Just had the same issue, with the exact same set of keys. No spillage, I barely had the laptop for a month.

I just sent in the laptop for repairs since it was still under warranty. Took about 2 weeks for "repairs" to complete.

Yet even after receiving it back, the same keys are starting to go bad again. I'm starting to think it's just this model of the 7000 series that's just not wired correctly or something. 

If there's anyhelp on this, it would be greatly appreciated, because this is extremely frustrating at this point.

Yeah, I tried a full factory reset, which I had trouble to do as it was asking me for my password and some of those unworking keys are needed. I finally managed to do it and the problem is still here. So it's definitely a hardware problem... 

But it is a really disappointing to here that even with a repair the problem will come back... That computer was a great product in every other point in my opinion... 

Changing the keyboard is quite simple and inexpensive. If there is a warranty, send it to dell

Hi,

I'm awaiting a response to earlier message. Do get back to me at your earliest convenience.

I just bought Inspiron 7590 1 month only and I have the same problem.

In my case, the q key doesn't work sometimes or press key 1 time but I get double - triple letters. I had updated all drivers and BIOS but didn't help. I had tested typing this key in the BIOS  and I got the same result. but it's work fine on a USB keyboard

I hope the root cause of this problem isn't from the hardware.

I just changed new keyboard on my laptop. Currently It's work fine. However if I'll have any problems. I'll tell you.

I had my keyboard changed about a week ago.

My computer worked just fine for a fews days, and now the problem is coming back, little by little, the keys stop working from time to time, just like it did when the problem came the first time...

So problem still not fixed even if the keyboard was changed.

I had this problem since day 1 with my laptop. What I tried to do is to open the laptop and reseat the keyboard connector(located next to the battery connector) and it has been working fine for the last 6 months cheers.

Hey all, had the exact same problem and after 2 keyboard replacements and some testing(with the old keyboards) i discovered that the blue keyboard ribbon cable wasn't holding contact with the motherboard inside of the connector.

Since its well and truly out of warranty I ended up quick fixing by sliding a small piece of a drinking straw between the edge of the motherboard and ribbon cable just to adjust the angle that the cable sits inside of the connector.

I don't think i have explained it very well but if you gently pull up on the blue keyboard ribbon cable (right next to the battery) by its plastic handle and try the affected keys again you hopefully they will work again.

Hope this helps to anyone still having these issues today!
