I installed Linux Deepin 2014 in my HP Probook 4540s. Brightness of screen is not changing, it so bright so uses more power. Also my laptop got heating problem. How can i solve this problem??

You might want to start by telling us more about your video hardware

Code:

sbin/lspci -nnk |grep VGA -A3

This might be the solution to your problem too

You never supplied your graphics hardware details as requested. Did you also check out the thread I linked to?

Its AMD Radeon HD graphics.

That doesn't tell us much. You run the command (previously given) and supply the output. It may help others provide an answer without having to guess the details.
