Battery not detected

Hi.

I've been using this Dell Vostro 1700 for an year. Now I face a problem with the battery. For the last couple of days I've been warned that the battery is reaching the end of life although it is charging normally. Now I see a wierd message in the system tray. I see a battery charging icon with a cross mark on it saying "No battery is detected".  If I remove the power cord, the laptop does not shutdown. It continues to use battery power. So I see that the battery is being used, though it is not being detected!

I've seen a couple of people discussing on the same problem, but I couldnt figure out any specific solution. Did any of you figure out the root cause or a solution to this?

Thank you!

Re: Battery not detected

Check the contacts on the battery to be sure they're clean.  If they are, you've got two possibilities:  the battery is faulty, or the mainboard is faulty.  Since the battery costs $150, while a mainboard is $400+, try the  battery first.

Re: Battery not detected

I had a new motherboard installed yesterday (because the battery wasn't charging, but showed 'good health' in the BIOS).  The new motherboard is using A8 BIOS instead of A12 (previous).  It now detects no battery at all.  I checked the battery , cleaned it and there's no corrosion.  What could cause this problem?

The battery is dead - replace it.

Re: Battery not detected

Hi, I have a similar problem. I have Dell Precision, it used to provide over two hours backup. Suddenly one day it went down. And in a day or two saying no battery detected and not offering any battery backup.

I purchased a new battery that worked fine for two months and then one day encountered the same problem.Just for a test I used my first faulty battery and amazingly it worked fine as a new one. But after few days of usage, again same problem. This time Dell doesn't detect the battery, but when I unplug, battery works sometime for more than 1 hour and sometimes goes down suddenly.

I thought it only problem with my laptop, but two of my colleagues having similar problem with Dell laptops(different models). All of us are using Windows Vista on Dell Laptops.

I am using Dell laptops since 1998 and never used any other brand after that.

I believe Dell should look into this matter on very urgent basis.

I live in Pakistan and very willing to offer my laptop with both batteries for examination to Dell.

Thank you.

Re: Battery not detected

I just had the same icon appear on my laptop --- I went to the Dell Support 'Drivers and Downloads' page and (with the correct laptop and OS selected - it selected them automatically for me) I selected 'Bios' and downloaded A15.  After it installed and restarted, my battery was detected again like normal.  Try that if you're not sure that you have A15.

Re: Battery not detected

How did you install the BIOS update with the "No battery is detected" warning? My computer just tells me "The AC adapter and battery must be plugged in before the system BIOS can be flashed. Press OK when they are both plugged in or CANCEL to quit."

Re: Battery not detected

I didn't get that error message -- I would look for another way to update BIOS first, but if there's no way to do it I would guess that the actual battery and/or the adapter is damaged.

Re: Battery not detected

Okay, it started recognizing my battery so I flashed the BIOS, but the problem came back. I decided to download some better diagnostic tools and this is what I found out: Usually, my CPU's clock multiplier is set at 9.5. When it slows down, though, the clock multiplier changes to 1 or 1.5! I'm currently trying to figure out how to either set it static or increase it once it goes down.

Re: Battery not detected

Hello Inspiron 1545 2.53 GHz.

I am having exactly the same problem.

How did you flash your BIOS?

Thanks
