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