Yeah man, you were so rude almost three years ago. Makes me sick. I sure am glad I got an email today alerting me to your rudeness, thanks HWilliams1970. Thankfully I just sit around sans-pants instead of working, responding to rudies like you on posts that were made in 2011 when I did have something better to do. OMG soooooo RUDE!
If your battery is not recognized by the computer the most common issue is the battery itself. I noticed the other day that mine wasn't charging. It said at 95% plugged in and not charging. there is nothing in the software to fix this, it's not a driver, it is in the bios. 99% of the time it's a battery and the only way to test it is to replace it. So, Jim here had it right. If you buy a battery online, check the return policy first so if that doesn't fix the problem for you, you can return it and you're only out the shipping charge.
my dell insp 3421 laptop battery is not detected . I change battery charger and i installed win 7 64 bit but problem is not solve what i do ?
read the post directly above your post. The new batteries have a chip in it that detects it is wearing out and stop telling the laptop that it's there. So your 4 hour battery doesn't go to 3 and then 2 hours, it becomes worthless according to what I have found online.
I had the same problem just now. I tried this one out. it worked with me !! I just do as this; "Please remove the battery and ac adaptor. Then press and hold the power button for 15 seconds. Now wait for 2 minutes. Please reconnect the battery and ac adaptor and power on the system." now it come back to normal. thanks !!!
