SWITCH CONTAINS TWO TYPES LEDs:
:POWER LED.
: PORT LED.
Power LED used to determine the power status whereas the port LEDs are used to indicate
the port status. Number of port LEDs present on the switch.The user can determine the status of switch , depending on the status of the LED. The green light on the LED indicates that the LED
is powered on.The status of a port can be checking the status of the port LED. All the port which
have green lights at their respective ports are inactive.
Replace Memory:-
There are two basic types of memory currently used: DDR2 and DDR3. is still available but unlike to be installed in any currently sold PCs. Beyond the type of memory,each memory type also has a related speed to that RAM as well.Below is a chart the order of the type and speed in order of slowest to fastest:
:- DDR 333 MHz or PC2 - 2700
:- DDR 400 MHz or PC3 - 3200
:- DDR2 533 MHz or PC2 - 4200
:- DDR2 667 MHz or PC2 - 5300/PC2-5400
:- DDR2 800 MHz or PC2 - 6400
:- DDR3 1066 MHz or PC3 - 8500
:- DDR3 1333 MHz or PC3 -10600/PC3-10666
:- DDR3 1600 MHz or PC3 - 12800
These speed are all relative to the theoretical bandwidths of each type of memory at its given clock speed when compered to another. A computer system will only be useds comparison when the CPU
is identical between the two systems.
Troubleshooting Motherboard:-
1.Chek the CMOS battery voltage for 3 volts ; if this is less"you may not get the display.
2. Check motherboard for cracks on account of overheating of equipment.
3. Check if processor getting core voltage. Put your finger on tap of the processor so that you can understand whether processor is getting voltage or not. if loos connection heated then processor
or power section problem.
