My razer blade laptop won't turn on but when holding the power button

my razer blade laptop won't turn on but when holding the power button logo lights up for a split second (while the charger is plugged in)

when I mean it does not turn on I mean no fans no lights no screen basically holding a chunk of metal

I do recall the laptop having a few issues before I tucked it away for a year or two

issues being keyboard backlight was an eye-burning white and unable to change it/ dim it

also, a dead battery may be though i think there was a bigger problem that i can't remember because I would have replaced the battery and other than that the laptop would have worked well
