Hi there, Shruthi  -

 

Thank you for writing in to the Lenovo Forum - happy to have you here today.

 

Sounds like a defective battery to me but first I l try to investigate to fix the problem.

Go to your power management settings (control panel > power options) 
change the default behaviour when you close the lid of the laptop to "shut down" (i'm sure it's set on sleep, or hibernate)
check out what the power button is set to do... it might be set to hibernate or sleep instead of shutting down.


Take your time, go through the advanced menu looking for power settings that indicate this laptop might be hibernating or sleeping rather than powering down.

 

You could also try a "hard reset" for the PSU:

 

Note: To perform a hard reset, unplug the AC power adapter and remove the battery, and then press and hold down the Power button for about 6 seconds. This will drain any residual charge in the capacitors and reset the power management controls to their default condition.

 

Update us how it goes.

 

 

 

 

 

 

Regards,

I agree with Sashi,  you should try some trouble shooting to see if it is the battery, or the AC Adapter that is the source of the problem.

 

My two cents - most notebook batteries (no matter who built them - HP, Dell, Lenovo, etc) use Lithium Ion cells, and they are managed by embedded electronics (inside the battery pack) that will control the rate of charge / discharge

based on the individual internal power cell condition.  In my experience most batteries do not have more than a year to a year and one half of lifespan, and can be even shorter if charging cycles are closer together.

 

If your battery is not under warranty, make sure you purchase a replacement from Lenovo, or match the specifications of your current battery exactly when buying elsewhere, you can find a listing of batteries and other parts in your computers maintenance manual.

 

installing the wrong battery can lead to disastrous consequences...
