17 R4, coin cell failure, wire
I wanted to replace my thermal paste, while doing so i managed to pull fan wires out from motherboard, to fit those back in i had to remove motherboard, for that i tried removing the coin cell battery connector by pulling the wire and the wire snapped, i managed to remove the connector and replace it with a brand new coin cell batter, now i am sure the coin cell connector is fit properly to it respective connector on motherboard. Yet when i try to switch on Laptop starts with 2 red light beeps and three blue , once powered on completely it starts in 3,1 pattern , no display, no beep sound. and it continues with 3,1 pattern till manually switching off the power button. I tried by keeping the charger connected without power for 30 minutes or so and then starting it, still same, What could be the issue?

Hi @akshay22 welcome to this free user to user Alienware laptop discussion forum. This is not Dell Support.
Support for Alienware 17 R4, Service Manual, Diagnostics Light Codes says 2,3 = No memory or RAM (Random-Access Memory) detected, and 3.1 = Coin-cell battery failure.
Code 2,3 is usually fixed by cleaning and reseating the RAM cards. Touching the RAM Card's electrical connections is not recommended, it can leave human oil residue behind. The System Board (aka Motherboard) gets covered in dust, the extraction fan blades collect debris, etc. and a good clean with can of dry air, or air puffer is always recommended when laptop base is opened.
Code 3.1 is usually fixed by Clearing CMOS settings. The coin battery wire's plug is captivated in its socket, and pulling the wire so that the wire snapped, might have damaged the System Board's socket. Please use a bright light to investigate if the coin battery's plug is correctly captivated and if one or both the socket's internal captivation tabs are broken.
