I just purchased an Alienware 17R3 running Windows 10.
My BIOS, drivers and Alienware/Dell applications are up to date, thanks to my tech support phone call today.
When I start my laptop, if it has been sitting more than 30 minutes, I have several keys fail to respond.
The keys are 4, 5, e, t y, f, g, v, b. ( I have to double check to be sure of the exact keys.)
If I leave the laptop on for 5-10 minuets they will eventually start to work. 
Once it starts working, I can use the computer as much as I want to, restart it or shut it off for less than 30 minutes, and the keys will continue to work.
I then ran the two tests.
I started the computer, after letting it sit for 30 minutes, and verified the keys mentioned did not work. I then attached a Bluetooth keyboard and all of the keys did work. I then tried the laptop keyboard again, and it still did not work.  
I let the computer sit and verified the e key did not work. I then rebooted the laptop using a clonezilla usb key. All of the keys worked immediately.
I then restarted the laptop and booted into windows. All of the keys immediately worked.
* I don't know if it has any bearing on the situation, but in order to boot from the USB stick, i had to turn off UEFA and enable legacy boot support. I then had to re-enable UEFA in order to boot from windows.
I am kind of stumped. I would rather not reinstall windows.
Any thoughts?

Have you run the Dell diagnostics (when the problem was present - let it sit for a while before starting the test)?

As I recall, they have a keyboard test built into their diagnostics.


When we see problems like this at work, it's usually beause someone has slammed their hand down on the keyboard in that area, or that they have closed the lid on an object that was laying on the keyboard.

Other possible causes are a defect in the circuitry of the keyboard that changes as the broken part heats up and expands (and then breaks contact, rendering that section inoperable).
