История для "Power button blue but screen is black"

I haven't used this laptop in 4 years but when I go to turn it on the power light turns on blue, has a little start up from what I can hear then nothing. Screen stays black no logo. The two out of the four light at the bottom of the laptop turn blue but thats it. Its fully charged. Any help? Or has it been too long?
