Acer Aspire approx 4yr old

this laptop will not turn on? Could this be a power source or cpu problem?

Is this with just the battery or when plugged into a wall socket?

the psu(power supply unit) on your laptop may have a problem and therefore I recomend you to open the laptop and try to clean it first from all the dust as dust usually results in clogging the motherboard and the try to turn it on and see if the fan is spinning.
