No battery is detected

[unlockAVSO]

I have Dell Latitude D630 Laptop and my battery works fine but in the screen it says that no battery is detected,it was working but when i was working on my laptop the battery place it was overheated (mabye going in 50+ C ),so I removed it immediately and hours later I put in but it says no battery is detected.All drivers are update.What should I do,thanks.

50c isnt hot, so i wouldnt worry, leave it in a car in the summer and it will easily beat that.
Check the pins on the battery as well as the laptop to see if any are bent. one of the pins will be used to measure voltage from the battery to the mobo, if its bent it may cause this issue as its not detecting any voltage.

If it will run on battery, leave it on until the battery runs down and it powers off. Next, plug it into the charger and leave it for at least 24 hours without powering it on.

50 c+ (i think it was) if at your lap top is normal at mine not and it was increasing,i tried all all of them but didnt work
and another question why does my laptop battery runs out so fast for 3-5 mins :O , thanks

oh well thats solved it. your battery is knackered.
its because you leave the laptop plugged in for very long periods of time/overnight.

Batteries have limited charge cycles (normally 1000 charges).

if you leave it plugged in when it gets to 100% it will stop charging, then the battery will naturally very slowly go flat, when the battery looses 1% your laptop will start charging it again, this is 1 charge cycle. they soon add up and beforw you know it your battery is knackered.

to condition a battery properly charge it to 100% and then unplug it, use it as normal and only recharge it at less than 20%. also never leave it charging over night when not on.
if you plan to use it all day in the same spot, take the battery out and just run it on mains.

Basically you need a new battery

no it did not solve,because even that my battery runs so fast the icon was not like that "battery is not detected",It is not a big problem but i would like to solve it,thanks

Do you mean the battery power runs down fast? If so then I suspect it is a bad battery, OR, the battery you have is a replacement?

Read the topic up it's hard for me to explain in english,I removed my battery while laptop was working (it was charging) and you know the icon at the start taskbar which tells you about the battery now it shows only there is no battery detected.

 

[Britton30]

I understood that, but asked you for more info trying to help. Is it the same battery that was in the laptop when new?

 

[unlockAVSO]

yes it is the same battery

 

[badger906]

you need a new battery. thats the only answer. the fact it only lasts 5 mins is a classic example of a dying battery. the fact its not detected is probably because each cell has dropped below 3.3v.

lithium ion batteries dont loose voltage in the same way as a Nimh or Nicad battery does, they maintain the same voltage until they are flat, and then go off slightly.
If the voltage drops too low it can do irraversable damage to the cells. and I think what has happened here is that the cells have dropped below the threshold and is no longer detected by the motherboard as its looking for more than 3.3v per cell.

The machine isn't offered by Dell anymore, so it could be a weak or dead battery - they only last a few years.
The Dell links above will help you determine the condition of your battery. If you need to replace it, you'll know for certain. If it's something else... you can rule out a bad battery.

A replacement battery is not that expensive, but if you don't need to replace it, don't.
