My laptop shows no battery detected and does not charge .have installed new battery

sounds like battery is not charged. You may have a dead battery and may need a new battery . Or battery needs to be left in laptop with power plugged in to allow it to charge.

you have the wrong battery,

Ted try this once more:

1. turn off the machine.
2. keep pressing the off switch a little longer 3. remove the battery.
4. press the off button for say 15 seconds.
5. re-install battery after a few minutes.
6. connect charger to computer and see if it shows % charge.
7. when it shows 100%disconnect charger and see if the battery still shows 100% If it does you are now reset. IF not,will cross the bridge then.

Is the replacement battery of the same spec? Some inexpensive battery do not have that correct pins to ID the battery. Try to unplug, remove battery read the specs and post. replace battery, could be that it's not in all the way, and reboot. Does it show after a reboot? Is the charge light on? The win 7 OS isn't showing a battery present?

If thelaptop battery is more than 3 - 4 years old then the battery could be worn out.Rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up at all. OR Thebattery shows a 100% charge but when the adapter is disconnected the batterydrops off to zero capacity in a very short time. If the battery drops to anunacceptable charge level then the battery needs to be replaced.

Hope problem solves. Great time

if ur charger is ok then u have need to change ur motherboard

If the battery is not detected in the BIOS (F2 at boot) and doesn't show as charging, then return the battery and get a replacement.

If neither the original battery or the new replacement battery are not detected in the bios a problem with the motherboard may exist. If still under warranty, contact Dell Support for a repair, if not, then you may be investing in a new motherboard

you may need to have that battery charge for a while, until it can be seen at charge level..or simply check the connections to see that there is no junk in the connector..

Lithium Ion batteries aren't something that you can really calibrate unless the laptop has a utility in the bios to do so (ASUS laptops). You either have a motherboard related malfunction in reporting the battery life as you say it does report in another laptop, or you need to update the ACPI driver which you can get from the manufacturer's website.
