So, this issue has been downgraded to Low importance and the status
changed to Incomplete because somebody has noticed that Dave is not
running the latest version of the BIOS on his HP ENVY laptop.
This is a generic problem affecting all makes of laptop. The BIOS on my
Toshiba Tecra M2 does not
Further up in the thread I made it clear that the issue first arose when
running an earlier version of Ubuntu. However, I'm now running Linux
Mint 13. I ran the command anyway, but Mint really was not impressed
because ubuntu-bug is not an official LinuxMint package. It didn't

Although the issue has been solved it has been through the use of a
workaround, rather than a true fix.
The workaround involves an edit to /usr/lib/pm-utils/power.d/disable_wol

You will probably need to use the solution which begins at step 5.

ray@ray-TECRA-M2 ~ $
However, that's the output AFTER having made the edit to disable_wol.
BEFORE the edit, it was
ray@ray-TECRA-M2 ~ $ sudo
I have experienced exactly the same issue on a Toshiba Tecra M2.
Initially, there was no problem using older versions such as 9.04 (I
think). After un update to a newer version the battery drain issue
suddenly appeared, though I cannot now remeber the version number at
which the problem appeared.
