Keyboard latency/connectivity issues caused by BIOS update?
I installed a BIOS update yesterday via Dell SupportAssist on my Dell G3 15 3579 and ever since installing it my keyboard hasn't been working properly (I'm having to type this with the on-screen keyboard because of it). Essentially what is happening is I'll try to press a key and either A) Nothing will happen B) Multiple characters will be typed. Rarely do I get a proper response from the keyboard. (For example, dddd - I hit the a, b, c, D, E, f, and g keys twice each, but somehow got 4 ds but none of the other characters posted.) This is not a hardware issue. I have already tried uninstalling the device + drivers and rebooting, as well as updating the drivers, running the DISM commands in command prompt, troubleshooting the keyboard, and doing basically everything else listed on these two sites.

http://prntscr.com/t06jzq with this being the only exception.
http://prntscr.com/t06lvo idk if this is relevant or not, but I only use the built-in keyboard, I've never even plugged in another keyboard, but there are five keyboards listed, even after uninstalling them all and rebooting.
Please get back to me ASAP. I need to fix this.

Battery is now stuck at 0%. It says "plugged in, charging". Probably another error caused by the faulty BIOS update. This is preventing me from reverting to 1.11.0, though.

Experienced the same thing with my G3 3579. Worked fine until we installed the BIOS update. After installing, having the same latency issues with keyboard and the battery won't charge.

So I gave up trying to fix it myself and took it into a very experienced IT guy. Basically, this cannot be fixed. The BIOS update contains an Intel Security update (or something like that), so even once you get around the battery issue, it cannot be downgraded or reverted. You also cannot perform a factory reset. So we're stuck waiting for Dell to release a hotfix for this garbage BIOS update.

So I finally found a work around for this. While the built in keyboard doesn't interface correctly, external USB keyboards do. This obviously doesn't fix the battery issue, but it at least makes the pc useable.

@ItsBigJ
Apologies thought you were aware that external USB Keyboards and mouse do work, beats purpose of laptop right enough.
Anyway, glad to say the new BIOS update given to me by Nilesh at Dell support does work and resolved the issues that i had.
Took a while but Dell got there
Cheers guys

So glad to hear that this update worked. How were you able to get around the battery issue? I cannot install the update because the battery is less than 10%.

Sorry cant really comment on battery issue as i never experienced this, battery was fully charged i expect.
Will it not update whilst plugged in ???
What i would advise is removing battery (Or disconnecting) run off mains and do BIOS update then reconnect.
Otherwise throw it out to Dell Support for advice, Nilesh certainly helped me (Took Time for initial response though).

After some effort, I managed to resolve the issue. The BIOS failed to update properly, resulting in keyboard and battery charging issues. Attempts to reinstall or downgrade the BIOS failed due to low battery. To fix it, I successfully reinstalled the latest BIOS version. Everything is now functioning normally.
For bypassing the low battery error during BIOS update, follow these steps: https://www.dell.com/support/kbdoc/en-au/000134938/forcing-a-bios-update-without-the-ac-adapter-attached-on-a-dell-laptop
Remember to rename the BIOS exe file to 'bios' for easier CMD command entry.
If you getting this error message "could not find valid policy or resource payload" you are not writing the correct path of bios file.
