Re: battery charging

I have a similar problem. So I ordered a new battery. It charged to full (or so it said so) and to calibrate it I ran it down as directed by HP. It only ran for 30 mins before shutting down. I couldn't get it to recharge to save my life. I decided to put my old battery back in and return the new one. The old battery started to recharge. Wow. It ran about 2 hours (six cell) and stopped charging???? What gives? After returning the 12 cell EBay battery, I got a new replacement (expected refund) and tried to charge the new one. It charged to full and I proceeded to discharge it. It took a long long time. Over 5 or 6 hours (lost track). When it discharged I plugged it back in to charge. It would not charge. Snap. Getting frustrated I started looking on the net again to see if anyone else is having the same problems. Lots! Only none with a solid solution. I have two different charger adapters that work great. I apparently have two batteries that don't work. Makes no since. Randomly, I mean randomly the battery charges whenever it feels like it. Or the laptop is really messed up. I have even downloaded the latest BIOS updates. The old battery started charging, randomly. Still snapping. I've read where some have removed the battery a few times, trying several what seemed like silly things. My motherboard was replaced earlier due to power port damage (kid use). Several have said loose power cord. Lets face it. If the unit powers up then the port should be fine. I decided to try several silly things. Remove battery with power on, with power off. Nothing. I tried doing this several times and it seems endless frustration. Everyone says to buy a new battery. Battery is fine! There is something really squirrelly about this laptop. I had the unit plugged in and decided to see if the contacts engage properly. With the laptop on my lap top, so I can see the battery engaging as I engage/disengage the battery several times while activating the secure battery slider. After 2 mins I noticed my battery randomly charging again!! Double snap! Still don't understand the whole dynamics of the random thing. HP seems to be oblivious and says to buy a new battery. After stating I have a new battery they say to send it to them (ha, or take it somewhere else for no solution, well maybe) If I can't get this to consistantly randomly charge my bad batteries, I'm going to keep being frustrated or buy a different brand with different problems. Buying another new battery will not help, just more frustration.

Re: battery charging

Does the machine boot and work just on AC?

If it does then you may have a bad battery - Does the old battery charge?

If it does not work on AC then try another AC adapter - even the generic universal kits should be enough to test it.

hopefully that's all thats wrong. let us know.

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.

New 6600 mAh battery won't charge

Is the AC adapter the original that came with the laptop or is it a replacement?
Check the label on the laptop (on the bottom of the laptop) for the voltage and current requirements.
Check voltage output of the adapter with a multimeter, this voltage should be slightly higher that the voltage than what is shown on the adapter's label because there is no load on the adapter.
It could be that the current (amps) that the adapter is delivering less power than the laptop's requirements, whilst it can power the laptop it may not be sufficient to charge the battery fully.
Try charging the battery overnight by shutting down the laptop but leaving it connected to the mains. Then boot up the laptop in the morning and check the battery's charge state. If the battery is at or near full capacity, then the problem is a (part) faulty adapter.
