Desktop Motherboard Chip Level Details Before Power On Voltage and Signal------------AFTER POWER ON VOLTAGE-----------------------------
Whats app: +91 8010708080,
Before you turn on power 5VSB is always high! while you plug in the power supply which offers the standby voltage to some chipsets that can boot MB up!
PS_ON# must be touched off low to turn MB on !
If PS_ON# were low, every voltages from power supply will operate!
Before you boot up the board, you should measure the Power Button#.
#, you must know this signal is acted by low, initially it is high.
When 5VSB and 3VSB send to SIO and SB
SIO will send this signal ‘’RSMRST# ’’ to SB’s boot up circuit to notice the MB is ready to boot up! If this signal is Lo, you can’t boot up MB.
Do you know when RSMRST# is Lo?
The answer is unplug the ATX connector!

hello, I have an asus kv8x, with atleton 64, old stuff, I use it to play with mame, now it doesn't turn on anymore, I checked all the outputs of the power supply, and everything is ok, (with green and black wire shorted yes active) how do i know if it is the motherboard, which does not send the consent to the psu? or the cpu is faulty? without cpu, the psu, you should activate the same by pressing the button, under normal conditions?
Hello Sir, mera PC SMPS ka ek Polyster cap. kharab ho gaya hai. uska
value CL21, 105K, 250V hai, toh uska replacement value ke capacitor kaun
kaun sa hoga? kya higher value ke capacitor lagane se problem ho sakte
hain? My second Question, kiya chip level repairing online ka experience live class jaisa hi hoga, i mean to say, kiya sabkuch sikhne ko milega jaise kuch special tips or tricks. I m from Assam. Thank you so much for your valuable informations!
Sir same video laptop block diagram par bhi banao

Hello sir without RTC 32.768kHz can we get RSMRST signal in sio
If yes how posible ?
If no.. plz check your before poweron step checking procedure in video
Thanks
very helpful video sir ji desktop motherboard ka partical o bhi batado na sir.
sir aap LCIIT channel ke sabhi video dekhe, desktop motherboard se related bahut kuch aapko knowledge mil jaayega
LCIIT- Laptop Desktop Chip Level Training Channel
जी,
आप बहुत अछ्छे से सिखाते हैं। मैं अछ्छे से सीख रहा हुँ। दन्यवाद।
my friend, i think the controller pwm not send pulses on DRIVER... just only send stable voltage, and the driver send pulses to mosfets. And add this : you have 3 mode of supply in IT (super io) : 1_ with vbat 2_ with ps connected on motherboard without start (3vsb ) and 3_ when you start is the avcc3 (power analog) this is for IO "ITE" general. some brands change this terms.etc but this video is genial!
There are 4 stage of any buck converter regulator. First controller, who send pwm to drivers, then drivers generate high gate, low gate frequency to regulator that is upper mosfet and lower mosfet. after that last stage is filteration where coil and capacitor used.
wonderful ,but could you repite this video in english sir?
Good videos
thanks

Hi,
I have doubt about my computer working on suddenly monitor goes off but system running what is the issue majorly
Can you help me
Thanks
Check RAM
hello sir maine no display ke south bridge faulty wala video dekha to waha par yeh bataya ja raha hai ki no display ke case par hame plt reset check karna hai. agar reset mil raha hai to south bridge ok hai. problem kisi aur section me hai. aur yeh bhi bataya gaya hai ki south bridge tab plt reset generate karta hai jab ise north bridge, clock,cpu core ,etc se power good milta hai. toh mera confuaion yeh hai ki agar kisi aur aection me problem hai to kiya woh power good signal generate karega. agar power good signal generate nahi karega to south bridge plt reset generate nahi karega. to hame kaise pata saleg ki south bridge faulty hai ya phir koi aur section faulty hai
according to power sequence , south bridge ke baad bios, northbridge, ram etc. ka kaam start hota hai. agar plt reset aa raha hai to iska matlab ki board ki sabhi supply ok hai, jaise ram circuit ki supply ok hai lekin koi jaruri nhi ki ram ok hi ho, isi tarah bios ok ho ya na ho plt reset ok hoga.
plt reset ok hoga lekin is baat ki surety nhi ki cpu reset, dram reset etc. ok hi ho.
sir mujhe 800 g2 tiny schematic diagram nahi mil raha h

ok sir thanks
ok sir agy sa hm khayal rakha ga plz power sequence wali jo abhi jo upload ki thi plz upload krda or turant download krlia kra ga plz
