    This really depends on what percentage the battery is stuck on and how long it takes to use up the battery. I have an older laptop that the battery is more or less stuck at 98-99%. It will not hit 100% unless I recalibrate the battery. Some batteries have a onboard controller that acts as a battery management system and needs to be recalibrated as the battery gets older. This is found on some HP and Compaq models. If it is stuck lower than nearly full that is a bad battery or one not wanting to take a charge which is not good. You need to replace the battery as soon as you can or if you model support it run on the charger with the battery out of the case. Usually even a bad battery slowly takes a charge but quickly looses it. When it won't take a charge as yours is doing it can overheat and the battery pack can rupture or even catch fire. This has happened on new as well as older battery packs on various manufacturers makes and models. Even if it doesn't the battery does need to be replaced. Replacement cost should be about $65 to $80.

It is not your charger. If the charger had a problem (rather rare) it would not provide enough power to run the laptop at all. The way those fail is totally at about 99.99% of the time.

Your symptoms are typical of a bad battery. It probably has 2 or more bad cells inside for it to stay that low. As I mentioned when you try to charge them and the cells are damaged they will overheat which can cause more damge both to the battery and the rest of the laptop It can also be a bad battery mangement controller. This just monitors the battery charge state. They can loose thier stored settings Once this happens it doesn't know where 100% is. The battery in the DV6XXX series do not have a reset or user calibration option.

So the simple test here to figure out if it is the battery is to charge it as high as it will go. When it reaches as high as it will go then pull the charger out and run the laptop on the battery. If the run time is short before the battery warning comes on then the battery has bad cells and needs to be replaced. If you see more of a normal runtime of about 2.5-3 hours then the battery is fine but the battery manger is the problem. If thats the case then you can either replace the battery or learn to ignore the charge display and go by time used or watch for the low battery alarms.

This is typical of a battery with 2 or more failed cells. Best advice is replace it. A new battery is worth about $65 for that model.

It could just be that the battery is not holding charge like it used to, due to age possibly. Either that or the computer isn't reading the charge right. Run the laptop on battery power to figure out if the battery's capacity is dimenished. You could have a slight problem with your charger. Measure the output with a voltmeter. Usually, however, power supplies just die. That's about all I can think of, hope it helps.

My laptop is not charging. it says 0% available (plugged in, not charging) plz help i have a stock hp pavilion dv5


Ifthe laptop battery is more than 3 - 4 years old then the battery could be wornout. Rechargeable batteries have a finite number of charge and discharge cyclesand will lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up atall. ORThe battery shows a 100% charge but when the adapter is disconnected thebattery drops off to zero capacity in a very short time. Ifthe battery drops to an unacceptable charge level then the battery needs to bereplaced.

Hp dv5 charger port seems to have u loose connection. if i wiggle the plug i can get it to charge sometimes. what do i do? is this something that can be fixed?


You need to diagnose first if the problem is the charger or the port of the laptop itself if it is possible to try a different charger to check if the cause of the problem is the charger if not then what i suggest is for you to check if you still have a warranty for your HP laptop so that you can bring it to the repair center free of cost because it might be the motherboard that it is causing the problem

Problem with your charger, try this :

1. Check whether the charger plug is properly inserted in the Power port/jack of your Laptop!

2. Check the power cord (any cuts OR torn-out)!

3. If above steps don't work, replace your charger.
