Hi i recently bought a 3rd part replacement battery for my DELL inspiron 6400. on installing the battery the computer tells me that it does not recognise the battery and thus will not charge it. Yet it...

First check in BIOS whether the BIOS itself is identifying the battery.Behind the battry there is a health check meter which will tell the current health of the battery which will tell you whether it is time to replace the battery.
also try reinstalling the ACPI chipset driver.

Dell inspiron 6400 Battery problem

what i would suggest is to check the bios there may be a new flash download on the dell website, my wife has a inspiron 1525, which is plugged in and says not charging, the battery will not go above 0%, but we have had to send it to dell (still under warranty) faulty motherboard. if the bios is up to date, there could be a hardware issue with the battery or motherboard

Reset bios password

If you are not afraid to open the box, the simple fix would be to remove the cpu battery(looks like a quarter) for about 30 seconds and replace, then boot up. At that point it will ask for information such as date and time, but then you can access the bios

Very low audio

Hi Sir's / Mam,

In order to resolve your issue you would need to do the following steps:-

1.Update latest BIOS and sound drivers.
link for BIOS update :-

click on this URL and before any steps are done please save your work and also check in BIOS battery charge should be more than 10% in BIOS and Ac Adapter should be connected and make sure that there should be no power failure during this process.

Update the Sound drivers:-

After the BIOS update try to update the sound driver on the link mentioned above.Even after both the updates don't give results call Dell Tech Support and based on the HW warranty get the motherboard replaced.

Also try and connect to external speaker and see if the issue is same or different??
