Re: back light not working in lenovo ideapad flex 4 1470

Hi there, Yudhi           -

 

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

 

Could be a loose connection inside the laptop. However before visiting the service centre kindly perform the below steps:

 

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

 

Also, Go through this HMM & re-seat the keyboard.

 

For further assistance,I would suggest you visit the nearest Lenovo service centres for assistance. Schedule a Call-back for faster support.

 

Update us how it goes.

 

 

 

 

Regards,
