I find most don't have the tools such as a Volt meter to trouble shoot. This means you buy the cheapest part that could have failed first then hope. Or take it to a shop where they swap in spares to find out what it is.
Again, you may be hoping for a direct and correct answer but without diagnostics or use of the right tools you only know it is one or more of the three basic parts. The adapter, the battery and the motherboard.
Try this. Unplug the adapter. Remove the battery and then hold the power button for a full minute. Put the battery in and then add the adapter and hope.
Hey guys, I have a xps M170 that has been working fine for a while. But last night When I went to turn my computer on my batterie light was flashing yellow and there was a high ptich humming sound from the computer.
When the ac adapter is pluged in I get this Humming sound, as well as the Batterie will not charge. The computer is not reconizing the ac adapter.
Now when the computer is off and I plug the ac adapter in i get a flashing green Batterie Light.
Any ideas? I think my ac adapter my be bad but I dont want to spend the money if its somthing else.
Thank you Paul
