Thinkpad T470 Refresh Rate

Hi, the monitor of my notebook, during the switching from the first battery to second battery (power bridge technology), goes blank for 1/2 seconds because the refresh rate of monitor changes from 60 Hz to 48 Hz. I tried to set the refresh rate  on 60 Hz but the problem persists. Thanks in advance.

Re: Thinkpad T470 Refresh Rate

To do this: Go to the control panel, and look for “energy settings”.  Go to the energy plan/setup in use, and click on the “change plan options” link. Go to “advanced energy configuration”, and then go to Intel Graphics Settings > Intel Graphics Power Plan; have both plans (with battery or plugged in) be “Maximum performance”. This will result in the refresh rate remaining at 60hz when one connects or disconnects the A/C adaptor, without the annoying black screen which lasts a second or two.

 

Note that doing this will reduce battery life.
