Disconnect the laptop from the wall, disconnect the battery from said laptop, remove the stick(s) of ram, then press and hold down the power button for 30 seconds. Use an eraser to wipe the gold contacts on the stick(s) of ram, wipe clean off of any debris from the eraser, then reseat the ram. If you have two sticks to work with, slot in one for now. Then hook up the laptop's adapter(not the battery) and see if the laptop powers up. If the laptop powers up successfully, you can power down, disconnect and reseat the other stick of ram, then power up like last time with the adapter.

If the above checks out, then disconnect from the wall and replace the battery for the laptop(not the CMOS battery mind you).
