CQ61-410US running Windows 7
Laptop starts up fine getting all the way to the login screen; no alarms or error messages.
Whether you login or not the display will dim after about 15 seconds and turn completely off in about another 5 seconds.
If I connect an external monitor the screen will come back on along with the external monitor, but will turn off again leaving the external monitor on by itself.
If I unplug the external monitor the screen will turn back on, but again turn off after about the same amount of time elapses.
For testing purposes I set the Power Saving settings that effect the computer going to sleep or turning the monitor off are all set to 'never'.
The computer can be used in this condition if I wanted a desktop, but that isn't the way it is supposed to work, or the way it used to work.
