Take the cover apart and check that the gimble is free to move. the gimble is the multi directional joint which alows the laser to hang vertically.

To check calibration, take it into a hilti center. they'll check it for you. Otherwise, set it on a countertop or table. Mark its level at a distance of 15 feet, rotate it 90 degrees, and check to see if the marks jive. If the dont a calibration will cost $60 plus shipping. call 800 879 8000.

Why is the Green light not blinking?

Do a peg test, if the unit is leveling and accurate, then it's just the green diode has malfunctioned, dont worry about it, it happens.
If the peg test fails, then either the keypad board has failed, or a motor may be jammed. Or possibly the laydown switch has is stuck, and the laser things it's perminatly in vertical mode, and wont level. Take it to a laser/survey shop as the front label will have to be replaced just to open it, to diagnose.

Vertical laser is no longer working.

Had the same problem. Actually had vertical beam and one horizontal beam not working. I put the laser in the freezer for about 30 minutes, took it out and all the beams work. Prior to that I cleaned all the battery contacts and of course installed fresh batteries all to no avail. I have no idea freezing it worked but it did. Of course freezing it would cause condensation to form on the inside of the instrument but why that would make the laser work is not known. I hope it works for you.

Spectra precision laser turns on but doesn't spin

Its usually a simple ''belt'' that rely the head to a motor. Open it, replace it and if its damaged, go to your nearest electronic parts broker, he will sell you a tape deck belt for it. Sometimes rubberband might be okay too...
