is there mercury in dell computers ?

i have a dell laptop computer which i work on from home constantly, so i’m on it most of the day

Depends on how old it is. Mercury is usually found in the screens of both desktops and laptops. But only minute amounts and they are contained in a way that is harmless unless your laptop is damaged in a unusal way that could leak it out. But, keep in mind it’s a very small amount of mercury and it isn’t in liquid form and within the material of the screen and silicon.

You must be getting mercury from a different source. Where do you live? Where are you getting your water from? Have you been eating lots of fish? trace your steps.
