I got pissed of with Lenovo thinkpad's, last 2 broke hinges
I have a toughbook tablet thing but prefer a laptop
Work buys a laptop, it gets used at home for year or so, then goes to work when it gets marked then broken, meh.
There already a replacement machine waiting in the wings...
rip it out & put a decent lighting controller it, (but nobodys make anything to compete with it ?)
take the cover off & walk test it (they go opaque with age
swap sensor around to see it the fault follows
work the pots back & forth to see if the lux sense are at a working level
swap a sensor with a new one
fault finding is 2 man job after hours, it cheap to put the lights on timer
the recommenced minimum height is 3m ?
having to stand on a leaded bay was not uncommon
however-
working on this can't ready be done safety off a ladder?
an unsed TS700 with mains on the pcb, vintage....
