Windows 7 - Plugged In, Not Charging

I have a peculiar problem with my laptop, The battery indicator shows, "Plugged in, Not Charging" even though the power supply is there and the percentage remains at a particular level. Please help me in this regard.

Hello ankur, welcome to the forum.

Should this not work it is a good sign that the battery is almost at the end of its life

Note that this may also be configurable in the BIOS - some laptops (especially newer models in the last few years) are configured to not recharge the battery if you haven't discharged it after plugging the machine in <n> times. This is why you need to run your battery down to less than 50% and see if it starts recharging again - simply plugging in your laptop all the time is actually detrimental to battery life/health.

Hi ankur, have a look at this thread Stupid Stupid Laptop Battery pay particular attention to the posts by BarMan58 He gives good info on the care and charge/discharge cycles for the battery to last a long time

I want to add one more thing that my laptop is just 10 months old, I just checked the BIOS Setup, BIOS Version and EC version are different. I think they need to be same. Can someone clarify me on this? I used all the solutions on the Google regarding this problem but the problem still persists. It again shows this notification after charging to 99%.

If your laptop is just 10 months old you can get this fixed under the Guarantee that is the best option you can have

But see I want to know about BIOS, does BIOS version and EC version need to be the same?

Could you clarify what you mean please? BIOS setup, BIOS Version EC Version.
