When i connect charger to laptop the power button and charger light starts blinking

Hi ZMR 1986,

Thank you for writing to Dell Community Forum.

* Are you able to boot into windows normally?

* Please try to boot into BIOS and check what is the status of the battery / adapter listed.

* Please update the BIOS to the latest available version from our Dell Support Site.

* Can we check with an alternate adapter?

Please private message us the service tag of the system along with your email id.

(Note: please don't mention the service tag or email id on the public forum as it contains your personal information).

My laptop could not turn on... Nothing is displayed on the screen

Unplug the adapter from the system -- does the LED stay on solid?  If so, it's OK.

Plug into the system with the battery removed.  If the light stays on solid and the system will start up, the battery is faulty -- replace it.

If the adapter is OK (step 1) and starts blinking when connected to the system even without the battery installed, the mainboard is faulty and will need to be replaced.

It's almost certainly a bad mainboard.

Could not start if i battery remove the battery...

I removed the battery and plug the charger to laptop. When I press the power button laptop could not start

And the charger light getting dim..

Can u plz let me know how this can be solved

The mainboard needs to be replaced.

The part itself ranges between $120-200 depending on whether you have Intel or ATI video.  If you have to pay a shop to replace the board, add another $100 or so in labor - at which point it may make more sense to replace the system, particularly given the age of the N5010.

Plz let me know what is the price of dell inspiron battery & charger..

An adapter should run $30-50;  a battery, $100-120.
