You would need to check the voltage output under load. It should be up to 5.2 volts but do not exceed that. There is an adjustment pot on the power supply to tweak the voltage. Usually it is a matter of it being too low. If you do not know the history of the G61R then you should replace the power supply as a proactive measure. A replacement can be had for around $65.00. There are some capacitors that should be replaced as well.
