Lenovo G50 not wanting to power?

I hit my computer a bit because it was slow but when I power it on, it just says Lenovo and shuts down. No spinning circle at the bottom. What is this?

So apparently errors no longer get displayed during power on self tests or anything… Sounds like today, where you get to know nothing going on cause everyone is assumed to be illiterate or something.

Try pressing and holding F2 or escape or F8 during each of the starts, differs between computers, but one should open the UEFI setup, the other should open boot menu, and the other should boot into drive's recovery partition.
