, then they will bring the part to you and repair straight away, be it hard disk, screen, motherboard, keyboard, touchpad etc...
