Use old lapdock as a tablet dock?

[Shikyo]

Backstory:
I have a lapdock from my old Atrix that had the LCD go out on it. I was wondering if it would be possible to just use it as a battery, keyboard, and usb hub for my Nexus 7. I took apart the dock to access the micro usb plug to go into my Nexus 7 but have no use for the HDMI. However the lapdock is enabled when a device is plugged into the hdmi.

Question:
How do I enable the lapdock without anything plugged into the HDMI.

Can you get any pictures? It would be helpful.

If you the cables out, have you tried plugging the microusb into the nexus 7 and the microHDMI into the phone(to power it on) to test whether the nexus 7 even detects the keyboard, mouse, charger of the dock?

I Don't have any devices with micro HDMI anymore (Atrix went to craigslist). I ordered an adapter for regular USB but from China so who knows when I'll see that.

The nexus 7 doesn't support HDMI out at all. Google confirmed that... What you could do is make some like of dummy or I read somewhere to short some wires... Read before you do anything though...

I know the Nexus 7 doesn't support HDMI. Thats why I'm here asking if anyone knows how to short the HDMI. Having trouble finding anything on it.

sorry for digging and old thread but until now im using the lapdock as otg hub, a keyboard and track pad. i have to remove the lcd screen since i have no use for it. very useful indeed up to now 2018. i usually use this setup playing pubg mobile. i dont a tablet but probably it also works

if you have a broken lapdock lcd, then you can have mine for free. except you shoulder the shipping of course
