When I plug in my Dell Inspiron 1521 laptop, I get an error message saying it does not recognize my charger, will not charge and will likely slow down my computer's speed/performance. Everything...


Same topic on Dell official community, may it will help.
http://en.community.dell.com/support-forums/laptop/f/3518/t/7311465.aspx

There is high possibility that your adapter is stuffed. Dell have built in a recognition circuitry into the 65w adapters and when that goes, the system will no longer recognize it as a 65w adapter even though it is still putting out 65w. The system then shuts off the battery recharge circuit and to make matters worse it won't even charge the battery when the computer is off. It also speedsteps the processor down to half its speed so everything runs slower. Only option is to stick with a slow computer that can't be used on batteries or buy another ac adapter.

If you do not want to pay $80 for a original adapter directly from dell, there is an alternative choice to get an 3rd party charger, check this link below:

Tip

Battery won?t charge and AC adaptor not recognized


I have a Dell Inspiron 6000 that just turned two years old.

After one year, my dell 6-cell battery started to falter, so Ipurchased a new 9-cell battery. This worked fine until a couple ofmonths ago when I noticed that my 65W adaptor was frayed. I bought anew 65W Dell Inspiron 6000 ac adapter andit worked well for about a week until I noticed that my battery wasn’tcharging at times. If I was patient, or unplugged the adapter andplugged it back in, the battery began charging and all was saved.

This lasted only a short time until my Dell Inspiron 6000 batterywouldn’t charge at all for long periods of time, and sometimes thecomputer wouldn’t turn on, even if plugged into the wall. I thought itmight still be the adaptor, so I borrowed a fully functioning 90W Delladapter from a family member to test the system. This worked better,but still not great.

When I removed the battery and started only fromAC power, the functionality was also intermittent. Usually, if thecomputer actually started, I received the start-up error “The Inspiron 6000 AC AdapterType could not be determined, etc. etc. etc.” After pressing F1, thecomputer booted, but if the battery wasn’t in, the computer didn’tusually last long before shutting off. Unsure if maybe the battery wasthe problem, I put the 6-cell Inspiron 6000 batteryback in, and it too wouldn’t charge, although (together with the 90Wadapter) my computer would at least start more consistently if pluggedin. The error remained however, and sometimes the system stopsrecognizing power and switches to my ever dwindling battery power untilthe adapter is recognized again.

The problem is with the jack on the motherboard inside our Inspiron 6000’s. This is the jack you plug your power plug into on the back of the laptop.

Somehow the jack gets worn and does not make correct contact withthe laptop so the Laptop does not see the power supply as a legit Dellbrand. So the powersupply will not charge the laptop battery and run the laptop at the same time.

DC power jack repair guide. Do-it-yourself instructions.

Modern laptops are all sold with built-in wireless laptop ac adapter.Some power notebooks used by corporate road warriors will have powerfulcellular adapters that connect the laptop to the Internet via the cellphone infrastructure

A bad connection between DC-IN power jack on the system board and the system board is a very common problem with dell pa 12,dell e1505 and Dell Inspiron 6000notebooks. If your laptop is out of warranty, then you can fix theproblem by resoldering DC-IN jack on the system board. If it’s stillunder warranty, it would be fixed at no charge to you. Problem symptoms:

  • Laptop randomly shuts down without any warning.
  • Power LED and battery charge LED start flickering when you wigglethe power cord or the AC adapter tip on the back or your laptop.
  • The battery will not get charged.
  • When you plug ac adapter for laptop, the laptop appears to be dead and there is no LED * activity at all (DC-IN jack on the system board is broken).
To fix the problem, you have to take your laptop apart, remove the system board to resoleder or replace the DC-IN jack. dell pa 12 and Dell Inspiron 6000 disassembly guides will help you to remove the system board. Take a closer look at the power jack on the system laptop board witha magnifying glass. In most cases you get the power problem because ofa bad connection between the DC jack and the system board, you’ll see acrack between the DC jack connector and the system board.

The adapter could be faulty or has failed slightly and is below the operating limits. This means you probably need to replace the power adapter.

Wireless internet dell inspiron 6400


Things you can do to try and improve the connectivity are:
1. Update the system BIOS to the latest version
2. Update the wireless driver to the latest version (Both are available at support.dell.com)
3. Try a different channel for wireless on your router (Most default to channel 6, so try 1 or 11)
