I recently aquired a Dell E1505 (6400?) Inspiron Laptop computer as part of some work I did for a client. I upgraded it to Windows Vista Ultimate and the installation went fine.
I have no battery with this unit (the client had removed it to use in another similar model he owned) and I just want to run it off the AC (I will buy a battery at a future date).
My problem is that I cannot stop the amber battery light from flashing. I've tried shutting off the power and disconnecting it and sometimes it won't come on for an entire session; most times however it starts to flash after you get the Microsoft Windows screen in DOS.
Any suggestions? I really believe this has to do with the Vista upgrade (I had shut the computer off and it installed about 78 updates automatically); after that the amber light flashed incessantly during the bootup process (it does not flash during the BIOS update - I have revision 17 I think.)
I can cover the LED light with black tape or buy a battery -- but before I spend $99 to $150 I want to see if this has a simple fix first (especially since there appear to be dozens if not hundreds of posts from Dell users with good batteries who still have this issue.)
Again, there is NO battery in the unit and the computer is working fine (diagnostic tests all passed.)
I tried turning off the power settings for the battery notification and also disabled the drivers for ACPI (BattC.sys, etc.) in device manager but this doesn't do anything.
Thank you in advance for any help :)
