Computer giant Dell has made a rather embarrassing admission — that some units its ultrabooks smell like cat urine. However, the company says that the smell is “not in any way related to biological contamination” or a health hazard.

The company made the admission came after a number Dell users complained that their Latitude 6430u Ultrabooks “smell of cat urine”.

A user by the name Three West on Dell Community was to the first to complain that hisnew Latitude 6430u ultrabook emanated smell of cat urine. He posted: “The machine is great, but it smells as if it was assembled near a tomcats litter box. It is truly awful! It seems to be coming from the keyboard.”

His concern was echoed by several other buyers of the same model, who complained that the smell was coming from the keyboard. They said that the smell remained even after the keyboard, palm-rest, motherboard and other components had been replaced. Some users even had their ultrabook replaced, but the unpleasant smell was present in the new models as well.
