《不义联盟2》毒藤女新预告 动画妩媚招式凌厉
百度 我们还会继续破纪录的。
Following Error occured 2 day's ago on several SurfaceHub Gen1 in our company:
SurfaceHub error: secure boot violation invalid signature detected. Check secure boot policy in setup.
Solution could be to disable Secure Boot and other UEFI details.
But following process to enter UEFI / Bios is not working at all:
- Shut down the Surface Hub completely.
- Press and hold the volume up button on the side of the device.
- While holding the volume up button, press and release the power button.
- Continue holding the volume up button until the Surface logo appears.
- The device should now boot into the UEFI (BIOS) settings menu.
We did test with several different SurfaceHub devices and all kind of pressing and holding these buttons, even with external cabled Keyboard. Not able to enter UEFI.
Does anybody have same issue?
Know in detail how to enter UEFI at Surface Hub Generation 1.
thx for any hints Bruno
