Charging issue

[Aashna1]

My battery drains fast from the beginning. After 2 yrs now sometimes it does not charge when plugged in. Once it took whole night to charge. I tried removing battering and pressing power button for 10 sec then plugged in and uninstall battery driver. It worked 3-4 times. But now it is not working and the charger is draining when plugged in.

Hi

Then the Power Supply has failed if it cannot support the Battery and/or the LapTop is my guess.

OR maybe I misunderstand the situation.

This will not work for everyone, but you may be lucky?
NOTE: Be sure the battery is installed in the computer and it has sufficient power before continuing. Due to the design of the Embedded Controller/Keyboard Controller, the power supply must be disconnected and the computer must be powered with battery power to reset the Embedded Controller/Keyboard Controller.

Unplug the AC power from the computer.
Press and hold the power button for more than 12 seconds.
Release the power button (after at least 12 seconds).
The computer will power on and should boot normally after releasing the power button.
Re-connect the AC power to the computer.

NOTE: In case the battery is not charging after performing the steps to reset the Embedded Controller, unplug and re-plug in the AC power again.
