Hi,

Try with an external USB keyboard to see if the same happens, this way we can see if it is related to software or hardware. 

Let me know!

Hi, with other keyboard it's everything ok.

It is possible to damage the laptop keyboard?

Anyone able to help?

I ended up just getting a refund and going elsewhere.

I had same issue Purchased in March delivered in April problem began almost instantly with 4 or 5 keys not working at all including the L key making it impossible to get onto the Dell website.

To be fair when I asked for a full refund it was immediately given the ok. My main point is WHY is a keyboard a problem for a laptop, laptops have been around for decades.
