While many people complain about small battery life on notebooks, I'm much more annoyed by a hot one.
Normally, the best way to avoid this is by disabling flash on my browser, using click to play for every plugin etc. I also keep an eye on task manager to spot processes using too much CPU.
Firefox has been the biggest culprit of heating my laptop, bringing the CPU from comfortable 45ºC to over 80ºC by using 120% of one CPU and keeping this way indefinitely. Is there a way to avoid this?
Any ideas?
Support Data I use a Macbook Pro with Yosemite but I have the same issue on my other macbook pro with Mavericks.
