Question about Computers & Internet

4 Answers

Bought new battery for dv9000t but monitor says "Charging, 0% available" And indeed after several hours still no charge. There's probably a trapdoor disconnect as part of the complex electronics inside a Lion battery to prevent charging when cells are out of acceptable parameters. I would not be surprised if there isn't a way to perform a reset from the 6 external pins. Agreed Lion charging is not for the begining level of understanding. Any guru out there on this matter? glibert@cox.net

    Thanks Coolguy, But I think the power adapter is good because the 9v9000t will run OK without any battery . Plus when I did have a moderately good battery (recently) charging was normal. I replaced all the cells in this and that's when my problems started. The new battery I ordered was dead from the getgo.

  • glibert Apr 22, 2008

    I think 3 is the clincher. dv9000t runs just fine with no battery or the dud battery and the blue light on the laptop works. I am going to the battery calibration. Thanks for the help.

  • glibert Apr 22, 2008

    Thanks for the BIOS alert. Actually the m'board was recently changed because plugging in the Ac adapter killed the wireless and bluetooth sub assembly. Hp was kind enough to fix that under guarentee. So I think the bIOS is probably up to date but I will check tomorrow. Regards Gilbert.

    Well! Power Cycling, that's a new wrinkle. And I have just done exactly as you suggest. However I am sorry to report no cigar. So is it charging I hear you ask. Well Vista says 0 percent available, plugged in, charging, Current Power Plan HP recommended. And no there is no plastic on any connector. Voltage measurements on the battery show about a half a volt on the 2 outside pins. When I had a semi-good battery there was about 15 volts there. The SMB circuitry has somehow disconnected the battery from the connector both on the new battery and on the one I changed the cells in. I hoped your power cycle would reset the world, but not yet.

  • glibert Apr 22, 2008

    Yes Thanks we have the latest and greatest HP BIOS F.29 Thank you.

  • glibert Apr 22, 2008

    Yes tried the magic 3 times battery in battery out trick and the restore to no avail. I am pretty sure that the fault lies with the battery itself because 1. the other battery worked till I screwed it up by changing it's cells. 2. There is usually at least 14 volts between the outer pins and this battery has an iffy half a volt. I have got the company to promise to send me a replacement. That will take a week or better so I will be back with you. Thanks for all the help.

  • glibert Apr 24, 2008

    Dear bestdarngood. HP's Driver and Software download page specifically for the dv9000t still lists the F.29 BIOS as being the latest. I will research the F.3D to see if it is available. I think you are right. This battery charging business is a lot more complex than one thinks, and certainly BIOS related with the System Management Bus and some E-Prom in every battery! Thanks for your efforts on this Gilbert. P.S. I do have another battery on the way.

  • glibert Apr 25, 2008

    more expensively said than done! The dv9000t does work just fine on the power supply with or without the battery installed which hardly points the finger at the power supply. I am betting on the battery myself which has not more than about a half a volt between any of the connector sockets. Drilling #60 holes through the plastic ends of the battery itself and measuring directly to it shows a healthy 15.6 volts inside. Whatever piece of silicon controls the charging of the battery must be either not turned on by thhe SMB or is out to lunch! Regards Gilbert.

  • glibert Apr 27, 2008

    OK definately a bum battery. New one works OK. As to the one where I changed out the cells, the fact that I dropped the assembly on the floor must have broken the thermal fuse. This fuse is a 3 terminal device with a rather delicate ceramic core, and although no visible damage, only 2 legs were connected. I shorted the open legs and the battery lit up. I now have a good battery and a working battery with iffy thermal protection so problem solved. I would love to know more about the technicalities of Lion charging but there isn't so much literature out there except Maxim does a full chip. Thanks for the help. Gilbert.

Hi,

The first step you need to do is to power cycle. I.E unplug the adapter, unplug the battery, unplug any devices attached, and cards attached. Press and hold the power button for 20 seconds.(wont show up doing anything).

Than plug the battery and the adapter in and turn the power on.

It should work fine.

Also check the connectors on the battery. Sometimes they are protected with a plastic tape.

Also you may check that when you plugh in the old battery , does it show that it is charging that or not. By this way we can confirm that the motherboard(power supply) is working fine.

Although i feel that the first step should do it for you.

Hope that this resolves the issue you are facing.

All The best

Sammy

There's a chance it's your ac adaptor but a few things you should check first. No sense wasting the money right away.
1)Is the light lit on adaptor?
2)Is your adaptor warm it's plugged in?
3)If you remove the battery does it run with
with the adaptor plugged in?
4)You may need to calibrate the battery.
Go to Help and Support>Power and Battery>Calibrating.
If this fixes your problem please rate as fixed. If you need more help with this, such as not being totally sure it's your adaptor just add a comment and I'll be glad to help you further. Thanks.

    Also try this, sounds crazy but... with the laptop powered up, take the battery out and replace quickly. Do this up to three times each time checking to see if it's charging. Also, do you have auto updates on. If after you check the bios, if that doesn't work, try the battery thing and then try a system restore to before this started happening. This is a very wide spread problem. If you need help with any of this just holler. Thanks.

HP has identified a hardware issue with certain HP Pavilion dv2000/dv6000/dv9000 and Compaq Presario V3000/V6000 series notebook PCs, and has also released a new BIOS for these notebook PCs, version F.39 for dv2000/V3000, and version F.3D for dv6000/dv9000/V6000.

Go here for more info on this
-> http://h10025.www1.hp.com/ewfrf/wc/genericDocument?docname=c01087277&dlc=en&lc=en&cc=us

The following symptoms apply to the dv6000, dv9000 and v6000 series notebooks:

  • The notebook does not detect wireless networks and the wireless adapter is not detected in the Device Manager.
  • There is no video on the computer LCD panel or external monitor.
  • The notebook has no power and no active LEDs.
  • The notebook does not start.
  • The battery charge indicator light does not turn on when the battery is installed and the AC adapter is connected.
  • The notebook issues a single beep during boot indicating no power.
  • The external monitor functions but there is no image on the notebook LCD panel.

So if you go to the link above, you can see that this is a common problem and the first thing you can do is try updating your bios which the link gives you step by step instructions for doing so.

Please let me know if you are confused or need any more help and I would be glad to assist.

Thank you for using Fixya and Good Luck!

Lenovo battery 0% available( plugged in, not charging)


Your battery is probably dead, the only way to fix it is by taking it to a battery repacker (it will cost you more)

or you can simply buy a new one

NEW Battery not properly charging


Batteries have electronics data that software has to get to properly charge it. Newer lithium batteries maybe different. But apparently, you have a work around for a lengthy use of the new battery.

When charging, the message "check battery" appears


There is nothing wrong if you get this message While You Are Talking, Texting or Surfing the Web. If that is when we receive this message means is that you are using more power from the battery than the charger is supplying at that moment. SO the power/battery monitor in the phone thinks that the battery is bad because the battery is not receiving any of the power that is coming in from the charger BECAUSE you are using the phone while you are charging. So you really don't need to worry about it. If you care about the life of your battery; some experts suggest that the best way it charge is with the phone completely turned off. I know many people believe they can't ever possibly survive life with the phone off. Having said that the next best way to charge is with the phone on but not in use. When you use the phone while you are charging you are putting extra strain on the battery and it's charge control/monitor circuits. Hope this solution is helpful for someone.

Hi there. Your problem seems to be the battery. Usually when the battery is at the end of its life the indicator stays at 0%. If you are still unsure you can go to download.com and get free battery testing software. Good luck...

I bought acer aspire AO531h one few months back. For last few weeks its battery not charging.With AC(plugged in),notification icon says"plugged in,charging",however "0% available"even...


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.

What does the flashing red light mean?!?


The flashing red probably means that the charger is working correctly and is indeed charging the batteries. The light should turn green when charging is complete after anything from 1 to 16 hours depending on how this charger works.

Do the following test: Fit the charger with your batteries and connect it to the mains. After 1 hour check if there is a detectable temperature rise in the batteries. You can do this without interrupting the charge cycle by touching the cells with the back of your fingers. If the temperature is still low, let it continue for another 15 hours or so, checking every now & then for any temperature increase. Should the temperature rise more than a few degrees, then stop the charging by removing the charger from the mains. Should the red lamp remain flashing after 16 hours, then I suspect you to have a defective charger.

If the Acer is brand new then it is under warranty. Take it back to where you bought the Acer and get it fixed under warranty. if you attempt to fix it yourself you will most likely void your warranty.

Battery has not been ussed in over a year and now will not recharge


Chances are that the charger is fine....battery is junk. Had the same issue with my kids' Barbie Jeep. Instead of buying a new battery for $60, I used my Sears 12 volt drill/driver battery by locating the positive and negative on the battery and pos neg on the machine. I bought slide on electrical clips from the hardware store and WHAM....worked fine! Actually better because I have 5 Batteries for my drill and with a smart charger, it only takes an hour to charge. They were bombing all over the yard all day! I just had to keep the batteries charging every hour or so.

Yellow / green light will not go off when charging


Its likely the batteries will take at least several hours to fully charge, if not more. NiCad batteries are slow charging and usually need 4-6 hours for a full charge. Keep them on longer or even overnight but make sure you remove them in the morning. You will probably find the light turns green after 4-6 hours of charging. If lights stay yellow and green after 12 hours of charging, it may indicate a fault in the battery itself where it will not accept a charge.
