Hello , from a few days ago suddenly my laptop ethernet port is not detecting the ethernet cable, i have checked the device manager ethernet adapter settings there are no yellow/red markers and the drivers are also up to date.So how can i make the ethernet port working again.
Ethernet port not working.
Just try reinstalling the drivers again and/or you can also try to check it with a live copy of Linux like Ubuntu. Also try changing operation mode to 10 Mbps half duplex, full duplex etc. And does the Ethernet LEDs glow when you plug the cable? If you can confirm all these, we can be fairly sure that there is a problem with the Ethernet chip.
Does the LEDs glow before Windows loads? That is in BIOS? If it does not, then we are sure that the chip is gone. In that case, claim warranty if the laptop is still under it or buy an USB LAN card.
As for re-installing drivers, search Google for "laptop model name" drivers and you should get appropriate links. Do let us know of you face any difficulties.

my problem is a little different..
when i plug in ethernet cable it does not glows .. but when i disable and renable ethenet adapter the light glows for a second and then switches off ..

I have installed/re-installed the drivers ,still the ethernet port is not detecting the cable and displaying message (in windows network diagnostics) as "cable not connected".Can the ethernet port be easily repaired? Can anyone post what causes the ethernet port to malfunction?

As I said, a thunderstorm is the worst enemy to an Ethernet chip. But since you told us that the cable is detected when you push up the cable, I would suspect loose connections. Either the port pins are corroded with oxides/pins damaged or the pins of the port has lost contacted with the motherboard soldering joints. Show the problem to a laptop repair technician and he/she should fix it in no time.
In your case, the Ethernet chip is very much alive and working since you mentioned that the cable is detected when you push it or such. So that is good news for you.
Even at the worst case of ripped of solder joints, it should be cheap to get it repaired.

+10, my previous PC's jack + my modem's jack got burnt in a single thunderstorm
