Hi there, Bahavathi     -

 

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

 

You can also start by flushing out all static, remove battery and AC adaptor and hold down power button for about 15 seconds.

 

Unplugged the speaker's wire, which goes to motherboard (placed under palm rest) and plugged it back. Please go through this HMM for better understanding.

 

Update us how it goes.

 

 

 

 

 

Regards,
