On some keyboards, the SysRq key may be labelled 'Print Screen' or 'Prt Scr' or 'prt sc' or something similar but should still function.
It may be the lock up will prevent any keyboard interaction. One test of keyboard function when locked is to toggle the caps lock or num lock keys and see if the LEDs toggle (if the laptop has LEDs).
If the keyboard is unresponsive when the machine locks then the options are reduced. Random/intermittent hardware faults are hard to pin down - sometimes the systematic replacement of parts is effective but with a laptop, usually only the memory and disk are realistic to swap.
Can you see a pattern to the incidents (e.g. opening multiple tabs in a browser or running certain applications) ?
You could try booting from the install disk/stick and running the memtest option from there. This will exercise the CPU and memory and may find something if you run it long enough.
You may consider installing something like gsmartcontrol which allows you to see the health stats of your disk(s) if they are SMART capable. If the disk is failing, SMART may show something.
Perhaps try operating in a lower screen resolution.
