Hi guys , I just found a used laptop in a shop (Lenovo IdeaPad 3) it has (AMD Ryzen 7 5700U (Octo-Core 1.8 GHz / 4.3 GHz Turbo - 16 Threads - Cache 8 Mo)) , 512 SSD , 15’6 FHD ,they usually go for 720$ in my country Brand new on online shops , big shops charge even more , I found it for 550$ , the seller says it’s for that Price because there are some few hits in the back , I checked it and it had only few scratches at the top, also when I checked it , everything seemed to be working fine , all keyboard keys worked fine , but near the bottom , the keys kinda stuck and don’t click well, when I asked him he said it Can easily be fixed for free , I managed to convince him to upgrade it to 16gb ddr4 for the same Price , is it a good deal? And are there things I should be worried about while inspecting it? , im not a heavy gamer , I will usually use it for graphic design , coding , and music production , thanks all ❤️
