Code up a mini battery monitor? Funny This still defeats the point of all the automaticity that comes with prime95.

There is probably a converted script to use PowerShell out there and seems more correct if you using Win7.

You could code up a mini battery monitor with the script and stop/start P95 accordingly

or if you want to access the information at a lower layer

Yes, I realize it does cause you to withdraw your "feature request", but I thought I'd give you some ideas for possible solutions until your request is implemented.

I'd like to make a second push for this feature request. My laptop charges pretty well but I turned Prime95 back on while I was teaching for two periods, plugged in, and my battery power went only from 15% to 31%. That's really not enough for me to simply let Prime95 run in the background while plugged in because it doesn't let the laptop charge fast enough. I suspect others have the same issue.

Out of curiosity, what is your CPU?

Today is your lucky day. Add BatteryPercent=90 to prime.txt. This will tell prime95 to halt until battery level reaches 90%. This feature has always been available in Windows but is not in undoc.txt (I'll fix that).

You're my favorite person for the next 23 hours and 59 minutes. Congratulations!

You are also lucky you could charge at all. I am pretty some people have lost charge when using prime95.

Comment: I am running Prime95 on several laptops (always only on AC power) and have never had an issue with the charger not keeping up. Could it be you need a new/different battery?

Question: does anyone have experience using Throttle=n?
I just tried it on my i5-2520 Laptop (Dual core Sandy)and found the results "interesting"
- no Throttle: temp stable at 77&84; iteration time .023
- Throttle=80: temps fluctuate between 65 and 88; iteration time: .021
Why are my iteration times better? Is the ocassional 65 degrees really enough to have it run faster overall? Could it be only timing during the 80% of time it is running?
Might constant temp changes of 20 or more be harder on the hardware?
Could my cooler be being fooled that it gets hotter at times with throttle?

I put both of my laptops on Zalman fan bases. The big, slow fans have a soothing sound. I am using the ZM-NC3 model.

That is normal. Nothing magic, your CPU is not "faster" at 65C, but it does "hardware" throttle (thermal protection jumps up and turns on) upper, when you don't use the "software" throttle of p95. The one employed by p95 is just "work x% of one time slice, stay the rest". Your CPU has enough time to get hot and cool in cycles (I mean visible cycles, one second or half second each period). "Time slice" depends of how fast p95 can fill and empty its caches. It could be nice to be possible to adjust that time slice (period), beside of the percent, but that depends of how fast the data is loaded/tasks are switched, it may not be so nice to stop it and clear the cache too often, therefore is hardware coded inside of P95, you can only specify the percent. P95 will chose that time slice depending on the work it has to do, and the percentage.
