Dell Studio 1555 Battery Failure

Hi,

The problem could be with the battery, Motherboard or the AC Adpt for that matter.

You can check one thing.

Go into BIOS (Keep tapping F2 when u start the system)

The BIOS Screen will look like this

Check the AC Adapter Type.

What does it say ?

Thanks for the reply.

It says "90W".

If it says 90W, which means that there is nothing wrong with your Motherboard or AC Adpt.

Try updating the application 'QuickSet' on your system.

Follow these steps :

1) Go to Add/Remove programs, uninstall QuickSet. Restart your system.

2) Go to support site for Studio 1555 applications. Click here to go there now. (Make sure you choose the correct OS)

3) Install QuickSet and restart the system.

4) Even after reinstalling if you face the same problem, Update BIOS from the same link.

5) If still the problem persists, i am afraid you mite have to buy a new battery.

Hi

I have the same problem (adapter connected but battery won't charge, but when I go into BIOS, against AC Adapter Type it says "Unknown device installed". I also get an error message at startup saying it doesn't recognise the AC adapter. This has only happened since I took it back to the shop (with the battery problem) and they tested it with a different power adapter. Do you have any suggestions?

It is 2 years old and I have extended warranty but that doesn't cover battery or cords!

Thanks

Try another Dell adapter - if it doesn't solve the problem, then your system needs a mainboard repair or replacement.

What should i do if it says 65W?

What should i do if it says 65W?

You need to re-install the 'Quick Set' application on your system and it shall work fine. Detecting 65W in BIOS means there is nothing wrong with the Adapter and its a software problem

I can't find the right quick set program, can you help me?

That means the system doesn't recognize the adapter -- is it a Dell adapter or a third-party adapter?

I bought this battery from ebay, so probably it counts as a third-party.right?

The battery isn't the issue - not the primary one anyway.  If the system doesn't recognize the AC adapter, the battery won't charge.  Try another Dell (NOT third party) adapter first.  If that doesn't get the adapter recognized, replace the DC jack:

and if that doesn't do it, replace the mainboard.

The battery may or may not be an issue, but until you have a recognized AC adapter, you won't know.

Thanks a lot for the help. I will try it
