Never buy DELL laptops
Not sure if other tech specialists experience this,
But the laptop keyboards are seriously made with very poor materials.
Other laptop brand makes are better in that aspect.
To summarize things up, we have about hundreds of laptops bought from DELL and almost 20% of them ends up with this condition.
At first I thought perhaps this could be due to wear and tear but one of the laptops returned in this condition is of only 2 months of usage.
Raising this up to DELL is another fuming issue as well, because the only thing that the customer service supports do is to inform you that this is a chargeable service and keyboard replacements are not covered by warranty (WHAT?!?!)
tldr ; save your money, don't buy dell notebooks because their CEO is a money loving grub that exploits their keyboard make and charges their customers to replace their shitty keyboard
*model makes are Latitude 5000 series
