Running LL test w/o aging my computer?

Is it possible to run Prime95 doing first time LL tests without damaging my laptop?

Nope.

The only way to not do any lasting "damage" that is not just simple ageing is to not use it.

Put it in a sealed lead-lined vacuum box without power and it might last 100+ years.

Wouldn't the lack of any charging cause the main battery to fail in short order, and the RTC battery fail also in a few years? I had exactly that happen on a couple of laptops. Also desktops can forget their BIOS settings if left off too long.

Batteries provide power. That is why I suggested to not have any power.

Anyhow, batteries are a consumable item and shouldn't be considered as permanent. Which means one shouldn't buy a laptop with an "integrated" battery. Because then the battery becomes the limiting factor, while everything is still running fine.

Perhaps I should have said *prematurely* aging my computer?

All usage will advance the degradation process. Heavier usage advances it faster.

I've run 24/7 various distributed computing tasks on most of my laptops over the years and the main issue to deal with is cooling. I've never had any failure of CPU or other silicon in any of them by the way.

You didn't mention anything about your specific hardware, but assuming it has fans, then I would expect those to eventually wear out after a couple/few years of constant use. You'll do well to keep the vents clean, and possibly apply better thermal paste to help deal with temps. Also may help to have the laptop on some type of stand/standoffs for better airflow underneath.

Try running it and monitor your temps during the process. Then ask yourself if you are comfortable running at those temps for extended time. That's a decision only you can make.

If your laptop is running too hot then either use Prime95's throttle feature or run it on fewer cores.

Use fewer cores. Throttle may well be worse than running flat out (temps will be lower but the never ending on/off cycles is very demanding).

True, heating up and cooling down could spell disaster. On Linux there is cpulimit. Maybe there is something similar for Windows.

Good point. I was considering throttling when that issue of constantly shutting on and off even for short spans of time was bothering me. Is there a way of designing the throttling feature so that it uses all the cores but uses a lower percentage of them? I can spitball some ideas, but one idea is something more along the lines of forcing another component of the computer to become the bottleneck, thereby easing up on the processor and resulting in cooler temps? Otherwise it seems that the benefit of throttling via the old method back in the day has turned into a drawback.
