My hp laptop won't work. ?

Well I have a HP laptop and it won't turn on. I tired to reboot by turning it off taking the battery out and unplugging it multiple times. It still hasn't worked. I know that it's somewhat alive because the cap lock key and the scroll/number lock key are blinking. It hasn't been working since June 22. I would like to know the cheapest, easiest way possible. I have a Person who will fix the laptop for free but I won't be able to get my laptop fixed until Thursday.
