Yes I am running it on a laptop (32bit windows) and it does properly stop and resume when i remove the power.

Hibernation and sleep are not a problem.

I have a dual-core laptop that is rarely on, so I'm using it for trial factoring instead of doing Lucas-Lehmer tests. I'm running two instances of Prime95 24.14, but having to manage two copies is a bit of a pain.

1. I'm wondering if it is safe to replace 24.14 with 25.7, for two reasons:

a. Trial factoring is much more parallelizable than Lucas-Lehmer tests and is less likely to cause errors on untested code.

b. Trial factoring is also more stable, and does not require the self-tests.

2. Also, if I switch to 25.7, will Prime95 automatically detect the files generated by the second copy of Prime95, or will I have to manually merge them into the original files?

It is safe to use 25.7 instead of 24.14. However, you cannot simply replace 24.14 and expect version 25.7 to pick up where 24.14 left off. I haven't written any upgrade instructions. You will have to manually merge your two worktodo files.

Thanks for the information.

By the way, you should change Prime95 such that it checks for "UseV4=1" in prime.ini instead of prime.txt. Parameter switches usually belong in INI files, you know?

You can thank Windows for prime95 abandoning INI files. I've received a ton of complaints that users have invoked a Windows restore feature (to undo a driver or program install or recover from some other problem) only to find that prime.ini and/or worktodo.ini was rolled back to some old date. They end up retesting an exponent, losing an assignment, or having to restore their preferences. Way to go MS.

Speaking of MS, yesterday I had to install a floppy drive on a machine to run Windows XP x64 setup. A floppy!? MS sells an OS that requires obsolete hardware to run the setup program. Anyway, I'm in an anti-MS mood today.

How about abandoning .ini files altogether? For example, the next version of Prime95 could use local.txt instead of local.ini, primecfg.txt instead of prime.ini and worktodo.txt instead of worktodo.ini.

I just found out that Prime95 25.7 already uses text files instead of .ini files. I guess my previous suggestion was redundant.

To clarify, in 2001 MS sold an OS that required obsolete hardware; they stopped supporting it in 2005... Their current 64-bit OS (Vista) can install drivers off assorted sources (floppy, CD, USB, etc).

How about replacing all that .ini nonsense with an XML file?
