I am owner of a company and have a some issue so online business is good for me. Currently I have a i7 PC but it use lot of space and also create noise from fan, recently I upgrade my fan and purchase a expensive fan but still create noise. I try laptop and it use less space and also does not create any noise. It is good to use laptop for office work? I mean laptop can handle like running it for 5 to 8 hours or even more time or it will burn/damaged quickly? Should I keep using PC or switch to laptop and sell my PC? I don't want to damage my laptop by testing it by running it for long time so currently I use it only for 30 minute to 1 hour. Thank you.
