Extremely dimmed laptop that does turn on but I can barely see a thing

[nakeishalaptopss]

No damage would have caused it except for it being placed down to hard. I can see the login page to enter details but it’s extremely difficult to see. It’s really dimmed. Please help

what is the Fn+brightness up key? have you tried manually turning up the brightness via the keyboard?
is the backlight on?
