A while ago I decided to fix something under my HP tc1100 hood. I had bad idea: I loaded the default BIOS settings. Turning the tablet on I had a bad surprise: the wi-fi card was hardware disabled. Unfortunately the tc1100 has an ipw2100 card but no physical hardware switch and without a windows partition I was stuck with the wifi off. I previously had the same problem with a Toshiba nb200, but there I had more luck. The more I think about it, the more I wonder if a linux only system is good in a “Windows only” world.
Disclaimer: following the steps outlined here may brick damage or otherwise set on fire your tc1100 and/or your neighborhood. Please follow them or reproduce them on your tc1100 only if you are willing to damage it, brick it, and set the house on fire. Seriously, this is tricky stuff. I suggest you to avoid flashing the bios if everything is working. If you have to, fully charge the battery and use an external UPS to power the TC1100 just in case. Internet is full of bricked tc1100s. When in doubt, use a real Windows for the flash operation.
Wi-Fi not working after ubuntu hardy upgrade to karmic
I did an upgrade from Hardy to Karmic on an Ubuntu Box that experienced problems with the Atheros PCI wi-fi card in it. The signal was weak (the signal is weak indeed, but it uses to work in Windows, so I expect it to work also in Linux) The box wasn’t upgrade in a while, … Leggi tutto
Toshiba nb 200 wifi kill switch (disable & enable)
I was a bit disappointed last time when I disabled the Wifi under Windows XP and booted from Ubuntu Lucid. The wireless card wasn’t working anymore, with no apparent means to revive it. I had to boot back in Windows and let the magic do his work. I had to find a way to this under Linux without the need for a Microsoft OS and I did

Ubuntu Lucid Lynx on Toshiba nb 200 slow/no boot
I just upgraded to Ubuntu Lucid Lynx and just found that with the provided kernel the boot is incredibly long (more than 5 minutes).
After a bit of upgrading to the last-last kernel available to date (2.6.22-32) with no aid, I decided to have a look around and see what other people were experiencing.
The hidden apostrophe against Openoffice
I had this strange problem importing a regular .csv file into Openoffice.
A field in the file would not be recognized as a number, no matter what I would do during the import process.
This happened chossing ‘Sheet from file’ as well as cutting and pasting into a sheet.
The ‘ is not visible into a cell but is present only in the formula field.
A simple find and replace will not help. Nor it will help setting a the cell format via Format Cell
