I have laptop G6-2005AX of HP make running Windows 8.1 Pro 64 bit. The processor of this machine is AMD A8-4500M.
When I boot machine fan is running in full speed (I can hear it). Now if I activate sleep mode and restart it from sleep mode, fan runs in normal speed and now I cant even hear it. So fan misbehaves only on fresh restart, and after sleep mode it runs in normal speed. It has become kind of standard practice for me to activate the sleep mode after every booting.
Please advice why this may be happening.
