Display doesn't show up after removing intel display into BIOS?

The Lenovo Y40-70 has 2 video card, 1 internal radeon include in the processor and and external one R200 series.

To prevent windows of using the internal one, i deactivated the it.

But now on boot, nothing is displayed and windows doesn’t finish to boot.

Based on this i cannot go back into BIOS to try to fix this.

ANY IDEA how to solve this issue?

Thanks,

Hi,

If you meant a Y40-50 then try a power refresh and check if this allows you back into BIOS. Normally a power refresh restores the BIOS to its factory default settings. If it works then any other user definable settings that you have altered to suit your particular requirements will have to be changed back to what you had.

Turn off the laptop if on and remove the charger if connected.

Remove the back cover from the laptop and then remove the battery from the laptop.

Press and hold the laptop’s Power On button for a full 30 seconds and then release.

Reinsert the battery into the laptop, replace the cover, reconnect the charger and turn on the laptop.

Here’s the hardware maintenance manual for the laptop. This shows how to remove the battery

I tried your recommendation but still the same.

The fan start spinning but the display remains black...

My model is y40-70.

Any other recommendations?

@moopy

Maybe try resetting the BIOS "blind"

Get into BIOS on startup (I realize that there is no screen) and then press Fn + F9, then Fn + F10 to save the changes, then Y, then Enter

Allow a bit of time ~30 seconds to allow the changes to be made as it isn't totally instantaneous before pressing Fn + F10 and continuing on with the procedure

Fn+F9 = resets to factory defaults

Fn+ F10 = save the changes

Y = Yes

Enter = Accept

Note: not sure if there is a Y or Enter after Fn + F9 in the procedure but if it doesn't restart after the Fn + F10 then Enter key, then perhaps there is
