All computers sold in the Resale.ee online store have been checked, cleaned and are 100% in working order, unless otherwise stated on the product listing. Batteries have been tested on all computers. All products have real photos — we have not used manufacturers' promotional photos but have photographed every product individually ourselves. All damage is visible in the photos.
We perform battery tests as follows: a 4K video plays at 60% screen brightness until the battery is fully drained. The video is played from a streaming service, so the computer's Wi-Fi connection and browser are also running in the background, which should fairly accurately simulate the average use of an average computer user. With lower screen brightness or less resource-intensive activity, battery life may be longer. With more resource-intensive tasks, battery life may be shorter.
Kui aku kestvus on rohkem kui 30% erinev tootekaardil olevast infost, tooteinfost kirjeldatud testimisviisil, siis kliendil on 30 päeva jooksul alates ostust võimalus esitada pretensioon ja saata või tuua arvuti meie esindusse, kus tehakse uus akutest tooteinfos kirjeldatud moel, kui uus akutest ei vasta lubatud tundidele(lubatud erinevus kuni 30%), siis aku vahetatakse välja sellise aku vastu, mis mahub kirjeldatud kriteeriumitesse (seal hulgas lubatud erinevus 30%). Kui arvuti läbib akutesti eelnevalt kirjeldatud viisil, siis arvuti saatmisel pakiautomaadi või kulleriga lisandub transporditasu 10€, ise kohale tuues käsitlustasu puudub
