i have an acer aspire 7520-5757 will only start if I unplug the ac adapter?
After it starts I plug it in and it charges the battery ect. If I click to restart the system it does. If I shut it down then I have to unplug the charger again to start it. Also if I enter the cmos then save & exit it shuts down instead of rebooting to windows but only with the charger plugged in. I have changed the dc jack and that was no help. Anybody know what is causing this? Thanks
