What kind of repairs/damages are more costly?

I'm not talking about replacing an LCD (which I know is very costly), but for example,
a. Replacing the motherboard
b. Replacing the HDD
c. Plastic casing damage around the screen or around the keyboard

Which of these are more costly? I have no clue.

 

Motherboard would be next costly after LCD. Plastic casing damage could be next costly after motherboard. HDD is easy to change.

 

Depends on the model, if you do it yourself the LCD can be rather cheap. Motherboards are ALWAYS expensive.

 

Why is plastic casing so costly?
(I don't mean self-fixing, I mean in warranty fix)

 

Same reason as MB's being so costly: they are specific to a manufacturer and a certain product (model) line.

I had thought motherboard was expensive, however, it was just strange to me that when I sent my machine for repair of some issue, the first step they took was to replace the motherboard; it didn't solve the problem, so the next time, they replaced the HDD (or did something about the HDD). I would think motherboard should come as a later step.

So plastic casing is expensive because they have limited resources?

 

It is easier to change the MB and test it later and reuse it. (You don't think you got a new MB, did you )?

Limited resources in the sense that they only estimate so many 'shells' as needed for the life-cycle of the product and consequently each one is priced accordingly.

Cheers!

 

I see, got your point. (MB means Mac Book? I've never had one )

So under what circumstance does it get so expensive that they stop fixing your machine and instead give you a replacement?

 

MB=Mother Board.

MacBooks are not in my vocabulary.

j/k


Those circumstances are when you still have warranty and they don't have parts readily available.

Cheers!

 

:laugh: MB!
Yes, I did get a new MB, unless they lied on the the report sheet. It said MB had been replaced. :yes: They said because the (defective) ethernet socket was soldered on the MB. I had thought ethernet socket should be one of the easiest and cheapest fix?

 

Often times, if it's an older laptop, a lot of people will sell those for parts instead of the whole. If that's the case, plastic parts are cheap.

With an LCD that's used, it's a toss up, especially if it's picky, and people tend to trump up the actual quality and condition of (I'm picky, and I've dealt with replacing 2 LCD screens).
Motherboards may have a more tolerable level of less than pristine, but you might run into more problems later with weakened solder joints, especially if they were rough on the system.

I recall the LCD actually being more expensive, on an older model. Brand new however, motherboards are more expensive as they are more proprietary.

 

Motherboard>GPU (if removable)>CPU (if fast)>LCD>Plastics (complete chassis)>battery (if original).

That's what I think

 

A lot of the time it will depend on the model, and whether it is proprietory/proprietory socket. But generally, I think it would go motherboard, GPU (could be more than the motherboard depending on the model, you have to factor in whether it's MXM or proprietory), LCD (again, could be either more or less, depending on what resolution and what brand), plastic casing (depends on what part of the notebook and whether it's an old notebook or not).

CPU pretty much spans across all of that, as you have stuff like the T6600, which can be had for $100 or so, then there's the QX9300 which costs in excess of the $500.

 

Ethernet is a function of a chip on the motherboard. It's all soldered in and if it really is faulty then the MB needs to be replaced.

 

What? Wrong topic?
