The computer was running in a docking station and when the person came back to it, it was off. No charging lights or any functions at all. Does this have a fuse of some type internally? I tried putting a battery from another unit in and it did not make a difference.

I connect to an unpainted surface, of an empty open desktop computer case. (I don't feel an Anti-Static Mat is warranted, and can explain)
You can set a large metal serving tray (Unpainted), on the table you're working on, and connect to it. Or perhaps a large metal knickknack. (Unpainted)
You can't discharge Static by touching the metal frame, of the laptop. Doesn't work that way. (ZZZZZzzzzap! Goodbye computer )
C) Use a multi-compartment container for the various screws you will remove. Label each compartment for the area the screw/s come out of. SOME screws look VERY similar to other screws! Advise do NOT mix them up.
D) Take photos, or use a video cam; if available. Use good lighting. Make notes, and/or drawings if you wish.
It's nice to have a Personal record, as well as a Service Manual, and pictorial information. It's nicer to have YOUR method YOU used, along with the above.

Put everything back just LIKE it came out. Don't pinch any cables.
Torrential rain storm left out in it running? I'm sorry to say there is only one thing you can do for this laptop. "Do not turn it on at all again" Take the battery out of it and take it completely apart and use a blow dryer and dry everything out. "Everything" you may already be to late. Board may be shorted out and fried I hate to say it. So take it apart piece by piece and top case and bottom case and dry it completely out. So that there is nothing wet or moisture is dissipated and gone. That is the only thing you can do to salvage this machine other than a new board, rain and left running in the rain is pretty easy to figure out that you may have ruined your computer leaving it running in the rain. "Lets hope this will work for you" I would be pleased to know if it did solve this matter drying it completely out." Do not power it up again until this is finished. John
