Battery Won't Calibrate nor Hold Charge

I am using a Pavilion ze4145 laptop that was bought a few years ago. It was a friend of mine who gave it to me and said I could keep it if I could fix it, and get his data off of it. After solving several problems with the fan, ac cord, and BIOS, I was able to get the thing going.

However, the battery will not hold a charge and the status light is blinking amber. I went troubleshooting and tried everything the HP website had to offer. Nothing has worked. When I calibrate the battery, it takes only a few minutes when it should be taking several hours. I figure that it just won't hold a charge. It is a Lithium Ion battery so it shouldn't have the memory effect.

I don't know much about how the guy treated this computer before I got it, but am certain that even though he doesn't know much, he took the best care possible.

I am not looking to buy a new battery, but will if I need to, and if it's certain that the battery is the problem. Battery icon shows 0% but when the adaptor is plugged in it shows its "plugged in and charging" but battery doesn't charge. 0% still shows for battery. When I unplug the AC adaptor laptop goes dead.

I did not take any troubleshooting steps. I don't know what to do. Need help please.

TRY PUTTING THE BATTERY IN A ZIPLOC BAG AND LEAVE IN THE FREEZER OVER NIGHT. THE NEXT DAY TAKE IT OUT & LET IT WARM TO ROOM TEMP, WIPING OFF ANY CONDENSATION. THIS MAY PERMIT IT TO CHARGE. THIS IS A DESIGN PROBLEM WITH THE BATTERIES THAT ACER BUYS FROM WHOEVER (MAYBE FROM CHINA??), WHICH ALLOWS THE BATTERY TO SELF-DISCHARGE ALL THE WAY WHEN IT SITS FOR A WHILE.

I DON'T KNOW WHY THE FREEZER TREATMENT WORKS BUT IT DOES. I DO KNOW THAT FREEZING RE-CHARGEABLE BATTERIES THAT ARE ALREADY FULLY CHARGED ENABLES THEM TO HOLD THE CHARGE A LONG TIME - I DO THIS ALL THE TIME WITH NICADS, NICKEL-METAL HYDRIDES, ETC.

HOPE THIS HELPS & APPARENTLY WE NEED TO LEAVE THESE THINGS ON CHARGE ALL THE TIME. :-(

That is normal, when Lithiumbattery is faulty, charger light stays on and battery does not charge, and stay 0% or low charge.
You have a useless faulty battery, when charger contacts are defective you do not get charging light.
You need to buy a new battery, this is not an expensive part:

You get it here for $66

    The battery for mine is an exspensive part, (£240) so the above comment is not strictly true.

Very poor battery life, have to keep it plugged into mains almost all the time. This is after less than 3 years old, probably nearer 2.


Hello there,

Yes my dear friend, the battery is bad already that is why it seems like you have to get it plugged into the mains all the time when you are using the laptop.

The battery tends to last for over three years, but there are some things that gets to drain the life cycle of the battery.

Things like, plugging the laptop when ever it is in use. Once the battery is full, one needs to get it unplug it from the mains and use the battery till it is low before connecting the charger back on it. That way, the battery will last a while before the cells die off. As constant charge gets to weaken the battery cells and therefore makes the battery weak and unable to hold a charge.

The battery can also get bad if the voltage used to charge it is very high. High voltage tends to kill the battery cells also.

Some times, the battery could last for over three years and at times less that. The cells in the battery could get weak at any time. So I will advice you get another battery and this time, take caution on how you get to charge the battery.

Hope this was helpful to you.
Goodluck

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.

My HP dv4030us is about six years old. I use it, primarily as a desk top, so it is always plugged in to AC. I perodically used the battery, but after 6 years, it would not hold a charge. I bought a...


I had a similar problem with my Acer Aspire after I got a replacement battery about 6 months ago.
I was told to disconnect the laptop, turn it off, disconnect the battery, then press the power button for 30 seconds to reset the charging circuit.

I did this, but it didn't work any better. I thought that since my charger seems to run the computer, but it says 0% Available (plugged in, charging) that there was something wrong with the battery.

So, I contacted the manufacturer of the battery and they said they would refund my money within 7 days after receipt, and they gave me an RMA number for the return on the address label.

I, also, got the battery from Ebay.
---
Since your problem is that the battery icon with a red X over it says 0%, I would say that maybe the battery is bad, or maybe the battery is not connected very well at the contacts. Maybe blow the contacts off with compressed air in order to clean any dust which may be on it.

I would maybe try another battery to try to see if the charging circuit is bad on the laptop.

If another battery doesn't work, then the charging circuit between the laptop and the battery may be faulty.

Good luck on this repair.

The charger is on but the charging indicater light is not on


You probably need a new battery. A laptop battery loses about 20% of it charge ability each year and this seems like an older laptop. The break down because the heat generated by the laptop effects the battery's chemical behavior. Try ebay for a new replacement.
