Laptop with external gpu problem

[goldenguyfollder22]

Hello. I have laptop 'toshiba satellite l300 1a2' and im trying to connect to it 'gtx 1060 3gb' using this riser: https/s.click.aliexpress.com/e/bniiqC6W

My laptop just doesnt boot when i turn on power supply for gpu. I also tryed using different gpu (dont remember its name, will remember later if needed) but result is the same. When i turn on laptop its cpu fan start spinning and stops after 3 seconds, screen is black, keyboard and mouse/touchpad doesnt seems to be powered. Screen connected to gpu doesnt shows anything too. I can make a video if that will help.

I also tryed turning on gpu when laptop in sleep mode, but its not getting visible in device manager.

Any idea? 🙁

I read more about this and i think i have a clue. How do i unlock my bios? Or can someone do it for me, if its not hard. My bios: https/cdgenp01.csd.toshiba.com/content/support/downloads/slb8v220.exe

an external power supply is required too. To power your GPU L. Do you use any power supply.

Yes, i do.

I think your current riser cable isn't compatible with your laptop.
Try out different riser cables

Nvm. How do i unlock bios andvanced settings?

Okey, i hacked bios. Took a while 🙁. I enabeled hop plug for pci express port, and now laptop see gpu when i connect it while laprop is in sleep mode! I installed nvidia geforce experience and it installed drivers for gtx 750, but device manager shows error 43. Reboot and reinstalling doesnt fixed it. Any idea? Also, maybe i need to change something in bios to make laptop boot with gpu enabled, there is many settings now.
