McoreD Posted March 18, 2006 Share Posted March 18, 2006 Hey Guys, I recently wiped the Windows XP Home installation that came with the laptop. Then I formatted the hard disk and installed Windows XP Pro with SP2. Since then I am missing the Battery Icon in the Taskbar. Windows XP Pro could not find battery drivers for the laptop. In Device Manager it comes up as Unknown Battery. I have gone through the DELL Driver CDs but couldn't find any specific drivers for batteries. Has anybody had the same problem before? Any ideas would be greatly appreciated. Thanks, McoreD Link to comment Share on other sites More sharing options...

Thanks, McoreD batteries use a generic driver present on all windows cds you shouldnt need anything special from dell and i can tell you that the drivers are present on even server 2003 discs. I wonder why your laptop is doing this because a fresh install of windows shouldnt have this problem. Link to comment Share on other sites More sharing options...
McoreD Posted March 18, 2006 Author Share Posted March 18, 2006 I am wondering that too divertom15. This is a very unfortunate, strange and an irritating problem. If used without AC power, the laptop TURNS OFF (not Shut Down) without warning because there is no Battery meter for Windows to monitor. So Windows and I both don't know when the battery is going to run out. Link to comment Share on other sites More sharing options...
Justin- Posted March 18, 2006 Share Posted March 18, 2006 Was there any chipset/mother board drivers? I'd guess that would fix it. Also, what is your particular make and model? Go to the Dell website and look for new, updated, drivers and install them all (not software, just drivers). Link to comment Share on other sites More sharing options...
McoreD Posted March 18, 2006 Author Share Posted March 18, 2006 That should be a good start StarSabers. I have downloaded the most recent Chipset driver and BIOS update from http://support.dell.com/support/downloads/...&os=WW1&osl=EN# for the DELL Inspiron 9100. It let me install the Chipset driver but didn't let me update BIOS because it thought the Battery is not installed. At the moment I am installing DELL's XP Home Edition on another partition hoping that Windows XP Power Meter will detect the battery on that installation. I will then try updating the BIOS from there. Link to comment Share on other sites More sharing options...

naebarbat Posted April 17, 2008 Share Posted April 17, 2008 I had this problem today so I thought I might as well post the solution.... The error is due to the batt.dll file. It is missing in the windows/system32 folder...download the file from www.dlldump.com/download-dll-files_new.php/dllfiles/B/batt.dll/5.1.2600.2180/download.html ...put it in the system32 folder .....that should take care of the problem! :yes: Link to comment Share on other sites More sharing options...
