It depends on the extent of the damage caused by the spill. Clean the motherboard with isopropyl alcohol and cotton wool, like I did in the video. (The mission is to remove any sign of liquid) But if the liquid has caused some chips or fets to fail, they must be replaced. But liquid spill shouldn't damage anything on the board if prompt corrective measures were taken.

Check the condition of the fets, caps, resistors. Check voltage flows

Sure. Just drop ISO file in it. That's all

@ okay… pls, what do you use to convert them to ISO file format?

@CHIWIS-Tv power iso is one. Make research on iso converter

Exactly, I wouldn't recommend anyone to buy Zealot.

Ok so can I learn laptop repair from you

Absolutely

The BIOS?

@zilicontech No BIOS, The same eight-pin IC that is voltage feeding

25Q128A13ECO

I'm a little bit confused. This is a memory chip of 128M Bit. I don't think it is a power MOSFET. If you need the firmware, you can search for the firmware with the PC's name. Since it is a memory chip, its content will vary from PC to PC. I don't know if any of these make sense to you

@@zilicontech I can't get my point across It is possible to talk on WhatsApp and I will send a picture of the piece, thank you very much

There is a better way. It will give you ending stream of income. You can save up the income and buy anything of your choosing. What is that? You may ask. It is simply by developing sellable skill(s). For example computer repair skill. That's why I'm here, and I've made tonnes of videos on computer repairs. Start from the repair masterclass, and build from there. I'm here to help if you need me

Have you tried BIOS reset?

Sure, check my channel for such video

Definitely.

I don't. I fix. You can check on Aliexpress for its availability

We're you the one that PM me?

There are pending questions you haven't answered.

Good input

You are welcome

Try BIOS reset. If it persists, reprogram the BIOS.

@zilicontech Tried to do that but a screen appears saying that it could be missing or corrupted

That means there was a display. Your PC should be able to work afterward. Quote the exact message it displayed

@@zilicontech Sorry for the late reply. "The BIOS recovery files cannot be found ro the files are corrupted. Using another computer and a USB flash drive, download the latest BIOS file from the HP website and create a BIOS USB recovery drive for the PC that needs recovery. Insert the BIOS USB recovery drive into the PC that needs recovery and restart the PC." (Btw, it actually misspells "ro the files")

A way out has been presented. Follow the suggestion judiciously. Did you remove the SSD/HDD that is on the PC?

Send it in, for repair. Or Attempt to have it repaired yourself, using what I did as a guide.

Yeah. Not a bulletproof, when the HDD/ SSD failed (hardware error) But trust me, it is a first-aid everyone must know and activated. Cloning or image backup is another layer of safety net should there be a hardware failure. You can easily deploy it on another device and move on.

It is always better to be safe

@zilicontech Definitely! 😎

Sorry about your experience. What do you think was responsible for your inability to understand what I was saying?

if you cant understand then you need to get your ears checked. you know you can turn on subtitles even though it is auto generated it gives good enough captions for you to understand what he saying

@@zilicontech You're pronunciation. This happens a lot on RUclips with people from other countries who publish in English, rather than their own mother-tongue, and maybe because their English is very good and they feel confident about it, they speak quickly as if they were talking to their friends. Unfortunately for them, they don't realize that to native speakers who are used to English being spoken by their own mother-tongue culture and population (which is 98% of us!), it sounds like inaudible gibberish. Very difficult to listen to. You simply need to pronounce words properly and correctly, and speak slowly. Listen to mother-tongue speakers on RUclips, then listen to your own videos again, and learn the difference. Also you're voice is low and your speech very "monotone", which makes it even more difficult to discern what you're saying. Good luck

@@reddddzzz LOL Don't be ridiculous and pretentious. It is him who is expecting us to understand him for his own gain. We are not the ones who need to make an effort. He's the one who needs to make sure he's understood. Silly! LOL

@@reddddzzz Dude! Do you think I'm telling him that FOR ME?? It's for HIS OWN benefit. Stupid.

Sure, distance is not a barrier. Reach out to me on one of my socials

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

@@zilicontech sir, after looking the schematic diagram of HP 840 G2, why i can't find the reference number in my motherboard? (example resistor of R7409, R7410........etc is missing in my motherboard.)

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

Get the datasheet for the chip, identify what those pins are. I don't have the board with me.

Most definitely

What is wrong with it

I use EZP 2019. I believe there is update now. Check Aliexpress

Sure. Check the hall sensor with Multimeter if there is voltage at the in and out pins

@zilicontech thank you

@@Mr.Double_R but note that the 9470m is not the same with 9480m, make sure you identify where the hall sensor is

@@zilicontech yeah sure! Thanks for advice. Love from Bangladesh ❤️🇧🇩

That means cpu vcore is missing. Check the resistance of the cpu vcore

Check the chip meant to produce the cpu vcore if the enable, vcc pin are present

Thanks for ur reply, sir! Yesterday, i forgot to tell you is that i turn back the motherboard and check the first pin of ? power core, zero voltage. (3.2v at ur video)

@@fearnwang336 what's the part number of the chip you took the reading from? List the pin and the value

Sir, i took reading from the first one, zero voltage is ?inductor marking L6610 (R24-532-ZBA) (near cpu), then i check the back of motherboard as ur video (8pin, v393RDA, marking as u7400) its first pin also no voltage at all. Sorry to tell u that i m just a beginner. if i make something to annoye you, plz forgive me.

Did you try other things I said?

@zilicontech for it it had 3amber 5 whites power rail issue,really failed to find the problem

It is not the same with 2 amber. You have to understand the meaning of the code first, only then you will be able to know the next step to take.

You watched the short video. Check my channel for the full video
