Hit the computer with a hammer.

You check your inventory. No hammer - but you could try hitting it with something else. Tends to do the trick. In your inventory, you have: Your trusty magnifying glass. Your keyring, including the hotel master key you were given earlier. The oily note. The shipping/receiving clipboard. The employee punch cards for GH and CS. In your pocket, you have the bloody knife. In your weapon slot, you have the recycling poster.
