Solved Recommended power settings for Windows 7 PC

Specs: several
In another thread today, OtheHill recommended to a
Windows 7 user:

> Go to Windows Control Panel> Power options> Create plan.
> Then set options as you wish. I recommend you set Hard Drive
> and USB settings to never sleep.

Could you explain those recommendations, please?

I'm currently using two laptops -- an ancient Dell running Win 98 SE
and a new HP running Windows 10. The Dell's battery was nearly
dead when I got it secondhand almost ten years ago, so I have only
ever used it on AC. I haven't taken the HP anywhere, so I have only
used it on AC, too, aside from once or twice when I didn't bother to
plug it in. So running the battery down isn't a concern. I don't trust
the colors on the HP screen, though, so I plan to get a good quality
monitor, and will probably get a whole new desktop system then.

If any of that makes any difference.

The Dell hard drive is set to turn off after 5 minutes while on AC.
That is 1.4 seconds less than the time that passes before it needs
to save or retrieve data again.

The HP hard drive hardly ever shuts down, because it is always
finding something to do in the background, despite having deleted
dozens of tasks in Task Scheduler, disabled scads of Services,
and uninstalled almost all the bundled software.

Hard drives traditionally fail on spin-up / spin-down, so limiting those actions by keeping the drive awake theoretically saves drives. It's less of an issue with SSDs.

Not sure about the USB thing; I know people who keep their devices awake so they can charge their phone while their PC sleeps. Maybe it has something to do with some buggy USB device OtH used?

I always set my desktop machines for Hard drive to Never power down. I do use sleep but set it also to Never and initiate sleep manually from the start button. I find that when you have the hard drive power down you create some issues, the primary one is that if you use hybrid sleep on your desktop they sometimes get frozen and do not wake up. My theory is that the hard drive powers down before the hybrid sleep saves a copy of the RAM to it and cannot continue. This has always worked for me. Since I switched to SSD drives I found that some drives have problems with hybrid sleep and find that disabling hybrid sleep and using regular sleep to be better and solves not waking from sleep on SSD drives.
I do not make any special USB settings. I do make sure that the BIOS is set to not to wake to LAN because it wakes at random times in the middle of the night (annoying if it is in your bedroom).
