Is it ok to leave my laptop plugged in?

I use my laptop all the time now. Is it ok that I have it plugged in 95% of the time instead of using the battery?

Lately my fan has been coming on too much, even though its elevated to let air circulate under it and in nice room temperatures.

I'm typing right now and the area under my palms feels pretty hot.

Should I unplug my laptop when I put it into sleep/hybernation?

 

I think you are fine. Make sure none of the vents are clogged. Might also want to check to see what is running in the background.

 

Plugging your laptop in and overheating are two separate issues and have nothing to do with each other (or at least shouldn't).

Overheating is usually bad air flow - I took my old 2500 apart to find it clogged with dust and dog hair.

It could be a bad fan too, but you would probably hear it going bad (ie bearings). Also (but more uncommon) is the cpu, heatsink, conductive grease connection.

I always leave my laptop plugged in - no problems. In fact if you use sleep instead of hybernate, it's a very good idea. Sleep mode turns the computer off but supplies power to your memory. Hybernate on the other hand copies your memory as an image to your hard drive, it requires no power after that.

Hope this helps,

i 100% time plugged in the power supply. and many time run it like server. but im not sure when i shutdown the computer do i need unplug power supply?

 

The heat under your palms is the hard drive, my friend,

My dv5000t gets the same way sometimes, especially if I've left it on with the lid closed overnight and open it up. I also have a 7200 RPM hard drive, which puts out a little more heat.

Edit: No Boai. And to answer the original question, it's fine to leave your laptop plugged in. Literally millions of college students have helped work any such kinks out over the past few years.

 

Typically, laptops will use more power when they're plugged in than on battery because they turn all the power management stuff off in search of performance. That will make the fan run constantly and may make it run hotter depending on how good the fans are. If all you're doing is web browsing, you could change the power management options to conserve power (at the cost of performance) even when plugged in.
