I am keen to learn if this problem was ever resolved in later kernels. The reason is that I would like to wipe winXP from my netbook, but I am concerned the battery drain problem may return.
I quote from my previous post of 2010-06-02: "I had this problem on my new Toshiba NB200-10G; BIOS v1.2; Ubuntu 9.10 NBR (dual booted with XP) When I disabled Sleep&Charge from BIOS Setup, the setting would always revert to enabled. I then found a tip on an OpenSolaris thread which recommended using the Toshiba Sleep&Charge utility from within XP. This utility appears to control Sleep&Charge for both mains and battery situations, ie more elaborate that BIOS setup options. So I disabled Sleep&Charge using the Toshiba utility and my battery drain problem is now solved. Unfortunately there seems to be no Linux version of the Toshiba utility." This workaround using XP to access the Toshiba Sleep&Charge utility was persistent. Once Sleep&Charge was disabled, it stayed disabled and I've never needed to use XP subsequently. I've since upgraded to Ubuntu 10.04 LTS Netbook Remix and this setup performs impeccably. However XP still occupies a large fraction of my disk and it would be nice to eliminate it, but I am concerned that I would then have no access to the Toshiba Sleep&Charge utility and that if Sleep&Charge somehow became enabled again, the battery drain problem might re-appear. If this happened, I'd be stuck with no way to disable Sleep&Charge again as I'd be unable to use the Toshiba Sleep&Charge utility which can only be accessed from XP. Sorry, if this is long-winded, but I am trying to be clear. It would be music to my ears if any gurus could confirm that the kernel has been fixed and that there are no problems with Ubuntu 12.04 LTS.
