ALL ABOUT SOUTH BRIDGE CHIP SET VOLTAGE AND SIGNALS

IT IS VERY IMPORTANT FOR LAPTOP AND DESKTOP MOTHERBOARD REPAIRING, WHAT ARE THE MAIN FUNCTIONS OF SOUTH BRIDGE IC.



1.RTC circuit: Southbridge internal real time clock circuit, also called CMOS circuits, mainly used to store the time and date and ESCD (Extended System Configuration Data).

2. Return circuit (module): is part of the South Bridge internal power management module, all the signals are thus SLP module circuit is completed.

3.VccSus: back module (module restart) power ICH4 inside, there are three V5REF_Sus VccSus3_3 VccSus1_5 and power.

Wherein VccSus3_3 return module I / O buffer circuit power;

VccSus1_5 is mains voltage return module '

V5REF_Sus return module 5V reference voltage input.

4.PWROK: This signal is sent to the ICH4M representative ICH4 core voltage of the normal power-good signal from the outside, when PWROK canceled, ICH4 will refer PCIRST #.

It is worth noting that in three of the RTC clock, PWROK failure. So as to ensure ICH4 produce normal PCIR…

TOSHIBA LAPTOP RESTARTING PROBLEM SOLVED (NEC CAPACITOR DAMAGED).

Toshiba Laptop Repair, Satellite L300 / A300 Restarting Problem Solved.





The problem is very common in these models of notebooks (Toshiba satellite A300 and L300) freezes or restarts on AC power plug in.
It works on battery power and charges when power is connected on shutdown.
When it’s powered on with the AC plug connected may freeze when on, or remains on for a little while before freezing or restarts.




This should be done with a IR Soldering station, but can be also done with a Hot air station or Hot air gun.
1. Remove all the removable components from the motherboard like Ram, Wireless card, CPU etc.
2. Cover the surrounding area near the capacitor with aluminum foil and apply some flux paste (soldering paste) all around the capacitor.
3. Using a Hot air gun you can start to heath the capacitor and use a tweezers to touch it from the side. When it is moving that means that the soldering alloy reached the melting point.
4. Remove the bad cap with a Suction pen, and apply the new ca…

DESKTOP MOTHERBOARD SOCKET LGA 775 PIN DAMAGED SOLUTION

SOCKET LGA 775 PIN REPAIR METHOD.



SOCKET 775 DAMAGEDPIN REPAIR METHOD.

Tools:
1 pair of angle point tweezers - others work but I liked flat angle points.
1 Stanley or break off tip wide flat knife. It needs to be wide so it’s strong. Set the blade projection to about 1.5 inches from its sleeve support.
1 steel pin - standard dress maker’s type.
1 pair of wide nose pliers - to hold pin.
1 pair of sharp scissors.
1 x Strong 'halogen type' pedestal light - being able to position and angle the head of the lamp is a big help when viewing the project through the magnifying glasses. Aim it so that you have a great close up view.

Materials:
1 reject 775 socket from dead board - this is where you will get the pin/pins needed. Keep an eye on your local PC shops skip bins - or preferably just go ask their technicians for a dead 775 bare board.

Start

1. Prepare pin: Use a flat blade screw driver and lever part of the socket from the dead board. As it breaks away keep all the piec…
