Laptop not charging the battery

Okay guys, I got a tuff one. I have been trying to figure this problem out for over 5 months now without resorting to replacing the motherboard. I realize that this is probably the most likely answer to the problem, but I am hopeing that someone out there knows a quickfix to this.

I have an HP DV9600 Laptop. One day it stops charging the battery. Ironically, at the same time, the AC jack seemed to be coming loose beucase it would not stay seated in place and made moving around with the laptop near impossible. After going to the HP website and downloading the calibration tool, updating my bios, I decide it is probably a bad connection of some sort with the power port, so I replace the module but it still feels loose and it still does not stay in place. I come to the conclusion that the problem is the power cord. The tip of the plug is tweeked which is giving it a bad connection. I use a different power cord and it stays in place and I dont have any problems using the laptop anymore, HOWEVER, the battery still does not charge anymore. I replaced the battery from another laptop identical to my DV9000 and that battery does not charge in my laptop. So I took my battery and tried it in the other laptop and it works fine(although very low on power). So I come to the conclusion that there is a problem with the power relating to the battery port.

The obvious remedy to this problem is to replace the motherboard, however, like I said, I am hopeing that someone out there has an alternative such as checking to make sure the BIOS battery didnt die(I havent tried this yet, I will though if someone thinks it is worth taking the entire laptop apart to find out).

    I tried another charger. It works fine for just direct power, however it does not charge the battery. I tried another battery with the new charger. It does not charge it. The problem is not in the battery or the charger, it is something in the laptop. Since I already replaced the power plug, it is probably something in the motherboard. The question is...what part of the motherboard and do I need to replace the motherboard to get the laptop to work properly or is there a trick that will allow me to get it to work again. I am out of ideas. I have been banging my head against the wall trying to think of some explination as to why it is not working. I know that sometimes boards fry or whatever, however, I already looked at the motherboard thuroughly, I didnt see a single flaw on the PVC or the circuity. I already did a BIOS update. Like I said, I am out of ideas. If you have anything for me to try, I will do it, but I am not sure what else to do other than trying to see if it is the motherboard/bios/cmos battery.

    This didnt solve the problem, but your info on the battery part was very helpful so I gave an approprite rating.

    I sent it back to HP for repairs, they have a service enhancement going out. Thanks for your help.

If your internal BIOS battery is flat it would not cause such malfunction.That would give us some info if you could try the other identical laptops charger on your laptop to find out exactly what is wrong.If your laptop wont take the charge even from the other charger then it means there is wrong inside your laptop.
You can try to dismantle the device carefully ,you may discover a faulty connection.Try to look for the connection close to the battery.

It sounds more like your charger is the problem.... Btw,the cmos battery stays charged for a couple of years. you will notice its dead when booting up your pc loads default settings on in your bios...i.e the time resets each time.

Dear power cord is use for charging your laptop battery so if you don't use power cord then you will be unable to charge your laptop battery. But this is truth that if your battery charge is okay then no need power cord but tell me bro how can you charge your laptop battery without power cord. This is totally funny. Yes one way, that is you can charge your battery by using dc adapter. But if you do it i am saying you that you just going to spoil your laptop and also battery.

If unused for any length of time, rechargeable batteries lose their ability to retain a charge. Try it with a brand new, fully-charged battery. FWIW, I recharge all my camera and flashgun batteries monthly.

Acer Aspire 5738Z won't hold charge


Sorry. It seems that your battery is dead.
If your laptop is working fine on AC power only (with the battery disconnected), then your battery will need to be replaced.

The third light from the left is flashing brown instead of green. But laptop is fully working


Sounds like your battery is getting old. I had the same thing happen to me on my Dell Inspiron 220 I bought in late 2005. After 4 years the laptop battery wouldn't take a charge, blinked a brown LED, and would shutdown the laptop if I unplugged it. I went to comptick.com cuz of the low prices and searched by my Laptop Model, TYPE and Capacity rating of the current battery. I have a Li-ion. I found a physically comparable Li-ion that had more capacity Wh. I did a search on forums about 9V vs 14V and found out it was okay to use the higher voltage battery without any harm to my laptop.
I received the new battery within a week, charged it up the recommended time before using it, and it still works fine over a year later. Lasts longer too. My wife's 2005 laptop battery died about a month later and I got her's replaced from comptick.com too.

Sounds to me like the transformer circuit that enables the batery to charge. If you have bought your machine within the last 12 months it should still be covered by warranty so go back to the supplier. If not covered I wouod still try as it is not beyond reasonable expecations that the machine will operate perfectly in very way for more than 1 year.

Laptop not charging the battery


yeah, u tried all the thing which a layman could have done, r u familiar with the use of multimeter??

if so plz, open up the other laptop carefully, switch it on!!

with use of multimeter check the current, n voltage at the battery port.

then do the same with ur lappy.

repeat the thing for 2- times.


if both the reading r same ur battery will be charging but the there a BIOS fault, which can be fixed with little help from techincal support.

n plz tell the does ur lappy run if a charged battery is placed??


as u said the I guess the problem lies inbetween ur lappy n the motherboard.



if the readings r different, then maybe ur charging unit is damaged, kindlly replace it !!

all the best, thank u!!


plz take precautions n a well calibratied multimeter !!

thank u !!

if my solution is appropriate the plz vote me.. thank u!!

Battery not getting charged-power supply on ac power


hi thanks for using fixya!!

Is your laptop is brand new? Try to remove the battery. Then, try using your laptop and AC adapter without the battery, you will get the power supply directily from AC adapter. If it works properly, then its okay. Now, try to install back your battery then try to charge it. If not charging, perhaps you need to buy a new battery. However, I suggest you bring your laptop to a service technician to further check the error, before you purchase a new battery.

If you need further assistance, let me know!

I charged the battery all night but it still does not run. The radio works but the rest does not. Please help.


If your power wheels batteries have sat without a charge for more than a few months then they may not come back to life.
I would contact the guys at this website http://www.shopjandl.com/kids---baby-ride-on-toys-power-wheels.html.
Usually the radio has a seperate battery which is not connected to the main battery.
Hope this helps
