There could be manufacturing issues with any laptop that can cause you a problem. But Dell laptops have a unique yet bizarre problem in them. New Dell Latitude 6430u ultrabooks smell like a cat pee. Dell has done a thorough investigation. The company clears that this smell is not of cat urine. Dell also said that this smell not dangerous for health as this is not due to a biological contamination but a manufacturing process issue. Dell recommends affected users to send back their laptops for the replacement of parts.
The users complained about this issue first in June. One Dell user called Three West states on Dell support forum, "A few weeks ago I got new Latitude 6430u for work. The machine is great, but it smells as if it was assembled near a tomcat's litter box. It is truly awful!"
According to BBC, another user, Hoteca said, "I thought for sure one of my cats sprayed it, but there was something faulty with it so I had it replaced. The next one had the same exact issue. It's embarrassing taking it to clients because it smells so bad." But many of the Dell high end business laptop users thought that their cats are responsible for this smell.
Dell first states that this issue is raised due to the manufacturing process fault which has now been corrected. Dell support technicians first suggested cleaning the laptop air vents with compressed air to remove bad smell. But this did not help.
This issue gained hype when this discussion was moved on Reddit. Then another user named Malioz said that this smell could be of the laptop's polymer plastic. He questioned "whether chemicals causing the smell could be a health hazard."
Dell investigates the whole issue. Dell support technician SteveB said, "The smell is not related to cat urine or any other type of biological contaminant, nor is it a health hazard." Dell also states that this issue is resolved and new E6430u laptops do not have this smell now. Dell will also replace the parts of affected laptops.
