Interesting !!!!!

My Dell PSU is a 90W one and when I first connect it the laptop is running from the power supply and it is charging but after a while the inverter shuts down. Flicking the power off and on again to the inverter restores power for a while. The inverter doesnt seem excessively hot when it shuts down so not sure what is happening.
