It has gotten hotter at my house than it did at Free Geek yesterday, and I wasn't using it intensively at the time. I should have mentioned that I have never installed the proprietary nVidia drivers; just using the Ubuntu flavor of nouveau. >> When I got home I restarted the computer and it proceeded normally. >> However, my computer life was about to enter hell.

It's a Phaser 7400DN, enormous laser for printing on 12 by 18 inch card stock. I'll have to deal with it later. >> I continued with other things at he computer, and as I was doing so I >> knocked a liter of soda directly into the keyboard. >OUCH!

It was diet soda, so no sugar, but it still had a lot of stuff in it that is hard to pronounce. >If you don't know how to remove the keyboard, check the user's >manual that should have come with the laptop.

All I got was a single sheet of paper with cursory instructions and links to Ubuntu help sites (they ship it with straight Ubuntu Unity, although I nuked it and installed Xubuntu instead). I might be able to get something from Sager, since it's the same as their NP9380, but I haven't checked with them yet. >Yeah, this looks like the soda dried inside the keyboard.

Then I'll try cleaning the old keyboard, but I'll have the replacement on hand in cse I need it. I'll be at OSCON until Thursday, by which time the replacement should be here. Thanks for the ideas. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
