Described previously.

Now, most ethernet NICs will tell you that and not the OS. A light exists on an NIC and on the router. When an NIC computer talks to the router computer, then lights on both units illuminate to report a good conversation - only to you. What do those lights report?

^I didn't want to say, but sir, your to-the-point posts are, apparently, not of the level which OP could get. (It's almost apparent till now, no offence to OP). Situation demands for a layman standard.

Spoiler

PS: You once helped me years back in a similar issue , and I was pretty sure of your kicking in, when this thread started.

Described ethenet lights are equivalent to a car's "Check Engine" or "Temperature" light. And usually described in the instruction manual written for consumers.

"My car won't work." "Is the check engine light on?" A typical answer is usually humor to car mechanics.

Hi,
Can a laptop USB be fixed withing replacing motherboard?
the thing is my usb works.I mean only 1 port works out of 4. And sometimes others works for a minute then says usb not recognized.
I assume that it is getting low power hence it says that error.
So my Q is can we fix the usb port problem without replacing MoBo?

Can a laptop USB be fixed withing replacing motherboard?

You have no reason to suspect low power. Reasons why the USB ports are intermittent are many. OS has a system (event) log. That information provided to others means a better informed reply can exist.

Laptop USB hardware is typically repaired by replacing the laptop's motherboard. Some laptops have a peripheral card slot. A peripheral card that is a USB interface might be installed. Or spend bigger bucks for a USB hub that connects via the ethernet port.

Your questions and 'later discovered' symptoms are why better computer manufacturers provide comprehensive hardware diagnostics for free. Sometimes, things that appear to be good are defective. And sometimes things that appear defective are good. All your USB ports may be defective even though you see one working.

If your computer did not provide those diagnostics, then you have learned of one item that separates better laptops from inferior ones. Many if not all of your questions could have been answered by that diagnostic.

How to avert future damage and why that laptop is probably damaged also was summarized.

At this point, you are probably viewing a new computer. Learn from what happened to this one.
