I have bought this laptop in 2018 and till now laptop is facing soo many problems. keyboard have been changed 4 times after soo many mails and tweet and ignorance is there top priority. i was facing screen issue from start. But i ignored it but suddenly from one small black dot it kept increasing to 2 now there are white dots too, total nine dots. i asked acer first they said they don't cover this in warranty(pricey screen). again i tweeted acer soo many times then they replied and asked me to email them and they asked again for picture i have provided them then they logged the complain (case id 3271295I)and service engineer came and he can see the dots properly and acer need picture of dots in bios. should i use laptop in bios mode or play move in bios. service engineer requested acer for parts but acer clearly denied it and said it is a dead pixel but dead pixel(dead pixel doesn't change color from angle) and it is not covered under warranty and you should go to nearby service center and pay the charge to get the screen replaced. and they closed the case saying "DP-09-DISPLAY UNIFORMITY". many company chnage the screen witout hassel like MSI, HP, LENOVO but not ACER.i begged them to replace the screen and i am student and i can't pay for it even i have extended warranty then what's the use of warranty when a consumer have to pay for all important component mostly pricey one. now they are again ignoring me no email replies no tweets replies. worst after sale service i woul never suggest anyone to buy ACER laptops or any product.
