Hello, I'm not good at computer stuff, and I have anxiety, so I'm worry about this.
I have to be gone for a week, go back to my hometown in China. Here in the U.S. my home have two desktop computers (one Windows 7 and one Windows 10).
Due to away for one week long (7 days), I live in a state prone to earthquake, plus we do have power outage, and when I be gone it will be in the fall, and here in the fall it does rain.
So I really think unplugged the computer is needed (unplugged the power strips from the wall).
But I heard stories about some people said where they unplugged their computer and when they come back from vacation plugged it back and the computer kist won't turn on (due to be off for one week long).
I also heard about the BIOS setting will be mess up or reset itself due to computer unplugged for one week.
What can I do to protect my computer to prevent these from happening? Has anyone go on vacation or work trip that required one week away from home and they unplugged all their computers, what happened when they come back home? Does your computer work again like normal when you plug it back in?
Thank you Sir(s) for your help.

I've never heard of this, but am sure it has happened at least once.  It is possible if your CMOS battery has failed, or fails during your week away, that this could happen.  The odds of your computer being damaged if left plugged in are probably much higher.  If the CMOS battery did fail you will just need to get a new one and reconfigure your BIOS, it wouldn't be the end of the world.


The only thing that you could do to prevent it would be to replace the CMOS battery now and reconfigure your BIOS when you do.  Not necessary, but totally up to you.  I'm of the mind of not messing with a working machine.

If it is any help I am just back from 2 1/2 weeks away and both my desktop and my router were down-powered during this time. Both fired up with no problems when I turned the mains back on. The only minor problem I had was that one of my laptops had gone completely flat in this time but possibly I accidentally put it to sleep the last time I used it instead of my normal practice of shutting it down.


Because I have the good fortune to live in an area with a very stable power supply - we might get an outage once every five years - and also have a very low risk of electrical storms I almost never actually unplug equipment. The most I do is switch it off at the wall. but as Kilroy implied Murphy's Law is always alive and kicking.

There is little that cannot happen, but one needs to look at how reasonably probable it is to occur, not how remotely possible.


I have had machines that have been without power for periods of years, plural, that fire up just fine when plugged in again.  Thus, my impression is that it is highly unlikely that leaving a computer unplugged for an extended period of time will have any negative result.

Unplug both your pc's power strips from the wall.
