Try unplugging the battery and turning it on with the battery removed. In some situations, the battery itself will prevent the computer from powering on. If that doesn’t work, try reseating the RAM module(s). If there is more than one, try starting it with each one individually. There are numerous things that can cause this type of issue, it’s just a matter of running through each of them to find the culprit.
