sir, after watching ur video repeatedly, i check my laptop again and found that U7400 semiconductor is default (pin 1 and 7 is no voltage at all, pin 8 has 5v and pin 2,3,5,6 have round about 1.2v). I would like to know is that 1). direct replace this U7400, will it correct the problem? 2). do i need to flash the BIOS chip and update firmware as like ur video label as u365 ?
I am currently having this issue and i am in bayelsa State, Nigeria. I want to as: 1. What's the cause of this happening, could it be the way the system was used or jud a normal problem. 2. Where's your office? 3. How muxh averagely does it xost to fix this problem?
1. It is a common problem with the hp 2. Ile-Ife, Osun State 3. 15k on an average. Have you exhausted all the troubleshooting steps you can do on your own?
sir, on 10:53, about u365 chip, you said that if pin1or7 is no voltage, it ll be abnormal. But what is the cause that pin 5 and 6 is without voltage and other have 3.3v (pin1,2,3,7,8)?

Not all named parts on the schematics is available on the board. There'll be a sign that will indicate the part was not included. Another method is to compare the PCB with another exact type
Good one! Elitebook PCs requires two voltages to be present. The white and yellow can also indicate charger error. And this is tricky, you might be in confusion when same charger charges another PC that doesn't require the two voltages to be present before the PC can charge or turn on. The easy way out is to check the charger with multimeter for voltages presence or you swap the charger with another same-working PC. I'm glad you were able to record success in this repair
What's the name of your laptop? Can you give a comprehensive report of the PC's current state? What happened before it got to the current state? All minute details are important
ok. I'll work on the subtitle so that you'll be able to get the accurate translation in French. let me know if you need further assistance with your laptop. I will be more than ready to help you.

@@zilicontech thank you.
But, after repairing it will it reoccur in the nearest future?
nay
I have this problem 😢

should i replace this chip to correct problem? or to trace the cause why pin 5&6 is no voltage?
No, don't replace.
Check where 5 and 6 comes from

Get the datasheet for the chip, identify what those pins are.
I don't have the board with me.
Plz, how can I reach you?
I have a similar complaint with my 6360b hp
you can reach out to me @zilicon on telegram
is steve jobs trying to reach us lol
Sory, can you share link Bin file for HP 840 G2? Thankyou so much..
I will ASAP
Conversely, I can send it to you directly. Reach out to me on any of my social links
For me the adapter was was the problem one of the wire was cut and now fixed. and plug-in light keep blinked white and yellow.
Good one!

Me cause, only remove the battery and put again and ok
I'm glad your PC is ok now.
Most PC hiccups can be solved by simply removing source of power and consequently draining the PC of residual voltage.
Did you still experience the problem thereafter
