So it looks like a pretty nice 286 laptop - I particularly like the keyboard. If it gives you a single beep, it seems to be booting. Try fiddling with those sliders next to the screen. Failing that, look into an external monitor.
That MPU-IPC though - that box combined with the card it's plugged into is a MIDI interface, or rather THE MIDI interface. If you look into vintage MIDI stuff you'll read about "MPU-401 compatible" to a greater or lesser degree. This is the thing they are compatible with. People are making new ISA cards today to emulate the functionality of this beauty. You use it to hook up MIDI devices to your PC- gamers use things like Roland MT-32 and SC-55 modules, musicians use any number of devices.
Even in its current bashed-up state, it's almost certainly worth significantly more than the laptop it's in. Whatever you do, don't separate the MPU-IPC from the card it's connected to.
