= dell pa10 power supply

Lowest price located (in less than 20 seconds of shopping) was $10 total. This included shipping and handling.

I have been using one of those ultra cheap power supplies more than two years with my BIOS settings enabled (see below). This fully compatible supply has one problem. It radiates enough electrical noise (EMI) that one of my weakest over the air (OTA) TV channels is impossible to watch. This problem is present only when I am within ten feet of the receiving antenna AND the power supply is being loaded... laptop screen on or is charging a nearly dead battery.

If your laptop operates normally and is able to charge the battery, BIOS revision A11 (and later??) allows that annoying message to be turned off.

1. Turn on laptop while holding down F2 key

If Windows is up and running...
press Start and click RESTART (Turn Off takes too long) or
press Control-Alt-Delete
When the Windows screen disappears, repeat step 1

2. When Setup screen appears...
Press Alt-P to reach page 3 of BIOS

3. Use arrow keys to reach and set
Adapter Warnings: Off (Disabled)
4. Press Escape
Save and exit

My dell latitude d610 ac power is work is properly but battrey is not charging plz tell me soulition.

If the D610 works when attached to the AC Power Cord, it is likely that your battery is not capable of taking a charge and needs to be replaced. I have 2 D610 Dell Latitudes and they are very good laptops.
Please vote if my information is helpful or not. Recommend me. Thanks UAW 974

Dell studio 1555 laptop will not reconize charger, charger and battery were checked on another laptop and are fine.

Thats a hardware issue of your laptop. You'll need to take it to a service centre to fix it, hope you still have your warranty left.

It's hard to say for sure, but it sounds like you might have a multiple issues going on. Are you able to boot the laptop with only battery power (the AC adapter not plugged in)? If so, then the culprit would be the AC adapter which you could order from Dell (or other places). If it still has issues even on battery power then there is something wrong with your operating system (Windows). Good luck.

Certain models talk to a chip in the adapter, sounds like this one has gone bad. At this point you can live with, buy a new one or pick up a used. This is a fairly popular model and you should be able to locate one from a dead laptop.

When you received the system as out of the box and you get this message "The AC power adapter wattage and type cannot be determind" let the Dell tech service know that they sent you a wrong or incorrect type of AC Adapter.
If this message not was not appearing before it just happened recently try to download and install the latest BIOS version from the support site.
If all fails remove the batt and check if laptop can work with AC adapter alone, because issues like AC not determine may not charge the battery and laptop may not work with AC as well, maybe laptop is already running on battery power.

A message keeps coming up on my Dell laptop saying the AC power adaptor cannot be determined, this will prevent optimal system performance...what does it mean and what can I do?? Nipper

Dell portable systems use a sensor wire (Thin wire in center of power connector of AC adapter) to allow the system to identify the wattage of the adapter connected to the system. If the wire is bent or broken, then that message will appear and the battery charger is disabled.
If the issue still occurs with a replacement or known good Dell AC adapter, replace the motherboard.

I have a Dell Latitude D610 and it was apparently working until 24 hours ago when I used it on battery mode for 1 and a half hours. Currently when I switch it on, I constantly get this message that my AC...

When the message about optimal performance comes up, are you given an option to press F1(or some other key) to continue? That is normally the case. If you see that, press the key and let it start normally. Once it has started completely, do a full shutdown. Disconnect the AC adapter from the computer and from the wall. Let the system 'rest' for a few minutes. Connect the adapter to the AC power and check to make sure the GREEN led light on the transformer is lit. If it is, connect the power supply to the computer and start it.

Good luck and please let me know how it works oout for you.
