text: what can i do to keep power cable on my laptop from getting really hot? the power cable that goes to my laptop gets so hot and i don't know what to do. cooling systemms are made for the laptops themselves but what about the cable? please help! i would suggest getting a new cord.  just right down the information that is on the cord (voltage and resistance and such other things) and take it to your closest computer store and tell them what you need.  i have noticed that laptop cables do get hot sometimes, but that's only on old ones that i have seen--so it is probably time to replace it, if it is old.  note:  resistance in electrical systems generates heat energy.  so, keeping that in mind, you may want to get a cord with less ohms/resistance.
