Thank you jphughan for your quick response.
I run HDD scan, Crystal Disk Info and HWinfo64 programs for hard drives. All programs said that my hard drive is ST1000LM024 HN-M101MBB/D2. Then i decided to took a picture of him. This is my internal Hdd. I suppose is an 2.5 Hdd. Is this corect? If so , then i can buy the ssd samsung 860 evo 2.5 for my laptop. Thank you aggain for your reply. It was very helpful to me.
