Slower pfs when laptop running on battery

[aamiet]

Hi there, I have the Classic version of BYEOS 3.1.17 and I've noticed that when I connect by 700D to my laptop computer running on mains power, I can get around 20fps running in Planetary mode (fairly standard). However, when I run on battery power, the fps rate drops to around 17 fps. I've changed the power settings so the cpu runs at 100% on battery power, and all the others setting I could find to match when running on power, everything I can think of really to no effect. Have you noticed this before, and how can I fix it?

Also, it would be really great to get a histogram view in planetary mode, just so I could check to see if I am using the best ISO/shutter speed for optimum results.

Thanks,

Andrew

This is a function on your PC, not BYE.

Your internal PC clock is probably throttling the data throughput to save power over time. I think if anything can be done I would think it would/could be in the BIOS setting of your laptop ~ just a hunch though.

Guylain's explanation makes sense.

Also, the PC's power plan is likely different when running off the battery and can power down parts of the PC when it thinks that they are not being used. Things like powering off internal USB hubs during a long exposure. For AP this is not a good thing. My solution was to power my PC of a 12V deep cycle battery rather than the internal battery.

Hi there, thanks for your answers. I assumed the problem was with my computer (not BYE) but I was just wondering if you had seen this issue before and had a suggestion. I was hoping to avoid having to get into the BIOS settings, but I'll have a look now.

Thanks again.
