Laptop Hardware Repair (From Basic)

[Digital Funland]

I want resources to learn the basic laptop repairing at hardware. I am looking for resources to start.
Can any one suggest me some good learning resources to start.

@Digital Funland You mentioned in your introduction that you use various AI tools. What did they say? Technibble is really for topics that can't be found with a basic search.

@seashore Yes I have said that I have done a computer Hardware Technician course of six months with 2 months of experience on computer repair shop. I have a good knowledge of computer's and their components. But I am asking for materials that teach from basics is because I want to trace fault with logic. Like if we are getting this problem in computer then why. How loptop works. like if there is a fault in motherboard I can't don anything because I have not studied that How things on motherboard works like IC's , Fat's. I think you got the point.

What I actually want to learn is fault tracing and then repairing.

That's not "basics." That's wildly advanced, and most shops are not equipped to do this. And given the cost involved even with the diagnosis, replacement rather than repair is the norm.

I have nothing to offer you in terms of what you're looking for, other than to disabuse you of the idea that it falls under "the basics." Fundamentals that are very seldom employed "in the field" can't be considered "the basics."

@britechguy Well I want to learn about motherboard components failure and their replacement.

The computer course I have done is all theory the on practical I have done is when started working in the repair shop.

Well the shop is in a small town. So Mostly people have old pcs and laptops like core 2 duo but other people who use for work or can afford have good pcs and laptops normally we see core 2 duo , i3 2nd gen to i5 4th gen and sometime even i5 6th gen but occasionly we even get to see i5 10th gen and i7 10th gen. Many times people have issue in the motherboard of their computer.

You might not believe but hp6005 with display problem usually gives display when we give heat to two ic's with heatsink as a last resort and they give display 60 percent of the times

Well I want to learn about motherboard components failure and their replacement.

Which is fine. But that doesn't change my point that this is not "the basics" but is very advanced work, even if it's being done on ancient hardware.

You're asking about things that, while foundational, are not in any meaningful sense basic. I can count on less than one hand the number of people I know that actually do the sort of work you describe.

I hope you may get some reference material from others here, but it won't be "basic" in any meaningful sense.

@britechguy I got your point.
Because of the old hardware I face and see these issue's some what commonly but they don't happen without a good cause like a decade old computer can have these types of issue's easily because those pc's are working way past their time that was meant for them.

That's why I thought that it was common repair skill that almost every computer repair person had or should have. By the way thanks..

You're looking for component level information and all major OEM's intentionally prevent that information from being readily available. I've taken a number of OEM (Dell, Apple, HP, Compaq, Toshiba, Sony) provided courses over the year and none ever touched on that level. Take it down to the board or device level and replace. To add to that then continuing shrinking of packages means even more "stuff" get's packed into the same area. And this goes for pretty much anything that has IC's, etc.

Technibble is about IT service businesses where the business is just as important, if not even more so, than technical skills.

In this business, speed and reliability matter most.
No professional tech is going to waste billable hours trying to repair a failed motherboard when a replacement gets the client back up faster and with less risk.
Motherboard repairs are rarely cost-effective, can’t usually be billed for the true time involved, and if the board fails again, you’ll be wearing both the cost and the blame.
It’s simply not a smart business move.

Also I've found over the years if anyone wants to keep a same model of a common machine like a dell, hp, lenevo etc. you can generally find a quality refurb that's cheaper than getting a board replacement...way less of a headache many times.

I am grateful to all for sharing their valuable advice.

Youtube is a great resource. Experiment with search syntax.

Oldergeeks.com has "some" schematics here is an example. https://www.oldergeeks.com/downloads/file.php?id=4603
