Laptop Model - Lenovo ThinkPad T450s. I bought the laptop in April 2024. The laptop's speakers are fine. Its display has a very slight shadow at the very bottom when brightness is set to absolute zero, but there is no problem when brightness is increased. Also, a protector is attached to the top of the display, if that is removed, it will be completely clear. I haven't used it for a long time so I thought I'd sell it. Let me know if you want to know anything, Inshallah I will tell you everything.
