Bit busy at the moment and only having a chance to follow this up occasionally - thanks for all the replies!

- I was getting around 2 days battery life with low usage and the Sim in, reduced to around half a day since I removed it (can't restore it as Sim contract cancelled). Unless there's a massive coincidence in timing, I don't believe the problem is with the battery.

- I've tried installing Cellular Modem Control Buttons. It gets to the end of the install, says it's installed, but doesn't show up in the powerkey menu (even after reboot)

- Can't find powertop, where can I get this? I tried fremantle_extras-devel_non_free, but that seems not to work any more, or at least not with my device (fremantle 1.3)

Thanks all

Graham
