Finally fially somebody explained this clearly. Got answers why the MB is not starting when no coin battery is inserted: PCH core not getting voltage due to missing LDO 3.3V, possible a faulty (broken) diode. Thank you!
Please sir, I HAVE HP MOTHERBOARD WHEN I PLUG ADAPTER WITHOUT CMOS POWERS ON WELL, WITH CMOS NOT POWER ON I TRIED TO REPLACE WITH NEW STILL SAME PROBLEM. I CHECKED RTC SECTION EVERYTHING WAS OK. PLEASE SIR WHAT WHY IS IT THat I need to first reset motherboard first to power on Isit INTERNAL PCH RTC SECTION WHICH IS FAULTY, AND I NEED TO REPLACE PCH CHIP PLEASE SIR WHAT COULD BE CAUSE AND SOLUTION FOR SUCH ACASE
Hi friend I have had this issue ones on a Samsung laptop where it works with the CMOS battery disconnected, and it doesn't work when connecting it back. It turned out to be a low battery where it kinda gives a voltage to the Bios and causes it to stuck and needed to be reset . But I think you mentioned that you've already replaced it with a new battery. Is that right..? If you did, then please make sure it has the correct voltage (the new battery). If it does have correct voltage, you need to check and look for a dual diode package and check before it and after it for a voltage of 3 to 3.3 volts with the battery connected and with and without power adapter connected You must not get less than 3 volts...
@@FixTronics ohh OK sir, i have talked about this, because when I plug in adapter in Mother board it's power on well, then When I switch off properly with its power button switch it switches off well. Without removing its adapter. But when I try to switch on, it cannot switch on yet it has switched off properly, this time without cmos Beacuse even I tried to switch on from EC chip pin pwrbtn# in it does not switch on but can switch off well
This is very very satisfying, you really do understand the concept.

Thank you brother
if those signals are missing, the laptop dont start???i love your explanations dude, you are rockkkkk
Yes of course it won't start with any missing signal
I wish you all the best brother

Thank you bro
Supper video
Thank you
Thank you sir 🙏
Welcome brother
Exellent. Thank you.
Thanks brother
Who this make dislike . Good explanation
Thank you so much brother
Sir , is RTC 3v missing common complaint on laptop??
It isn't common but it happens
