Question about Dell Inspiron 6000 Notebook

5 Answers

New Dell battery, new AC adapter(not Dell). Won't charge battery

It seems Dell has a system intercept to keep you from using any adapter but theirs (at twice the price). Is there anyway around this as the battery won't charge and I must use the system on AC only with battery removed.

Need answer ASAP

    You miss the problem completely. The battery is good! The adapter is good! The adapter is NOT official DELL, so it will not allow the battery to charge. I get a message saying.."System cannot identify the adapter attached to the computer, so the battery cannot charge"

    System is Dell Inspiron 1501

    Please repost

    I have the same problem, the battery is perfectly fine. The adapter is perfectly fine, the power specs match up perfectly. A message actually appears that says something to the effect of, "this is not the proper dell adapter, your computer can run off AC power but the computer will run slower and the battery will not charge." Is there anyway around this?

    would i need to replace the motherboard to fix the problem? because my battery wont charger either. its a brand new battery. it came with a charge and worked fine. now its dead and i have to run off of ac power

    I have a similar problem. Just out of the blue, I received the error message that I was not using the correct power adapter. Funny, since it is the same one that came with the computer. Hasn't charged since.

    I have the same problem on my bn-vf823 camcorder battery too, but i bought a another bn-vf823 battery from ,When I received this replacement battery, I felt the shipping is very fast! After i used it, I felt very surprised, because it fits nearly as good as the original battery. and it take a power suply to work with my camcorder. so, i want to share this best replacement battery.

  • nomoredells Apr 13, 2009

    Let me put this simply:
    1) I have two Dell Inspiron 6000 laptops (puchased at the same time)
    2) I have two Dell OEM batteries (both good - believe me)
    3) I have one Dell OEM charger and one knock-off charger with the SAME specs as the Dell OEM charger

    Issue; the Dell OEM charger runs and charges both computers perfectly, the knock-off charger only runs the
    computers it does not charge either computer battery. I have tried all possible combinations. As either computer boots up a message appears on the screen saying " THE AC POWER ADAPTER CANNOT BE DETERMINED. THIS WILL PREVENT OPTIMAL SYSTEM PERFORMANCE." I need to know how to defeat this surprising shortcomming with my Dell computers. I will not be buying an overpriced Dell charger for a 5 year old computer.
    Please, does someone have a SOLUTION other than "buy a dell charger" or "you must have a bad this or that"
    Thank you.

Dell uses a proprietary SMBus protocol over the center pin to communicate the type and power capability of the attached adapter. The laptop uses this information to determine if it can charge the battery without browning out the motherboard. If you use a knock-off power supply that doesn't communicate properly (or at all) over SMBus, then the computer will complain and won't charge the battery. Sorry, Dell has us all right where they want us. Find a used actual Dell adapter on eBay for $20 if you can.

I think that the problem is not the AC adapter, it is in the board of the computer.

1.- Computer AC / DC cable is bad not allowing the computer battery to charge.
2.- Battery is bad.
3.- Battery charger board is bad.

1.- Computer AC / DC cable is bad not allowing the computer battery to charge
Verify that the AC and or DC cable is not bad by testing the computer only with the power plug connected and the battery out of the laptop.
2.- Battery is bad
It is possible that if the power plug is good that the computer battery is bad. Leave the computer connected to the power with the battery connected in the computer for at least one hour; if the battery does not charge, consider having the battery and/or the laptop serviced or repaired.
If the computer and/or battery is not in warranty consider just replacing the battery as it is very likely that it is just a bad battery.
3.- Battery charger board is bad
If the battery has been replaced or an alternate battery from an alternate identical laptop does not work in the computer, it is likely that the power or charger board within the laptop is bad. It is recommended that the laptop be serviced or repaired.

The wattage on these knock offs is not high enough to power the computer and the battery at the same time. The knock off is less than 90watts while the original is 150watts.

Also the original has 3 leads going to the computer while the knock off only has two. I think there is some sort of communication protocol going on here too.

Maybe the adapter you are using is not the same as the Dell one.
There are a few things to check out.
On the adapter itself you should have a label on there you will see the rated amps and output voltage.
For a laptop this usaually between 9v and 24vDC.
There will also be a little graphic that tells you whether the inner core or the outer core of the plug is positive or negative.
If you click on the link below you will see what I mean.
This on indicates that the negative is on the outer core and positive is on the inner core.
So you will need to get an old adapter to check what yours is.
I have a Dell Latitude mine is 19.5v and the inner core is positive. The output is rated at 3.34 amps.
There is no inhibitor to stop you using any adapter you wish it just has to be the correct Volt, Amps and positive/negative core.
You will have no problems running on just AC power if you have the correct adapter.
Let me know if this is helpful.

Dell m5110 laptop won't charge new battery and ac adapter is not recognized in bios

Try another AC cord/charger with the EXACT same specs as original. Is the battery a genuine Dell battery, if not return it? Some aftermarket laptop batteries don't play well with your computer, the pin-out connections aren't correct and MAY be a fire hazard.

My dell inspirion ac charger will keep computer running but will not charge my battery. A pop up will inform me that the system doesnt recognize the charger.

it could be a couple things: Are you using the standard 90 Watt ac adapter, or the Travel auto/Air adapter. The travel adapter is only 65 watts can will charge the battery
If using the standard ac adapter, see if you can try another Dell D series adapter and see if you get the same error.
If same with another adapter, the issue is the charging circuit. If another adapter works, then replace the adapter.
If the charging circuit is bad, it will be the chargerboard or if intergrated, the motherboard

I am getting an error msg Invalid AC adapter on my Dell Inspiration 1525 laptop. For Bootup. The ac adapter indicator light is on. The battery does not seem to be charging it is at 82 %. And seem to be...

If the system is not identifying the AC adapter, then the battery charger circuit is disabled. So replacing the battery will not resolve the issue. If the sensing pin in the center of the power connection to the portable is bent or broken, then replace the adapter. Also try a known good Dell Branded AC adapter, if issue still occurs, it will require an motherboard.

I had the battery not recognized on boot up. then

the Dell AC adapter has a sensing pin so the bios can determine the wattage of the adapter. If the system cannot ID the adapter, the battery charger circuit is disabled. You'll need a functional DELL ac adapter to get the battery to charge

Ac adapter does not connect to battery

You either have a faulty ac adapter; a bad power supply in your laptop; a bad battery; or a blown LED indicator light.
1. If the connection is not loose when you plug in your ac adapter try letting the laptop charge for a while. (If you are using the correct ac adapter)
2. Try removing your battery and using the ac adapter. If this works the battery is bad.
3. Try a new ac adapter.
4. Power supply is bad

Dell inspiron 1525 will not charge the battery

This problem has arised because your motherboard hasn't identified your battery. So, this is motherboard problem.
next time when you chat with the dell representatives, tell them that your motherboard is not recognizing your battery. They would arrange a pickup and would have it repaired in their center.
Good luck,

Adapter is plugged in, but not charging for my Dell Inspiron 1526. Any thoughts?

turn on the machine and as soon as you turn on the machine keep on tapping f2 which takes you to BIOS screen, In the system option come to the Battery info and if it is showing battery and shows ac adapter as none it means adapter is faulty if it shows ac adapter type unknown then be prepared to purchase a new system board for your laptop
