There are no problems with the laptop. To see it, you need to come to the location at Ranirbandar. I use Windows 7, but you can also use Windows 10 if you want. My brother used Windows 10 on this laptop before, but I like Windows 7 so I use 7. You will get a charge backup of 1 hour 25 minutes. The camera is okay, you can talk on video calls, everything is okay. I will buy a phone so I am selling it. 4GB RAM and SSD are installed.
