Re: HP Envy 17T Issue
I'm not familiar with that computer at all but wonder if there is an interlock on one of the covers that's purpose is to prevent the computer from starting when opened. If you put it back together does it work then?
If it works when you put it back together then there may be a microswitch imbedded somewhere that depends on a cover to be put in place in order for the switch to be closed. If you could figure out where that switch is and tape it closed, you may be able to get it to start with the computer taken apart. This is just a guess since, as I said, I have no experience with that actual laptop.
