I think you are one of those guys who puts dying hard disk drives in industrial freezers.... ;)

Yes, yes, I did and still could not get my data out :( . It was a HD. Kill by my 12 yr old left in the car for 24 hr during a hot hot hot summer. The hd died in the house, and I mouned over it for half a day, and carefully wrapped in a piece of cloth and very gently landed it in the frige for couple of hour....took it out, no sign of life.

Good to hear a 67% success rate. Thanks. I have a whooping 0 % success rate. I was curious about the reason behind this. I think it is because the platters are hot and expanded during use and 'jammed' (whatever it mean :) ), so lower the temp, theoretically may be able to unjam it. I am NOT sure about of temperature with electronic failing.

Any mechanical damage would result in an unrecoverable HDD (in that case if you really need to get your data back there are companies that will do it for you, but prepare to sell at least a kidney :D)
Cold lowers electronic noise, thus maximizing the SNR and sometimes making possible to get a useful signal out of a dying chip. ;)

I tried my 770 again this morning and still same result. I'm not surprised since it only got a few hours of sunlight. As someone said before, the 770 has a sealed enclosure so it would be smarter if I take it out carefully and let separate parts dry...

Yes, that should help... but did you just say you left your 770 in the sun? :confused:
That's bad, first of all because the excessive heat created by the direct sunlight exposure can seriously damage the most delicate parts of your device (expecially the screen :eek:) and second because, given the sealed enclosure, the excess of vapour is even more dangerous than water itself because it can easily infiltrate in smaller places...
Go ahead, disassemble your 770, but let it dry at room temperature and avoid direct sunlight... and let's hope all the abuses didn't kill the tablet ;)

I left it by the window in an AC'ed room. I will put it back and will have to disassemble it since the water in the screen isn't getting any less. I made the biggest mistakes. I learned one lesson though; never use the 770 in the toilet!

Seriously, the oven trick might wok:

If your NIT stays TURNED OFF, and you remove the battery, you cannot damage the screen or other parts by leaving it in the sun all day. This wil help to dry out the moisture. I work in an engineering R&D lab and it is my job to expose various electronic circuits to their maximum temperture limits.

Batteries à la vapeur.

Yummy :P

I was assuming that, being the digitizer made of a plastic layer glued over a glass one, putting that in direct sunlight on a hot summer day, let say six hours from 11am to 5pm (it should be the hottest part of the day if you didn't plan a "special evening" :D), could result in an expansion of the "fluid" in between the 2 surfaces, putting pressure on the weakest of the two layers (I don't think the "chamber" is vented) possibly causing warp or glue failure...
Sure, I trust what you say and I'm probably (ok, completely :D) wrong, but given the fact that the poor 770 recently visited a not so nice place I wouldn't risk overheating too :D

By the way, what is the typical temperature range for a commercial grade LCD+digitizer assembly?
