Alright lets become down to it, I have an Alienware M17x R3 from 2012, model number P11E, at starting time it started with a single central not wanting to work, and so it spread to a agglomeration of keys non wanting to work, and others inputting the wrong letter of the alphabet, got to the point that you lot cant boot to windows with the keyboard connected to the board or else the laptop volition beep eternally as if a cardinal was existence held down (tested this multiple times with an external keyboard while the internal one was disconnected).
An external USB keyboard works commonly, and ive uninstalled and reinstalled every driver i can recall of that could fifty-fifty remotely exist related to the keyboard, besides as tried dissimilar BIOS versions to meet if theres a problem there, but the problem persists. Ive tried cycling capacitors, different operating systems, even ownership a new internal keyboard and swapping it out (two new ones actually), ive swapped the keyboard to motherboard flex for a new one and the trouble persists, ive searched dozens of forums with like issues and theyve all either been resolved with software/driver updates/re-installs or keyboard replacement, ive tried everything to the point that im now checking the motherboard itself (correct motherboard schematic at hand) for shorts or bad contacts that might exist causing the trouble (im still searching).
I want to get to the lesser of this, and i want to know if theres some help that someone out at that place tin can offer, or if someone out there with same experience managed to solve this upshot and how. Any assistance, and i do mean whatsoever help is appreciated much. Thanks in advance, if further info is required on the machine just ask, hopefully a solution tin can be found and laid to rest in this forum for anyone else that might run into this issue.

Should analyze that ive already tried this, as well every bit replaced the flex to which the keyboard connects to, and i too mentioned that i replaced the keyboard as well for the correct one (these keyboards come in different color coding and not just whatsoever color will work with any motherboard).

When i replaced the keyboard and the flex which the keyboard connects to, i made sure they where both uniform extensively earlier hand as they are expensive. Contacting Dell back up is not an option for me either. If youre wondering what flex im talking almost, search office number 9T3CX, my compatible keyboard model number is NSK-D8D01.
