Hi,
when I turn my NC10 off , say at night when its fully charged. I close windows and shut it down completely ( yes I know about sleeping and hibernate). It is not connected to the power supply. When I get up in the morning, I can feel the front edge underneath where the air holes are is warm and when I boot it says I’m down to 70% battery. It is most definitely warm, cos if I put it in the bag too, you can really feel the heat through the bag. Any ideas why it is still using all this power? I have swapped out out the hard drive for a bigger unit (Fujitsu) and put in a dell 1490 wireless card for OS X use
TIAAbsolutely no idea on that one…!! To make sure it is properly shut down you could remove the battery pack and put it back in again.
I was make the same suggestion with battery removal, but as to what might be draining power…. !dodge
It doesn’t matter if it was osx or windows it was closed down from. I don’t know about the usb power, but I had no usb devices attached at the time. I will try with the battery removal/ re install at some point too

[/quote1238082889]Are there any lights on the bottom left still on after you have shut down the NC10? This sounds very strange. If the NC10 was in hibernation or standby overnight it would not deplete the battery as much as 30%. And if it was actually ‘on’ there would be more than 30% battery depleted.
I wonder if when you swapped a part you inadvertently caused a short somewhere, maybe with enough resistance not to trip the machine.
It may be worth leaving the machine off for a while (overnight) then open it up and try to see where the heat is being generated.
PS, I would remove the battery on your own risk. If the battery is draining somehow, that means it is running. So pulling the battery off while it is running is not safe imo. Just a friendly caution.

I wouldn’t expect there to be any problems caused by disconnecting the battery, personally it sounds like it may actually be a fault and so leaving the battery connected may be more dangerous.If the computer was running then there is the possibility of corrupted files, but it doesn’t sound like anything is actually running in this case.
OK,
It is all ok now. Disconnecting the battery for a few seconds seems to have reset something, as it no longer gets warm and loses charge when turned off using xp or OSX. Just to make it clear, I have only reset it once. The part that was getting warm was the bit under the LEDs on the front. I’m not sure what is under that part in regard to circuitryThanks for everyone’s input

[/quote1238244302]Thats near the RAM and CPU. Did the NC10 have this problem before you swapped the Wifi cards? Maybe try putting the Atheros card back in to eliminate the new Wifi card being the problem.

This would disable wlan on mac osx but for testing purposes it migth be worth a try.
