Q. What all parts can be repaired or replaced in a laptop's motherboard?

[DaveLembke]

Answer:

Everything but the LCD or LED display can be serviced. Displays are throw away replacements that you replace with another good display.

Motherboards and other electronics are serviceable, however...

Depends on many factors:

- If you have the tools to safely remove and replace surface mount components or replace traces.
- If you have the skills to troubleshoot and fix the problem.
- If the parts are available.
- BUT mainly... if its worth even going through all the trouble to invest time and money into fixing it instead of buying a replacement that would likely be newer and better.

DaveLembke,
That is a correct answer. True.
However, the cost of finding a bad component-
is measured in hours, not minutes.

One could assume if the OP did not now the answer to his question, then he had no idea of how much work is involved.

Wait... here is a super simple answer. Does the thing still boot from a CD? If so, make a CD to flash the BIOS and see if that fix the problem. If nit doesn't, just replace the motherboard.

The above if from another site in answer to the question:

How can I repair my laptop motherboard?

What parts can be replaced on a laptop motherboard - Answer is pretty much everything.

But the question is what parts can I I replace or what parts are economically viable to replace - Answer to that is "not much" - The only common part to be replaced on a motherboard is something like the power jack as they often get broken and are fairly easy to replace, similarly you can also replace most other ports.  If you are referring to any components on the board (ICs.etc), while they are technically possible to replace it is very rarely worth doing this versus just replacing the board.
