Compaq nx 9030 battery does not charge

Dear Sir

all over sudden, my compaq nx9030 battery will not take any charge, I have checked the adaptor, it seems to be ok and gives 18.5 V.
My guess is either the battery is damaged completly or the charging circuit inside the lap top is out of order, I have tried some software called battery doubler, still the same thing,could you please help me out , how to measure the battery output? and how to measure the output voltage at the connector inside the laptop for charging the battery?

thankyou in advace

Please i want a mobile graphic adapter for games on my hp compaq nx 9030 window 7

No such thing. The performance would be awful via the USB 2 port. Compared to a PCI-X card.

Pls i have a hp compaq nx 9030 when i press the power butten the blue I/O light blinks but the system does not on what do i do or what is the problem

I suggest to try removing the battery and get it back and start again ..If it crashed and turned off it may need to be disconnected from all power before starting again ..Or the battery may be in short and conflict with the ac ..try to boot up with the ac power alone ..
The blue light is not usually a fault ....when the board is damaged the light is usually amber..

Sitting of dato and kl

If the date and clock is not keeping your settings to blame is the bios battery ..and need to be changed..The battery is usually on he main board just under the keyboard..and the wireless card ..and can be accessed from the front if you remove the hinges cover..than all the screws of the keyboard ..slide the keyboard toward the display for an inch and lift it ..Unplug it from the ribbon ..and you will have the wireless card exposed..You have to remove this card also and you will see the battery ..
it is possible to not be able to remove it ..and have to open it in half to get to the motherboard do that you have to remove all from it ..including disk drive ..battery and hard disk ...and all teh screws for to open it in half ..
or ..for most compaq model the battery is accessible from the back ..
take a look on these videos ..
here are 3 different situations ..try to see if your model have access from the back to the battery ..if not have to strip the front and see if there is access under the keyboard..

Battery will not charge compaq presario v5000

I would try replacing your ac/adaptor (power plug) before troubleshooting any further. It sounds as if the adaptor is faulty. Check eBay, you can get a replacement for less than 10 dollars.
