The following modifications were made to the A03 BIOS to create A04:

discharged to 0%.
3. Fixed problem where 50W adapter was not correctly recognized
by the system.

function if connected to a HUB that also has a USB keyboard attached.
5. Fixed issue where the system may halt with a blue screen after
changing the password and accessing the drive.
6. Fixed potential issue where a flash failure may corrupt the ROM.

preventing some serial comms applications from working.

initiated from the start menu with USB Speakers attached.

booting to a CD-ROM drive.

zeros.
11. Fixed issue where system will lock while undocking after hot
docking with Windows 2000 and the PC-Tel modem installed.
12. Fixed issue where on battery resumes from hibernate the system
will message an error about an unsafe removal of the USB.

which a "No bootable devices" error is seen after entering
the correct password.
14. Fixed issue where system does not correctly detect the battery
when inserted and removed several times.
15. Fixed issue seen Windows 2000 and Windows XP where the USB may
re-enumerate after warm undock.
16. Fixed lock-ups seen when the BIOS password screen is repeatedly
aborted (ie wrong password entered) and the system re-suspends.
17. Fixed issue in which ACPI OSes do not always detect battery change.
18. Fix CMOS error seen on some Dell Systems at POST (invalid
CMOS configuration) after 3+ hours of reboots.
19. Fixed issue under ACPI OSes in which the battery may be reported
as charging even if the charger is disabled.
20. Fix problem that leads to intermittent hangs when playing DVDs
under Windows XP and Windows 2000.

Enhancements:
1. Added support for Windows NT 4.0
2. Prevent systems with 1Gb of RAM from doing suspend-to-disk.

of "F2" and "F12" keys.
4. Increased the amount of time before the system shuts down when
swapping batteries without AC power attached when in suspend mode.
5. Fixed potential Panasonic battery failures.
6. Added comments to power management help file to accurately reflect
support supplied for APM operating systems with and without
the Intel Speedstep applet loaded.
7. Allow changes to Touchpad/mouse settings in System Setup to take
effect immediately instead of requiring a reboot.
8. Added support for newer LCD panels.
Affected components: Brightness settings.
