Question about Computers & Internet

1 Answer

My Dell laptop is powered using the ac adapter without the battery. It worked well, however, it stopped powering on (booting etc). The laptop, when connected to the adapter, has the power light on. When I press the power button, it does not turn on. However, the light is still on. I get no sound when I press the button, no fan, no hard drive. Help! The adapter is not defective and I blew the dust off the laptop.

Most probably is that your MB is fried. The battery does not serves as the power supply, it is also a regulator for the electricity. A small amplitude in electricity and the MB is dead without batt

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.

I can't reset bios password to my dell k137p inspiron 1440?


Unplug everything and remove the battery. Open it and remove the CMOS battery and wait 3 minutes. Boot it up without the CMOS, it should say password disabled, now you can put everything back together.

My dell d610 sometime powers up in to xp then just freeze them sometime just 3 geen lights flash then nothing can you help


If there is a power issue, the first thing we need to determine is if it's the power adapter or the battery. Is there any difference if:

- You boot up with the battery in but the AC adapter not connected?
- You boot up with both the battery and AC adapter connected?
- You boot up with the AC adapter connected but the battery removed?

If different things happen for each of these scenarios, the problem is either a faulty power adapter or battery, depending on which one you can boot up without.

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.

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

Have an inspiron notebook 1150... hasnt been used in a while. Computer will not power on. Charging plug indicator shows it is working, but none of the lights on the front are illuminated. No power at all....


Try pulling the battery and powering it on - could be that. In response to your master reset button question - the answer is no, there is not one for this laptop. It also could be an issue w/ the connector between the power cable and the laptop - also, make sure you're using the proper AC adapter provided by dell when you purchased the laptop.

Hope this helps - good luck!
