I think it's always a good idea to carry fresh water on vacations...especially surf trips! you never know what the tap water will do to you :)
Way to go, you got your surf link up...!
Here is my take on the laptop lubrication. You have a few options here. I would stay away from WD40. It is flammable (lpatops tend to get hot). You could use knife oil. I am not sure of the exact name but it is used on a wetstone to sharpen knives. Another options is getting a drop of motor oil. Either of these on the hinges should help. Of course, you could get another (cheap) laptop when you go back to Thailand. I hear there is a huge market for knock-off computers that work just as well (of course this is a rumor I have heard). Good Luck

My computer is working great, I do not need a new one and it is not broken, I am try to learn the best way to lubricate the hinge on the screen. I do not believe that Motor Oil is the solution as best I can learn it gums up the works. The knife oil sounds like an option and maybe it is possible to buy in Taiwan. There is surely some solution that would be obviously perfect, and not questionable. I suppose I should write Hewlett Packard and see what they say.
I was not able to click on the Prudenttravel.com link so I am trying to see why the link was not working. I am still learning how to use the comments section.
Aagh, people have to know some html it seem to make a link work...
So hopefully I can get a clickable links this time.
I would stay away from oil of any kind as oils can attack the plastic. I would use silicone spray on a q-tip, or silcone grease (dielectric grease). Don't overdo it, one can of silicone spray would lube every laptop in asia...
