After install it was much better, but then after some updates it was again extremely slow so i tried to update all drivers and updated latest Bios. After bios update is started to use UEFI and said that cant find operating system so i had to install windows again. After install it worked fine for while untill windows updated AMD Radeon graphics driver. I tried many different older drivers, but all had same issues. I downloaded latest AMD driver (2015) from HP product page and that worked fine.
So dont use new AMD drivers for older laptops with AMD graphics!
