How to Install Speakers on your Computer/Laptop!!!

The body control system consists of the following 3 modules:
• The Dash Integration Module (DIM)
• The Instrument Panel Module (IPM)
• The Rear Integration Module (RIM)
Each of the 3 body control modules integrate a number of functional systems under the control of a single module. Each module is connected to the Class 2 serial data circuit, many of the control functions are implemented by Class 2 messages.

What system (S) are you having problems with ?
Rear Integration Module (RIM)
The various RIM inputs and outputs are described in the corresponding functional areas as indicated on the RIM electrical schematics.
The RIM functions include the following:
• Automatic level control
• CIGAR relay control
• Class 2 communication requiring RIM interaction
• Content theft deterrent
• Fuel door control
• Fuel level sensor input
• Heated seat control
• HVAC blower control
• LK/CYL relay control
• Park brake relay control
• Rear defog relay control
• Rear park assist chime control
• Retained accessory power (RAP) relay control
• Reverse relay control
• Transmission shift inhibit
• Trunk release relay control
• Various controls for the interior lamps

Instrument Panel Integration Module (IPM)
The various IPM input and output circuits are described in the corresponding areas as indicated on the IPM electrical schematics.
The IPM functions include the following:
• 54 volt VF display input
• Ambient light sensor input
• Class 2 communication requiring IPM interaction
• Fog lamp switch inputs
• Front HVAC air delivery controls
• Front HVAC sensor inputs
• Front HVAC temperature controls
• Fuel door and rear compartment lid release switch input
• Hazard switch input
• HUD active control
• Instrument panel lamps dimmer switch input
• Ignition switch headlight control
• Interior lamps switch input
• Key in ignition switch input
• Traction control switch input
• Twilight sentinel delay input

Dash Integration Module (DIM)
The various DIM input and output circuits are described in the corresponding functional areas as indicated on the DIM electrical schematics.
The DIM functions include the following:
• Class 2 communication requiring DIM interaction.
• Control of exterior lamps.
• Control of front fog lights.
• Control of the headlights.
• Headlamps on with wiper input.
• Hood ajar switch input w/export.
• Horn relay control.
• Interior lamps incandescent dimming.
• Low side temperature for HVAC compressor.
• Power moding control over Class 2 serial data circuit.
• Reverse lockout solenoid control.
• Steering wheel controls input.
• Storage of the clock settings and, sending a message out on the class 2 serial data circuit in response to requests from other modules.

If your monitor has various input sources, make sure it's on the correct input source in the main/input menu. If that's not the problem double check the cable for bent pins also make sure if you have a video card with DUAL dvi outputs that your using the correct one.. as the other one might be secondary and non-functional. It's possible but highly unlikely if you unplugged the DVI cable while the monitored was still powered on it could have damaged the video card of the computer or mainboard of the LCD monitor. When in doubt try another DVI cable if all else fails.. if you have another DVI monitor (thats a known good) try that also to make sure that the video card is not the problem.

Basic Input Output Service....It is the chip on motherboard ,in which all instruction written for identifying the hardware

Looks like you're right, I did not see any Lenovo replacement jacks either. You might try looking at the IBM Thinkpad jacks for various models to see if you can find the same jack.

I've repaired 3 laptops with this problem. Rather than replacing the jack on the mainboard I wired a "pigtail" to the mainboard and then zip tied a female connector to the back of the laptop itself. I did this because the mainboards were pretty beat up from the heat the original jack produced as it began to loosen. The end result is not as pretty as the original jack, but it absolutely takes all the stress off the mainboard. Those computers will never have this problem again.

Good luck.
