stopped turning on

my smok procolor will not turn on. if i take the batteries out and put them back in it will show the smok logo and then cut right back off. if i plug into the computer it shows its charging but thats all. i have checked the batteris and tank on a different vape and both work someone please help

I woke up yesterday and it wouldn't turn on. Left it alone for several hours and it came back on, now it won't turn on again this morning. My tank leaked ejuice in it maybe a month or two ago but was still working fine aside from a single drop of liquid showing inside the display. Warranty...
