Narrative:

While departing runway 1 at teb in IMC; we were on the teb departure turing left at 1500 ft to our level off altitude of 2000 ft; with the autoplt on and using VNAV and navigation modes. Immediately after reaching 1500 ft. My flight director was somehow deactivated and therefore the autoplt did not comply with leveling off at 2000 ft. I kicked off autoplt; hand flew aircraft as it had already gone through 2000 ft. By the time I recovered we had reached approximately 2600 ft MSL and I quickly descended back down to 2000 ft. Teb departure said aircraft X; you were supposed to stay at 2000 ft. He gave us a new frequency and no other conversation happened regarding the slight altitude deviation. I was not asked to copy down a phone number and expect no further action regarding this occurrence.

Narrative: WHILE DEPARTING RWY 1 AT TEB IN IMC; WE WERE ON THE TEB DEP TURING L AT 1500 FT TO OUR LEVEL OFF ALT OF 2000 FT; WITH THE AUTOPLT ON AND USING VNAV AND NAV MODES.

I KICKED OFF AUTOPLT; HAND FLEW ACFT AS IT HAD ALREADY GONE THROUGH 2000 FT. BY THE TIME I RECOVERED WE HAD REACHED APPROX 2600 FT MSL AND I QUICKLY DSNDED BACK DOWN TO 2000 FT. TEB DEP SAID ACFT X; YOU WERE SUPPOSED TO STAY AT 2000 FT. HE GAVE US A NEW FREQUENCY AND NO OTHER CONVERSATION HAPPENED REGARDING THE SLIGHT ALT DEV.
