On startup, my Dell Studio 1745 told me that the battery experienced a permanent failure. I figured it was just a routine expiration of the battery. I ordered a new battery, attached it, and plugged in my ac adapter (not the source of my problem - I tried an identical replacement). I still get the message on startup before Windows loads that the primary battery cannot be identified. The computer will run on the battery without the charger, and it will also run on the charger without the battery. I have been doing research and a few solutions required an update to the BIOS. I am currently using A03, and I have the setup for A04 saved to my computer. When I try to run it, I get the error that the battery is not for Dell, although it is a Dell battery. If I try to run the BIOS flash without the battery, I get the message that I must have the battery and the adapter attached before flashing the BIOS. I have even tried some so-called, simple "reset trick" by shutting off the computer, removing the battery and the adapter, and pressing and holding the power button for 5-10 seconds. That did not do anything. I have run the diagnostics by pressing f5 instead of f1 on the message screen about the battery not being identified, and nothing came up. Technical support for Dell just suggested I try to get my computer repaired because it may either be my motherboard or "charger board," and I highly doubt that because I have not even used the laptop after March 2010 until three years later, and only briefly. I bought the computer at the end of 2009. My warranty has expired, and Technical Support told me my computer has "reached the end of its life." Apparently computers are not designed to last for more than a few years? I have basically no confidence in Dell Technical Support.


If I do need a repair, what might the problem be and what can I expect to pay?


I have tried reinstalling Windows, I don't think I'm missing any drivers - my device properties shows no "!" 's. Is there a battery driver I need? I seem to have a faint recollection of seeing a 'Dell Composite Battery' driver somewhere while reinstalling drivers, but nothing like that shows up when I enter my service tag on the Dell support webpage and view the relevant drivers.


Again, the battery and/or the adapter are ruled out as the issue.


The tray at the bottom right of my desktop says 61% available (plugged in, not charging).

Hello, and Welcome


People have reported success using the forceit switch at the command prompt. Also, after the BIOS update, the battery started charging again. Type cmd, right click and run as administrator. Your adapter should be plugged in and battery installed.


WARNING: a bad flash could brick your computer.




Read through this Dell thread.


If you would like to see your battery ID type and charging capacity close all programs and type cmd at the search box, right click run as administrator and type

powercfg -energy -output c:\energy.html

After about 60 seconds a report will be generated. Double click the C:\energy,html file
