This is likely either a defective transformer on the external power adapter (not likely, but possible) or defective wiring in the external adapter wiring or the internal PC board. If you have a multimeter, set it to DC volts and put one lead inside the power jack of the adapter and the other lead on the outside portion of the jack and then plug in the adapter. You should see the rated DC output voltage on the meter (rating is usually on the bottom of the transformer, or big boxy part of the adapter). If you don't have that voltage then it is likely a defective adapter. Like another helper mentioned, try either a friends IDENTICAL adapter (don't use just any adapter or you could damage your computer!), or a universal adapter to make sure. I've seen many adapters with broken wiring in the jack, most often due to bending and/or stress when it sits in a tight space most of the time. If a new adapter also doesn't work then the computer requires service from a service center.

It could be an issue with the power cord, it it could be an issue with the computer accepting the charge. The only way to test is to get another power cord that matches the exact same one you have, or to find a univeral power cord that is compatible and see if it will use the external power this way.

Inspiron 4150, won't boot up

I would try creating a start-up disk on either CD or some other portable media and see if the machine will boot to that. Before you decide to use the computer for a door stop Take it to a Dell Service center to have it checked. It could be a simple switch has gone bad or something more serious, you never know. There is no real need to lose the data on the computer. You can always remove the hard drive and put it in an external box to get the data that way. Just remember to tell the service shop you take the computer to that you do not want the drive erased, Deleted or formatted when repaired.

Dell PP29L backlight turns off on external power

I'd try:

Updating the bios to the latest version
Uninstall video driver and check for newer version
Replace the inverter.

Let me know if any of those suggestions work, if not we can try something else.

My inspiron 5160 doesnt power up.

It should power up with the external power supply if it is working properly; you can remove the batteries and it should still work with the external source. If not, then the power section on the laptop is dead and needs servicing.

Dell 4150 will not use AC power

Only way is to open it up and check that you're AC connector on the board is ok. If that's fine than it might be the charging circuit.

4150 inspirion keys ( W,S,X) stopped working

Hi,
As told if you have already put in the new keyboard and still the problem is there, it could be the problem with the motherboard connector. To pin point the problem , connect an external keyboard to the USB port of the laptop. iIf the same works good . The motherboard is the point of failure .



Thanks

Won't boot up

Can you give a little more information? Did the Laptop Fall? What Color is the light that blinks? Amber or Green?
So far it Sounds to me that you Power Supply is Dead or Bad and or not charging the Battery....

First Check the battery status light?
Is the Power Supply Light (Lite). you might want to try removing the battery and using only the Power supply!
