1.5 year old notebook-HOT!

in the past few months my laptop's been running hotter than ever.
I've got an old 3000 N100 model.

But i think i've identified the problem, but it seems weird to me.
So, my laptop runs hot hot hot when it is plugged into the ac adaptor.
If i unplug it and run using the battery, it cools down by an amazing 10 degrees Celcius.

Should i consider getting a new power adaptor?

 

Maybe you should set the CPU to run in low power mode while on AC, which it probably does when running on battery.

 

Try getting some compressed air and give all the vents a good spray down.

 

What Kind of environment u working with

 

ditto.

I think if that doesn't work you'll have to go inside.

 

Best to take the laptop apart and hold the fan down while doing this. Otherwise he might damage the fan motor...

 

Doing this will not damage the fan motor. I have done it countless times on countless laptops/pcs and the fans are still up and running.

 

He is just mentioning to hold the fan blades stationary. If you blow compressed air and let the fan blades (thus motor) spin at an uncontrolled rate, it may cause damage in the long term.

@OP: You may want to look into a cooling pad (search the forums for Cooling Central) or undervolt your CPU (see my sig). A pad is simple but undervolting may be more efficient. Take a look and see what fits with your level of use. You may want to consider sticking to a 3-6 month cleaning cycle. I know I use my laptops in a lot of different environments, and thus I collect dust...so I am constantly cleaning the vents and ducts. Best of luck to you!

 

that's what she said

 

It sounds like the problem is with your power profiles. When you're plugged in, you're probably on the High setting, which keeps the CPU speed at its highest. Switching this to Balanced will let it throttle down during light loads.
