Question about Acer Computers & Internet
Start up circuit problem, double check the output voltage on the adapter should be between 16vdc -20vdc, if ok connect a load to it example dc bulb/led or the battery of the laptop, if it remains on the adapter is ok, next check the laptop battery, remove it from the laptop and using a meter check the voltage and polarity.monitor the voltage to see if it is falling or holding,it should be holding, if all is well the next step is to check the voltage at the switch, this requires you to take apart the laptop to trace/test the voltage form the input to the battery to the mainboard to the switch and back to the mainboard. if the voltage is not present on the main board you will have to check the components to see which one is defective,if a protection diode it will be a very small component (smd) usually black in color and located close to the input connector.you will have to replace it,which will require some special tools and a lot of steady nerves.if a capacitor it will be brownish in color (smd)Surface Mounted Device.
Hope this helps

Well I am going to need to know at least what kind of monitor you have here. Most likely you will need to contact the monitor manufacturer, or the power supply manufacturer if it is labeled. These schematics are controlled by the manufacturer, but can in some cases be released to the end user.
