Course content

1 section • 7 lectures • 2h 30m total length

ADPTER INPUT AND BATTERY CHARGING SECTION18:10
this video explain how adapter voltages flow in the motherboard. how battery charge and how voltage switch from adapter to battery when we remove adapter. how to solve if adopter voltage not reach at current sensing resister. what to do if battery not charging
3.3volt and 5 volt section working principle13:20
this section explain how 3.3v linear going to SIO and how sio end enable to this buck converter and how 3.3alw and 5valw generate
POWER ON SECTION20:55
this video explain how laptop motherboard power on . how SIO and PCH communicate each other. How signals flow one after another and how to diagnose which chip is bad
power on sequence how motherboard turn on18:56
this video explain details about how voltages are flow from different stages and their signals. after pressing power button which signals are proceed. which test signals we have to check if motherboard is dead
how to read schematics diagram33:47
this video explain how to read schematics diagram in very easy way. test point in diagram
how to use board viewer of motherboard20:43
from this video you will learn how to use Flex board view application. board viewer is very easy application for finding component's on the motherboard. we can locate signals and test point voltages
new generation laptop motherboard working principle24:16
new generation laptop power sequence. this video explain what are test point if motherboard is not powering on 4th generation onwards. this types of motherboard dont have PCH only CPU is there called SOC

Requirements

basic electronics knowledge, tool like multimeter, hot air gun, dc power supply and bios programmer
