I have a Dell Inspiron 1564 laptop that I bought a little more than a year ago. May, 2010 more precisely.
A couple of months ago I got this message when hovering the mouse over the battery icon: (connected, not charging). Also, when I turn the laptop on this message appears in a black screen: AC Adapter not recognized, press F1 to continue, F2 for bott options (Not sure about that one) and F3 for something else. I press F1 and the computer works fine, but the "no charging battery still appears.
1 or 2 weeks ago the battery seemed to come back to life for a short time, and I could test it a bit: I could turn the PC on battery only and it would work fine untill the battery depleted. I could (and can) turn it on with the AC adapter only.
The guys at Dell don't seem too sure about what's happening and I still am not sure if the problem is the battery, the AC adapter, the mother board, the BIOS... (I found these options in the internet).
Thus, I am trying to update my BIOS from A08 to A13 or any other that is newer first before moving on to anything else.
Now the big question is: how do I update the BIOS without a charged battery? The system won't let me do that, but I have my adapter plugged in and it is working (seemingly) fine.
