My Compaq Presario 610 Laptop was serviced under warranty ,Which was dead on a lighting stroke.
They replaced both LCD and Motherboard.It took 52 days to return.
But My problem is while using the laptop its going to a pale state,something like high contrast or state which lacks power input.
Its happening only 3 or 4 times per hour. I have noticed it while both in AC and Battery power.
It is strange that it occurs while fan makes noise.
Is there any problem with overheating?
Also I am in Warranty period. Should I return this to the Service center to make an analysis.
Could be your power managment setting. Its possible its droping the backlight down when its not used for a bit. The fan may or may not be relevant. You should check your temps with something like CPU-Z (free download ) to be on the safe side.
If in doubt or your just unsure about changing the settings then get on to customer support. If it didnt do it before then why should it now.
