i am using dell inspiron 1525, more then 12 hours a day. but i am not sure this is good or not becaz i buy this labtop 5 months ago only.
My laptop runs 4-6 hours a day... I prefer to use computer because my computer have better cooling systems.
actually, means summer time, I don't work too much on my laptop. I think I need to wait September to go back to my usual daily working hours. at the moment probably I just check emails and write in forums. not very busy
I usually use my laptop 2-3 hours per day. If I have homework or other things to do I use it for longer periods of time ofc...
