So i purchased a laptop(Lenovo)from Amazon last month(12th October)n it has some issues. I updated the Bios last night n when I woke up n checked this morning , i found out that the screen is pitch black(no display) although it’s turning on n the backlit keyboard are working (can’t press the caps,num n esc button tho…like not blinking) So since , i bought it online I’m clueless on how to claim my warranty(i have softcopy)… I asked one of my friend n he told he told me to just go to any Lenovo service centre n i can claim it … does it work tat way ?
