Blinking light on laptop ac adapter

jbcbussoft asked
Last Modified: 2013-11-17
I have a Sony Vaio VGN-CR220E. The light on the ac adapter glows bright and then dim. When it is dim the icon that shows the power condition switches to battery power, when it is bright then the icon shows it is back on ac. With the adapter not plugged into the Vaio the light glows brightly. Has anybody seen this before?
