Which is the best way to prevent damage to the laptop / ac power jack when someone trips on the cable ?Dont ask me to buy a Mac since I already have one. This is for my new PC notebook.
Why don't you use an extension cord so it can lay flat on the ground?
Purchase a warranty that covers accidental damage. If you don't want to do that, arrange your cables where they can't be tripped on easily.
I would suggest using the velcro tye's you can get at any electronic store. Try tying off at the leg of your table. You can also use gaffing tape to tape it down to your floor. Gaffers tape usually doesn't leave a residue and is easily removed. Again, you can get it at Home Depot int he electronics section. Oh yeah, and be careful. :o)
