The system performance of my laptop is very slow now; I think maybe I have too much photos store in the hard disk. I have try to clear up all those unnecessary file and even uninstall some of the program which is no tin use, but still slow like a tortoise. Well, I think I have no choice but to upgrade the HDD space and also the computer memory for a faster speed.

• system perform slow
• Shutter speed and aperture
• not going to bring laptop
