coming up to an hour after installing the battery patch again. no reboots. Saw there is now a battery patch for non power users, so tested that one. Went back to the 'benchmark' test of trying to play an iplayer vid and it worked perfectly. A bit weird that the battery patch made a video run smoother, but lets not complain if it works eh? Just hoping for no reboots now.

So, to recap, looks like if you are geting random reboots, just removing then reinstalling the patches does the trick. Or, as mentioned previously there was someone who uninstalled everything and reinstalled it all again in a particular order, So if just reinstalling don't work, that method might.

PS. no funny clock speed settings changing yet either, so that is all normal (that'll be what the real problem was all along- updating power48 must have interfered with something in the script about clock settings, reinstalling seems to have fixed)
