Intel Ivy Sandy Bridge CPU in my dell laptop

Today I want to write a note on the CPU used in my dell laptop which I wanted to repair. I wanted to know the circuit schematic of this dell laptop before I repair. So I have going through the dell laptop schematic for a while now. I started to look into the power supply distribution and sequence of powering on the different components and ICs on the dell laptop motherboard. I wrote about this in the note how laptops and PCs start up? I also wrote about different ICs and components used. I found that the following the powering on sequence that the main ICs are NPCE885PA0DX - I/O controller chip, the Panther Point PCH(Platform Controller Hub) chipset and the Ivy Sandy Bridge Intel CPU among the other ICs related to the I/O such as LCD display, Keyboard, HDD, RAM, connection related ICs for the USB, Ethernet, WiFi etc.

So here I am going write a note on the Ivy Sandy Bridge Intel CPU that is used in my dell laptop. I found out the Sandy Bridge is codename for 32nm microarchitecture and Ivy is codename for Intel's 22nm microarchitecture. Ivy Sandy Bridge means that the Sandy Bridge microarchitecture is upgraded from 32nm to 22nm with the use of FinFET(3D) new tri-gate MOSFET technology. The Ivy Sandy Bridge Intel CPU is 3rd generation Intel CPU which news Intel i3,i5 and i7 processors.

Below picture shows the Intel CPU Ivy Sandy Bridge in my dell laptop.

The block diagram below shows how this Intel CPU Ivy Sandy Bridge is connected to the rest of the circuit including the PCH(Platform Controller Hub) chipset in my dell laptop schematic.

The actual circuit schematic connection are shown below.

CPU(PCIE, DMI, FDI)

This circuit schematic below shows Intel Ivy Sandy Bridge CPU connection to to PCI Express (PCIe), DMI (Direct Media Interface) and FDI (Flexible Display Interface). These are mainly connection to the Intel Panther Point PCH chipset.

CPU(THERMAL, CLOCK, PM)

This is connection between the Intel Ivy Sandy Bridge CPU to Thermal IC (NCT7718W), to the clocking circuit and to the power management IC circuit.

CPU (DDR)

The below circuit schematic shows connection between the Intel CPU Ivy Sandy Bridge and the RAM DDR memory.

These are the many connections of the Intel Ivy Sandy Bridge CPU to the most of the parts or IC on the motherboard PCB. There are other connections which I have omitted here because they are really only for the core CPU power supply and the rest of the CPU power supply.

I hope to read this again one day in the future.
