Re: [Thinkpad] New Thread ~ 701 & 760 ThinkPad

omg ! ~ it actually worked for about 3 minutes until 95 completely
froze !!! but it stayed on "frozen for a good 10 minutes until it shut
off ~ I think it fried. We first fired it up and then submerged it.
What a good belly laugh we got over it ~ some of us are still chuckling.
My brother is clear coating some components right now, (this was his idea
not mines) but 3 coats should seal the leads ~ then we're going to rubber
seal all the connectors then finish it off with sealer around the cracks and
ports.
.
The keyboard didn't from the first second it went under water so that's getting
plastic bagged. The only thing left for our deep sea (ok pool) underwater
experiment (7 foot) is the hard drive ~ lol.. That thing needs air !!! I think
the reason it lasted as long as it did was because there was still a pocket of air
inside the laptop the hard drive could use, but as soon as the water got in, it
probably sucked the water like a vacuum pump. The top lid got really hot even
under
water, I think the lcd started shorting out around the edges. Bet you it ran
cool though ~ lol

You hear of people getting married underwater ~ hey why not play solitaire,
surf the web and check e mails underwater I'm still laughing !!! :
)

Ok, so much for that !
