Dell XPS M170 Power Issue, Please Help!!!!!

by paulsapio / October 13, 2010 2:28 AM PDT

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

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.

Thank you Bob, is there a way that I can try to power on w/o the Battery? To see if the computer will run on the ac adapter?

All laptops I've seen in 20 years can run without the battery.

That the adapter or the laptop has a fault. I'm guessing here that you are looking for something cheap or a reset. I've already shared a generic reset. If that fails laptops have only 3 pieces to replace when you see this failure. You know that it's not the battery so we are down to 2 pieces. The adapter and the laptop motherboard.

My advice is to replace the cheapest part and if that fails get a price quote on the repair. If that quote is over half of a new machine, get the new machine.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
