Windows 7: Up time duration

Hello!

I wan't to ask for opinions and experience.

How long is too long? most of the days I have my laptop running for 10 -11 hours...I don't like to turn it on in the morning and then turn it off at night, because then my laptop is on for 13-15 hours.
Is there a difference between 13 hours and 10 hours?
Does longer means shortening MTBF?


According to my laptop failure times, 10 hours each day equals 5.5 years...although I am not sure how accurate it is.

Thanks for your help!

Welcome
Your question brings back the old question, Is it better to let the computer sleep or turn it off each nigh. In the old days turning on and off would cause damage, due to the constant heating and cooling off. This is no longer true today. Most people would turn it off over night, but even that is not necessary. You must turn it off once a week or so, to let the computer boot. It is during boot that small corruption and problems are repaired and any depleted memory is restored.
Bottom, line enjoy.

No such thing as too long. A pc should be re-booted occasionally to clear memory and pagefile but there is no finite amount.

Many people leave it on for days at a time. The difference between 13 and 10 is three hours thats all. Not relevant to the grand scheme of things.

MTBF is the average time between problems (failures). the longer the computer is on the shorter the time till the next problem

Why would it cause damage?
Why doesn't it cause damage these days?
I mean, obviously keeping any electronic device on for too long will harm it, and gradually reduce its lifetime.
So I have to disagree.

Keeping it on during the night is unnecessary, you don't use it, and as I said before it is only going to cause problems.

You said it yourself, "the longer the computer is on the shorter the time till the next problem", you can't keep any electronic device on forever, there will be failures.
And I am not talking about "clearing memory" but hardware failures.

Computers are made differently, today. There is no damage if you leave it on. Two members have basically given the same answer. Just enjoy.

I Just hate it when people tell me things that I do not understand.

But thanks anyway.

I have to agree, with you. I would not like to be left hanging. Maybe, this will help explain it better
HowStuffWorks "Is it better to turn my computer off or leave it on all the time?"

This is pretty much a useless exercise. There are ppl who will tell you to leave it on and those who will say dont. Were I you, I would do what I wanted.

Okay thank you!

And thanks for the HowStuffWorks link!
