The error refers to a memory failure.
Start by unplugging the system, removing the base cover and disconnecting the main battery from the system board. Hold the power button for 30 seconds, remove and reinstall the memory module(s) and reassemble the system. If it will then power up, you're set.
If you have only one module, move it to the other socket and re-test. If it works there, the first socket is bad and the mainboard will need to be replaced. If it fails in the other socket, either the module is bad or the mainboard is bad.
You may want to try a new, compatible memory module.
If there are two memory modules, try them one at a time in each socket until you isolate the bad module (which will fail in both sockets, while the other one works) or the bad socket as above and replace the faulty module or the system board.
