...okay. She's never really been a computer person. Especially given she was frozen when she was a child. So, what's left for her to do, here?
"Does this place really pump sunlight all the way from the surface to the test chambers?"
“Yes. At least, the equipment described in that plan does exist, and it does seem to be bringing sunlight from the surface. And it happens that some of that light is used to grow the crops for the cafeteria you visited.”
(And the energy consumed by said equipment is much more than it would take to just illuminate the plants. But that sort of thing is just routine, now, and not worth mentioning.)
Teytis provides a link to the available information on Hard Light Bridges, which Chell can review on the screens if she wants to.
"Right, I guess." She continues looking. Eventually: "...why is there a room filled with robots that scream all the time."
Search.
“No documentation. It was built and named and if there's a purpose it wasn't recorded outside of GLaDOS's memory.”
Documents, logs, system activity reports, associates' photos, garbage, photos of garbage. There is very occasionally something of possible interest to be found.
Emancipation Grills — Design documents. Status: 92% operational (unauthorization hazard analysis)
Annexation Annex — Status: 10 green; 2 yellow; 0 red.
Very Large Particle Accelerator — Status: green. Data collection: lots of data!!!

…we present the Material Emancipation Grill, a device to assist in efficient, effective, and pain-free dentistry. Unhealthy teeth, portions thereof, or dental materials from previous work can be removed without the need for mechanical …
Status:
92% of grills are currently operational. Of the 6% nonoperational, 2% may compromise test protocols by allowing unauthorized objects to exit or enter a test chamber. All such test chambers are currently marked offline for maintenance and none are critical for emergency testing protocols.
Enough digging through the data turns up video, at which point it is obvious.
Bowling balls, whole bullets, blocks of ice, anvils, Weighted Storage Cubes, rocks, office chairs, …
All of these things are loaded into the particle accelerator, then fired at a remarkably unyielding target and the flying pieces recorded in excruciating detail. It looks like the original design merely consisted of dropping things down one of the salt-mine shafts, but it has since been improved by digging deeper and the addition of accelerator mechanisms.
