Hello, I got a Presario 700 Compaq laptop, And for some reason my battery will not charge, Last night it charged the battery and it was good, but everyime I put the battery back in it wont charge.

U may have a dead board. They average $285 plus labor. A shop should be able to test it on a volt meter see if the power grid is burnt for around $35. then u will know what ur in for. If its a bad board just replace the laptop I wouldnt repair that problem on an older laptop.

Motherboard is dead...

let the battery completely discharge, then fully recharge. Do this at lease two. After it has fully charge the last time, see how long it takes to disgharge. It should be somewhat better. If that does not work your battery is shot and needs replacing.

It could be the battery needs replacing ... it shows that the battery is charging but it doesn't keep the charge .....

try to turn on the laptop without the battery and only the power cord plug in.

if your laptop works with this you need new battery or update bios ( there might be fix for battery monitor)

if not, call service support, might be motherboard issue

let me know an update

red light = 25%
Red + Green = 50%
Red + Green + Green = 75%
Red + Green + Green + Green = 100%

u can take care of ur laptop by conceedaring below points like.....
1. always use a good and updated antivirus.
2. avoid with shokes means carry with care.
3. important for battery ........
full cahrge the battery and after complete discharge charge again . never keep ur battery pluged with power cable . it will increase the battery life and backup....

No the battery does not have to be in for the notebook to work. No the battery does not have to be charge for the notebook to work. It sounds like you have a AC jack issue. Check to see if the AC is loose. You need to get this repaired by a local notebook repair shop.

I hope this helps. Please rate.

I had a similar issue with the Armada M700 from Compaq. Never did figure it out exactly. But I do know this. When you unplug the power chord and take out the battery and plug the power chord back in while the battery is out usually for some reason it turned on allowing me to replace the battery which would then begin charging. Your problem interests me because I can really relate!

When you install a new battery and remove a battery always make sure the laptop is completely shut off and have the power cord removed so that you avoid any possible power surge.

Batteries generally don't last much longer than a year and I have found removing the power cord or battery when it is off to be a good practice.

Before you charge a battery make sure it is run most all the way down. Recharging a battery when it is not run down can give it a memory and you may only be able to charge it up to the point you started charging it.

Anyway, if the computer won't charge a new battery then you could have a bad motherboard. To be sure try another battery.
