Ah, fond memories of reading the caller id data from a pbx serial port! I actually made a nice little phone log application out of it, tracking the call activity of a dozen or so collectors. I gave it away and let the owner eventually make some money from it.
When I try to tilt the angle of view on my notebook, it throws fit and lands on a BSOD, consistently.
I was unsure how this was happening. Just to observe the behaviour, I left my notebook intact on my desk without moving a bit for 2 weeks. There was no problem.
When I lifted the notebook, the slight movement on the lid, threw the notebook to crash, immediately.
I thought maybe the pressure at the bottom of the notebook(when I left) is crushing the circuitry or an HDD controller cable, something like that. But it's not.
It's confirmed with the final experiment: On the desk, without lifting the notebook, just pushed the lid back a bit. It lands right into this screen.
And far worse - If I pushed it further, the whole screen became a dump of noisy horizontal lines flickering like an ECG gone wild.
It's a PITA to think about giving the machine to the service centre..taking backups etc.
Well notebooks must have a sensor that detects lid position, as most include a feature that activates sleep mode when lid is closed. So maybe that sensor is causing problems.
Perhaps on that note, you can try disabling any "sleep mode" features and see if it still happens? I get that you are not fully closing the lid, but still that sensor could be triggering some kind of check which is problematic.
No idea, and I would have thought something like that is more likely, but I could have sworn my old Dell laptop would go to sleep much before the lid was fully closed... but human memory can be volatile, so who knows what I remember
When you try to move the lid angle, you are flexing the keyboard case around the hinge. That is putting pressure on the PCB which mounts to it and that loosens something that has come "unstuck" - could be a solder joint, could be a connector, could be a flexi that flexed too much. If it's out of warranty then it's worth opening it up and checking ram and processor seating, having a look at flexi cables and how "straight" they go into connectors, that kind of thing. If it's in warranty, then it's "backup and send to the service center" time - these things don't get better on their own, and they generally need some serious soldering skills (or a new MB which is the modern equivalent).

You know, even if it is under warranty, and the memory is user-accessible, I would try removing and resetting the memory just to be sure it isn't just a loose stick of memory. Would suck to send it all the way back to the service center just to have them diagnose a loose memory stick.
On another thought, it could also be chaffed/loose wiring/harness. There are a lot of devices located around the screen (besides the screen itself), such as cameras, microphones, indicator lights and multitouch sensors. If you happen to have the lid open anyhow, look for areas where the wire insulation may have worn through by rubbing together or on something. Some electrical tape and/or heat shrink tubing may be all that's needed to solve the issue, saving you from having to buy a new laptop.
