Hi Coleslaw

Now there's an idea...I run this 99% of the time on mains since the battery is sooooo old it has a max life of approx 90 mins - less with brightness up and wifi on...I'll try max performance settings in XP and see what happens.

BTW it IS an old laptop - I've had it approx 8 years - and it still runs!!! I used to fold on it about 6 years ago (username physio), when I found that the units typically ran slightly slower than my desktop PC. Both pieces of hardware are still in use - the only difference is that my desktop (main workhorse) now runs Linux Ubuntu 12.04.

BTW Previously average time per result was 8 hours then under XP, whereas now under Ubuntu is 7h30. Obviously the unit contents has changed over the years, but it is still a big shout from the 14-22 hours estimated for each work unit at present.

I'll put the settings on max and post back when I have something conclusive (or not!)

Many thanks again for your thoughts and replies.

This is certainly a helpful and friendly forum!

Lots of laptops of accelerometers, but last I looked QCN had only some 1100 devices reporting data. It really takes on my HP about 0.01% of CPU time to run this.
