Hello! recently got my new laptop Lenovo Yoga 720 15.6 GeForce GTX1050, Core i7-7700HQ, 16GB RAM, 512GB PCIe SSD, Active Pen, W10 Home

 

When i start the computer the laptop screen is black. When i plug a monitor to it i see the screen. then i go and check on what screens are detected in the nvidia settning, and i only find the external screen not the laptop screen. anyone else have this problem? do someone know what to do?

look at the keyboard, there should be a combination to switch from internal to external and back and activating both. 

 

Try out that key combo... waiting around 10 seconds after pushing it. 

 

If this doesn't change anything... RMA the Yoga due to being broken.

Main System:

Anghammarad : Asrock Taichi x570, AMD Ryzen 7 5800 @4900 MHz. 32 GB DDR4 3600, some NVME SSDs, Gainward Phoenix RTX 3070TI

 

System 2 "Igluna" AsRock Fatal1ty Z77 Pro, Core I5 3570k @4300, 16 GB Ram DDR3 2133, some SSD, and a 2 TB HDD each, Gainward Phantom 760GTX.

System 3 "Inskah" AsRock Fatal1ty Z77 Pro, Core I5 3570k @4300, 16 GB Ram DDR3 2133, some SSD, and a 2 TB HDD each, Gainward Phantom 760GTX.

 

On the Road: Acer Aspire 5 Model A515-51G-54FD, Intel Core i5 7200U, 8 GB DDR4 Ram, 120 GB SSD, 1 TB HDD, Intel CPU GFX and Nvidia MX 150, Full HD IPS display

 

Media System: Asrock ASRock Z87 Extreme4/TB4, Intel Core i7 4770S, 32 GB Ram DDR3 1600 ADATA XPG, 1 275 GB SSD, 1 240 gb ADATA SSD. IBM 5015 Megaraid, 4 Seagate Ironwolf 4TB HDD in raid 5, Gainward Phantom 560 GTX (the 560 will be replaced with one of the 760 due to better effeciency)

 

(Abit Fatal1ty FP9 IN SLI, C2Duo E8400, 6 GB Ram DDR2 800, far too less diskspace, Gainward Phantom 560 GTX broken need fixing)

 

Nostalgia: Amiga 1200, Tower Build, CPU/FPU/MMU 68EC020, 68030, 68882 @50 Mhz, 10 MByte ram (2 MB Chip, 8 MB Fast), Fast SCSI II, 2 CDRoms, 2 1 GB SCSI II IBM Harddrives, 512 MB Quantum Lightning HDD, self soldered Sync changer to attach VGA displays, WLAN
