Laptops can still have problems....
I think Linux Mint is one of the best...remember I am talking a system that allows you tolive on the web and worry very little about going to any website.
Windows is great for just about everything except dealing with the bad stuff on the internet.

But back to the problem...if the heatsink fan is turning...that usually indicates the machine is working...so why can't we see a BIOS screen...hmm?
Have you got a keyboard with a PS2 plug...or an adapter for the USB to allow the keyboard to plug into the PS2 port...?
Could be a keyboard problem.
Could be a motherboard problem where the portion of the Mother board that drives the USB interface is failing...I've seen that.
Usually an indication that the Motherboard is on its way to the great beyond.
If you have another keyboard you might want to try it on the machine.,
How do we know that the Monitor is working?
Just having a light on isn’t enough.
Those darn Broadcom wireless cards.

You never know what's going to foul up the works. Back around 99 or 00 my company (finally) switched from the clackity old IBM terminals to a batch of shiny new Dell PCs. About a week into it our service manager's PC froze and he didn't know what to do. Our IT guy was 100 miles away at the main store, and it's not my trade but since I was known to have the most knowledge among those in the store, I was called upon to solve the problem.
By the time I got to his desk there was a column of smoke rising out of.... his mouse. Never saw a mouse go out in flames before or since, but that was the primary failure and a replacement mouse got everything working fine.
