Hi, I am having trouble with my hp omnibook. It cannot run on the battery, it only runs on the power cord. I had every intention on getting a new battery, but while i was looking someone told me you can test some with a button on the side. i tried it and it said it was fully charged. I looked it up in the power management section of the computer (stupid me didn't think to check it before) and it said the attery was fully charged, i took it out for about 10 minutes and put it back in, and it said it was 24% charged and then charged to 100% in about 5 minutes. I thought that was weird. Can anyone help me???

Your battery has developed what is commonly known as the 'memory effect'.
Basically this means that your battery is giving false readings due to it's bad health. The battery is dead and must now be replaced.
Rechargable batteries require quite careful looking after. Keeping them on charge all the time or regular recharing is NOT good for them. They MUST be regularly discharged too in order for the batteries to get what you could describe as 'exercise' for the battery.
If you just charge, charge, charge then it will eventuallyu develop the memory effect and kill the battery. If you allow it to discharge regularly then the battery will last a lot longer.
Think of it like a person. If you continue to feed someone and they don't exercise (I'm talking about 24/7 couch potatoes) then eventually they are likely to have a heart attack. Some mild exercise will keep the persons heart healthier - even if it's only walking to the local shop or mowing the lawn.

There are two possibilities here.
1. The regulator which charges is not working correctly to charge the battery, thus saying it is full not 24% charged. You probably need to charge out the regulator.
2. The battery is not good and needs to be replaced.
I am 95% sure it is the regulator.

Your battery has an internal short. Don't believe the idiot lights. Get a new battery if running on battery is important to you.

use a multi reader or go to a radio shack or similar and have them test the battery sounds like a false positive
