What's blinking? The monitor backlight? Chances are it's just PWM, it may be possible to change in BIOS. You can also put a decently-sized inductor in series with the PWM wire going to the backlight to turn it into a more linear constant-current, along with a "freewheel" diode in there to cut off the nasties, perhaps a capacitor too. Pic related. Choosing the inductor is a matter of checking how much power the backlight uses and at what current, calculating the energy used by the backlight in a single PWM cycle at maximum, then use that current and energy value to calculate how large an inductor would have to be to store that. With a large enough capacitor there you can probably go a fair bit below that value, but you might also get ringing.
Feel like soldering into your laptop?
