The AC adapter and battery must be pluged in before the system BIOS can be flashed.

Press OK when they are both plugged in or CANCEL to quit.

Is the battery, dead or not, plugged into the laptop? If it is and you still get the message then your only recourse may be to purchase (or borrow) a working battery.

Just one question are you updating the BIOS for any particular reason? If it ain't broke don't fix it :)
Unless there's a requirement to update the BIOS there's really no need.

The machine is old and had (5) Bios Updates.

A17 is the most recent so that's what the machine needs.

This may be why a battery must be connected.

Fixes/Enhancements
------------------
(1) Change pre-charge time out from 2hr to 6hr.

All Bios Updates should be applied immediately as an Update fixes things not specifically called out in the description of the Update.

Many Builder Machines MBs get +15 Bios Updates before end of life.

Most OEM Machines get far fewer less Bios Updates so they are important.

Depends what version BIOS and O/S is currently installed.
I have rev. A16 on my Dell 1525 with win7 and see no reason to upgrade.
Need to look at the changes between each rev. then decide if you need to upgrade.

EDIT: The reason they want both the battery and power is in case of a power blip during the BIOS update.
Before purchasing another battery make sure your charging system is working.

Neal, unless the parameters are met I can't see a solution (new battery needed!).

You said above; 'yes,i am updating it because its not working properly' what makes you point to the bios and nothing else.

What is the status of your Cmos battery, have you date and time showing correctly? If not then that could be the problem.
